Synthetic methods for the construction of a novel peptidomimetic structure are reported. The structure incorporates a beta-lactam and an azapeptide in a peptide backbone with the intention of generating rationally designed substrate-based protease inhibitors. The beta-lactam is formed by subjecting serine or threonine-azapeptides to Mitsunobu reaction conditions. Importantly, the azapeptidomimetic
报道了用于构建新型拟肽结构的合成方法。该结构在肽主链中掺入了β-内酰胺和氮杂肽,目的是生成合理设计的基于底物的蛋白酶抑制剂。通过使丝氨酸或苏氨酸-氮杂肽经受Mitsunobu反应条件来形成β-内酰胺。重要的是,氮杂肽模拟物β-内酰胺结构允许扩展的结合抑制,并且描述了产生四肽模拟物结构的合成方法。
