Abstract
In order to mimic amphipathic α-helices, a novel scaffold based on a 1,2-diphenylacetylene was designed. NMR and computational modeling confirmed that an intramolecular hydrogen bond favors conformations of the 1,2-diphenylacetylene that allow for accurate mimicry of the i, i + 7 and i + 2, i + 5 side chains found on opposing faces of an α-helix.
摘要
为了模拟两亲性的α-螺旋，设计了一种基于 1,2-二苯基乙炔的新型支架。NMR 和计算建模证实，分子内氢键有利于 1,2-二苯基乙炔构象的形成，从而可以准确模拟α-螺旋相对面上 i, i + 7 和 i + 2, i + 5 侧链。
