Abstract
Abstract We describe a medicinal chemistry approach for generating a series of 2-(1H- pyrazol-1-yl) thiazoles as EP 1 receptor antagonists. To improve the physicochemical properties of compound 1, we investigated its structure–activity relationships (SAR). Optimization of this lead compound provided small compound 25 which exhibited the best EP 1 receptor antagonist activity and a good SAR profile.
