FIELD OF THE INVENTION
This invention relates to a novel series of N-substituted tricyclic 3-aminopyrazole compounds and the use of such compounds to treat cell proliferative disorders, such as tumors, restenosis, rheumatoid arthritis, diabetic retinopathy, and the like. More particularly, the compounds are inhibitors of the PDGF receptor tyrosine kinase.
BACKGROUND OF THE INVENTION
Accumulating evidence supports the concept that loss of growth control of cancer cells involves perturbation of signaling pathways that in the normal cell are controlled by growth regulatory factors. Platelet-derived growth factor (PDGF) is a connective tissue cell mitogen that has been implicated in tumorigenesis (Ostman and Heldin, Adv. Can. Res., 80:1-38, 2001, and references therein) as well as a principal player in the complex process of angiogenesis that is critical for tumor growth.
PDGF exerts its cellular effects through binding to its specific receptor, PDGF-R. PDGF-R is a transmembrane receptor tyrosine kinase (RTK). It consists of two isozymes α and β. Each of these receptors has an extracellular part featuring five immunoglobulin-like domains and an intracellular part with a tyrosine kinase domain. Both α and β-containing receptors have been associated with mitogenic activity, stimulating edge ruffling and loss of stress fibers. Only the β-containing receptors has been associated with chemotaxis and actin reorganization (Heldin, C-H, EMBO Journal 11:4251-4259, 1992).
Binding of PDGF to PDGF-R results in dimerization of the two subunits of the PDGF-R receptors, thereby allowing autophosphorylation of each subunit on specific tyrosine residues in the cytoplasmic domain. The autophosphorylation leads to increased kinase activity and produces docking sites for a large number of signaling molecules with SH2 domains, such as Grb2/Sos1, PLC-gamma, GAP, PI-3 kinase and Src. (Heldin et al., Biochem. Biophys. Acta 1378:F79-113, 1998, and references therein). Upon binding to PDGF-R, these SH2 domain-containing signaling molecules initiate signal transduction pathways that are involved in different cellular responses such as cell proliferation, cell mobility, cell permeability or apoptosis.
PDGF has several important cellular effects in vivo. It regulates cell growth, differentiation, and migration during embryonal development, and plays a possible role in neuroprotection and regeneration. It also stimulates wound healing in adults. In addition, PDGF also has specialized functions in the vascular system as well as in the homeostasis of connective tissue (Ostman and Heldin, Adv. Can. Res., 80:1-38, 2001, and references therein).
Overactivity of PDGF has been implicated in the pathogenesis of a number of serious diseases, including cancers (glioma, lung, breast, colorectal, prostate, gastric and esophageal, leukemias and lymphomas), and other cell proliferative disorders, such as atherosclerosis, transplantation-induced vasculopathies, neointima formation, lung fibrosis, restenosis, pulmonary fibrosis, glomerulonephritis, glomerulosclerosis, congenital multicystic renal dysplasia, kidney fibrosis, and rheumatoid arthritis.(Ostman A, Heldin C H., Adv. Cancer Res, 80:1-38, 2001, and references therein).
A considerable body of direct and indirect experimental evidence showed that sustained tumor growth and metastasis are angiogenesis-dependent (see e.g., Hanahan, Science, 277:48-50, 1997). Angiogenesis is the development of new vasculature from preexisting blood vessels and/or circulating endothelial stem cells (see i.e., Springer et al., 1998). Angiogenesis plays a vital role in many physiological processes, such as embryogenesis, wound healing and menstruation. Angiogenesis also appears to be important in certain pathological events, such as solid tumor growth and metastasis, arthritis, psoriasis and diabetic retinopathy (Hanahan and Folkman, Cell, 86(3):353-364, 1996;).
Anti-angiogenic therapy is currently being studied as a way to interfere with tumor growth. Indeed, numerous studies in animal models have demonstrated striking effects in tumor growth inhibition by targeting angiogenic growth factors such as vascular endothelial growth factor (VEGF), acidic and basic fibroblast growth factor (aFGF, bFGF) and PDGF. The receptors for VEGF and PDGF belong to one super family of receptor tyrosine kinases. Therefore, in addition to their role in treating other cell proliferative disorders, clinically useful PDGF-R tyrosine kinase inhibitors are useful for antiangiogenic therapy and to control tumor cell proliferation.
Small molecule inhibitors of the receptor tyrosine kinase constitute a novel class of drugs with large potential (Druker and Lydon, J. Clin. Invest., 105:3-7, 2000, and references therein). Since 1995, a number of small molecule inhibitors for PDGF receptor autophosphorylation have been characterized. Some examples are listed below.
JP 06087834 (Zimmermann) discloses N-phenyl-2-pyrimidine-amine derivatives which have tumor inhibitory activity and are useful for treating tumors in warm-blooded animals including human beings. Derivatives of this group of compounds, compound CGP53716 (Buchdunger et al., PNAS, 92:2558-2562, 1995) and compound STI-571 (Buchdunger et al., Cancer Res, 56:100-4, 1996), have been shown to inhibit PDGF-R autophosphorylation.
JP 11158149 (Kubo et al.) discloses quinoline derivatives for the treatment of diseases such as tumors and diabetic retinopathy. Derivatives of this group of compounds, compound Ki6783 (Yagi et al., Exp. Cell Res. 243:285-292, 1997) and compound Ki6896 (Yagi et al., Gen. Pharmacol. 31:765-773, 1998), have been shown to inhibit PDGF-R autophosphorylation.
U.S. Pat. No. 5,932,580 (Levitzki et al.) discloses PDGF receptor kinase inhibitory compounds of the quinoxaline family including Tyrphostin, ATP-competitive inhibitors of the receptor kinase.
U.S. Pat. No. 5,409,930 (Spada, et al.) discloses bis mono- and/or bicyclic aryl and/or heteroaryl compounds exhibiting protein tyrosine kinase inhibition activity. Compound RPR01511A, a derivative of this group of compound, has been shown to inhibit PDGF-R autophosphorylation (Bilder et al., Circulation. 99(25):3292-9. 1999).

U.S. Pat. No. 5,476,851 (Myers, et al.) discloses Pyrazolo[3,4-g]quinoxaline compounds, as PDGF receptor protein tyrosine kinase inhibitors.
Compound SU-6668, an ATP competitive inhibitor, has been shown to inhibit PDGF-R autophosphorylation (Laird, et al., Cancer Res. 60:4152-4160, 2000].
WO01/79198 (Reich et al.) discloses amino-pyrazole compounds of the following formula that modulate and/or inhibit the activity of protein kinases.




WO0212242 (Fancelli et al.) discloses bicyclo-pyrazole compounds that are useful for treating diseases linked to disregulated protein kinases.
Up to now, STI-571 (GLEEVEC) is the only compound to reach market with significant PDGFR activity, although it is not a selective antagonist of this enzyme. Therefore, PDGF-R remains an extremely attractive target for the design of potent and selective small molecule inhibitors that will represent an important new class of therapeutic agents for the treatment of tumors and other cell proliferative disorders.

In general, IUPAC nomenclature rules are used throughout this disclosure. Nomenclature for radical substituents is derived by first indicating the functionality having the point of attachment with a hyphen, followed by the adjacent functionality toward the terminal portion of the side chain, as in:

—(C1-10)alkyl-C(O)NH—(C1-10)alkyl-Phenyl

or, when a lead hyphen is not used, by describing the terminal portion of the side chain first, followed by the adjacent functionality toward the point of attachment, as in:

phenyl-(C1-10)alkylamido(C1-10)alkyl, or

phenylalkylamidoalkyl

all three of which refer to a radical of the formula:





Where the are two point of attachment, for example in a linking group, or a ring member, the two points of attachment are indicated with a lead hyphen and a final hypen. For example, the points of attachment of a linking group having two monvalent radical centers would be indicated as —(CH2)2— or —O(CH2)2— and the like; and the points of attachment of a linking group having a single divalent radical center would be indicated as —NH— or —N(C═O alkyl)- and the like. Points of attachment for an aromatic ring member would be indicated as —N—., —S— or —CH— and the like, for example.
Where the phrase “terminating with” is used, the point of attachment for the terminal substituent is indicated by the second dash. For example, for the phrase “—C(═O)—(CH2CH2O—)1-10 terminating with —H, methyl, ethyl, or benzyl” the point of attachment for the selected terminal substituent is the terminal oxygen, for example, —C(═O)—(CH2CH2OH) or —C(═O)—(CH2CH2OCH2CH2OCH2CH2OCH3).
When a particular group is “substituted” (e.g., phenyl, aryl, heteroalkyl, heteroaryl), that group may have one or more substituents, preferably from one to five substituents, more preferably from one to three substituents, most preferably from one to two substituents, independently selected from the list of substituents.
With reference to substituents, the term “independently” means that when more than one of such substituents is possible, such substituents may be the same or different from each other.
It is intended that the definition of any substituent or variable at a particular location in a molecule be independent of its definitions elsewhere in that molecule. It is understood that substituents and substitution patterns on the compounds of this invention can be selected by one of ordinary skill in the art to provide compounds that are chemically stable and that can be readily synthesized by techniques known in the art as well as those methods set forth herein.

The compounds of the present invention may be prepared by any number of processes as described generally below and more specifically as described in the Examples which follow herein.
During any of the processes for preparation of the compounds of the present invention described herein, it may be necessary and/or desirable to protect sensitive or reactive groups on any of the molecules concerned (for example hydroxy, amino, thio, oxo or carboxy groups). This may be achieved by means of conventional protecting groups, such as those described in Protective Groups in Organic Chemistry, ed. J. F. W. McOmie, Plenum Press, 1973; and T. W. Greene & P. G. M. Wuts, Protective Groups in Organic Synthesis, John Wiley & Sons, 1991. The protecting groups may be removed at a convenient subsequent stage using methods known from the art.
Methods, of Synthesis
Methods of synthesizing the compounds of the present invention include, but are not limited to, the methods described below. The starting materials used in Methods A through E are generally, starting ketones of the Formula (S1)




wherein R1, R2, R3, p, q, and n are as described herein for Formula (I) Compounds of the formula (S1) are either known or commercially available compounds or compounds which may be prepared from known compounds by known chemistry.

