Abstract

Herein we describe the medicinal chemistry programme to identify a potential back-up compound to the EP1 receptor antagonist GW848687X. This work started with the lipophilic 1, 2-biaryl benzene derivative 4 which displayed molecular weight of 414.9 g/mol and poor in vivo metabolic stability in the rat and resulted in the identification of compound 7i (GSK345931A) which demonstrated good metabolic stability in the rat and lower ...
