Recent efforts to identify new highly potent arginase inhibitors have resulted in the discovery of a novel family of (3R,4S)-3-amino-4-(3-boronopropyl)pyrrolidine-3-carboxylic acid analogues with up to a 1000-fold increase in potency relative to the current standards, 2-amino-6-boronohexanoic acid (ABH) and N-hydroxy-nor-l-arginine (nor-NOHA). The lead candidate, with an N-2-amino-3-phenylpropyl substituent
最近鉴定新的高效精氨酸酶抑制剂的努力导致发现了新的(3R,4S)-3-氨基-4-(3-硼丙基)吡咯烷-3-羧酸类似物家族,其最高可达1000倍相对于当前标准的2-氨基-6-硼己酸(ABH)和N-羟基-正-1-精氨酸(nor-NOHA),其效力有所提高。具有N-2-氨基-3-苯基丙基取代基(NED-3238)的先导候选物,实施例43,抑制精氨酸酶I和II,IC 50值分别为1.3和8.1nM。在本文中,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,以及与人精氨酸酶II结合的所选实例的X射线晶体学数据。