Aromatic ketones may be prepared by the Friedel-Crafts reaction (See Practical Organic Chemistry by Vogel, Third Edition, pp 724-749). For example, Friedel-Crafts acylation of substituted aryl propanoic acids of formula (S1a), or their derivatives will yield substituted indan-1-ones of formula (S1b), as described in the literature. Similarly, Friedel-Crafts acylation of substituted aryl butanoic acids or their derivatives will yield substituted alpha-tetralones (For example, see Cho, H. et al., Heterocycles (1996), 43(1), 127-131; Baddeley et al., J. Chem. Soc, (1956), 4647; Reeve et al., J. Amer. Chem. Soc. (1951), 73, 1371)




Starting ketones of formula (S1b) may also be prepared from the oxidation of the corresponding alcohols of formula (S1c) or alkanes of formula (S1d) using various known oxidizing agents (For example, see Mandal, et al., Tetrahedron Lett, (1996), 37(21), 3769-3772; lshihara, et al., J. Org.Chem. (1997), 62(17), 5664-5665).




Starting pyridyl heteroaryl ketones may be prepared by condensation of diones of formula (S1e) or enaminones of formula (S1g) with propandiketals of formula (S1f) or propenaldehydes of formula (S1h), respectively (Examples see: Huang et al., Synth. Commun. (1998), 28(7), 1197-1200; Reimann et al., Pharmazie (1995), 50(9), 589-592).




Starting thienyl heteroaryl ketones may be prepared by Friedel-Crafts acylation of heteroarylpropanoic acids using aluminum chloride, polyphosphoric acid or trifouoroacetic acid etc. to provide the cyclized ketones. (For example see Cantrell et al., Tetrahedron Lett (1967), 4477; Muraro et al., C R Hebd Seances Acad Sci (1971), 273, 1362; Macdowell, et al., J. Org. Chem. (1967), 32, 1226; Binder, et al., Monatsh Chem (1998), 129(8), 887-896).

Starting pyrrolylketones may be prepared via intramolecular cyaloaddition of azomethide ylides with tethered alkynes as shown below (Nayyar, et al., J. Org. Chem. (1997), 62(4), 982-991). Alternatively, the starting pyrrole ketones may be prepared from diketones by reacting with α-bromoketones or alpha-bromopyruvates and then by carrying out Paal-Knorr cyclization with suitably substituted amines (For example, see Stojanovic et al., J. Serb. Chem. Soc. (1997), 62(9), 749-7530.)




Thiazolyl heteroaryl ketones may be prepared via the condensation of bromoketones with thioacetamides as described in Maillard, et al., Eur. J. Med. Chem. Ther (1984), 19 (5), 451.




Oxazole ketones and furanyl ketones may be prepared via Rhodium catalyzed cycloadditions of alpha-diazo-diketones with nitriles or acetylenes. Similarly, lodonium ylides may undergo Rh2(OAc)4 catalyzed thermal [3+2]-cycloaddition with acetylenes and nitriles to form the corresponding furans and oxazoles, respectively. (For example see Lee, et al., Heterocycles (1998), 48(5), 875-883; and Gogonas, et. al, Tetrahedron Lett. (2000), 41(48), 9299-9303).

N-Glucuronide Synthesis
To varying degrees the compounds of this invention may undergo the in vivo N-glucuronidation by various endogenous isozymes of the UDP-glucuronosyltransferase family (Chiu, S-HL; Huskey, S-EW; 1996 ASPET N-glucuronidation of xenobiotics symposium: Species differences in N-glucuronidation, Drug Metabolism and Disposition 1998, 26(9): 838-847).
One skilled in the art will understand that in vivo metabolites of compounds of Formulae (I) and (II) may be readily reverted to compounds of Formulae (1) and (II) by action of endogenous β-glucuronidase. The scientific literature details that tumor tissue generally contains elevated levels of endogenous β-glucuronidase. By action of endogenous β-glucuronidase, the in situ re-generation of compounds of Formulae (I) and (II) can be accomplished. In this way, the ability of the compounds of the present invention to be reversibly glucuronidated allows for the targeting of the present compounds to tumor tissue (Sperker, B; Backman, J T; Kroemer, H K, The role of β-glucuronidase in drug disposition and drug targeting in humans, Clin. Pharmacokinet., 1997, 33(1): 18-31).
Furthermore, reversible glucuronidation of the present compounds may also be recognized by one skilled in the art as a potential method for the detoxification of compounds of Formulae (I) and (II) (Caldwell, J; The significance of phase II conjugation reactions in drug disposition and toxicity, Life Sci, 1979, 24: 571-578), thus allowing the N-glucuronide metabolites formed to serve as a potential non-toxic reservoir for compounds of Formulae (I) and (II) which can then be readily unmasked to fully biologically active compounds of Formulae (I) and (II) in situ by tumor associated β-glucuronidase.
The N-glucuronide metabolites of compounds of Formulae (I) and (II) will have the structures shown below as GLU A, GLU B, and GLU C:







Usually, the glucuronidated compounds will have a β-configuration about the anomeric carbon atom, especially if the glucuronide is produced by well-established enzymatic methods known to persons skilled in the art (Luukkanen, L; Kilpelaeinen, I; Kangas, H; Ottoila, P; Elovaara, E; Taskinen, J, Enzyme-Assisted Synthesis and Structural Characterization of Nitrocatechol Glucuronides, Bioconjugate Chemistry (1999), 10(1), 150-154).
The N-glucuronides may also be prepared by direct synthesis by reacting compounds of Formulae (I) and (II) with suitably protected glucuronosyl halides by synthetic methodology know to persons skilled in the art (Upadhyaya, Pramod; Mclntee, Edward J.; Hecht, Stephen S., Preparation of Pyridine-N-glucuronides of Tobacco-Specific Nitrosamines., Chemical Research in Toxicology (2001), 14(5), 555-561).

Biological Activity
Biological Activities of the Compounds of the Invention
Compounds within the scope of this invention were subjected to various biological tests. Results of these tests showed that compounds within the scope of this invention inhibited PDGF-R kinase activity. Compounds within the scope of this invention also exhibited inhibitory activity against c-Abl kinase. In addition, compounds within the scope of this invention inhibited cell (including normal tissue cells, tumor cells and leukemia cells) proliferation in the presence or absence of PDGF stimulation. Other studies demonstrated that compounds within the scope of this invention inhibited angiogenesis and compounds were shown to have anti-tumor activity. Further, compounds within the scope of this invention sensitized tumor cells for radiation treatment. Pro-drugs of compounds within the scope of the invention were demonstrated to convert back to parent compounds in vivo.
The following representative assays were performed in determining the biological activities of compounds within the scope of the invention. They are given to illustrate the invention in a non-limiting fashion.
1. Inhibition of PDGF-Receptor Kinase Activity
PDGF-R kinase activity was assayed by its ability to phosphorylate one of its target proteins, PLCγ, in a cell-free system, in particular, a PLC1 peptide comprising the tyrosine residue where the phosphorylation occurs was used for the assay.
Materials
The following reagents were prepared for the assay:. 10× Kinase Buffer (500 mM Tris-HCl pH=8, 100 mM MgCl2, 1 mM Na3VO4); 10 mM DTT (final concentration at 1 mM in assay); 10 mM ATP (final concentration at 5 μM in assay); 33P-γ-ATP (Cat. No.: NEG/602H. 2000-3000 Ci/mmol) purchased from NEN; Purified, soluble, recombinant PDGF-receptor beta enzyme comprising the tyrosine kinase domain (from amino acid 545 to 1106 of GenBank Access NO: AAA36427) at 0.4 mg/mL; Enzyme Dilution Buffer (50 mM Tris-HCl pH=8.0, 0.1% BSA); Wash/Stop Buffer (PBS+100 mM EDTA); NEN Streptavidin Flashplates (Cat. No.: SMP-103) which binds to the biotinylated PLC1 peptide but not the PDGF-R enzyme; PLC1 peptide (Biotin-KHKKLAEGSAYEEV-Amide) at 1 mM in 50 mM Tris-HCL with pH of 8.0.
Procedure
Reagents were first mixed according the following regimen:

The above reaction mixture was dispensed into each well of a Flashplate at 70 μl/well. To test the effect of a compound on PDGF-R kinase activity, the test compound either in a fixed concentration or in serially diluted concentrations in 100% DMSO was added to appropriate wells at 1 μl/well.
Enzyme PDGF-R was diluted in Enzyme dilution buffer as following:
















Enzyme Dilution Buffer
3289 μl



PDGF-R enzyme
 100 μl










The kinase reaction was initiated by adding 30 μl of diluted PDGF-R enzyme solution to each well on the Flashplate containing hot ATP and PLC1, except wells of column 12 rows E through H, which were used to calculate the plate background. The Flashplate was swirled to mix and was incubated at 30° C. for 60 minutes. Then, the reaction mixture was discarded and the Flashplate was washed 3 times each with 200 μl Wash/Stop Buffer. Subsequently, each well on the Flashplate was filled with 200 μl of Wash/Stop buffer. The amount of 33P retained in each well was measured using a Packard TopCount after the plate was sealed with a transparent plate sealer.
When a test compound inhibited the PDGF-R kinase activity, the well containing such a compound contained less 33P as compared to the well without the compound. The percentage of inhibition of the test compound on PDGF-R kinase activity is defined as the amount of 33P retained in the well containing the compound divided by the amount of 33P in the well without the compound. Tested under the described assay conditions, more than 600 compounds within the scope of the invention at a final concentration of 10 μM have demonstrated inhibitory effect on PDGF-R kinase activity.
In order to test the potency of inhibition of present compounds, an IC50 for an individual compound was measured using the above procedure. As used herein, the IC50 for PDGF-R kinase activity refers to the concentration of an inhibitor at which the activity of the PDGF-R kinase is reduced by one-half as compared with reactions containing no inhibitor.
Inhibition of PDGF-R kinase activity preferably refers to an IC50 of less than or equal to about 75 μM using the assay described above. Preferably, the compound can inhibit PDGF-R kinase activity with an IC50 of less than or equal to about 10 μM, more preferably less than or equal to about 1 μM, most preferably less than or equal to about 0.1 μM. Lower IC50 values are preferred because the IC50 provides an indication as to the effectiveness of the compound. Other factors known in art, such as compound half-life, bio-distribution, and toxicity should also be considered for therapeutic uses. Such factors may enable a compound with a higher IC50 to have greater in vivo efficacy than a compound having a lower IC50.
Representative compounds of the present invention were tested for PDGF-R kinase activity with % inhibition and/or IC50 results as listed in Table A.

