Bioorg Med Chem Lett. 2010 Apr 15;20(8):2658-64. doi: 10.1016/j.bmcl.2010.02.028. Epub 2010 Feb 25.

Abstract

A series of novel 1,7-disubstituted oxyindoles were shown to be potent and selective EP(3) 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, EP(1), EP(2) and EP(4). These agents also featured low CYP inhibition and good activity in the functional rat platelet aggregation assay.
