TECHNICAL FIELD
The present invention relates to compounds which are useful for inhibiting protein tyrosine kinases, methods of making the compounds, compositions containing the compounds, and methods of treatment using the compounds.
BACKGROUND OF THE INVENTION
Protein tyrosine kinases (PTKs) are enzymes which catalyse the phosphorylation of specific tyrosine residues in cellular proteins. This post-translational modification of these substrate proteins, often enzymes themselves, acts as a molecular switch regulating cell proliferation, activation, or differentiation. Aberrant or excessive PTK activity has been observed in many disease states including benign and malignant proliferative disorders as well as diseases resulting from inappropriate activation of the immune system (e.g., autoimmune disorders), allograft rejection, and graft vs. host disease. In addition, endothelial-cell specific receptor PTKs such as KDR and Tie-2 mediate the angiogenic process, and are thus involved in supporting the progression of cancers and other diseases involving inappropriate vascularization (e.g., diabetic retinopathy, choroidal neovascularization due to age-related macular degeneration, psoriasis, arthritis, retinopathy of prematurity, and infantile hemangiomas).
The identification of effective small compounds which specifically inhibit signal transduction and cellular proliferation by modulating the activity of tyrosine kinases to regulate and modulate abnormal or inappropriate cell proliferation, differentiation, or metabolism is therefore desirable. In particular, the identification of methods and compounds that specifically inhibit the function of a tyrosine kinase which is essential for angiogenic processes or the formation of vascular hyperpermeability leading to edema, ascites, effusions, exudates, and macromolecular extravasation and matrix deposition as well as associated disorders would be beneficial.

In accordance with methods of treatment and pharmaceutical compositions of the invention, the compounds can be administered alone or in combination with other anticancer agents. When using the compounds, the specific therapeutically effective dose level for any particular patient will depend upon factors such as the disorder being treated and the severity of the disorder; the activity of the particular compound used; the specific composition employed; the age, body weight, general health, sex, and diet of the patient; the time of administration; the route of administration; the rate of excretion of the compound employed; the duration of treatment; and drugs used in combination with or coincidently with the compound used. The compounds can be administered orally, parenterally, osmotically (nasal sprays), rectally, vaginally, or topically in unit dosage formulations containing carriers, adjuvants, diluents, vehicles, or combinations thereof. The term “parenteral” includes infusion as well as subcutaneous, intravenous, intramuscular, and intrasternal injection.
Parenterally administered aqueous or oleaginous suspensions of the compounds can be formulated with dispersing, wetting, or suspending agents. The injectable preparation can also be an injectable solution or suspension in a diluent or solvent. Among the acceptable diluents or solvents employed are water, saline, Ringer's solution, buffers, monoglycerides, diglycerides, fatty acids such as oleic acid, and fixed oils such as monoglycerides or diglycerides.
The inhibitory effect of parenterally administered compounds can be prolonged by slowing their absorption. One way to slow the absorption of a particular compound is administering injectable depot forms comprising suspensions of crystalline, amorphous, or otherwise water-insoluble forms of the compound. The rate of absorption of the compound is dependent on its rate of dissolution which is, in turn, dependent on its physical state. Another way to slow absorption of a particular compound is administering injectable depot forms comprising the compound as an oleaginous solution or suspension. Yet another way to slow absorption of a particular compound is administering injectable depot forms comprising microcapsule matrices of the compound trapped within liposomes, microemulsions, or biodegradable polymers such as polylactide-polyglycolide, polyorthoesters or polyanhydrides. Depending on the ratio of drug to polymer and the composition of the polymer, the rate of drug release can be controlled.
Transdermal patches can also provide controlled delivery of the compounds. The rate of absorption can be slowed by using rate controlling membranes or by trapping the compound within a polymer matrix or gel. Conversely, absorption enhancers can be used to increase absorption.
Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In these solid dosage forms, the active compound can optionally comprise diluents such as sucrose, lactose, starch, talc, silicic acid, aluminum hydroxide, calcium silicates, polyamide powder, tableting lubricants, and tableting aids such as magnesium stearate or microcrystalline cellulose. Capsules, tablets and pills can also comprise buffering agents, and tablets and pills can be prepared with enteric coatings or other release-controlling coatings. Powders and sprays can also contain excipients such as talc, silicic acid, aluminum hydroxide, calcium silicate, polyamide powder, or mixtures thereof. Sprays can additionally contain customary propellants such as chlorofluorohydrocarbons or substitutes therefore.
Liquid dosage forms for oral administration include emulsions, microemulsions, solutions, suspensions, syrups, and elixirs comprising inert diluents such as water. These compositions can also comprise adjuvants such as wetting, emulsifying, suspending, sweetening, flavoring, and perfuming agents.