2. Inhibition of c-Abl Kinase Activity

Previous studies have shown that a selective PDGF-R kinase inhibitor STl-571 (supra) was also a selective inhibitor for c-Abl kinase activity and therefore was a selective inhibitor for the Bcr-Abl oncogene product (for a review on therapeutic interventions on Bcr-Abl see Kindler et al., 2002, Expert Opin Ther Targets; 6(1): 85-101). Variants of Bcr-Abl have been associated with distinct types of human leukemias, such as chronic myelogenous leukemia (CML); acute lymphocytic leukemia (ALL); chronic neutrophilic leukemia (CNL); acute undifferentiated leukemia (AUL); and acute myelogenous leukemia (AML) (Anjali et al., 2002, Leukemia Research, 26(8): 713-720). The inhibitory activity of compounds within the scope of the invention on c-Abl kinase activity was tested according to the following procedure.
Materials


    1. 10× Kinase Buffer [500 mM Tris-HCl pH=8, 100 mM MgCl2, 1 mM Na3VO4]
    2. 10 mM DTT [final concentration 1 mM]
    3. 10 mM ATP [final concentration 5 μM] (Gibco, Cat No:18330-019, Carlsbad, Calif.)
    4. 33P-γ-ATP [NEG-602H; 2000-3000 Ci/mmol], 2 μCuries per well at 10 μCi/μl (0.2 μl/well)
    5. Abl enzyme (New England Biolabs, Cat No. P6050L, Beverly, Mass.) at 100 Units/μu use 10 Units/well (0.1 μl/well)
    6. Enzyme Dilution Buffer [50 mM Tris-HCl pH=8.0, 0.1% BSA]
    7. Wash/Stop Buffer [PBS +100 mM EDTA]
    8. NEN Streptavidin Flashplates (New England Nuclear, Cat No. SMP-103, Boston, Mass.).
    9. Abl Peptide Substrate (Biotin-EAIYAAPFAKKK-amide) at 1 mM in 50 mM Tris-HCL pH=8.0. (Use at 1.0 μM).

Procedure



Reagents were first mixed according to the following regimen:

The above reaction mixture was dispensed into each well of a Flashplate at 70 μl/well. To test the effect of a compound on Abl kinase activity, the test compound either in a fixed concentration or in serially diluted concentrations in 100% DMSO was added to appropriate wells at 1 μl/well.
Enzyme Abl was diluted in enzyme dilution buffer as following:
















Enzyme Dilution Buffer
3289 μl



Abl enzyme (100 Units/μl)
 11 μl










The kinase reaction was started by adding 30 μl of diluted Abl enzyme solution to each well on the Flashplate containing hot ATP (2 μCi/well) and Abl peptide substrate (at 1 μM final conc.), except wells of column 12 rows E and F, which were used to calculate the plate background. The Flashplate was swirled to mix and was incubated at 30° C. for 60 minutes. Then, the reaction mixture was discarded and the Flashplate was washed 3 times each with 200 μL Wash/Stop Buffer. Subsequently, each well on the Flashplate was filled with 200 μl of Wash/Stop buffer. The amount of 33P retained in each well was measured using a Packard TopCount after the plate was sealed with a transparent plate sealer.
When a test compound inhibited c-Abl kinase activity, the well containing such the test compound contained less 33P as compared to the well without the compound. Tested under the described assay conditions, compounds within the scope of the invention demonstrated inhibitory effect on c-Abl kinase.
In order to test the potency of inhibition of present compounds, an IC50 for an individual compound was measured using the above procedure. As used herein, the IC50 for c-Abl kinase activity refers to the concentration of an inhibitor at which the activity of c-Abl kinase is reduced by one-half as compared with reactions containing no inhibitor. The IC50 for c-Abl kinase activity of individual representative compounds of the present invention are listed in Table B.

3. Anti-Cell Proliferation Assays

In addition to the above cell-free assays, the biological activities of the compounds of the invention were also measured in cell-based assays. One such assay is to measure the effect of the compound on cell proliferation in the presence or absence of PDGF stimulation in various cell types.
3a. Anti-Cell Proliferation in Normal Cells in the Presence of PDGF Stimulation
The effect of compounds of the invention on cell proliferation in normal human primary cells, in particular, cryopreserved human coronary artery smooth muscle cells (HCASMC), in the presence of PDGF stimulation was tested based on incorporation of 14C-thymidine into DNA of cells.
Materials
The following materials were purchased from their respective sources: Recombinant human PDGF beta homodimer, rhPDGF-BB (herein after referred as “PDGF-BB”) purchased from R&D System (Minneapolis, Minn., Cat. No 220-BB); Cryopreserved human coronary artery smooth muscle cells (HCASMC), tissue culture medium for HCASMC, and smooth muscle growth supplement (SMGS) purchased from Cascade Biologics (Portland, OR, HCASMC Cat. No: C-017-5C; Medium 231 Cat. No: M-231-500; and SMGS Cat. No: S-007-25); 96-well CytoStar tissue culture treated scintillating microplates purchased from Amersham (Piscataway, N.J., Cat. No: RPNQ0160); Methyl 14C-thymidine at 56 mCi/mmol (250 μCi/2.5 mL) purchased from NEN (Cat. No.: NEC568); DMSO from Sigma (St. Louis, Mo., Cat. No: D-5879); Sterile reagent reservoirs from Costar (VWF4 International, Inc., West Chester, Pa., Cat. No: 4870); Dulbecco's PBS from Gibco (Cat. No: 14190-136); Backing tape white plate cover for bottom of CytoStar plate from Packard (Cat. No: 6005199)
Procedure
HCASMC were seeded at approx. 4000 cells/well in a volume of 100 μi of complete Medium 231 with SMGS. Cells were grown for 48 hrs until they reach 80% confluence. They were then quiesced in SMGS-free Medium 231 for 24 hrs. Cell media were replenished with SMGS-free Medium 231 containing PDGF-BB at 50 ng/mL in a total volume of 100 μl/well; and 1 μl of test compounds in serially diluted concentrations in 100% DMSO was added to each well. For the maximum growth control wells, only 1 μl of 100% DMSO was added; for minimum growth (blank) wells, 1 μl of 10 mM cycloheximide was added to each well. After 24 hours incubation, 20 μl of 14C-thymidine mix was added to each well and the 14C-thymidine mix was made according the following regimen:

Cells were incubated for an additional 24 hrs in media containing test compounds, PDGF-BB and 14C-thymidine. Then, the reaction mixture was discarded and the plate was washed 3 times each with 200 μl PBS. Subsequently, each well on the plate was filled with 200 μl of PBS. The top of the plate was sealed with transparent plate sealer and white plate backing sealers were applied to the bottom of plates. The retained 14C inside each well was measured using a Packard TopCount.
The amount of 14C retained in a well correlates to the proliferation of cells inside the well. When a test compound inhibited PDGF-BB induced HCASMC proliferation, the well containing such a compound retained less 14C. as compared to the maximum growth control wells without the compound. In order to test the potency of inhibition of the present compound, IC50 of an individual compound on the inhibition of PDGF-BB induced HCASMC proliferation was measured using the above procedure. As used herein, said IC50 refers to the concentration of the test compound at which the amount of PDGF-BB induced HCASMC proliferation is reduced by one-half as compared to the maximum growth control wells without the compound. Table C shows examples of the IC50 for representative compounds of the invention.
3b. Anti-Cell Proliferation in Normal Cells in the Absence of PDGF Stimulation
The effect of compounds of the invention on cell proliferation in normal human primary cell, in particular, human umbilical vein endothelial cells (HUVEC), in the absence of PDGF stimulation was tested based on incorporation of BrdU into DNA of cells.
Materials:
The following materials were purchased from their respective sources: HUVEC cells from Cascade Biologics, Cat No: C-015-10C; Medium 200 from Cascade Biologics, Cat No: M-200-500; Low serum growth supplements (LSGS) from Cascade Biologics, Cat No: S-003-10; F12-K medium from Gibco/BRL, Cat No: 21127-022; BrdU kit from Roche, Cat No: 1 647 229; and Trypsin/EDTA solution from Cascade Biologics, Cat No: R-001-100.
Procedure
For propigation, HUVEC cells were grown in M-200 medium supplemented with LSGS. For studies, cells were detached with Trypsin/EDTA solution and washed three times with 10 mL of F12K (LS, low serum) medium and then centrifuged at 400×G for 5 minutes. F-12K (LS) medium is F-12K medium containing 0.2% heat-treated fetal bovine serum.
Cell concentration was adjusted to about 5×104 cells/mL in F-12K (LS) medium, and 200 μl (approx. 1×104 cells) were added to each well of a 96-well plate. Cells were then incubated for 16 to 20 hours at 37° C. under 95% air/5% CO2 to allow the cells to attach and become quiescent.
Cell proliferation was stimulated by adding 50 μL of a 1:10 dilution of LSGS in F12K (LS). Maximum-stimulated control wells were prepared by adding 50 μl of a 1:10 dilution of LSGS. Zero control wells contained 50 μL of F-12K (LS) medium only. Test compounds in 100% DMSO were added at a volume of 2.5 μl to achieve the desired final drug concentration. Replicates of eight wells per condition were tested. Cells were incubated at 37° C. overnight. On the next day 25 μL of BrdU (1:100 dilution of stock in F-12K (LS) medium) was added to each well.
Cells were incubated for an additional 20-24 hours. The medium was removed and the cells were fixed by adding 200 μL of FixDent solution (included in the BrdU kit) to each well and then incubated at room temperature for an additional 30 minutes. FixDent was removed by flicking and blotting the plates, and 100 μL of anti-BrdU-POD (included in the BrdU kit) diluted at a 1:100 dilution in antibody dilution solution (included in the BrdU kit) was added to each well. The diluted anti-BrdU-POD solution was prepared shortly before use. The plates were incubated at room temperature for 90 minutes.
The unbound antibody was removed by washing three times with Wash Solution (200 μL per wash). Wash Solution was prepared by making a 1:10 dilution of Wash Buffer Stock (included in the BrdU kit) with distilled water. Substrate solution (included in the BrdU kit) (100 uL) was added to each well and incubated for an additional 30-40 minutes. Plates were then read at 405 nm on a 96-well plate reader.
In order to test the potency of inhibition of the present compound, IC50 of an individual compound on the inhibition of PDGF-BB independent HUVEC proliferation was measured using the above procedure. As used herein, said IC50 refers to the concentration of the test compound at which the amount of HUVEC proliferation is reduced by one-half as compared to the maximum growth control wells without the compound. Table C shows examples of the IC50 for representative compounds of the invention.
3c. Anti-Cell Proliferation in Tumor Cells
The effect of compounds of the invention on cell proliferation in various tumor cells was tested based on incorporation of 14C-thymidine into DNA of cells.
Materials
Similar to those described above in 3a, except that different cells, cell growth medium, and growth supplements were used. Human tumor cell lines derived from various human tissue origins (LoVo from colon, H460 from lung, T47D from breast, PC3 from prostate, A375 from melanoma, AsPC1 from pancreas) were obtained from the American Type Culture Collection (ATCC) and cultured under specified conditions required for each cell type, as provided by ATCC. Complete medium was obtained from Cellgro: Iscove's medium with 10% Fetal Bovine Serium (FBS) (Mediatech, Inc., Herndon, Va. 20171, Cat. No. 10-016-CV).
Procedure
Tumor cells were seeded at approx. 3000-8000 cells per well in a volume of 100 μl of complete medium. Cells were grown for 24 hours in complete medium, and 1 μl of test compound was serially diluted in 100% DMSO and added to each well. For maximum growth control wells, only 1 μl of 100% DMSO was added. After 24 hours incubation, 20 μl of 14C-thymidine master mix was added to each well and the 14C-thymidine master mix was prepared according to the following regimen:

