Niraparib

Niraparib is an orally active poly (ADP-ribose) polymerase (PARP) inhibitor. By blocking the enzymes responsible for DNA repair, niraparib induces cytotoxicity in cancer cells. Niraparib is selective towards PARP-1 and PARP-2. Niraparib is specifically metabolized by carboxylesterase 1 via amide hydrolysis to an acid metabolite
