PHARMACEUTICALLY ACCEPTABLE SALTS OF 2-{4-[(3S)-PIPERIDIN-3-YL]PHENYL}-2H-INDAZOLE-7-CARBOXAMIDE

摘要

The present invention relates to pharmaceutically acceptable salts of an amide substituted indazole which are inhibitors of the enzyme poly(ADP-ribose)polymerase (PARP), previously known as poly(ADP-ribose)synthase and poly(ADP-ribosyl)transferase. The compounds of the present invention are useful as mono-therapies in tumors with specific defects in DNA-repair pathways and as enhancers of certain DNA-damaging agents such as anticancer agents and radiotherapy. Further, the compounds of the present invention are useful for reducing cell necrosis (in stroke and myocardial infarction), down regulating inflammation and tissue injury, treating retroviral infections and protecting against the toxicity of chemotherapy.
