FIELD OF THE INVENTION

[0002]This invention is related to at least one compound selected from a compound of formula I

##STR00002##

[0003]or the pharmaceutically acceptable salts thereof, wherein X.sub.1, X.sub.2, X.sub.3, R, Y.sub.1 and Y.sub.2 are described in this application. These compounds are believed to inhibit the interaction of MDM2 protein with a p-53-like peptide and have antiproliferative activity.

BACKGROUND OF THE INVENTION

[0004]p53 is a tumor suppresser protein that plays a central role in protection against development of cancer. It guards cellular integrity and prevents the propagation of permanently damaged clones of 1 cells by the induction of growth arrest or apoptosis. At the molecular level, p53 is a transcription factor that can activate a panel of genes implicated in the regulation of cell cycle and apoptosis. p53 is a potent cell cycle inhibitor which is tightly regulated by MDM2 at the cellular level. MDM2 and p53 form a feedback control loop. MDM2 can bind p53 and inhibit its ability to transactivate p53-regulated genes. In addition, MDM2 mediates the ubiquitin-dependent degradation of p53. p53 can activate the expression of the MDM2 gene, thus raising the cellular level of MDM2 protein. This feedback control loop insures that both MDM2 and p53 are kept at a low level in normal proliferating cells. MDM2 is also a cofactor for E2F, which plays a central role in cell cycle regulation.

[0005]The ratio of MDM2 to p53 (E2F) is dysregulated in many cancers. Frequently occurring molecular defects in the p161NK4/p19ARF locus, for instance, have been shown to affect MDM2 protein degradation. Inhibition of MDM2-p53 interaction in tumor cells with wild-type p53 should lead to accumulation of p53, cell cycle arrest and/or apoptosis. MDM2 antagonists, therefore, can offer a novel approach to cancer therapy as single agents or in combination with a broad spectrum of other antitumor therapies. The feasibility of this strategy has been shown by the use of different macromolecular tools for inhibition of MDM2-p53 interaction (e.g. antibodies, antisense oligonucleotides, peptides). MDM2 also binds E2F through a conserved binding region as p53 and activates E2F-dependent transcription of cyclin A, suggesting that MDM2 antagonists might have effects in p53 mutant cells.

SUMMARY OF THE INVENTION

[0009]The present invention provides at least one compound of formula I

and the pharmaceutically acceptable salts and esters thereofwherein X.sub.1, X.sub.2, X.sub.3, R, Y.sub.1, and Y.sub.2 are as herein described.

DETAILED DESCRIPTION OF THE INVENTION

[0010]The present invention provides chiral cis-imidazolines which are small molecule inhibitors of the MDM2-p53 interaction. In cell-free and cell-based assays, compounds of the present invention are shown to inhibit the interaction of MDM2 protein with a p53-like peptide with a potency that is approximately 100 fold greater than a p53-derived peptide. In cell-based assays, these compounds demonstrate mechanistic activity. Incubation of cancer cells with wild-type p53 leads to accumulation of p53 protein, induction of p53-regulated p21 gene, and cell cycle arrest in G1 and G2 phase, resulting in potent antiproliferative activity against wild-type p53 cells in vitro. In contrast, these activities were not observed in cancer cells with mutant p53 at comparable compound concentrations. Therefore, the activity of MDM2 antagonists is likely linked to its mechanism of action. These compounds can be potent and selective anticancer agents.

[0171]The compounds of the present invention can be prepared according to the following scheme 1.

##STR00006##

[0172]The synthesis commences with the coupling reaction of the benzoic acid ester 2 (Z=methyl, ethyl, etc.) with diamine 1 (prepared according to the procedure described by Jennerwein, M. et al. Cancer Res. Clin. Oncol. 1988, 114, 347-58; Vogtle, F.; Goldschmitt, E. Chem. Ber. 1976, 109, 1-40) using trimethylaluminum as a catalyst in a solvent such as toluene with heating at reflux (Moormann, A. E. et al J. Med. Chem. 1990, 33, 614-626). Benzoic acid esters 2 are prepared using the procedures known in the art. Treatment of the cis-imidazoline 3 with phosgene in the presence of a base such as triethylamine gives the racemic carbamoyl chloride 4. Coupling of the racemic carbamoyl chloride 4 with appropriate R amine groups provides the compounds of the formula I as racemic mixtures. Many R amine groups are commercially available. If it is desired, R amine groups can be prepared using synthetic methods known in the art. Suitable processes for making these R amine groups are provided in the examples.

