FIELD OF THE INVENTION
The invention concerns compounds which inhibit MEK and which have activity as anti-neoplastic agents. These compounds include N-substituted-3-hydroxy-5-aryl-isothiazole-4-carboxamidines. Also included are the tautomeric isothiazol-3(2H)-ones.
BACKGROUND OF THE INVENTION
Oncogenes—genes that contribute to the production of cancers—are generally mutated forms of certain normal cellular genes (“proto-oncogenes”). Oncogenes often encode abnormal versions of signal pathway components, such as receptor tyrosine kinases, serine-threonine kinases, or downstream signaling molecules. The central downstream signaling molecules are the Ras proteins, which are anchored on the inner surfaces of cytoplasmic membranes, and which hydrolyze bound guanosine triphosphate (GTP) to guanosine diphosphate (GDP). When activated by a growth factor, growth factor receptors initiate a chain of reactions that leads to the activation of guanine nucleotide exchange activity on Ras. Ras alternates between an active “on” state with a bound GTP (hereafter “Ras.GTP”) and an inactive “off” state with a bound GDP. The active “on” state, Ras.GTP, binds to and activates proteins that control the growth and differentiation of cells.
For example, in the “mitogen-activated protein kinase (MAP kinase) cascade,” Ras.GTP leads to the activation of a cascade of serine/threonine kinases. One of several groups of kinases known to require a Ras.GTP for their own activation is the Raf family. The Raf proteins activate “MEK1” and “MEK2,” abbreviations for mitogen-activated ERK-activating kinases (where ERK is extracellular signal-regulated protein kinase, another designation for MAPK). MEK1 and MEK2 are dual-function serine/threonine and tyrosine protein kinases and are also known as MAP kinase kinases. Thus, Ras.GTP activates Raf, which activates MEK1 and MEK2, which activate MAP kinase (MAPK). Activation of MAP kinase by mitogens appears to be essential for proliferation, and constitutive activation of this kinase is sufficient to induce cellular transformation. Blockade of downstream Ras signaling, as by use of a dominant negative Raf-1 protein, can completely inhibit mitogenesis, whether induced from cell surface receptors or from oncogenic Ras mutants.
The interaction of Raf and Ras is a key regulatory step in the control of cell proliferation. To date, no substrates of MEK other than MAPK have been identified; however, recent reports indicate that MEK may also be activated by other upstream signal proteins such as MEK kinase or MEKK1 and PKC. Activated MAPK translocates and accumulates in the nucleus, where it can phosphorylate and activate transcription factors such as Elk-1 and Sap1a, leading to the enhanced expression of genes such as that for c-fos.
Once activated, Raf and other kinases phosphorylate MEK on two neighboring serine residues, S218 and S222 in the case of MEK-1. These phosphorylations are required for activation of MEK as a kinase. In turn, MEK phosphorylates MAP kinase on two residues separated by a single amino acid: a tyrosine, Y185, and a threonine, T183. MEK appears to associate strongly with MAP kinase prior to phosphorylating it, suggesting that phosphorylation of MAP kinase by MEK may require a prior strong interaction between the two proteins. Two factors—MEK's unusual specificity and its requirement for a strong interaction with MAP kinase prior to phosphorylation—suggest that MEK's mechanism of action may differ sufficiently from the mechanisms of other protein kinases as to allow for selective inhibitors of MEK. Possibly, such inhibitors would operate through allosteric mechanisms rather than through the more usual mechanism involving blockage of an ATP binding site.
MEK1 and MEK2 are, therefore, validated and accepted targets for anti-proliferative therapies, even when the oncogenic mutation does not affect MEK structure or expression. See, e.g., U.S. Patent Publications 2003/0149015 by Barrett et al. and 2004/0029898 by Boyle et al.
An N-unsubstituted, 3-hydroxy-5-phenyoxyphenyl-isothiazole-4-carboxyamidine having anti MEK activity was described in a patent publication commonly assigned with the present application. US 2004/0039037 (Feb. 26, 2004). No analogs or derivatives of the compound were described. A group of 3-phenyloxy-5-alkylureido-isothiazole-4-carboxamide kinase inhibitors having anti-proliferative activity was reported in U.S. Pat. No. 6,548,526 and No. 6,235,764. These compounds were not noted to be MEK inhibitors; they inhibited a tyrosine kinase activity associated with the vascular endothelial growth factor receptor (VEGF).