Cells were incubated for an additional 24 hours at 37° C. in medium containing test compound and 14C-thymidine. Then, the reaction mixture was discarded and the plate was washed 2 times each with 200 μl PBS. Subsequently, each well on the plate was filled with 200 μl of PBS. The top of the plate was sealed with transparent plate sealer and white plate backing sealers were applied to the bottom of plates. The retained 14C inside each well was measured using a Packard TopCount.
In order to test the potency of inhibition of the present compound, IC50 of an individual compound on the inhibition of tumor cell line proliferation was measured using the above procedure. As used herein, said IC50 refers to the concentration of the test compound at which the amount of tumor cell proliferation is reduced by one-half as compared to the maximum growth control wells without the compound.

3d. Anti-Cell Proliferation in Leukemia Cells
The effect of compounds of the invention on cell proliferation in leukemia cells, in particular, the human chronic myelogenous leukemia (CML) K562 cell line, was tested using flow cytometry and trypan blue exclusion cell counting assays. The CML K562 cell line has been found to express the oncogene bcr/abl, the genetic hallmark of human CML (Wu et al., 1995, Leukemia, 9(5): 8-862).
Material and Procedure
The human chronic myelogenous leukemia (CML) K562 cell line was obtained from American Type Culture Collection (ATCC) and cultured under specified conditions, as provided by ATCC. A Becton Dickinson FACSCalibur instrument was used for flow cytometry analyses. A CycleTEST PLUS DNA Reagent Kit (Cat. No. 340242, Becton Dickinson) was used in the study for cell staining. The standard operating procedure and a protocol for Cycle TEST PLUS DNA Reagent Kit from Becton Dickinson have been followed to carry out the study. Briefly, flow cytometric analysis of the differentially stained CML K562 cell line was used to estimate the DNA content and cell cycle phase distribution of cells treated with various concentrations of the compound for 24 hours. CML K562 cells treated with compound No. 14 were first stained with propidium iodide followed by fluorescence analysis to quantitate the cell cycle profile. Data analysis was carried out using the ModFit LT cell cycle data analysis program (Verity Software House, Topsham, Me. 04086, www.vsh.com). Cell viability test was performed using a Trypan Blue exclusion assay (Trypan Blue from Sigma, Cat No. T 0776) following procedures known to those skilled in the art.
Flow cytometry spectra demonstrated that after 24 hours of treatment the compound caused accumulation of cells in the G2/M phase of the cycle and growth arrest of human CML K562 cells in a concentration-dependent fashion (Table D).

Cell viability studies using the trypan blue exclusion assay demonstrated that treating the K562 cells with compound No. 14 for 24 hours caused a concentration-dependent decrease of cell proliferation in K562 cells. The IC50 for compound No. 14 on K562 (i.e., the concentration of the compound at which the amount of K562 cell proliferation is reduced by one-half as compared to the maximum growth control without the compound) was about 10 nM as measured from the trypan blue exclusion assay.
Using similar protocols in flowcytometry and trypan blue exclusion cell counting assays, it was found that compound No. 14 also blocked growth of other cell types such as H460 and LoVo in the G2/M cell cycle phase.
Any compound within the scope of the invention could be tested for their ability to inhibit cell proliferation using various protocols described herein.
4. Anti-Angiogenesis Assay.
Angiogenesis inhibitory activity of a compound of this invention can be measured in vivo using the matrigel mouse model (MM Assay) of angiogenesis (Passaniti et al., Laboratory Investigation, 67: 519-528, 1992). The matrigel mouse assay is a well-established method to quantify angiogenesis (see e g. Capogrossi et al., Methods in Molecular Medicine, Vascular Disease: Molecular Biology and Gene Therapy Protocols, Edited by: A. H. Baker, Humana Press Inc., Totowa, N.J., 1999). The model has been characterized extensively for its relevance as a mimic of the process of angiogenesis and has been used extensively to evaluate in vivo both potential angiogenic and anti-angiogenic activity of numerous compounds/agents. Compounds with demonstrated anti-angiogenic activity in other angiogenesis models (eg. RAR assay) have been shown to be potent inhibitors of angiogenesis in the MM assay and produce tumor growth reduction in human tumor xenograft models. All procedures involving animals were conducted in an animal facility fully accredited by the American Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC) and in accordance with The Guide for the Care and Use of Laboratory Animals (NIH). Protocols were approved by the RWJ-PRI Internal Animal Care and Use Committee (IACUC).
Procedure
Normal male mice (C57BU6J) were injected subcutaneously (ventrally below rib cage at abdominal midline) with 1.0 mL of chilled matrigel supplemented with a single purified pro-angiogenic growth factor (100-500 ng/mL of either rhPDGF-BB (supra), recombinant human basic fibroblast growth factor, rhFGF-basic (R&D System Cat. No 233-FB) or recombinant human vascular endothelial growth factor, rhVEGF (PanVera Cat. No R2951) and heparin (35 U/mL). Compounds are formulated as 0.1% suspensions (1 mg/mL final concentration) in 0.5% methylcellulose. Vehicle or test compounds (8-10 mice per treatment group) were administered orally by gavage beginning two hours after matrigel injections. Dosing continued for three consecutive days (ie. qd dosing on day 1, bid dosing on day 2, and bid dosing on day 3). Approximately. 18 hours after the last dose of vehicle or drug, mice were euthanized and the matrigel plugs were surgically removed intact (overlying skin removed and plug cut out retaining some of the peritoneal lining for support). The plug was placed in pre-labeled tubes containing 1.0 mL distilled water, minced and extracted for hemoglobin (Hb) overnight in a 37° C. water bath with light shaking. The tubes were centrifuged the next day at 3000 rpm for 20 minutes. Supernatants were removed and the hemoglobin concentration in the plug extract was measured spectrophotometrically using the Drabkin's assay method (Drabkin's reagent kit 525-A; SIGMA) and read on a Beckman DU 7400 Spectrophotometer. Hemoglobin content of the plug was used as an indirect index of the angiogenic response and a reduction of plug hemoglobin content was indicative of in vivo anti-angiogenic activity. The ability of compounds to inhibit PDGF-BB-stimulated angiogenesis in vivo was compared directly to vehicle-treated control mice. Group differences were analyzed statistically using the Mann-Whitney Test, with a p-value of 0.05 or less considered statistically significant.
Any compound within the scope of the invention can be tested using the in vivo MM assay protocol described herein. Results for representative compounds of the invention from the in vivo MM assay supplemented with PDGF are shown in Table E.

