Iniparib (INN,[1] previously known as BSI 201) was a drug candidate for cancer treatment. It was originally believed to act as an irreversible inhibitor of PARP1 (hence, a PARP inhibitor) and possibly other enzymes through covalent modification,[2][3] but its effects against PARP were later disproven.[4][5] It underwent clinical trials for treatment of some types of breast cancer,[6][7] but was discontinued after disappointing phase III clinical trials.