A second group of isothiazole-4-carboxamides with anti-proliferative activity via blockage of Trk tyrosine kinase—not a VEGF-associated kinase—was described in U.S. Patent Publication 2004/0152691. The compounds are 3-arylsulfanyl-5-heteroarylamino-isothiazoles.
Isoxazole inhibitors of MEK-activated kinase (ERK or MAPK) were described in U.S. Pat. No. 6,649,640 and No. 6,495,582. Rather than 3-hydroxy-4-carboxamides or 3-hydroxy-4-carboxamidines, the compounds disclosed in these patents are 3-unsubstituted or 3-amino substituted-4-aryl isoxazoles.

EXPERIMENTAL DETAILS
Synthesis
Compounds of this invention are prepared according to the schemes below.
I. Synthesis of Contemplated Compounds
The choice of synthetic strategy is not critical to the practice of this invention. Suitable approaches include both those in which commercially available or previously synthesized isothiazoles are modified and those involving cyclization of a thiocarbamoyl acetamide to form the isothiazole ring system.
Scheme 1 illustrates a reaction of 2-cyanoacetamide with an isothiocyanate to an intermediate, and subsequent ring closure by oxidation followed by amination by heating the cyano compound with an amine (e.g., isopropylamine, 2-amino-propan-1-ol) to provide the amidine 4. This general strategy can be used for compounds of formulas II-VI.
More specifically, in step 1 of Scheme 1,2-cyanoacetamide was treated with a strong base (e.g., KOH) and then with a substituted phenyl isothiocyanate 1 in N,N-dimethylformamide (DMF) at a temperature ranging from about −10° C. to 60° C., preferably about 25° C., for a period of about 8 to 24 hours, preferably about 16 hours, to produce compound 2. Then, in step 2 of Scheme 1, compound 2 (in the same reaction vessel as step 1) was treated at about 0° C. with aqueous chloramine solution for about 12 hours, and compound 3 was isolated.
Alternatively, the reaction mixture of step 1 was concentrated and diluted with water, followed by acidification with aqueous hydrochloric acid solution. Filtration and washing with water afforded compound 2. In an organic solvent, preferably ethyl acetate, compound 2 was treated with bromine to provide isothiazole 3. In step 3 of Scheme 1, compound 3 was agitated with an alkylamine (including a hydroxyalkylamine) in ethanol, in a sealed reaction vessel at about 80-120° C., preferably about 100° C., for about 16 to 24 hours, preferably 18 hours, to provide amidine 4 in good yield after chromatography.




Scheme 1 includes the synthesis of compounds wherein R1 is a phenoxy or phenylthio group. In a variation of Scheme 1, a pyridyl, naphthyl, or quinolyl isothiocyanate may be used in place of the phenyl isothiocyanate that is illustrated. Compounds in which R1 is a benzyl, benzoyl, phenylazido, or phenylacetyl group are prepared using commercially available precursors such as p-nitro benzophenone, p-nitro diphenylmethane, and p-nitro diphenylazide. In a variation of Scheme 1, a pyridyl, naphthyl, or quinolyl isothiocyanate may be used in place of the phenyl isothiocyanate that is illustrated.
Preparation of Isothiazoles Using 4-substituted Anilines
The p-phenoxy phenylisothiocyanates can be synthesized by condensing the appropriately substituted p-fluoronitrobenzene with a phenol or aniline, as shown below.




General Procedure for 4-substituted Phenols and Anilines




Preparation of Isothiocyanates from Anilines
A mixture comprising a 4-fluoronitrobenzene 6 (0.02 mol), a suitable aniline or phenol 7 (0.022 mol), and potassium carbonate (0.022 mol) in 40 ml of anhydrous DMF was heated overnight at 150° C. with stirring. After cooling to room temperature, the reaction mixture was poured into 500 ml of ice water and stirred for 30 min. The precipitate was collected by filtration, washed with water, and dried in vacuo to give a 4-substituted nitrobenzene 8. The nitrobenzene 8 was dissolved in 100-200 ml of ethanol and stirred for 5-6 hours under hydrogen in the presence of catalyst 10% Pd—C (50-100 mg), at atmospheric pressure and ambient temperature. The catalyst was removed by filtration, and the filtrate was concentrated to dryness to give the crude substituted aniline 9, which was used for the next step without further purification.
