Rucaparib (CAS No.:283173-50-2) is a PARP inhibitor used as an anti-cancer agent. Rucaparib is a first-in-class pharmaceutical drug targeting the DNA repair enzyme poly-ADP ribose polymerase-1 (PARP-1). It was discovered as part of a collaboration between scientists working at the Northern Institute of Cancer Research and Medical School of Newcastle University and Agouron Pharmaceuticals in San Diego, California.It is being developed by Clovis Oncology.
Rucaparib, also known as (AG-14699 or PF-01367338, is a tricyclic indole poly(ADP-Ribose) polymerase (PARP1) inhibitor with potential chemosensitizing, radiosensitizing, and antineoplastic activities. Rucaparib selectively binds to PARP1 and inhibits PARP1-mediated DNA repair, thereby enhancing the accumulation of DNA strand breaks and promoting genomic instability and apoptosis. This may enhance the cytotoxicity of DNA-damaging agents and reverse tumor cell resistance to chemotherapy and radiation therapy.
