serpins and all classes of mammalian immunoglobulins. The application of specific and potent inhibitors of V8 protease may lead to the development of new antibacterial agents. Herein, we present the synthesis and the inhibitory properties of novel peptidyl derivatives of a phosphonic glutamic acid analogue. One of the compounds Boc-Phe-Leu-GluP(OC6H4)2 displayed an apparent second-order inhibition
内切蛋白酶GluC(V8蛋白酶)是金黄色葡萄球菌在体内释放的许多毒力因子之一。V8蛋白酶能够水解某些丝氨酸蛋白酶抑制剂和所有种类的哺乳动物免疫球蛋白。V8蛋白酶的特异性和有效抑制剂的应用可能导致新的抗菌剂的开发。在本文中,我们介绍了膦谷氨酸类似物的新型肽基衍生物的合成和抑制性能。化合物Boc-Phe-Leu-Glu P(OC 6 H 4)2之一显示出明显的二阶抑制率值为8540 M -1 s -1。Boc-Phe-Leu-Glu P(OC 6具有最高抑制能力的H 4)2化合物具有在体外预防V8介导的人IgG蛋白水解的能力。