Method 1: The appropriate aniline 10 (30 mmol) was added to a biphasic mixture of CHCl3 and saturated aqueous NaHCO3 (1:1, v/v, 247 ml), followed by dropwise addition at room temperature, with stirring, of a solution of thiophosgene (30 mmol) in dichloromethane (20 ml). The mixture was stirred vigorously at room temperature for 1 hour. The bottom layer of the mixture was separated, and the aqueous layer was extracted twice with CHCl3. The combined organic solution was washed with water, dried over MgSO4, and evaporated to give isocyanate 11 as a yellow solid, which was used for the next step without further purification.
Method 2: To a solution of aniline (30 mmol) and DBU (60 mmol) in 60 ml of anhydrous dichloromethane, a solution of thiophosgene (30 mmol) in 20 ml of dry dichloromethane was added dropwise with stirring at room temperature over 30 minutes. The reaction mixture was diluted with 200 ml of chloroform and washed with 1N HCl solution (300 ml×2) and water (300 ml) respectively. The chloroform solution was dried over anhydrous sodium sulfate, and the solvent was evaporated in vacuo. The residue was purified by silica gel column to give pure isothiocyanates.
(3) Preparation of Isothiazoles (see Scheme 1)
3-Hydroxy-5-phenylamino-isothiazol-4-carbonitrile
Method 1: To a cooled suspension of finely ground potassium hydroxide (0.337 g, 6 mmol) in DMF (8 ml) was added cyanoacetamide (0.505 g, 6 mmol) followed by addition of 4-methoxyphenyl isothiocyanate (0.83 ml, 6 mmol). The reaction mixture was stirred at room temperature for 24 hours and treated with aqueous chloramine (30 ml) at 0° C. The mixture was further stirred at room temperature for 12 hours, and evaporated to give a residue, which was partitioned between water and ethyl acetate. The aqueous layer was washed twice with ethyl acetate, then cooled to 0° C. and acidified with 1N HCl solution to about pH-3. The precipitate was filtered and washed with water and dried in vacuo to afford a yellow powder (0.95 g, 73%).
Method 2: Condensation of isothiocyanate with 2-cyanoacetamide: Procedure 1: To a cooled suspension of finely ground potassium hydroxide (0.337 g, 6 mmol) in DMF (8 ml) was added cyanoacetamide (0.505 g, 6 mmol), followed by addition of 4-methoxyphenyl isothiocyanate (0.83 ml, 6 mmol). The reaction mixture was stirred at room temperature for 16 hours and concentrated to give a syrup, which was diluted with water and acidified with 1 N aqueous HCl solution. The suspension was filtered, and the solid was washed with water and dried in vacuo. Procedure 2: To a solution of potassium tert-butoxide (20 mmol) in 20 ml of anhydrous THF was added 2-cyanoacetamide (20 mmol). The mixture was cooled to 5° C. and a solution of isothiocyanates (20 mmol) in 5 ml of dry THF was added dropwise with stirring under argon. After 15 min with stirring at 5° C., the reaction mixture was warmed to room temperature and stirred for another 1 h. The reaction mixture was poured into 1000 ml of ice water and neutralized with 2% HCl solution to pH<7. The solid was filtered and washed with water. After drying in vacuo, the crude product was obtained and it is pure enough for next step (Yield: 72-97%).
Cyclization: The above dried solid was dissolved in ethyl acetate (30 ml), and a solution of bromine (0.31 ml, 6 mmol) in ethyl acetate (25 ml) was added drop wise into the mixture. After 1 hour of stirring at room temperature, the reaction mixture was filtered, and the solid was washed with ethyl acetate and dried in vacuo to afford a yellow powder (0.86 g, 66%).
Preparation of 5-benzimidazole, oxazole, thiazole, and isothiazole carboxamidines




The 2-(4-aminophenyl)benzoxazole, benzothiazole, or benzimidazole was prepared by condensation of the appropriate aniline derivative with p-amino benzoic acid using polyphosphoric acid. The product was converted to the corresponding isothiocyanate with thiophosgene and subsequently condensed with cyanoacetamide to form the thiocarbamoyl cyanoacetamide. Treatment with bromine afforded the cyano hydroxy thiazole, which was converted to carboxamidine by treatment with the appropriate amide, as shown above.
