an aza-scan of a potent, peptide-based PKB/Akt inhibitor, PTR6154. Procedures for microwave-assisted, Fmoc/t-Bu chemistry, solid-phase aza-peptide synthesis were developed which significantly reduce standard reaction time and are suitable for automation. Novel substituted hydrazines have been prepared for the straightforward incorporation of aza-arginine and aza-proline residues. This work will enable
氮杂肽是拟肽,其中带有侧链残基的一个或多个α-碳已被氮取代。这些拟肽被证明对药物前导的产生和结构活性关系的研究是有前途的。氮杂扫描是给定肽中的