[0173]If it is desired to prepare the optically active compounds of formula I, the enantiomers of the carbamoyl chloride rac-4 can be separated using chiral chromatography. The chiral stationary phase R,R-Whelk-O1, available through Regis Technologies, can be used. Coupling of the desired enantiomer 5A with appropriate R amine groups provides the compounds of the formula I.

[0174]Also the optically active compounds of formula I can be obtained by chiral separation of the racemic mixtures of I. The chiral stationary phase Diacel ChiralPak OD or AD can be used.

[0175]The absolute stereochemistry of the preferred enantiomer of 1 is determined based on the crystal structure of its complex with the human MDM2 (Vassilev et al. Science, 2004, 303, 844-848.

[0176]The following examples and references are provided to aid the understanding of the present invention, the true scope of which is set forth in the appended claims.

EXAMPLE 1

##STR00007##

[0177]a) Methyl 4-tert-butyl-2-ethoxybenzoate

[0178]A solution of 3-tert-butylphenol (100 g, 665.7 mmol, TCI) and potassium hydroxide (37.35 g, 665.7 mmol) in 260 mL of water was added to a vigorously stirred solution of iodine (202.8 g, 798.8 mmol) and potassium hydroxide (89.95 g, 1598 mmol) in 1100 mL of water. The combined solution immediately turned white. It was stirred for 5 min. A small sample of the reaction mixture was removed, acidified and extracted with ethyl acetate. Thin layer chromatography (silica gel, 30% methylene chloride in hexane) showed the product (lower Rf) and some starting material. Methylene chloride (450 mL) was added, and sulfuric acid solution was added until a permanent brown color appeared (pH .about.7). The layers were separated, and the organic layer was washed with water until it was neutral. The solvents were evaporated to dryness to give a reddish oil (162 g). The crude oil was purified by flash column chromatography (silica gel, eluting with hexane, 5-10% methylene chloride in hexane) to give 5-tert-butyl-2-iodo-phenol (132.7 g) as an amber oil (solidified upon standing).

[0179]The mixture of 5-tert-butyl-2-iodo-phenol (132.7 g, 480.6 mmol), potassium carbonate (265.7 g, 1923 mmol) and ethyl iodide (76.9 mL, 961.3 mmol) in ethanol (1.125 mL) was heated at reflux overnight. Upon cooling to room temperature, the reaction mixture was diluted with diethyl ether. The white solids were filtered off, and the filtrate was concentrated in vacuo to give 4-tert-butyl-2-ethoxy-1-iodo-benzene (144.7 g) as pale yellow oil.

[0180]In a 2 L pressure reaction flask was placed 4-tert-butyl-2-ethoxy-1-iodo-benzene (142 g, 466.9 mmol), dimethylformamide (275 mL), methanol (500 mL) and triethylamine (130 mL, 933.7 mmol). Argon was bubbled through the mixture for 1 h. Bis(triphenylphosphine)-palladium(II) chloride (19.69 g, 28.05 mmol) was added. The flask was evacuated then pressurized with carbon monoxide (40 psi) five times. The reaction was heated overnight at 65.degree. C. under carbon monoxide pressure (40 psi). Upon cooling to room temperature, the reaction mixture was diluted with ethyl acetate (1400 mL) and washed with water (2.times.600 mL), brine (1.times.200 mL), and dried over anhydrous magnesium sulfate. The solids were filtered off, and the filtrate was concentrated to dryness to give dark oil (160 g). It was taken in ethyl acetate (160 mL), and hexane (1200 mL) was added while stirring vigorously. After the mixture was settled, the supernatant was removed. The same procedure was repeated two more times with ethyl acetate and hexane. The combined supernatant was treated with charcoal then filtered. The filtrate was concentrated in vacuo. It may be necessary to repeat the same procedure with ethyl acetate and hexane if there are still more solids present. The crude product was purified by flash chromatography (silica gel, eluting with 4% ethyl acetate in hexane) to give 93.5 g of methyl 4-tert-butyl-2-ethoxy-benzoate as a red oil.

b) Methyl 4-tert-butyl-2,5-diethoxybenzoate: prepared from 2-tert-butylhydroquinone in an analogous manner as described in example 1a.

