pseudopeptide analogues without requirement of hydroxyphosphinyl protection. The title compounds appeared to be moderate inhibitors of the cathepsin C. However, although designed as transition state analogues, they surprisingly exhibited noncompetitive mode of binding to cathepsin C. Differences in kinetics of C-terminal acids and esters have been additionally observed.
膦三肽类似物Gly-Xaapsi [P(O)(OH)CH(2)]-Gly已开发为组织蛋白酶C(DPP I)(一种溶酶体,木瓜蛋白酶样半胱氨酸蛋白酶)的抑制剂。通过将丙烯酸甲酯添加到适当的次膦酸中,然后使用混合酸酐法进行N末端延伸,来合成目标化合物。已证明后面的步骤是用于次膦酸假肽类似物的N-末端延伸而不需要羟基次膦酰基保护的合适方法。标题化合物似乎是组织蛋白酶C的中度抑制剂。但是,尽管设计为过渡态类似物,但它们出人意料地表现出与组织蛋白酶C的非竞争性结合方式。另外还观察到了C末端酸和酯的动力学差异。
