To mimic amphiphilic α-helices, a new scaffold was designed based on a bis-benzamide that places four side-chain functional groups found at the i, i+2, i+5, and i+7 positions of a helix. Its two hydrogen bonds fix the conformation and provide accurate bifacial arrangement of the four substituents, simultaneously representing two opposing helical sides. An efficient synthetic route was achieved for
为了模拟两亲性的α-螺旋,基于双苯甲酰胺设计了一种新的支架,该支架将四个侧链官能团置于螺旋的i,i + 2,i + 5和i + 7位置。它的两个氢键固定构象并提供四个取代基的精确双面排列,同时代表两个相对的螺旋面。实现了双苯甲酰胺的有效合成途径,并通过X射线晶体学证实了其优异的α-螺旋模拟性。