5. Anti-Tumor Assay

The anti-tumor activity of experimental compounds was evaluated in vivo using the human tumor nude mouse xenograft model. All procedures involving animals were conducted in an animal facility fully accredited by the American Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC) and in accordance with The Guide for the Care and Use of Laboratory Animals (NIH). Protocols were approved by the RWJ-PRI Internal Animal Care and Use Committee (IACUC).
Human tumor cell lines (LoVo, MDA-MB-231, H460 etc.) were obtained from American Type Culture Collection and cultured under specified conditions required for each cell type. Female athymic nude mice (Charles River nu/nu) were injected subcutaneously in the inguinal region of the thigh with 1-2×106 tumor cells in 0.1 mL volume on day zero. For growth delay studies, mice were dosed orally with vehicle (control group) or experimental drugs beginning three days after tumor cell inoculation. Compounds were prepared in 0.5% methylcellulose and treatments were administered bid for 30-35 consecutive days. Tumor growth was measured twice a week using calipers for the duration of the treatment. Tumor areas (mm2) were calculated as a product of length ×width. Body weights were obtained twice a week and loss of body weight was used as a measure of gross toxicity. At study termination, mice were euthanized and solid tumors were surgically excised intact and weighed. Final tumor weight served as the primary efficacy endpoint. Differences between treated and control mice were analyzed statistically by ANOVA and Dunnett's t-test.
Any compound within the scope of the invention can be tested in vivo using the human tumor nude mouse xenograft model described herein. A representative compound, compound No. 14, inhibited tumor growth by 72% with 50 mg/kg of the drug from the in vivo human tumor nude mouse xenograft model study.
6. Treatment in Combination with Irradiation
Radiotherapy is a major therapeutic modality in treating many types of cancers including human prostate and ovarian cancers. The anti-proliferative activity of compounds within the scope of the invention was tested in combination with irradiation treatment. A clonogenicity assay was performed on two different human cancer cell lines, DU145 (prostate cancer) and MDAH2774 (ovarian cancer) after the combined treatment of irradiation and a representative compound of the invention, compound No. 14.
Materials:
Cells DU145 (prostate cancer) and MDAH2774 (ovarian cancer) were obtained from ATCC; growth media MEM medium. (Mediatech, Herndon, Va.) was supplemented with 8% FBS, 50 U/ml penicillin and 50 μl g/ml Streptomycin (Hyclone, Logan, Utah), 2 mM L-glutamine (Hyclone, Logan, Utah), 25 mM HEPES (Hyclone, Logan, Utah); McCoy's 5A medium (Mediatech, Herndon, Va.) was supplemented with 8% FBS, 50 U/ml penicillin and 50 μg/ml-Strep (Hyclone, Logan, Utah) and Glutamine 2 mM L-glutamine (Hyclone, Logan, Utah), 137Cs γ-source was a Gammacell 1000 Elite irradiator (MDS Nordion, Kanata, Ontario, Canada); DMSO; 1×PBS; Methanol; 0.25% Crystal Violet, and 60 mm tissue culture dishes.
Procedure:
DU145 or MDAH2774 cells at desired cell number were plated in early log phase on 60 mm dishes in MEM medium supplemented with 8% FBS, Penicillin, Streptomycin, L-glutamine, or McCoys medium supplemented with 8% FBS, Penicillin, Streptomycin and Glutamine, respectively. Cells were plated in triplicate. Compound No. 14 at various concentrations was added to the cells 14 h after the plating. The final concentrations of the compound in the cell media ranged from 1 to 100 nM. After 24 h incubation with the test compound plates were split in two groups of equal size. The plates in the first group were irradiated with 7.3 Gy (plates containing DU145 cells) or 5.4 Gy (plates containing MDAH2774 cells) using a 137Cs γ-source (dose rate 3.32 Gy/min). The second group of plates were treated identically but not irradiated. Cells were incubated for an additional 24 hours in medium containing test compound. Then, the cells were replenished with fresh compound-free identical medium and allowed to grow for an additional 11 days. Cells were then fixed with methanol, stained with 0.25% crystal violet, and the clones containing more than 50 cells were counted.
The results from these studies showed that starting at the 30 nM concentration, compound No. 14 showed marked inhibitory activities against colony formation in both DU145 and MDAH2774 cells in the presence or absence of radiation, but clearly the inhibitory effect was greater with radiation (Table F). The activity appeared to be concentration-dependent with more dramatic effects achieved at 100 nM compound with radiation in either cell line. The results are consistent with the observation that compound No. 14 caused G2/M growth arrest in proliferating cancer cells, because cells under G2/M growth arrest are expected to be more vulnerable and sensitive to additional insult, such as radiation.
Any compound within the scope of the invention could be tested for their ability to sensitize cells for radiation treatment using the protocols described herein.

This study indicated that cancer cells that were pre-treated with low concentrations of compound of the invention showed a greater reduction of colony formation in combination with radiation, compared to either compound or irradiation alone. These preliminary studies support the principal of using compound of the invention in combination with radiation therapy in cancers where radiotherapy is a standard therapeutic modality.
7. Conversion of Pro-Drugs to Parent Compounds
It has been demonstrated that the chemical modification of an active agent can significantly change the chemical-physical properties such as solubility, stability, absorption, transport and bio-availability in terms of a particular biospace (see Bioreversible Carrier in Drug Design, by Edward B. Roche, Pergamon Press, 1987). Prodrugs are molecules that can be reversibly hydrolyzed back to the active agent by enzymes such as esterases. Pro-drugs of compounds within the scope of the invention were evaluated in in vitro and in vivo assay systems for their possible in vivo conversion to parent compounds.
Various pro-drugs of a representative compound of the invention, compound No. 14, were incubated in freshly prepared rat plasma for 2 hours. The PDGF-R kinase inhibitory activities of these pro-drugs were assayed prior to and after the plasma incubation. The PDGF-R kinase inhibition assay was performed as described supra. It was shown that 2h incubation in plasma increased the PDGF-R kinase inhibitory activity of the pro-drugs significantly. This suggests that a significant amount of pro-drug had been converted to the parent drug in rat plasma. Indeed, a significant amount of parent compound had been detected by HPLC analyses following the 2 h incubation with rat plasma (Table G).
Furthermore, pro-drugs have been administered orally to rats (10 mg/kg) in pharmacokinetics studies, and the conversion of pro-drugs to the parent compound was monitored by HPLC/MS/MS analyses. Parent compound or the glucuronide conjugates of the parent compound was detected in the rat plasma from the pharmacokinetics studies (Table G).

The conversion of pro-drugs to any parent compound within the scope of the invention could be tested using the protocols described herein.
Methods of use of the Compounds of the Invention
Compounds of the invention can be used in methods of treatment/ prevention for cell proliferation disorders or a disorder related to PDGF-R. They can also be used in methods of identifying new PDGF-R inhibitors, for example via rational design.
1. Methods of Identifying Novel PDGF-R Kinase Inhibitors Based on Rational Design.
In one aspect of this invention, compounds of the invention can be used to identify novel PDGF-R kinase inhibitors based on rational design.
As used herein, “rational design” refers to the process of designing a PDGF-R kinase inhibitor based on the three-dimensional structure of an inhibitor of PDGF-R kinase, preferably the method involving the three-dimensional structure of an inhibitor of PDGF-R kinase complexed with a PDGF-R protein, preferably a human PDGF-R protein, and more preferably a kinase catalytic domain of human PDGF-R protein. As used herein, “PDGF-R kinase catalytic domain” refers to a polypeptide consisting of a minimal amino acid sequence required for PDGF-R kinase activity, wherein the minimal amino acid sequence required for PDGF-R kinase activity can be readily determined by those skilled in the art. The catalytic domain can be that of a PDGF-R from human or an animal. For example, the “PDGF-R kinase catalytic domain” can comprise amino acid 545 to 1106 of GenBank Access NO: AAA36427.
Structure based rational design has been used successfully for identifying novel small molecule inhibitors for a variety of enzymes, such as proteases and protein tyrosine phosphatases. A method for identifying novel PDGF-R kinase inhibitors based on rational design comprises the steps of: (a) determining a three-dimensional structure of the compound of Formula I or II in the absence or presence of a polypeptide comprising the PDGF-R kinase catalytic domain; (b) analyzing the three-dimensional structure for the compound alone or for the intermolecular interaction between said compound and PDGF-R; (c) selecting a compound that mimics the structure for the compound alone or incorporates the predictive interaction; (d) synthesizing said designed compound; and (e) determining the ability of the molecule to bind and inhibit PDGF-R kinase activity. These steps can be repeated to obtain the optimal compounds by fine tuning the interaction features.
The three-dimensional structure can be obtained by, for example, X-ray crystallography, nuclear magnetic resonance, or homology modeling, all of which are well-known methods.
A particular method of the invention comprises analyzing the three-dimensional structure for the intermolecular interaction between said compound and PDGF-R, preferably the active kinase domain of PDGF-R. The present invention encompasses the use of information of the three-dimensional structure of the compound of Formula (I) or (II) complexed with PDGF-R in molecular modeling software systems to assist in analyzing intermolecular interactions. The likely binding site on PDGF-R as well as the key residues on the compound of Formula (I) or (II), which are critical for the intermolecular interaction, will be identified and analyzed.
Another particular method of the invention comprises designing a compound that incorporates the predictive interaction identified above. Such computer-assisted modeling and drug design may utilize information such as chemical conformational analysis, electrostatic potential of the molecules, protein folding, etc. Therefore, depending on the intermolecular interaction between the compound of Formula (I) or (II) and PDGF-R, novel PDGF-R kinase inhibitors will be designed to allow the specific binding of the designed compound to PDGF-R. The compound of Formula (I) or (II) may serve as a template for the initial design.
Another particular method of the invention comprises synthesizing the designed compounds that incorporate the predictive interaction identified above. Such a class of compounds can be synthesized using a variety of methods known in the art. For example, the synthesis methods described herein or the modification of these methods may prove to be useful to synthesize the designed compounds.
Yet another particular method of the invention comprises assaying the new compounds for their ability to bind and inhibit PDGF-R activity. The ability of a compound to inhibit PDGF-R kinase activity can be measured using any of the biological assays described supra, including the cell-free PDGF-R kinase assay; the PDGF-BB stimulated HCASMC cell proliferation and the human tumor cell proliferation assay; the in vivo anti-angiogenesis MM assay; and the human tumor mouse xenograft assay.
Because compounds within the scope of the invention also exhibited inhibitory activity for the c-Abl kinase, novel c-Abl kinase inhibitors can be identified by rational design using procedure similar to that described herein. Such a method comprises the steps of:

    
    
        (a) determining a three-dimensional structure of the compound of Formula I or II in the absence or presence of a polypeptide comprising the c-Abl kinase catalytic domain;
        (b) analyzing the three-dimensional structure for the compound alone or for the intermolecular interaction between said compound and c-Abl;
        (c) selecting a compound that mimics the structure for the compound alone or incorporates the predictive interaction;
        (d) synthesizing said designed compound; and
        (e) determining the ability of the molecule to bind and inhibit c-Abl kinase activity.

