has been closely linked to cancer. Selectiveinhibitors of this enzyme are lacking. Inspired by DNA lesions produced by antitumor agents that inactivate Pol β, we have undertaken the development of covalent small-molecule inhibitors of this enzyme. Using a two-stage process involving chemically synthesized libraries, we identified a potent irreversible inhibitor (14) of Pol β (KI = 1.8 ± 0.45 μM, kinact
DNA 聚合酶 β (Pol β) 在 DNA 修复中起着至关重要的作用,并且与癌症密切相关。缺乏这种酶的选择性抑制剂。受使 Pol β 失活的抗肿瘤剂产生的 DNA 损伤的启发,我们着手开发这种酶的共价小分子抑制剂。使用涉及化学合成文库的两阶段过程,我们确定了Pol β的有效不可逆抑制剂 ( 14 ) ( K I = 1.8 ± 0.45 μM, k inact = (7.0 ± 1.0) × 10 –3 s –1 )。抑制剂14比其他 DNA 聚合酶选择性地灭活 Pol β。用14处理的 Pol β 胰蛋白酶消化物的 LC-MS/MS 分析鉴定了聚合酶结合位点内共价修饰的两个赖氨酸,其中一个先前被确定在DNA结合中起作用。荧光各向异性实验表明,用14预处理 Pol β可防止 DNA 结合。在野生型小鼠胚胎成纤维细胞 (MEF) 中使用前抑制剂 ( pro - 14 ) 的实验表明,抑制剂
