The EP(3) receptor on the platelet mediates prostaglandin E(2) potentiation of thrombogenic coagonists including collagen and adenosine diphosphate (ADP). A pharmacophore driven approach led to the identification of diverse peri-substituted heterocycles as potent and selective EP(3) receptor antagonists. A simultaneous chemical optimization and druglike assessment of prioritized molecules converged oil a lead compound 50 (DG-041) that displayed favorable in vitro and functional activities as an inhibitor of human platelet aggregation. This agent is currently in human clinical trials for the treatment of atherothrombosis.

A series of novel 1,7-disubstituted oxyindoles were shown to be potent and selective EP3 receptor antagonists. Variation of substitution pattern at the C-3 position of indole enhanced in vitro metabolic stability of the resulting derivatives. Series 27a-c showed >1000-fold selectivity over a panel of prostanoid receptors including IP, FP, EP1, EP2 and EP4. These agents also featured low CYP inhibition and good activity in the functional rat platelet aggregation assay. (C) 2010 Elsevier Ltd. All rights reserved.
