N-(Hydroxyaminocarbonyl)phenylalanine (1) was designed rationally as a new type of inhibitor for carboxypeptidase A (CPA). The designed inhibitor was readily prepared from phenylalnine benzyl ester in two steps and evaluated to find that rac-1 inhibits CPA in a competitive fashion with the Ki value of 2.09 microM. Surprisingly, inhibitor 1 having the D-configuration is more potent (Ki = 1.54 microM)
N-(羟基氨基羰基)苯丙氨酸(1)被合理设计为羧肽酶A(CPA)的新型抑制剂。设计的抑制剂可以很容易地从苯丙氨酸苄基酯分两步制备,并进行评估以发现rac-1以竞争性方式抑制CPA,Ki值为2.09 microM。令人惊讶地,具有D-构型的抑制剂1比其对映体更有效(Ki =1.54μM)约3倍。提出了在用1抑制CPA中观察到的立体化学的可能解释。
