Helically folded aromatic oligoamide foldamers have a size and geometrical parameters very distinct from those of α‐helices and are not obvious candidates for α‐helix mimicry. Nevertheless, they offer multiple sites for attaching side chains. It was found that some arrays of side chains at the surface of an aromatic helix make it possible to mimic extended α‐helical surfaces. Synthetic methods were
螺旋折叠的芳香寡酰胺折叠体的尺寸和几何参数与α螺旋非常不同,并且不是α螺旋拟态的明显候选者。然而,它们提供了多个用于连接侧链的位点。研究发现,芳香螺旋表面的一些侧链阵列可以模拟延伸的 α 螺旋表面。开发了合成方法来生产适合固相合成的官能化喹啉单体。准备了十二角体。其晶体结构验证了最初的设计,并显示出涉及 α 螺旋样界面的螺旋成束。这些结果开辟了芳香螺旋识别蛋白质表面和编程水中螺旋捆绑的新用途。
