A series of peptidyl vinyl ester derivatives bearing three different P1 substitutions as potential proteasome inhibitors were studied. The target molecules were designed based on CADD (computer aided drug design) protocol and synthesized. Their activities toward proteasome and four human cancer cell lines (including hepatoma cell line (Bel-7402), myeloid leukemic cell line (HL-60), gastric cancer cell
研究了一系列带有三个不同的P1取代基的肽基乙烯基酯衍生物,它们是潜在的蛋白酶体抑制剂。根据CADD(计算机辅助药物设计)协议设计目标分子并进行合成。它们对蛋白酶体和四种人类癌细胞系(包括肝癌细胞系(Bel-7402),髓样白血病细胞系(HL-60),胃癌细胞系(BGC-823)和鼻咽癌细胞系(KB))的活性为使用荧光测定法测试。两种化合物对蛋白酶体具有抑制活性,而四种化合物对HL-60和BGC-823的抗增殖活性较弱。
