Structure-activity Relationship for FR901464: A Versatile Method for the Conversion and Preparation of Biologically Active Biotinylated Probes

Abstract
The structure-activity relationship for FR901464, a potent cell-cycle inhibitor, was examined by synthesizing its analogs. A versatile method for converting FR901464 was devised. This method made it possible to synthesize biologically active FR901464-biotin conjugates which could be used to isolate the binding proteins.