Topical dosage forms include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants, and transdermal patches. The compound is mixed under sterile conditions with a carrier and any needed preservatives or buffers.

KDR Tyrosine Kinase Production Using Baculovirus System:
The coding sequence for the human KDR intra-cellular domain (aa789-1354) was generated through PCR using cDNAs isolated from HUVEC cells. A poly-His6 sequence was introduced at the N-terminus of this protein as well. This fragment was cloned into transfection vector pVL1393 at the Xba 1 and Not 1 site. Recombinant baculovirus (BV) was generated through co-transfection using the BaculoGold Transfection reagent (PharMingen). Recombinant BV was plaque purified and verified through Western analysis. For protein production, SF-9 cells were grown in SF-900-II medium at 2×106/mL, and were infected at 0.5 plaque forming units per cell (MOI). Cells were harvested at 48 hours post infection.
Purification of KDR
SF-9 cells expressing (His)6KDR(aa789-1354) were lysed by adding 50 mL of Triton X-100 lysis buffer (20 mM Tris, pH 8.0, 137 mM NaCl, 10% glycerol, 1% Triton X-100, 1 mM PMSF, 10 μg/mL aprotinin, 1 μg/mL leupeptin) to the cell pellet from 1 L of cell culture. The lysate was centrifuged at 19,000 rpm in a Sorval SS-34 rotor for 30 minutes at 4° C. The cell lysate was applied to a 5 mL NiCl2 chelating sepharose column, equilibrated with 50 mM HEPES, pH7.5, 0.3M NaCl. KDR was eluted using the same buffer containing 0.25M imidazole. Column fractions were analyzed using SDS-PAGE and an ELISA assay (below) which measures kinase activity. The purified KDR was exchanged into 25 mM HEPES, pH7.5, 25 mM NaCl, 5 mM DTT buffer and stored at −80° C.
Compounds of the present invention inhibited KDR at IC50's between about 0.003 μM and >50 μM. Preferred compounds inhibited KDR at IC50's between about 0.003 μM and about 0.5 μM.
Human Tie-2 Kinase Production and Purification
The coding sequence for the human Tie-2 intra-cellular domain (aa775-1124) was generated through PCR using cDNAs isolated from human placenta as a template. A poly-His6 sequence was introduced at the N-terminus and this construct was cloned into transfection vector pVL 1939 at the Xba 1 and Not 1 site. Recombinant BV was generated through co-transfection using the BaculoGold Transfection reagent (PharMingen). Recombinant BV was plaque purified and verified through Western analysis. For protein production, SF-9 insect cells were grown in SF-900-II medium at 2×106/mL, and were infected at MOI of 0.5. Purification of the His-tagged kinase used in screening was analogous to that described for KDR.
Compounds of the present invention inhibited Tie-2 at IC50's between about 0.01 μM and >50 μM. Preferred compounds inhibited Tie-2 at IC50's between about 0.01 μM and 0.5 μM.
Human Flt-1 Tyrosine Kinase Production and Purification
The baculoviral expression vector pVL1393 (Phar Mingen, Los Angeles, Calif.) was used. A nucleotide sequence encoding poly-His6 was placed 5′ to the nucleotide region encoding the entire intracellular kinase domain of human Flt-1 (amino acids 786-1338). The nucleotide sequence encoding the kinase domain was generated through PCR using cDNA libraries isolated from HUVEC cells. The histidine residues enabled affinity purification of the protein as a manner analogous to that for KDR and ZAP70. SF-9 insect cells were infected at a 0.5 multiplicity and harvested 48 hours post infection.
EGFR Tyrosine Kinase Source
EGFR was purchased from Sigma (Cat #E-3641; 500 units/50 μl) and the EGF ligand was acquired from Oncogene Research Products/Calbiochem (Cat #PFO11-100).
Expression of ZAP70
The baculoviral expression vector used was pVL1393. (Pharmingen, Los Angeles, Calif.) The nucleotide sequence encoding amino acids M(H)6 LVPR9S was placed 5′ to the region encoding the entirety of ZAP70 (amino acids 1-619). The nucleotide sequence encoding the ZAP70 coding region was generated through PCR using cDNA libraries isolated from Jurkat immortalized T-cells. The histidine residues enabled affinity purification of the protein (vide infra). The LVPR9S bridge constitutes a recognition sequence for proteolytic cleavage by thrombin, enabling removal of the affinity tag from the enzyme. SF-9 insect cells were infected at a multiplicity of infection of 0.5 and harvested 48 hours post infection.
