common chemical tool to control the conformation of linear peptides and to explore potentially useful effects on their biochemical and biophysical properties. The thioamide, psi[CS-NH], group is a nearly isosteric structural mimic of the amide (peptide) functionality. In this paper, we describe the solution synthesis, chemical characterization, preferred conformation, and membrane and biological activities
骨架修饰是一种常用的化学工具,用于控制线性肽的构象,并探索对其生化和生物物理特性的潜在有用影响。硫代酰胺 psi[CS-NH] 基团是酰胺(肽)功能的近等排结构模拟物。在本文中,我们描述了三种精心挑选的脂肽生物 [Leu(11)-OMe] 毛虫素 GA IV 的肽类似物的溶液合成、化学表征、优选构象以及膜和生物活性。在每个类似物中,加入了一个单一的硫代酰胺置换。研究了靠近 N 端、中心和靠近 C 端的序列位置。
