this N-terminal cyclic tripeptide could be readily incorporated into renin inhibitory peptides. Monte Carlo molecular modeling methods were used to generate bound conformations of a representative inhibitor in a model of the renin active site, suggesting possible modes of binding of these inhibitors to renin. Two representative compounds that contain this 14-membered macrocycle were evaluated for their
对作为肾素潜在抑制剂的构象约束肽的兴趣使我们研究了线性肾素抑制肽的N-末端循环。通过经由羧甲基片段将P4位点的N末端脯氨酸与P2位点的组氨酸的咪唑环连接,来制备环状结构。已经开发出一种有效的合成途径,可以合成14个成员的大环,并且该N端环状三肽可以很容易地掺入肾素抑制肽中。蒙特卡罗分子建模方法用于在肾素活性位点模型中产生代表性抑制剂的结合构象,表明这些抑制剂与肾素结合的可能模式。
