1,5-diaryl-2-alkylpyrrole-3-substituted nitro esters, of Formula (I)
are provided. Such compounds are potent and selective COX-2 inhibitors which are able to release NO in concentrations that make it possible to counteract the side effects due to selective COX-2 inhibition, without giving rise to hypotensive effects. Formula (I) includes compounds wherein the groups R′ and R″ are: —H, —F, —Cl, —Br, —CH
