disrupting protein-protein interactions. Small organic molecules that target these less conserved regions might serve as tools for chemical biology research and to probe alternative strategies in targeting protein kinases in disease settings. Here, we present the structure-based design and synthesis of a focused library of 2-arylquinazoline derivatives to target the lipophilic C-terminal binding pocket
A chemical genetic approach is presented to covalentlytarget a unique lipid binding pocket in the protein kinase p38α, whose function is not yet known. Based on a series of cocrystal structures, a library of 2‐arylquinazolines that were decorated with electrophiles were designed and synthesized to covalentlytarget tailored p38αmutants containing artificially introduced cysteine residues.
