1,5-Regioisomeric triazole linked disaccharides have been synthesized and screened for their inhibitory properties against ribonuclease A (RNase A). The angular constraint-driven ‘crescent shaped’ inhibitors accommodated themselves into the enzyme active site. An improved enzyme inhibition was observed with increased H-bonding ability of polar functional groups in the modified disaccharides. In this
已经合成了1,5-区域异构的三唑连接的二糖,并筛选了它们对核糖核酸酶A(RNase A)的抑制特性。角度约束驱动的“新月形”抑制剂使其自身进入酶活性位点。在修饰的二糖中观察到改善的酶抑制作用以及极性官能团的H键结合能力增强。在该系列中,在呋喃糖环中引入两个羧基可产生最佳结果,其抑制常数为50±3 µM。这是关于使用二糖作为RNase A抑制剂的首次报道。
