lead discovery of DL0805, a new ROCK I inhibitor, showing potent inhibitory activity (IC50 6.7 μM). Herein, we present the lead optimization of compound DL0805, resulting in the discovery of 24- and 39-fold more-active analogues 4a (IC50 0.27 μM) and 4b (IC50 0.17 μM), among other active analogues. Moreover, ex-vivo studies demonstrated that 4a and 4b exhibited comparable vasorelaxant activity to the
Rho激酶(ROCK)抑制剂在多种疾病(例如高血压,中风,哮喘和青光眼)中具有潜在的治疗适用性。在上一篇文章中,我们描述了新型ROCK I抑制剂DL0805的先导发现,它显示出强大的抑制活性(IC50 6.7μM)。在本文中,我们介绍了化合物DL0805的前导优化,从而发现了24倍和39倍活性更高的类似物4a(IC50 0.27μM)和4b(IC50 0.17μM)。此外,离体研究表明,在大鼠主动脉环中,4a和4b的血管舒张活性与批准的法舒地尔相当。
