The discovery, proposed binding mode, and optimization of a novel class of Rho-kinase inhibitors are presented. Appropriate substitution on the 6-position of the azabenzimidazole core provided subnanomolar enzyme potency in vitro while dramatically improving selectivity over a panel of other kinases. Pharmacokinetic data was obtained for the most potent and selective examples and one (6n) has been shown to lower blood pressure in a rat model of hypertension.
本文介绍了一类新型Rho激酶抑制剂的发现、提出的结合模式及优化过程。在氮杂苯并咪唑核心结构的6位进行适当取代,可在体外提供亚纳摩尔级别的酶活性,同时显著提高对其他一系列激酶的选择性。已获得了最具活性和选择性的化合物的药代动力学数据,其中一种化合物(6n)已在高血压大鼠模型中显示出能降低血压的作用。
