Abstract
Systematic SAR studies on the pyridine ring 3-substituent of PCAT, an inhibitor of EcMetAP1 and ScMetAP1, revealed that 3-substituents have different selectivity for EcMetAP1 and ScMetAP1. The selective inhibitors of type I MetAP are useful tools for investigating the detailed interactions between the enzymes and their inhibitors. In addition, these findings provide useful information for the design and discovery of more potent inhibitors of type I MetAPs.