2. Methods of Treatment/Prevention

    
    


In another aspect of this invention, compounds of the-invention can be used to inhibit or reduce PDGF-R kinase or c-Abl kinase activity in a cell or a subject, or to treat disorders related to PDGF-R or cell proliferation in a subject.
In one embodiment to this aspect, the present invention provides a method for reducing or inhibiting the kinase activity of PDGF-R or c-Abl in a cell comprising the step of contacting the cell with a compound of Formula (I) or (II). The present invention also provides a method of inhibiting the kinase activity of PDGF-R or c-Abl in a subject comprising the step of administering a compound of Formula (I) or (II) to the subject. The present invention further provides a method of inhibiting cell proliferation in a cell comprising the step of contacting the cell with a compound of Formula (I) or (II).
The kinase activity of PDGF-R or c-Abl in a cell or a subject can be determined by procedures well known in the art, such as the PDGF-R kinase assay or the c-Abl kinase assay described supra.
The term “subject” as used herein, refers to an animal, preferably a mammal, most preferably a human, who has been the object of treatment, observation or experiment.
In other embodiments to this aspect, the present invention provides both prophylactic and therapeutic methods for treating a subject at risk of (or susceptible to) developing a cell proliferative disorder or a disorder related to PDGF-R.
In one example, the invention provides methods for preventing in a subject a cell proliferative disorder or a disorder related to PDGF-R, by administering to the subject prophylactically effective amount of a pharmaceutical composition comprising the compound of Formula (I) or (II) and a pharmaceutically acceptable carrier. Administration of said prophylactic agent can occur prior to the manifestation of symptoms characteristic of the cell proliferative disorder or disorder related to PDGF-R, such that a disease or disorder is prevented or, alternatively, delayed in its progression.
In another example, the invention pertains to methods of treating in a subject a cell proliferative disorder or a disorder related to PDGF-R by administering to the subject therapeutically effective amount of a pharmaceutical composition comprising the compound of Formula (I) or (II) and a pharmaceutically acceptable carrier. Administration of said therapeutic agent can occur concurrently with the manifestation of symptoms characteristic of the disorder, such that said therapeutic agent serves as a therapy to compensate for the cell proliferative disorder or disorders related to PDGF-R.
The term “prophylactically effective amount” refers to an amount of an active compound or pharmaceutical agent that inhibits or delays in a subject the onset of a disorder as being sought by a researcher, veterinarian, medical doctor or other clinician.
The term “therapeutically effective amount” as used herein, refers to an amount of active compound or pharmaceutical agent that elicits the biological or medicinal response in a subject that is being sought by a researcher, veterinarian, medical doctor or other clinician, which includes alleviation of the symptoms of the disease or disorder being treated.
Methods are known in the art for determining therapeutically and prophylactically effective doses for the instant pharmaceutical composition.
As used herein, the term “composition” is intended to encompass a product comprising the specified ingredients in the specified amounts, as well as any product which results, directly or indirectly, from combinations of the specified ingredients in the specified amounts.
As used herein, the terms “disorders related to PDGF-R”, or “disorders related to PDGF receptor”, or “disorders related to PDGF receptor tyrosine kinase” shall include diseases associated with or implicating PDGF-R activity, for example, the overactivity of PDGF-R, and conditions that accompany with these diseases. The term “overactivity of PDGF-R” refers to either 1) PDGF-R expression in cells which normally do not express PDGF-R; 2) PDGF expression by cells which normally do not express PDGF; 3) increased PDGF-R expression leading to unwanted cell proliferation; 4) increased PDGF expression leading to unwanted cell proliferation; or 5) mutations leading to constitutive activation of PDGF-R. Examples of “disorders related to PDGF-R” include disorders resulting from over stimulation of PDGF-R due to abnormally high amount of PDGF or mutations in PDGF, or disorders resulting from abnormally high amount of PDGF-R activity due to abnormally high amount of PDGF-R or mutations in PDGF-R. It is known that overactivity of PDGF has been implicated in the pathogenesis of a number of serious diseases, including cancers (glioma, lung, breast, colorectal, prostate, gastric and esophageal, leukemias and lymphomas), and other cell proliferative disorders, such as atherosclerosis, transplantation-induced vasculopathies, neointima formation, lung fibrosis, restenosis, pulmonary fibrosis, glomerulonephritis, glomerulosclerosis, congenital multicystic renal dysplasia, kidney fibrosis, and rheumatoid arthritis (Ostman A, Heldin C H., Adv. Cancer Res, 80:1-38, 2001, and references therein).
The term “cell proliferative disorders” refers to unwanted cell proliferation of one or more subset of cells in a multicellular organism resulting in harm (i.e., discomfort or decreased life expectancy) to the multicellular organisms. Cell proliferative disorders can occur in different types of animals and humans. For example, as used herein “cell proliferative disorders” include neoplastic and other cell proliferative disorders. As used herein, a “neoplastic disorder” refers to a tumor resulting from uncontrolled cellular overgrowth. Examples of neoplastic disorders include but are not limited to cancers such as, glioma cancers, lung cancers, breast cancers, colorectal cancers, prostate cancers, gastric cancers, esophageal cancers, colon cancers, pancreatic cancers, ovarian cancers, myelodysplasia, multiple myeloma, leukemias and lymphomas. Examples of leukemias include, but are not limited to chronic myelogenous leukemia (CML); acute lymphocytic leukemia (ALL); chronic neutrophilic leukemia (CNL); acute undifferentiated leukemia (AUL); and acute myelogenous leukemia (AML). Examples of other cell proliferative disorders, include but are not limited to, atherosclerosis, transplantation-induced vasculopathies, neointima formation, lung fibrosis, macular degeneration, restenosis, pulmonary fibrosis, glomerulonephritis, glomerulosclerosis, congenital multicystic renal dysplasia, kidney fibrosis, diabetic retinopathy and rheumatoid, arthritis.
In a further embodiment to this aspect, the invention encompasses a combination therapy for treating or inhibiting the onset of a cell proliferative disorder or a disorder related to PDGF-R in a subject. The combination therapy comprises administering to the subject a therapeutically or prophylactically effective amount of the compound of Formulae (I) or (II), and one or more other anti-cell proliferation therapy including chemotherapy, radiation therapy, gene therapy and immunotherapy.
In an embodiment of the present invention, the compound of the present invention may be administered in combination with chemotherapy. As used herein, chemotherapy refers to a therapy involving a chemotherapeutic agent. A variety of chemotherapeutic agents may be used in the combined treatment methods disclosed herein. Chemotherapeutic agents contemplated as exemplary including, but not limited to, adriamycin, dactinomycin, mitomycin, carminomycin, daunomycin, doxorubicin, tamoxifen, taxol, taxotere, vincristine, vinblastine, vinorelbine, etoposide (VP-16), 5-fluorouracil (5FU), cytosine arabinoside, cyclophohphamide, thiotepa, methotrexate, camptothecin, herceptin, actinomycin-D, mitomycin C, cisplatin (CDDP), aminopterin, combretastatin(s) and derivatives and prodrugs thereof.
In another embodiment of the present invention, the compound of the present invention may be administered in combination with radiation therapy. As used herein, “radiation therapy” refers to a therapy that comprises exposing the subject in need thereof to radiation. Such therapy is known to those skilled in the art. The appropriate scheme of radiation therapy will be similar to those already employed in clinical therapies wherein the radiation therapy is used alone or in combination with other chemotherapeutics.
In another embodiment of the present invention, the compound of the present invention may be administered in combination with a gene therapy. As used herein, “gene therapy” refers to a therapy targeting on particular genes involved in tumor development. Possible gene therapy strategies include the restoration of defective cancer-inhibitory genes, cell transduction or transfection with antisense DNA corresponding to genes coding for growth factors and their receptors, or with the so-called ‘suicide genes’.
In other embodiments of this invention, the compound of the present invention may be administered in combination with an immunotherapy. As used herein, “immunotherapy” refers to a therapy targeting particular protein involved in tumor development via antibodies specific to such protein. For example, monoclonal antibodies against vascular endothelial growth factor have been used in treating cancers.
Where a second pharmaceutical is used in addition to the compound of the invention, the two pharmaceuticals may be administered together in a single composition, separately, sequentially, at approximately the same time, or on separate dosing schedules.
As will be understood by those of ordinary skill in the art, the appropriate doses of chemotherapeutic agents will be generally similar to or less than those already employed in clinical therapies wherein the chemotherapeutics are administered alone or in combination with other chemotherapeutics. By way of example only, agents such as cisplatin, and other DNA alkylating agents are used widely to treat cancer. The efficacious doses of cisplatin used in clinical applications is of 20 mg/m 2for 5 days every three weeks for a total of three courses. Cisplatin is not absorbed orally and must therefore be delivered via injection intravenously, subcutaneously, intratumorally or intraperitoneally. Further useful agents include compounds that interfere with DNA replication, mitosis and chromosomal segregation. Such chemotherapeutic compounds including adriamycin, also known as doxorubicin, etoposide, verapamil, podophyllotoxin, and the like, are widely used in a clinical setting for the treatment of neoplasms. These compounds are administered through bolus injections intravenously at doses ranging from 25-75 mg/m 2 at 21 day intervals for adriamycin, to 35-50 mg/m 2for etoposide intravenously or double the intravenous dose orally. Agents that disrupt the synthesis and fidelity of polynucleotide precursors such as 5-fluorouracil (5-FU) are preferentially used to target neoplastic cells. Although quite toxic, 5-FU is commonly used via intravenous administration with doses ranging from 3 to 15 mg/kg/day.
The compound of the invention can be administered to a subject systemically, for example, intravenously, orally, subcutaneously, intramuscular, intradermal, or parenterally. The compound of the invention can also be administered to a subject locally. Non-limiting examples of local delivery systems include the use of intraluminal medical devices that include intravascular drug delivery catheters, wires, pharmacological stents and endoluminal paving. The compound of the invention can further be administered to a subject in combination with a targeting agent to achieve high local concentration of the compound at the target site. In addition, the compound may be formulated for fast-release or slow-release with the objective of maintaining the drugs or agents in contact with target tissues for a period ranging from hours to weeks.
The present invention also provides a pharmaceutical composition comprising the compound of Formula (I) or (II), or an optical isomer, enantiomer, diastereomer, racemate or pharmaceutically acceptable salt thereof, in association with a pharmaceutically acceptable carrier. The pharmaceutical composition may contain between about 0.1 mg and 1000 mg, preferably about 100 to 500 mg, of the compound, and may be constituted into any form suitable for the mode of administration selected. The phrases “pharmaceutically acceptable” refer to molecular entities and compositions that do not produce an adverse, allergic or other untoward reaction when administered to an animal, or a human, as appropriate. Veterinary uses are equally included within the invention and “pharmaceutically acceptable” formulations include formulations for both clinical and/or veterinary use. Carriers include necessary and inert pharmaceutical excipients, including, but not limited to, binders, suspending agents, lubricants, flavorants, sweeteners, preservatives, dyes, and coatings. Compositions suitable for oral administration include solid forms, such as pills, tablets, caplets, capsules (each including immediate release, timed release and sustained release formulations), granules, and powders, and liquid forms, such as solutions, syrups, elixirs, emulsions, and suspensions. Forms useful for parenteral administration include sterile solutions, emulsions and suspensions.
