novel series of highly potent α,α-disubstituted amino acid-based arginase inhibitors. The lead candidate, (R)-2-amino-6-borono-2-(2-(piperidin-1-yl)ethyl)hexanoic acid, compound 9, inhibits human arginases I and II with IC50s of 223 and 509 nM, respectively, and is active in a recombinant cellular assay overexpressing human arginase I (CHO cells). It is 28% orally bioavailable and significantly reduces
最近为确定心肌缺血再灌注损伤的治疗方法所做的努力导致发现了一系列新型的高效α,α-二取代氨基酸基精氨酸酶抑制剂。主要候选化合物(R)-2-氨基-6-硼烷-2-(2-(哌啶-1-基)乙基)己酸化合物9抑制人精氨酸酶I和II的IC 50分别为223nM和509nM,并且在过表达人精氨酸酶I(CHO细胞)的重组细胞测定中有活性。它具有28%的口服生物利用度,可显着减少心肌缺血/再灌注损伤大鼠模型中的梗塞面积。本文中,我们报告了该新型抑制剂系列的设计,合成和结构活性关系(SAR),以及化合物9的药代动力学和体内功效数据,以及与精氨酸酶I和II共结晶的所选先导化合物的X射线晶体学数据。
