We describe the synthesis and biological activities of a series of methyl 3,4-epoxypiperidine-3-carboxylate tripeptide derivatives that inhibit the chymotryptic and tryptic active sites of the 20S proteasome. Of the series, compound 2 which contains 3-hydroxy-2-methylbenzoyl group at its N-terminal position, displayed the greatest inhibitory potency (IC(50) <1 microM). All derivatives showed favourable
我们描述了一系列3,4-环氧哌啶-3-羧酸甲酯三肽衍生物的合成和生物活性,这些衍生物抑制20S蛋白酶体的胰凝乳和胰蛋白酶活性位点。在该系列中,化合物2在其N端位置含有3-羟基-2-甲基苯甲酰基,显示出最大的抑制效能(IC(50)<1 microM)。所有衍生物均显示出良好的药代动力学性质。
