2-Thiazolidinecarboxamide, 3-([1,1'-biphenyl]-4-ylsulfonyl)-N-[(R)-phenyl-2-pyridinylmethyl]-, (2S)-

AS604872 is a small molecule selective antagonist of the FP receptor in inhibition of spontaneous uterine contraction. AS604872 significantly accelerated degeneration of the media in both cerebral artery and aorta as evidenced by thinning of the media and disruption of the elastic lamina and promoted IA and aortic dissection. AS604872 can be used to make models of these vascular diseases with extensive degeneration.
