Pharmacology
Talazoparib is an inhibitor of PARP enzymes (PARP1 and PARP2) involved in DNA repair; it induces cytotoxicity in cancer cells with DNA repair gene defects through inhibition of PARP enzymatic activity and increased formation of PARP-DNA complexes, resulting in DNA damage, decreased cell proliferation, and apoptosis.
Enzalutamide is an androgen receptor inhibitor that competitively inhibits androgen binding to androgen receptors and consequently inhibits nuclear translocation of androgen receptors and their interaction with DNA; its major metabolite, N-desmethyl enzalutamide, exhibits similar in vitro activity.
