Structure-based design and synthesis of 2-benzylidene-benzofuran-3-ones as flavopiridol mimics.
Novel 2-benzylidene-benzofuran-3-ones were designed and synthesized to mimic flavopiridol, a well-established inhibitor of cyclin-dependent kinases (CDKs) which is currently undergoing clinical evaluation. The underlying design concepts as well as the synthesis and structure-activity relationships (CDKs 1, 2, and 4 enzyme assays) of these mimics are described. Inhibitors of CDKs 1 and 2 that are more potent and selective than flavopiridol were obtained.
