A-966492 effectively inhibits PARP-1 with an EC50 of 1 nM and a Ki value of 1 nM. When it acts on PARP-2, the Ki value is 1.5 nM. It has excellent efficacy on PARP enzyme, especially on C41 cells. A-966492 significantly enhanced the effect of TMZ in a dose-dependent manner. | [Biological Activity]
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]. | [Synthesis]
A-966492 is prepared by reacting 3-Carboxamido-1,2-phenylenediamine with benzoic acid in a solution(methanol:water=1:1) at 50 °C for 2 hours. | [References]
