Generic approaches for the design and synthesis of small molecule inhibitors of proteinâprotein interactions (PPIs) represent a key objective in modern chemical biology. Within this context, the α-helix mediated PPIs have received considerable attention as targets for inhibition using small molecules, foldamers and proteomimetics. This manuscript describes a novel N-alkylated aromatic oligoamide proteomimetic scaffold and its solid-phase synthesisâthe first time such an approach has been used for proteomimetics. The utility of these scaffolds as proteomimetics is exemplified through the identification of potent μM inhibitors of the p53âhDM2 helix mediated PPIâa key oncogenic target.

α-Helix mediated protein–protein interactions are of major therapeutic importance. As such, the design of inhibitors of this class of interaction is of significant interest. We present methodology to modify N-alkylated aromatic oligoamideα-helixmimetics using ‘click’ chemistry. The effect is shown to modulate the binding properties of a series of selective p53/hDM2 inhibitors.
α-螺旋介导的蛋白质-蛋白质相互作用具有重要的治疗意义。因此,此类相互作用的抑制剂的设计具有重要意义。我们提出了使用“点击”化学修饰N-烷基化芳香族低酰胺 α-螺旋模拟物的方法。该效应可调节一系列选择性 p53/ h DM2 抑制剂的结合特性。
aberrant conditions. α-Helixmimetics—small molecules that reproduce the spatial projection of key residues from an α-helix involved in a PPI—are attractive generic templates for development of screening libraries, however library syntheses of α-helixmimetics with diverse functionality are less established. This manuscript describes the automated, microwave assisted solid phase synthesis based on one such

In this work, it is demonstrated that by using a library of N‐alkylated aromatic oligoamide helixmimetics, potent helixmimetics which
