Salts and crystalline forms of an apoptosis-inducing agent
View Patent ↗Salts and crystalline forms of 4-(4-{[2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-en-1-yl]methyl}piperazin-1-yl)-N-({3-nitro-4-[(tetrahydro-2H-pyran-4-ylmethyl)amino]phenyl}-sulfonyl)-2-(1H-pyrrolo[2,3-b]pyridin-5-yloxy)benzamide are suitable active pharmaceutical ingredients for pharmaceutical compositions useful in treatment of a disease characterized by overexpression of one or more anti-apoptotic Bcl-2 family proteins, for example cancer.
1. A compound 4-(4-{[2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-en-1-yl]methyl}piperazin-1-yl)-N-({3-nitro-4-[(tetrahydro-2H-pyran-4-ylmethyl)amino]phenyl}sulfonyl)-2-(1H-pyrrolo[2,3-b]pyridin-5-yloxy)benzamide (Compound 1) in a crystalline form wherein the crystalline form is Compound 1 free base anhydrate, characterized by a powder X-ray diffraction pattern having five or more peaks selected from those at 6.3, 7.1, 9.0, 9.5, 12.5, 14.5, 14.7, 15.9, 16.9, and 18.9 degrees 2θ (pattern A), each peak being ±0.2 degrees 2θ, when measured at about 25° C. with Cu K α radiation at 1.54178 Å.
2. A pharmaceutical composition comprising the compound in said crystalline form of claim 1 and one or more pharmaceutically acceptable excipients.
3. A process for preparing a pharmaceutical solution comprising dissolving the compound in said crystalline form of claim 1 in a pharmaceutically acceptable solvent or mixture of solvents.
