New peptidic compounds, having peptide chains linked to bi- and tricyclic heterocycles (peptide-heterocycle hybrids), have been synthesized. The heterocyclic components are derivatives of partially reduced isoquinoline and pyrido[1,2-b]isoquinoline bearing α,β-unsaturated carbonyl functionalities. The heterocyclic compounds have been used as acylating agents in coupling reactions with short N-unprotected
已经合成了具有连接至双环和三环杂环的肽链的新肽化合物(肽-杂环杂化物)。杂环成分是具有α,β-不饱和羰基官能团的部分还原的异喹啉和吡啶并[1,2- b ]异喹啉的衍生物。在与短的N-未保护的肽的偶联反应中,杂环化合物已被用作酰化剂。基于我们对潜在钙蛋白酶抑制剂的兴趣,我们使用了具有两个对映异构系列疏水性氨基酸的短肽(2-4个氨基酸)。我们报告了对钙蛋白酶抑制的初步研究,其中一些化合物的IC 50值在纳摩尔范围内。
