Inhibitors of type I MetAPs containing pyridine-2-carboxylic acid thiazol-2-ylamide. Part 2: SAR studies on the pyridine ring 3-substituent
摘要:
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. (C) 2004 Elsevier Ltd. All rights reserved.
Discovery and Structural Modification of Inhibitors of Methionine Aminopeptidases from Escherichia coli and Saccharomyces cerevisiae
摘要:
A series of pyridine-2-carboxylic acid derivatives were synthesized according to the leads from the screening, and potent inhibitors have been obtained by structural modification. They have shown submicromolar inhibition of the enzymes (for example, for 9n, IC50 = 130 nM for EcMetAP1 and IC50 = 380 nM for ScMetAP1). They represent small-molecule MetAP inhibitors with novel structures different from alkylating fumagillin derivatives and peptidic bestatin-based MetAP inhibitor.