Extraction and Purification of ZAP70
SF-9 cells were lysed in a buffer consisting of 20 mM Tris, pH 8.0, 137 mM NaCl, 10% glycerol, 1% Triton X-100, 1 mM PMSF, 1 μg/mL leupeptin, 10 μg/mL aprotinin and 1 mM sodium orthovanadate. The soluble lysate was applied to a chelating sepharose HiTrap column (Pharmacia) equilibrated in 50 mM HEPES, pH 7.5, 0.3M NaCl. Fusion protein was eluted with 250 mM imidazole. The enzyme was stored in buffer containing 50 mM HEPES, pH 7.5, 50 mM NaCl and 5 mM DTT.

Enzyme linked immunosorbent assays (ELISA) were used to detect and measure the presence of tyrosine kinase activity. The ELISA were conducted according to known protocols which are described in, for example, Voller, et al., 1980, “Enzyme-Linked Immunosorbent Assay,” In: Manual of Clinical Immunology, 2d ed., edited by Rose and Friedman, pp 359-371 Am. Soc. of Microbiology, Washington, D.C.

VEGF-Induced KDR Phosphorylation in Human Umbilical Vein Endothelial Cells (HUVEC) as Measured by Western Blots:
1. HUVEC cells (from pooled donors) can be purchased from Clonetics (San Diego, Calif.) and cultured according to the manufacturer directions. Only early passages (3-8) are used for this assay. Cells are cultured in 100 mm dishes (Falcon for tissue culture; Becton Dickinson; Plymouth, England) using complete EBM media (Clonetics).
2. For evaluating a compound's inhibitory activity, cells are trypsinized and seeded at 0.5-1.0×105 cells/well in each well of 6-well cluster plates (Costar; Cambridge, Mass.).
3. 3-4 days after seeding, plates are typically 90-100% confluent. Medium is removed from all the wells, cells are rinsed with 5-10 mL of PBS and incubated 18-24 h with 5 mL of EBM base media with no supplements added (i.e., serum starvation).
4. Serial dilutions of inhibitors are added in 1 mL of EBM media (25 μM, 5 μM, or 1 μM final concentration to cells and incubated for one hour at 37° C. Human recombinant VEGF165 (R & D Systems) is then added to all the wells in 2 mL of EBM medium at a final concentration of 50 ng/mL and incubated at 37° C. for 10 minutes. Control cells untreated or treated with VEGF only are used to assess background phosphorylation and phosphorylation induction by VEGF.
All wells are then rinsed with 5-10 mL of cold PBS containing 1 mM Sodium Orthovanadate (Sigma) and cells are lysed and scraped in 200 μL of RIPA buffer (50 mM Tris-HCl) pH 7, 150 mM NaCl, 1% NP-40, 0.25% sodium deoxycholate, 1 mM EDTA) containing protease inhibitors (PMSF 1 mM, aprotinin 1 μg/mL, pepstatin 1 μg/mL, leupeptin 1 μg/mL, Na vanadate 1 mM, Na fluoride 1 mM) and 1 μg/mL of Dnase (all chemicals from Sigma Chemical Company, St. Louis, Mo.). The lysate is spun at 14,000 rpm for 30 minutes, to eliminate nuclei.
Equal amounts of proteins are then precipitated by addition of cold (−20° C.) ethanol (2 volumes) for a minimum of 1 hour or a maximum of overnight. Pellets are reconstituted in LaemLi sample buffer containing 5%-mercaptoethanol (BioRad; Hercules, Calif.) and boiled for 5 minutes. The proteins are resolved by polyacrylamide gel electrophoresis (6%, 1.5 mm Novex, San Deigo, Calif.) and transferred onto a nitrocellulose membrane using the Novex system. After blocking with bovine serum albumin (3%), the proteins are probed overnight with anti-KDR polyclonal antibody (C20, Santa Cruz Biotechnology; Santa Cruz, Calif.) or with anti-phosphotyrosine monoclonal antibody (4G10, Upstate Biotechnology, Lake Placid, N.Y.) at 4° C. After washing and incubating for 1 hour with HRP-conjugated F(ab)2 of goat anti-rabbit or goat-anti-mouse IgG the bands are visualized using the emission chemiluminescence (ECL) system (Amersham Life Sciences, Arlington Heights, Ill.).
In vivo Uterine Edema Model
This assay measures the capacity of compounds to inhibit the acute increase in uterine weight in mice which occurs in the first few hours following estrogen stimulation. This early onset of uterine weight increase is known to be due to edema caused by increased permeability of uterine vasculature. Cullinan-Bove and Koss (Endocrinology (1993), 133:829-837) demonstrated a close temporal relationship of estrogen-stimulated uterine edema with increased expression of VEGF mRNA in the uterus. These results have been confirmed by the use of neutralizing monoclonal antibody to VEGF which significantly reduced the acute increase in uterine weight following estrogen stimulation (WO 97/42187). Hence, this system can serve as a model for in vivo inhibition of VEGF signalling and the associated hyperpermeability and edema.
