assays and fragment-based screening assisted by structure-guided design, we discovered a novel class of Rho-kinase inhibitors. Compound 18 was equipotent for ROCK1 (IC50 = 650 nM) and ROCK2 (IC50 = 670 nM), whereas compound 24 was more selective for ROCK2 (IC50 = 100 nM) over ROCK1 (IC50 = 1690 nM). The crystal structure of the compound 18–ROCK1 complex revealed that 18 is a type 1 inhibitor that binds
使用高浓度生化分析和基于片段的筛选,并辅以结构引导设计,我们发现了一类新的 Rho 激酶抑制剂。化合物18对 ROCK1 (IC 50 = 650 nM) 和 ROCK2 (IC 50 = 670 nM)具有同等效力,而化合物24对 ROCK2 (IC 50 = 100 nM) 的选择性高于 ROCK1 (IC 50 = 1690 nM)。化合物18 –ROCK1 复合物的晶体结构表明18是一种 1 型抑制剂,可结合 ATP 结合位点的铰链区。化合物18和24 有效抑制完整人乳腺癌细胞中 ROCK 底物 MLC2 的磷酸化。
