Synthesis and biological activity of a series of tetrasubstituted-imidazoles as P2X7 antagonists
摘要:
A series of analogues of the pyrazole lead 1 were synthesized in which the heterocyclic core was replaced with an imidazole. A number of potent antagonists were identified and structure-activity relationships (SAR) were investigated both with respect to activity at the P2X(7) receptor and in vitro metabolic stability. Compound 10 was identified as a potent P2X(7) antagonist with reduced in vitro metabolism and high solubility. (c) 2010 Elsevier Ltd. All rights reserved.
