摘要 针对液相合成对羧基苯胺发色底物的不足,采用Boc-对羧基苯肼和MBHA树脂为原料合成了具有保险拉手型连接臂结构的树脂,对保护基形式及树脂载体类型的选择进行了探讨。基于该型树脂采用微波辅助的Fmoc/Boc混合策略在树脂上合成了5个用于丝氨酸蛋白酶活性实验的多肽中间体,经温和的N-溴代琥珀酰亚胺/吡啶条件氧化连接臂后,与对硝基苯胺(pNA)发生氨解反应,以较高的收率和纯度得到5个丝氨酸蛋白酶发色底物。中间体及产物经过高分辨质谱和核磁共振氢谱确定了结构。 N'-Phenylacylhydrazide safly-catch resin was syn- thesized by derlvatizing commercial available MBHA resin with N'-Boc-4-hydrazinobenzoic acid. N'-Protection form of 4- hydrazinobenzoic acid and initial amino functional resin type have been investigated to achieve higher derivation yield. Five serine protease peptidyl-pNA chromogenic substrates were synthesized with the safty-catch resin by Boc/Fmoc hybrid- ized protocol with high yields and purity. Intermediates and product were characterized by HRMS and NMR.