[0182]Ethyl 5-tert-butyl-2-ethoxybenzoate

[0183]5-tert-Butyl-2-hydroxy-benzaldehyde (1.4 g, 6.0 mmol, prepared according to Smith W. E. J. Org. Chem. 1972, 37, 3972-3973) was taken up in 30 ml, of a 2M solution of 2-methyl-2-butene in tetrahydrofuran. t-Butanol (30 ml.) was added. Sodium dihydrogenphosphate (2.6 g, 18.8 mmol) and sodium chlorite (1.4 g, 12.3 mmol) were then added as a solution in 12 mL of water. The reaction mixture was stirred at room temperature for 2 h. It was diluted with ethyl acetate and washed with 1N hydrochloric acid. The aqueous layers were extracted three times with ethyl acetate. The combined organic layers were washed with a saturated solution of Na.sub.2S.sub.2O.sub.3, brine, and dried over anhydrous magnesium sulfate. The solids were filtered off, and the filtrate was concentrated to give 5-tert-butyl-2-hydroxy-benzoic acid (1.5 g, quant.), which was used in the next step without further purification.

[0184]Potassium carbonate (9.4 g, 68.0 mmol) and iodoethane (3.3 mL, 41.3 mmol) were added to a stirred solution of 5-tert-butyl-2-hydroxy-benzoic acid (1.3 g, 6.8 mmol) in 2-butanone (50 mL). The resulting mixture was heated at 80.degree. C. (oil bath) for 16 h and then allowed to cool. The solution was concentrated and redissolved in methylene chloride. The organic phase was washed with water, brine, and dried over anhydrous magnesium sulfate. The solids were filtered off, and the filtrate was concentrated. Purification of the crude residue by flash chromatography (silica gel, eluting with 5-10% ethyl acetate in hexanes) gave ethyl 5-tert-butyl-2-ethoxy-benzoate (1.2 g, 81%) as a yellow oil.

[0186]Methyl 4-(cyano-dimethylmethyl)-2-ethoxy-benzoate

[0187]2-(3-Ethoxy-phenyl)-2-methyl-propionitrile was prepared using a procedure adapted from literature (Organic Syntheses, Vol. 79, pp. 209-215). To a solution of 1-ethoxy-3-fluoro benzene (3.0 g, 19.4 mmol) in 25 mL of toluene was added solid potassium bis(trimethylsilyl)amide (5.84 g, 29.2 mmol, 1.5 eq) followed by isobutyronitrile (7.08 mL, 77.8 mmol, 4 eq). The reaction mixture was stirred at 100.degree. C. for 12 hr. It was diluted with 75 mL of ethyl acetate and 75 mL of 1N aqueous hydrochloric acid. The layers were separated, and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with water (1.times.50 mL), brine (1.times.50 mL), and dried over anhydrous magnesium sulfate. The solids were filtered off, and the filtrate was concentrated in vacuo. The residue was dissolved in 5 mL of methylene chloride and applied to a 40 g silica gel cartridge. The product was eluted using a gradient of ethyl acetate in hexanes to yield 2.96 g (15.6 mmol, 80%) of pure 2-(3-ethoxy-phenyl)-2-methyl-propionitrile. LR-MS: 190.12 [(M+H).sup.+]

[0188]2-(3-Ethoxy-phenyl)-2-methyl-propionitrile (2.96 grams, 15.65 mmol) was dissolved in a freshly prepared acetic acid solution of iodine monochloride (20 mL of a 1.54 M iodine monochloride solution in acetic acid, 30.8 mmol). The reaction was slightly exothermic. The reaction mixture was allowed to stand at room temperature for 3 d. The reaction mixture was concentrated, and the residue was partitioned between ethyl acetate and water. The organic layer was washed with 10% sodium carbonate (1.times.), brine (1.times.), and dried (anhydrous magnesium sulfate). The solids were filtered off, and the filtrate was concentrated to dryness. The residue was purified by flash chromatography (110 g of silica gel, eluting with a gradient of ethyl acetate in hexanes) to give 2-(3-ethoxy-4-iodo-phenyl)-2-methyl-propionitrile (2.53 g, 51%). LR-MS: 316.21 [(M+H).sup.+]

[0189]Nitrogen gas was bubbled through a solution of (3-ethoxy-4-iodo-phenyl)-2-methyl-propionitrile (2.53 grams, 8 mmol) and diisopropylethylamine (2.09 mL, 12 mmol) in methanol (10 mL). Using a balloon filled with carbon monoxide gas (CO) and equipped with a needle, CO was bubbled through the mixture until it was saturated. Palladium (II) acetate (100 mg) was added, and the mixture was stirred under an atmosphere of CO at 60.degree. C. for 6 d. The reaction mixture was filtered and concentrated. The residue was partitioned between methylene chloride and 1.0M hydrochloric acid. The organic layer was dried (anhydrous magnesium sulfate), filtered. The residue was purified by flash chromatography (120 g of silica gel, eluting with a gradient of ethyl acetate in hexanes) to give methyl 4-(cyano-dimethylmethyl)-2-ethoxy-benzoate (1.09 g, 55%).