PREPARATION OF EXAMPLES
A typical procedure for synthesis of isothiazole carboxamidines is that employed for synthesis of 3-hydroxy-N-isopropyl-5-(4-phenoxyphenylamino)-isothiazole-4-carboxamidine:
A mixture of 3-hydroxy-4-cyano-5-(4-phenoxyphenylamino)isothiazole (5 g) and isopropylamine (25 ml) in 250 ml of ethanol was placed into a high-pressure reaction equipment and heated to 120° C. with stirring for 9 hours. The reaction mixture was cooled to room temperature, and the solvent was removed under vacuum. The residue was treated with 500 ml of diethyl ether, and the precipitates were filtered and washed with diethyl ether. The filtrates were evaporated to dryness, and the residue was purified by silica gel column chromatography (chloroform/methanol, 60:1) to give 3.51 g (59%) of product as a foam, which was recrystallized from methanol to give yellowish crystals. MS: 368; 1H NMR (DMSO-d6): 10.44 (brs, 1/2H, NH, D2O exchangeable), 9.81 (brs, 1/2H, NH, D2O exchangeable), 9.51 (brs, 1/2H, NH, D2O exchangeable), 9.15 (brs, 1/2H, NH, D2O exchangeable), 8.36 (s, 1H, OH, D2O exchangeable), 7.87 (brs, 1/2H, NH, D2O exchangeable), 7.66 (brs, 1/2H, NH, D2O exchangeable), 7.35 (t, 2H, J=7.5 Hz, ArH), 7.08 (t, 1H, J=7.5 Hz, ArH), 6.96 (m, 6H, ArH), 3.85 (m, 1H, CH), 1.20 (d, 6H, J=6.3 Hz, 2×CH3).
The isothiazole carboxamidines listed in table 2 were synthesized by the procedure above. Most reactions were run using 100-200 mg of starting materials in about 20-30 ml of ethanol at 90° C. for 24-48 hours. In most cases products were purified by silica gel column chromatography. Some compounds were purified by preparative HPLC or TLC.
N-Cyclohexylmethyl-3-hydroxy-5-(3-phenoxy-phenylamino)-isothiazole-4-carboxamidine




To a suspension of 85% powdered KOH in 20 ml DMF was added 1.74 g of cyanoacetamide at room temperature. The solution was stirred at room temperature for 15 minutes and then cooled in a water bath at room temperature. To this solution 4.7 g of 3-phenoxy-phenyl isothiocyanate was added dropwise. The solution exothermed slightly with the internal temperature rising to 28° C. during the addition. The solution was stirred at room temperature for 16 h, then diluted with 150 ml water and extracted with ethyl acetate to remove small amounts of starting material and by-products. The aqueous layer was isolated and acidified with 1N HCl to pH 1 with vigorous stirring. The resulting tan precipitate was filtered, washed with water, and dried for 16 hours in a vacuum oven to afford 4.66 g of 2-cyano-2-(3-phenoxy-phenylthiocarbamoyl)-acetamide.
The product of the previous step was suspended in 100 ml ethyl acetate and stirred vigorously. A solution of 767 μl Br2 in 25 ml ethyl acetate was added via addition funnel over 30 minutes. After 1.5 h, saturated aqueous NaHCO3 was added, and the resulting biphasic mixture was stirred for 30 minutes. The mixture was filtered and washed with ethyl acetate, followed by water and dried in vacuo to afford 2.75 g (43%) of 3-hydroxy-5-(3-phenoxy-phenylamino)-isothiazole-4-carbonitrile as a tan solid. To a suspension of 190 mg of this material in 10 ml ethyl alcohol in a 40 ml Teflon-lined screw-thread vial was added 500 μl cyclohexyl methylamine and heated to 80° C. After 18 h, the reaction was cooled and the solvent evaporated. The residue was purified by preparative HPLC to afford 26 mg (10%) of N-cyclohexylmethyl-3-hydroxy-5-(3-phenoxy-phenylamino)-isothiazole-4-carboxamidine as a tan solid. 1H NMR ((CD3)2SO) δ 0.969 m 2H, 1.161 m 3H, 1.718-1.510 m 6H, 3.109 t 2H J=6.3 Hz, 6.473 s 1H, 6.633 dd 1H J=2.1 and 7.8 Hz, 6.698 dd 1H J=1.2 and 7.8 Hz, 7.014 d 2H J=7.8 Hz, 7.130 t 1H J=7.5 Hz, 7.276 t 1H, J=7.2 Hz, 7.381 t 2H J=8.1 Hz, 7.691 bs 1/2H, 8.416 s 1H, 9.099 bs 1/2H, 9.745 bs 1/2H, 10.566 bs 1/2H.