The pharmaceutical composition of the present invention also includes a pharmaceutical composition for slow release of the compound of the invention. The composition includes a slow release carrier (typically, a polymeric carrier) and a compound of the invention. Slow release biodegradable carriers are well known in the art. These are materials that may form particles that capture therein an active compound(s) and slowly degrade/dissolve under a suitable environment (e.g., aqueous, acidic, basic, etc) and thereby degrade/dissolve in body fluids and release the active compound(s) therein. The particles are preferably nanoparticles (i.e., in the range of about 1 to 500 nm in diameter, preferably about 50-200 nm in diameter, and most preferably about 100 nm in diameter).
The present invention also provides methods to prepare the pharmaceutical compositions of this invention. Compound of Formulae (I) or (II) or an optical isomer, enantiomer, ester, diastereomer, racemate or racemic mixture thereof, and salt thereof, as the active ingredient, is intimately admixed with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques, which carrier may take a wide variety of forms depending on the form of preparation desired for administration, e.g., oral or parenteral such as intramuscular. In preparing the compositions in oral dosage form, any of the usual pharmaceutical media may be employed. Thus, for liquid oral preparations, such as for example, suspensions, elixirs and solutions, suitable carriers and additives include water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents and the like; for solid oral preparations such as, for example, powders, capsules, caplets, gelcaps and tablets, suitable carriers and additives include starches, sugars, diluents, granulating agents, lubricants, binders, disintegrating agents and the like. Because of their ease in administration, tablets and capsules represent the most advantageous oral dosage unit form, in which case solid pharmaceutical carriers are obviously employed. If desired, tablets may be sugar coated or enteric coated by standard techniques. For parenterals, the carrier will usually comprise sterile water, though other ingredients, for example, for purposes such as aiding solubility or for preservation, may be included. Injectable suspensions may also be prepared, in which case appropriate liquid carriers, suspending agents and the like may be employed. In preparation for slow release, a slow release carrier, typically a polymeric carrier, and a compound of the invention are first dissolved or dispersed in an organic solvent. The obtained organic solution is then added into an aqueous solution to obtain an oil-in-water-type emulsion. Preferably, the aqueous solution includes surface-active agent(s). Subsequently, the organic solvent is evaporated from the oil-in-water-type emulsion to obtain a colloidal suspension of particles containing the slow release carrier and the compound of the invention.
The pharmaceutical compositions herein will contain, per dosage unit, e.g., tablet, capsule, powder, injection, teaspoonful and the like, an amount of the active ingredient necessary to deliver an effective dose as described above. The pharmaceutical compositions herein will contain, per unit dosage unit, e.g., tablet, capsule, powder, injection, suppository, teaspoonful and the like, from about 0.01 mg to 200 mg/kg of body weight per day. Preferably, the range is from about 0.03 to about 100 mg/kg of body weight per day, most preferably, from about 0.05 to about 10 mg/kg of body weight per day. The compounds may be administered on a regimen of 1 to 5 times per day. The dosages, however, may be varied depending upon the requirement of the patients, the severity of the condition being treated and the compound being employed. The use of either daily administration or post-periodic dosing may be employed.
Preferably these compositions are in unit dosage forms such as tablets, pills, capsules, powders, granules, sterile parenteral solutions or suspensions, metered aerosol or liquid sprays, drops, ampoules, auto-injector devices or suppositories; for oral parenteral, intranasal, sublingual or rectal administration, or for administration by inhalation or insufflation. Alternatively, the composition may be presented in a form suitable for once-weekly or once-monthly administration; for example, an insoluble salt of the active compound, such as the decanoate salt, may be adapted to provide a depot preparation for intramuscular injection. For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical carrier, e.g. conventional tableting ingredients such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate or gums, and other pharmaceutical diluents, e.g. water, to form a solid preformulation composition containing a homogeneous mixture of a compound of the present invention, or a pharmaceutically acceptable salt thereof. When referring to these preformulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective dosage forms such as tablets, pills and capsules. This solid preformulation composition is then subdivided into unit dosage forms of the type described above containing from 0.1 to about 500 mg of the active ingredient of the present invention. The tablets or pills of the novel composition can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permits the inner component to pass intact into the duodenum or to be delayed in release. A variety of material can be used for such enteric layers or coatings, such materials including a number of polymeric acids with such materials as shellac, acetyl alcohol and cellulose acetate.
The liquid forms in which the compound of Formulae (I) or (II) may be incorporated for administration orally or by injection include, aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil or peanut oil, as well as elixirs and similar pharmaceutical vehicles. Suitable dispersing or suspending agents for aqueous suspensions, include synthetic and natural gums such as tragacanth, acacia, alginate, dextran, sodium carboxymethylcellulose, methylcellulose, polyvinyl-pyrrolidone or gelatin. The liquid forms in suitably flavored suspending or dispersing agents may also include the synthetic and natural gums, for example, tragacanth, acacia, methyl-cellulose and the like. For parenteral administration, sterile suspensions and solutions are desired. Isotonic preparations which generally contain suitable preservatives are employed when intravenous administration is desired.
Advantageously, compounds of Formulae (I) or (II) may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three or four times daily. Furthermore, compounds for the present invention can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermal skin patches well known to those of ordinary skill in that art. To be administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittent throughout the dosage regimen.
For instance, for oral administration in the form of a tablet or capsule, the active drug component can be combined with an oral, non-toxic pharmaceutically acceptable inert carrier such as ethanol, glycerol, water and the like. Moreover, when desired or necessary, suitable binders; lubricants, disintegrating agents and coloring agents can also be incorporated into the mixture. Suitable binders include, without limitation, starch, gelatin, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth or sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride and the like. Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum and the like.
The daily dosage of the products may be varied over a wide range from 1 to 5000 mg per adult human per day. For oral administration, the compositions are preferably provided in the form of tablets containing, 0.01, 0.05, 0.1, 0.5, 1.0, 2.5, 5.0, 10.0, 15.0, 25.0, 50.0, 100, 150, 200, 250 and 500 milligrams of the active ingredient for the symptomatic adjustment of the dosage to the patient to be treated. An effective amount of the drug is ordinarily supplied at a dosage level of from about 0.01 mg/kg to about 200 mg/kg of body weight per day. Particularly, the range is from about 0.03 to about 15 mg/kg of body weight per day, and more particularly, from about 0.05 to about 10 mg/kg of body weight per day. The compounds may be administered on a regimen up to four or more times per day, preferably of 1 to 2 times per day.
Optimal dosages to be administered may be readily determined by those skilled in the art, and will vary with the particular compound used, the mode of administration, the strength of the preparation, the mode of administration, and the advancement of the disease condition. In addition, factors associated with the particular patient being treated, including patient age, weight, diet and time of administration, will result in the need to adjust dosages.
The compound of the present invention can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamellar vesicles, and multilamellar vesicles. Liposomes can be formed from a variety of lipids, including but not limited to amphipathic lipids such as phosphatidylcholines, sphingomyelins, phosphatidylethanolamines, phophatidylcholines, cardiolipins, phosphatidylserines, phosphatidylglycerols, phosphatidic acids, phosphatidylinositols, diacyl trimethylammonium propanes, diacyl dimethylammonium propanes, and stearylamine, neutral lipids such as triglycerides, and combinations thereof. They may either contain cholesterol or may be cholesterol-free.
The compound of the present invention can also be administered locally. Any delivery device, such as intravascular drug delivery catheters, wires, pharmacological stents and endoluminal paving, may be utilized. It is preferred that the delivery device comprises a stent that includes a coating or sheath which elutes or releases the compounds. The delivery system for such a device may comprise a local infusion catheter that delivers the compound at a rate controlled by the administrator.
The present invention provides a drug delivery device comprising an intraluminal medical device, preferably a stent, and a therapeutic dosage of a compound of the invention.
The term “stent” refers to any device capable of being delivered by a catheter. A stent is routinely used to prevent vascular closure due to physical anomalies such as unwanted inward growth of vascular tissue due to surgical trauma. It often has a tubular, expanding lattice-type structure appropriate to be left inside the lumen of a duct to relieve an obstruction. The stent has a lumen wall-contacting surface and a lumen-exposed surface. The lumen-wall contacting surface is the outside surface of the tube and the lumen-exposed surface is the inner surface of the tube. The stent can be polymeric, metallic or polymeric and metallic, and it can optionally be biodegradable.
Commonly, stents are inserted into the lumen in a non-expanded form and are then expanded autonomously, or with the aid of a second device in situ. A typical method of expansion occurs through the use of a catheter-mounted angioplastry balloon which is inflated within the stenosed vessel or body passageway in order to shear and disrupt the obstructions associated with the wall components of the vessel and to obtain an enlarged lumen. Self-expanding stents as described in US 2002/0016625 A1 (Falotico et al., in pending) may also be utilized. The combination of a stent with drugs, agents or compounds which prevent inflammation and proliferation, may provide the most efficacious treatment for post-angioplastry restenosis.
Compounds of the invention can be incorporated into or affixed to the stent in a number of ways and in utilizing any number of biocompatible materials. In one exemplary embodiment, the compound is directly incorporated into a polymeric matrix, such as the polymer polypyrrole, and subsequently coated onto the outer surface of the stent. Essentially, the compound elutes from the matrix by diffusion through the polymer molecules. Stents and methods for coating drugs on stents are discussed in detail in WIPO publication WO9632907. In another exemplary embodiment, the stent is first coated with as a base layer comprising a solution of the compound, ethylene-co-vinylacetate, and polybutylmethacrylate. Then, the stent is further coated with an outer layer comprising only polybutylmethacrylate. The outlayer acts as a diffusion barrier to prevent the compound from eluting too quickly and entering the surrounding tissues. The thickness of the outer layer or topcoat determines the rate at which the compound elutes from the matrix. Stents and methods for coating are discussed in detail in U.S. Publication No. 2002/0016625 and references disclosed therein.
