of the boronic acid derivatives of tyropeptin, a proteasome inhibitor, was studied. Based on the structure of a previously reported boronate analog of tyropeptin (2), 41 derivatives, which have varying substructure at the N-terminal acyl moiety and P2 position, were synthesized. Among them, 3-phenoxyphenylacetamide 6 and 3-fluoro picolinamide 22 displayed the most potent inhibitory activity toward
研究了蛋白酶体抑制剂tyropeptin的硼酸衍生物的结构-活性关系。基于先前报道的酪肽素(2)的硼酸酯类似物的结构,合成了在N-末端酰基部分和P2位置具有不同亚结构的41种衍生物。其中3-苯氧基苯基乙酰胺6和3-氟吡啶甲酰胺22分别对蛋白酶体的胰凝乳蛋白酶活性和细胞毒性表现出最强的抑制活性。将P2侧链中的异丙基替换为H或Me对本研究中检测到的生物学活性的影响可忽略不计。