4-isothiocyanato-benzoic acid t-butyl ester 2: t-Butyl-4-aminobenzoate 1, (25.0 gm, 129.4 mmol) was taken into CHCl3 (250 ml) and saturated NaHCO3 (100 ml) in ice bath. To the stirred mixture thiophosgene (9.9 ml, 129.4 mmol) was added dropwise, and stirring continued for another 90 min. at room temperature after addition was complete. The organic layer was washed with water, dried over Na2SO4, and further purified by column chromatography to provide 28.3 gm of 4-isothiocyanato-benzoic acid t-butyl ester 2.
4-(2-carbamoyl-2-cyano-thioacetylamino)-benzoic acid t-butyl ester 3: 4-Isothiocyanato-benzoic acid t-butyl ester 2 (28.3 gm, 120.4 mmol) was taken into DMF (200 ml). To this KOH (6.74 gm, 120.4 mmol) and cyanoacetamide (10.21 gm, 120.4 mmol) were added. The reaction mixture was stirred at room temperature for 16 h. The reaction mixture was acidified with 1N HCl, the precipitate obtained was filtered, washed with water, and dried under vacuum, to provide 32.10 gm of 4-(2-Carbamoyl-2-cyano-thioacetylamino)-benzoic acid t-butyl ester 3.
4-(4-cyano-3-hydroxy-isothiazole)-benzoic acid 4: 4-(2-carbamoyl-2-cyano-thioacetylamino)-benzoic acid t-butyl ester 3 (32.10 gm, 100.36 mmol) was taken into EtOAc (250 ml) and to this Br2 (5.2 ml, 100.36 mmol) was added slowly. Reaction mixture was stirred at room temperature for 2 h. The precipitate obtained was filtered and washed with saturated NaHCO3 and dried under vacuum to provide 31 gm of 4-(4-cyano-3-hydroxy-isothiazole)-benzoic acid 4.
5-[3-(3-(1H-indole-1-carbonyl)phenylamino]-3-hydroxyisothiazole-4-carbonitrile 5: 4-(4-cyano-3-hydroxy-isothiazole)-benzoic acid 4 (1.0 gm, 3.82 mmol) was taken into DMF (30 ml). To this solution DMAP (0.46 gm, 3.82 mmol), EDC (0.732 gm, 3.82 mmol) and indoline (1.28 gm, 3.82 mmol) were added. The reaction mixture was stirred at room temperature for 16 h., concentrated to dryness, and purified by column chromatography to provide 1.08 gm of 5-[4-(2,3-dihydro-indole-1-carbonyl)-phenylamino]-3-hydroxy-isothiazole-4-carbonitrile 5.
5-[3-(3-(1H-indole-1-carbonyl)phenylamino]-3-hydroxy-N-(1-hydroxypropan-2-yl)isothiazole-4-carboximidamide 6: 5-[3-(3-(1H-indole-1-carbonyl)phenylamino]-3-hydroxyisothaizole-4-carbonitrile 5: (0.362 gm, 1 mmol) was taken into anhydrous EtOH (10 ml) and to this 2-amino-propan-1-ol (0.375 gm, 5 mmol) was added. The reaction mixture was stirred at 80° C. for 16 h., then concentrated to dryness and purified by column chromatography to provide 5-[4-(2,3-dihydro-indole-1-carbonyl)-phenylamino]-3-hydroxy-N-(2-hydroxy-1-methyl-ethyl)-isothiazole-4-carboxamidine 6.
