Background

A-966492 is an inhibitor of PARP-1 with Ki value of 1nM [1].

PARP-1 belongs to the poly(ADP-ribose) polymerases (PARPs) family, it contributes to the resistance happened after cancer therapy. A-966492 is a potent inhibitor of both PARP-1 and PARP-2 (Ki value of 1.5nM) with good potency in C41 whole cells (EC50 value of 1nM). A-966492 shows excellent pharmaceutical properties with oral bioavailabilities of 34-72% and half-lives of 1.7-1.9 h. Additionally, A-966492 can crosses the blood-brain barrier. A-966492 is proved potent in a murine B16F10 syngeneic melanoma model and a BRCA1-deficient MX-1 breast carcinoma model. Meanwhile, it can enhance the efficacy of TMZ and carboplatin in these models [1].