[0191]Methyl 2-ethoxy-4-(2-hydroxy-1,1-dimethylethyl)benzoate

[0192]Potassium carbonate (65.3 g, 473 mmol) and iodoethane (25.5 mL, 324 mmol) were added to a stirred solution of 3-hydroxyphenylacetic acid (12.0 g, 79 mmol) in 2-butanone (125 mL). The resulting mixture was heated in an oil bath (80.degree. C.) for 16 h and then allowed to cool. The mixture was concentrated and methylene chloride was added. The organic layer was washed with water, brine, and dried over anhydrous magnesium sulfate. The solids were filtered off, and the filtrate was concentrated to give ethyl 3-ethoxyphenylacetate (12.7 g, 78%) as a clear oil.

[0193]Potassium hydride (32 g, 240 mmol, 30% in mineral oil) was washed twice with hexanes and dried. To this was added dropwise with ice-cooled tetrahydrofuran (60 mL), followed by a solution of ethyl 3-ethoxyphenylacetate (12.7 g, 61 mmol) in tetrahydrofuran (20 mL) and finally methyl iodide (8.4 mL, 134 mmol). The reaction mixture was stirred at room temperature overnight and partitioned between aqueous sodium bicarbonate and methylene chloride. The organic layer was dried over anhydrous magnesium sulfate and concentrated to give ethyl dimethyl-3-ethoxyphenylacetate (13.6 g, 94%) as a pale yellow oil.

[0194]To a cooled solution (5.degree. C.) of ethyl dimethyl-3-ethoxyphenylacetate (5.0 g, 21.1 mmol) in acetic acid (40 mL) was added dropwise a solution of iodine monochloride (5.0 g, 30.9 mmol) in acetic acid.

[0557]A solution of 2-(4-iodo-3-methoxy-phenyl)-2-methyl-propionic acid (326 mg, 0.976 mmol, prepared by saponification of ethyl dimethyl-(3-ethoxy-4-iodophenyl)acetate, example 4) in thionyl chloride (5 mL) was heated at reflux for 1 h. It was concentrated to dryness then taken in 5 mL of tetrahydrofuran. Diethylamine (1 mL, 2 mmol, 2M solution in tetrahydrofuran) was added. The reaction mixture was stirred at room temperature overnight. It was diluted with ethyl acetate, washed with brine (1.times.), dried over anhydrous sodium sulfate and concentrated. Purification of the crude residue by flash column chromatography (silica gel, IntelliFlash 280, eluting with a gradient of 5-95% ethyl acetate in hexanes) gave N,N-diethyl-2-(4-iodo-3-methoxy-phenyl)-isobutyramide (361.4 rig, 95%) as clear oil.

In Vitro Activity Assay

[0565]The ability of the compounds to inhibit the interaction between p53 and MDM2 proteins was measured by an HTRF (homogeneous time-resolved fluorescence) assay in which recombinant GST-tagged MDM2 binds to a peptide that resembles the MDM2-interacting region of p53 (Lane et al.). Binding of GST-MDM2 protein and p53-peptide (biotinylated on its N-terminal end) is registered by the FRET (fluorescence resonance energy transfer) between Europium (Eu)-labeled anti-GST antibody and streptavidin-conjugated Allophycocyanin (APC).

[0566]Test is performed in black flat-bottom 384-well plates (Costar) in a total volume of 40 uL containing: 90 nM biotinylate peptide, 160 ng/ml GST-MDM2, 20 nM streptavidin-APC (PerkinElmerWallac), 2 nM Eu-labeled anti-GST-antibody (PerkinElmerWallac), 0.2% bovine serum albumin (BSA), 1 mM dithiothreitol (DTT) and 20 mM Tris-borate saline (TBS) buffer as follows: Add 10 uL of GST-MDM2 (640 ng/ml working solution) in reaction buffer to each well. Add 10 uL diluted compounds (1:5 dilution in reaction buffer) to each well, mix by shaking. Add 20 uL biotinylated p53 peptide (180 nM working solution) in reaction buffer to each well and mix on shaker. Incubate at 37.degree. C. for 1 h. Add 20 uL streptavidin-APC and Eu-anti-GST antibody mixture (6 nM Eu-anti-GST and 60 nM streptavidin-APC working solution) in TBS buffer with 0.2% BSA, shake at room temperature for 30 minutes and read using a TRF-capable plate reader at 665 and 615 nm (Victor 5, Perkin ElmerWallac). If not specified, the reagents were purchased from Sigma Chemical Co.