Materials:
All hormones can be purchased from Sigma (St. Louis, Mo.) or Cal Biochem (La Jolla, Calif.) as lyophilized powders and prepared according to supplier instructions. Vehicle components (DMSO, Cremaphor EL) can be purchased from Sigma (St. Louis, Mo.). Mice (Balb/c, 8-12 weeks old) can be purchased from Taconic (Germantown, N.Y.) and housed in a pathogen-free animal facility in accordance with institutional Animal Care and Use Committee Guidelines.
Method:
Day 1: Balb/c mice are given an intraperitoneal (i.p.) injection of 12.5 units of pregnant mare's serum gonadotropin (PMSG).
Day 3: Mice receive 15 units of human chorionic gonadotropin (hCG) i.p.
Day 4: Mice are randomized and divided into groups of 5-10. Test compounds are administered by i.p., i.v. or p.o. routes depending on solubility and vehicle at doses ranging from 1-100 mg/kg. Vehicle control group receive vehicle only and two groups are left untreated.
Thirty minutes later, experimental, vehicle and 1 of the untreated groups are given an i.p. injection of 17-estradiol (500 mg/kg). After 2-3 hours, the animals are sacrificed by CO2 inhalation. Following a midline incision, each uterus was isolated and removed by cutting just below the cervix and at the junctions of the uterus and oviducts. Fat and connective tissue were removed with care not to disturb the integrity of the uterus prior to weighing (wet weight). Uteri are blotted to remove fluid by pressing between two sheets of filter paper with a one liter glass bottle filled with water. Uteri are weighed following blotting (blotted weight). The difference between wet and blotted weights is taken as the fluid content of the uterus. Mean fluid content of treated groups is compared to untreated or vehicle treated groups. Significance is determined by Student's test. Non-stimulated control group is used to monitor estradiol response.
Certain compounds of this invention which are inhibitors of angiogenic receptor tyrosine kinases can also be shown active in a Matrigel implant model of neovascularization. The Matrigel neovascularization model involves the formation of new blood vessels within a clear marble of extracellular matrix implanted subcutaneously which is induced by the presence of proangiogenic factor producing tumor cells (for examples see: Passaniti, A., et al., Lab. Investig. (1992), 67(4), 519-528; Anat. Rec. (1997), 249(1), 63-73; Int. J. Cancer (1995), 63(5), 694-701; Vasc. Biol. (1995), 15(11), 1857-6). The model preferably runs over 3-4 days and endpoints include macroscopic visual/image scoring of neovascularization, microscopic microvessel density determinations, and hemoglobin quantitation (Drabkin method) following removal of the implant versus controls from animals untreated with, inhibitors. The model may alternatively employ bFGF or HGF as the stimulus.
The compounds of the present invention may be used in the treatment of protein kinase-mediated conditions, such as benign and neoplastic proliferative diseases and disorders of the immune system. Such diseases include autoimmune diseases, such as rheumatoid arthritis, thyroiditis, type 1 diabetes, multiple sclerosis, sarcoidosis, inflammatory bowel disease, Crohn's disease, myasthenia gravis and systemic lupus erythematosus; psoriasis, organ transplant rejection (e.g., kidney rejection, graft versus host disease), benign and neoplastic proliferative diseases, human cancers such as lung, breast, stomach, bladder, colon, pancreatic, ovarian, prostate and rectal cancer and hematopoietic malignancies (leukemia and lymphoma), glioblastoma, infantile hemangioma, and diseases involving inappropriate vascularization (for example diabetic retinopathy, retinopathy of prematurity, choroidal neovascularization due to age-related macular degeneration, and infantile hemangiomas in human beings). Such inhibitors may be useful in the treatment of disorders involving VEGF mediated edema, ascites, effusions, and exudates, including for example macular edema, cerebral edema, acute lung injury and adult respiratory distress syndrome (ARDS). In addition, the compounds of the invention may be useful in the treatment of pulmonary hypertension, particularly in patients with thromboembolic disease (J. Thorac. Cardiovasc. Surg. 2001, 122 (1), 65-73).
Compounds of the invention may have therapeutic utility in the treatment of diseases involving both identified, including those not mentioned herein, and as yet unidentified protein tyrosine kinases. Preferred compounds of the invention are compounds which have shown the ability to inhibit multiple kinases and may not necessarily be the most potent inhibitors of any one particular kinase.
