Selective and Potent Proteomimetic Inhibitors of Intracellular Protein-Protein Interactions

摘要

Inhibition of protein-protein interactions (PPIs) represents a major challenge in chemical biology and drug discovery. -Helix mediated PPIs may be amenable to modulation using generic chemotypes, termed proteomimetics, which can be assembled in a modular manner to reproduce the vectoral presentation of key side chains found on a helical motif from one partner within the PPI. In this work, it is demonstrated that by using a library of N-alkylated aromatic oligoamide helix mimetics, potent helix mimetics which reproduce their biophysical binding selectivity in a cellular context can be identified.