Biological Data
Selected compounds were used in various assays to evaluate inhibitory activity of the compounds according to the inventive subject matter, and experimental procedures and results are indicated in tables below, where, unless otherwise indicated, “A” denotes inhibitory concentrations of 1 nM-100 nM, “B” denotes inhibitory concentrations of 100 nM-500 nM, and “C” denotes inhibitory concentrations of greater than 500 nM (hydroxy groups in the structures of the table below are denoted as single bonded oxygen as the structures were generated in “hide proton view”).
Generation of IC50 Data
Materials and preparation of reagents: Human GST-MEK1 and the constitutively active allele GST-MEK1CA (harboring the mutations Ser218Asp and Ser222Asp) were subcloned into the yeast expression vector pGEM4Z (Promega, Madison, Wis.) from the wild type human MEK1 cDNA. GST-MEK1CA was expressed in Escherichia coli and partially purified using Glutathione Sepharose 4B affinity resin (Amersham Pharmacia Biotech, Piscataway, N.J.). The ERK2 allele was subcloned from MAPK2/Erk2 cDNA (wild type) in pUSEamp (Upstate Biotechnology, Inc., Waltham, Mass.) into the vector pET21a (Novagen, Madison, Wis.) resulting in an N-terminal histidine-tagged mouse ERK2 allele. ERK2 was expressed and purified to homogeneity [Zhang, 1993 #33]. Myelin basic protein (MBP) was purchased from Gibco BRL (Rockville, Md.). EasyTides adenosine 5′-triphosphate (ATP) ([γ-33P]) (NEN Perkin Elmer, Wellesley, Mass.) was the source of radiolabel for all kinase reactions. Activated Raf-1 (truncated) and activated MAPKinase 2/ERK2 were purchased from Upstate, Inc. (Lake Placid, N.Y.). 4-20% Criterion Precast gels were purchased from Bio-Rad (Hercules, Calif.).
Determination of enzymatic activity: Compounds were diluted from dimethylsulfoxide (DMSO) stocks into 1×HMNDE (20 mM HEPES pH 7.2, 1 mM MgCl2, 100 mM NaCl, 1.25 mM DTT, 0.2 mM EDTA). A typical 25-microliter assay contained 0.002 nanomoles MEK1CA, 0.02 nanomoles ERK2, 0.25 nanomoles MBP, 0.25 nanomoles unlabeled ATP, and 0.1 μCi [γ33P] ATP. The screening assay essentially comprised four additions. Five μl of diluted compound were dispensed to 96-well assay plates. Ten μl of 2.5× enzyme cocktail (MEK1CA and ERK2 only) were then added to each well followed by a pre-incubation for 30 minutes at ambient temperature. Ten μl of 2.5× substrate cocktail (labeled and unlabeled ATP plus MBP) were then added, followed by incubation for 60 minutes at ambient temperature. Finally, 100 μl of 10% trichloroacetic acid (TCA) were added and incubated for 30 minutes at room temperature to halt the reaction and precipitate radiolabeled protein products. Reaction products were harvested on glass fiber 96 well filter plates prewetted with water and 1% pyrophosphate. The filter plate was then washed 5 times with water. Water was displaced by absolute ethanol and the plate was allowed to air dry for 30 minutes at room temperature. A back seal was applied manually and 40 μl of scintillation cocktail were dispensed to each well. A top seal was applied and the plate was counted in the TopCount for two seconds per well.
Generation of EC50 Data
Effects of compounds in the cell were determined by Western blotting for phosphorylated ERK. MDA-MB-231 breast cancer cells were plated in a 48 well plate at 20,000 cells per well and grown in a 37° humidified CO2 incubator. The following day, the growth media (DMEM+10% fetal bovine serum) was removed and replaced with starve media (DMEM+0.1% fetal bovine serum). Cells were incubated in the starve media for sixteen hours and then treated with a range of compound concentrations for thirty minutes. After incubation with compound, cells were stimulated with 100 ng/ml EGF for five minutes. The cells were then lysed and analyzed by Western blot using a monoclonal antibody raised to phosphorylated ERK. The signal was amplified using a secondary antibody conjugated to a near −IR dye and detected on a Licor Odyssey scanner. The intensity of signal was quantitated and this data was used to generate dose response curves and EC50 calculations.
