rucaparib camsylate
Patient Information
The camsylate salt form of rucaparib, an inhibitor of the nuclear enzyme polyadenosine 5’-diphosphoribose (poly-ADP-ribose) polymerase (PARP), with chemosensitizing, radiosensitizing, and antineoplastic activities. Upon administration, rucaparib selectively binds to PARP-1, PARP-2 and PARP-3, and inhibits PARP1-mediated repair of single-strand DNA (ssDNA) breaks via the base-excision repair pathway; this enhances the accumulation of DNA strand breaks and promotes genomic instability and apoptosis. Rucaparib may potentiate the cytotoxicity of DNA-damaging agents and reverse tumor cell resistance to chemotherapy and radiation therapy. PARP catalyzes post-translational ADP-ribosylation of nuclear proteins and is activated by ssDNA breaks. Check for active clinical trials using this agent. (NCI Thesaurus)
