This paper details the SAR of 1,5-biaryl pyrrole derivatives with substituents in the 2-, 4-, and 5-positions of the benzoic acid group as EP1 receptor antagonists. Substitution at the 2-position was poorly tolerated, whereas only fluorine was tolerated at the 4-position. In contrast, a range of substituents at the 5-position were discovered which enhanced the in vitro affinity and led to compounds
本文详细介绍了1,5-二芳基吡咯衍生物的SAR的苯甲酸基团的2-,4-和5-位上的取代基,作为EP1受体拮抗剂。在2-位的取代耐受性差,而在4-位仅耐受氟。相反,发现了5-位的一系列取代基,这些取代基增强了体外亲和力,并导致化合物具有良好的口服暴露性。当口服给大鼠时,三种衍生物在炎性疼痛的临床前模型中显示出功效。
