What is Rucaparib?

Plain description, key identifiers and synonyms

Rucaparib is a member of the class of azepinoindoles that is 1,3,4,5-tetrahydro-6H-azepino[5,4,3-cd]indol-6-one carrying additional 4-[(methylamino)methyl]phenyl and fluoro substituents at positions 2 and 8 respectively. It is an inhibitor of poly (ADP-ribose) polymerase and is used (as the camsylate salt) as monotherapy for advanced ovarian cancer and deleterious germline or somatic BRCA mutation. It has a role as an antineoplastic agent and an EC 2.4.2.30 (NAD(+) ADP-ribosyltransferase) inhibitor. It is an azepinoindole, a member of caprolactams, an organofluorine compound and a secondary amino compound. It is a conjugate base of a rucaparib(1+).