The solution of the compound of the invention and the biocompatible materials/polymers may be incorporated into or onto a stent in a number of ways. For example, the solution may be sprayed onto the stent or the stent may be dipped into the solution. In a preferred embodiment, the solution is sprayed onto the stent and then allowed to dry. In another exemplary embodiment, the solution may be electrically charged to one polarity and the stent electrically changed to the opposite polarity. In this manner, the solution and stent will be attracted to one another. In using this type of spraying process, waste may be reduced and more control over the thickness of the coat may be achieved. Compound is preferably only affixed to the outer surface of the stent which makes contact with one tissue. However, for some compounds, the entire stent may be coated. The combination of the dose of compound applied to the stent and the polymer coating that controls the release of the drug is important in the effectiveness of the drug. The compound preferably remains on the stent for at least three days up to approximately six months and more, preferably between seven and thirty days.
Any number of non-erodible biocompatible polymers may be utilized in conjunction with the compound of the invention. It is important to note that different polymers may be utilized for different stents. For example, the above-described ethylene-co-vinylacetate and polybutylmethacrylate matrix works well with stainless steel stents. Other polymers may be utilized more effectively with stents formed from other materials, including materials that exhibit superelastic properties such as alloys of nickel and titanium.
The present invention further provides a method for the treatment of disorders related to PDGF-R, particularly restenosis, intimal hyperplasia or inflammation, in blood vessel walls, which comprises the controlled delivery, by release from an intraluminal medical device, such as a stent, of a compound of the invention in therapeutic effective amounts.
Methods for introducing a stent into a lumen of a body are well known and the compound-coated stents of this invention are preferably introduced using a catheter. As will be appreciated by those of ordinary skill in the art, methods will vary slightly based on the location of stent implantation. For coronary stent implantation, the balloon catheter bearing the stent is inserted into the coronary artery and the stent is positioned at the desired site. The balloon is inflated, expanding the stent. As the stent expands, the stent contacts the lumen wall. Once the stent is positioned, the balloon is deflated and removed. The stent remains in place with the lumen-contacting surface bearing the compound directly contacting the lumen wall surface. Stent implantation may be accompanied by anticoagulation therapy as needed.
Optimum conditions for delivery of the compounds for use in the stent of the invention may vary with the different local delivery systems used, as well as the properties and concentrations of the compounds used. Conditions that may be optimized include, for example, the concentrations of the compounds, the delivery volume, the delivery rate, the depth of penetration of the vessel wall, the proximal inflation pressure, the amount and size of perforations and the fit of the drug delivery catheter balloon. Conditions may be optimized for inhibition of smooth muscle cell proliferation at the site of injury such that significant arterial blockage due to restenosis does not occur, as measured, for example, by the proliferative ability of the smooth muscle cells, or by changes in the vascular resistance or lumen diameter. Optimum conditions can be determined based on data from animal model studies using routine computational methods.
Another alternative method for administering compounds of this invention may be by conjugating the compound to a targeting agent which directs the conjugate to its intended site of action, i.e., to vascular endothelial cells, or to tumor cells. Both antibody and non-antibody targeting agents may be used. Because of the specific interaction between the targeting agent and its corresponding binding partner, a compound of this invention can be administered with high local concentrations at or near a target site and thus treats the disorder at the target site more effectively.
The antibody targeting agents include antibodies or antigen-binding fragments thereof, that bind to a targetable or accessible component of a tumor cell, tumor vasculature, or tumor stroma. The “targetable or accessible component” of a tumor cell, tumor vasculature or tumor stroma, is preferably a surface-expressed, surface-accessible or surface-localized component. The antibody targeting agents also include antibodies or antigen-binding fragments thereof, that bind to an intracellular component that is released from a necrotic tumor cell. Preferably such antibodies are monoclonal antibodies, or antigen-binding fragments thereof, that bind to insoluble intracellular antigen(s) present in cells that may be induced to be permeable, or in cell ghosts of substantially all neoplastic and normal cells, but are not present or accessible on the exterior of normal living cells of a mammal.
As used herein, the term “antibody” is intended to refer broadly to any immunologic binding agent such as IgG, IgM, IgA, IgE, F(ab′)2, a univalent fragment such as Fab′, Fab, Dab, as well as engineered antibodies such as recombinant antibodies, humanized antibodies, bispecific antibodies, and the like.
The antibody can be either the polyclonal or the monoclonal, although the monoclonal is preferred. There is a very broad array of antibodies known in the art that have immunological specificity for the cell surface of virtually any solid tumor type (see a Summary Table on monoclonal antibodies for solid tumors in U.S. Pat. No. 5,855,866 to Thorpe et al). Methods are known to those skilled in the art to produce and isolate antibodies against tumor (see i.e., U.S. Pat. No. 5,855,866 to Thorpe et al., and U.S. Pat. No. 6,342,219 to Thorpe et al.).
The non-antibody targeting agents includes growth factors, such as PDGF, VEGF and FGF; peptides containing the tripeptide R-G-D, that bind specifically to the tumor vasculature; and other targeting components such as annexins and related ligands. In addition, a variety of other organic molecules can also be used as targeting agents for tumors, examples are hyaluronan oligosaccharides which specifically recognize Hyaluronan-binding protein, a cell surface protein expressed during tumor cell and endothelial cell migration and during capillary-like tubule formation (U.S. Pat. No. 5,902,795, Toole et al.), and polyanionic compounds, particularly polysulphated or polysulphonated compounds such as N— and O— sulfated polyanionic polysaccharides, polystyrene sulfonate and other polyanionic compounds described in U.S. Pat. No. 5,762,918 (Thorpe), which selectively bind to vascular endothelial cells.
Techniques for conjugating therapeutic moiety to antibodies are well known, see, e.g., Amon et al., “Monoclonal Antibodies For Immunotargeting Of Drugs In Cancer Therapy”, in Monoclonal Antibodies And Cancer Therapy, Reisfeld et al. (eds.), pp. 243-56 (Alan R. Liss, Inc. 1985); Hellstrom et al., “Antibodies For Drug Delivery”, in Controlled Drug Delivery (2nd Ed.), Robinson et al. (eds.), pp. 623-53 (Marcel Dekker, Inc. 1987); Thorpe, “Antibody Carriers Of Cytotoxic Agents In Cancer Therapy: A Review”, in Monoclonal Antibodies 84: Biological And Clinical Applications, Pinchera et al. (eds.), pp. 475-506 (1985). Similar techniques can also be applied to attach compounds of the invention to non-antibody targeting agents. Those skilled in the art will know, or be able to determine, methods of forming conjugates with non-antibody targeting agents, such as small molecules, oligopeptides, polysaccharides, or other polyanionic compounds.
Although any linking moiety that is reasonably stable in blood, can be used to link the compound of the invention to the targeting agent, biologically-releasable bonds and/or selectively cleavable spacers or linkers is preferred. “Biologically-releasable bonds” and “selectively cleavable spacers or linkers” still have reasonable stability in the circulation, but are releasable, cleavable or hydrolyzable only or preferentially under certain conditions, i.e., within a certain environment, or in contact with a particular agent. Such bonds include, for example, disulfide and trisulfide bonds and acid-labile bonds, as described in U.S. Pat. Nos. 5,474,765 and 5,762,918 and enzyme-sensitive bonds, including peptide bonds, esters, amides, phosphodiesters and glycosides as described in U.S. Pat. Nos. 5,474,765 and 5,762,918. Such selective-release design features facilitate sustained release of the compounds from the conjugates at the intended target site.
The present invention provides a pharmaceutical composition that comprises an effective amount of the compound of the invention conjugated to a targeting agent and a pharmaceutically acceptable carrier described supra.
The present invention further provides a method of treating of a disorder related to PDGF-R, particularly a tumor, which comprises administering to the subject a therapeutic effective amount of compound of Formulae (I) or (II) conjugated to a targeting agent. When proteins such as antibodies or growth factors, or polysaccharides are used as targeting agents, they are preferably administered in the form of injectable compositions. The injectable antibody solution will be administered into a vein, artery or into the spinal fluid over the course of from 2 minutes to about 45 minutes, preferably from 10 to 20 minutes. In certain cases, intradermal and intracavitary administration are advantageous for tumors restricted to areas close to particular regions of the skin and/or to particular body cavities. In addition, intrathecal administrations may be used for tumors located in the brain.
Therapeutically effective doses of the compound of the invention conjugated to a targeting agent depend on the individual, the disease type, the disease state, the method of administration and other clinical variables. The effective dosages are readily determinable using data from an animal model. Experimental animals bearing solid tumors are frequently used to optimize appropriate therapeutic doses prior to translating to a clinical environment. Such models are known to be very reliable in predicting effective anti-cancer strategies. For example, mice bearing solid tumors, are widely used in pre-clinical testing to determine working ranges of therapeutic agents that give beneficial anti-tumor effects with minimal toxicity.
One skilled in the art will recognize that the compounds of Formulae (I) or (II) may have one or more asymmetric carbon atoms in their structure. It is intended that the present invention includes within its scope the stereochemically pure isomeric forms of the compounds as well as their racemates. Stereochemically pure isomeric forms may be obtained by the application of art known principles. Diastereoisomers may be separated by physical separation methods such as fractional crystallization and chromatographic techniques, and enantiomers may be separated from each other by the selective crystallization of the diastereomeric salts with optically active acids or bases or by chiral chromatography. Pure stereoisomers may also be prepared synthetically from appropriate stereochemically pure starting materials, or by using stereoselective reactions.
Some of the compounds of the present invention may have trans and cis isomers. In addition, where the processes for the preparation of the compounds according to the invention give rise to mixture of stereoisomers, these isomers may be separated by conventional techniques such as preparative chromatography. The compounds may be prepared as a single stereoisomer or in racemic form as a mixture of some possible stereoisomers. The non-racemic forms may be obtained by either synthesis or resolution. The compounds may, for example, be resolved into their component enantiomers by standard techniques, such as the formation of diastereomeric pairs by salt formation. The compounds may also be resolved by covalent linkage to a chiral auxiliary, followed by chromatographic separation and/or crystallographic separation, and removal of the chiral auxiliary. Alternatively, the compounds may be resolved using chiral chromatography. The scope of the present invention is intended to cover all such isomers or stereoisomers per se, as well as mixtures of cis and trans isomers, mixtures of diastereomers and racemic mixtures of enantiomers (optical isomers) as well.
While the foregoing specification teaches the principles of the present invention, with examples provided for the purpose of illustration, it will be understood that the practice of the invention encompasses all of the usual variations, adaptations and/or modifications as come within the scope of the following claims and their equivalents.
