Efforts to re. ne the SAR of the piperazinyl-glutamate-pyridines for more potent analogs with improved pharmacokinetic profiles are described. Exploring substituted piperidines and other ring systems at the 4-pyridyl position led to compounds with improved potency and pharmacokinetic properties over candidate I. In particular, compounds 4t and 5t were discovered with a 10-fold improvement over potency and improved pharmacokinetic profiles in both the rat and dog. (C) 2010 Elsevier Ltd. All rights reserved.
