The design, synthesis, and conformational analysis of an oligobenzanilide helix mimetic scaffold capable of simultaneous mimicry of two faces of an α-helix is reported. The synthetic methodology provides access to diverse monomer building blocks amenable to solid-phase assembly in just four synthetic steps. The conformational flexibility of model dimers was investigated using a combination of solid
报道了能够同时模仿α-螺旋的两个面的寡苯甲酰苯胺螺旋模拟支架的设计,合成和构象分析。合成方法仅需四个合成步骤即可提供适用于固相组装的多种单体结构单元。使用补充了DFT计算的固态和溶液态方法相结合,研究了模型二聚体的构象灵活性。缺乏非共价约束的支架允许在构架中显着的构象可塑性,从而使其能够成功地模仿规范α-螺旋的残基i,i + 2,i + 4,i + 6,i + 7和i + 9。
