A Fluorescence-Based Assay for p38α Recruitment Site Binders: Identification of Rooperol as a Novel p38α Kinase Inhibitor

A new p38α inhibitor: Using a D-recruitment site (DRS) probe for p38α which exploits covalent interaction with Cys119 and alkyne–azide “click” chemistry to identify small molecules that recognize the p38α DRS, the anti-inflammatory natural product rooperol was identified as a novel p38α inhibitor.
