is important for clarifying specific roles of PARP-2 in the pathophysiological process and developing desired drugs with reduced off-target side effects. In this work, a series of novel quinazoline-2,4(1H,3H)-dione derivatives was designed and synthesized to explore isoform selective PARP inhibitors. As a result, compound 11a (PARP-1 IC50 = 467 nM, PARP-2 IC50 = 11.5 nM, selectivity PARP-1/PARP-2 = 40
PARP-2选择性抑制剂对于阐明PARP-2在病理生理过程中的特定作用以及开发具有减少脱靶副作用的所需药物非常重要。在这项工作中,设计并合成了一系列新颖的喹唑啉-2,4(1 H,3 H)-二酮衍生物,以探索同工型选择性PARP抑制剂。结果,化合物11a(PARP-1 IC 50 = 467 nM,PARP-2 IC 50 = 11.5 nM,选择性PARP-1 / PARP-2 = 40.6)被公开为最具选择性的PARP-2抑制剂,对日期。化合物11a的结合特征 分别研究了PARP-1和PARP-2中的CPA内含子,以为进一步利用CDOCKER程序构建PARP-1和PARP-2的同工型选择性抑制剂提供有用的见解。
