[PGH2_MOUSE] Mediates the formation of prostaglandins from arachidonate. May have a role as a major mediator of inflammation and/or a role for prostanoid signaling in activity-dependent plasticity.[1] [2] [3] [4]
Publication Abstract from PubMed
In this Letter, we provide the structure-activity relationships, optimization of design, testing criteria, and human half-life data for a series of selective COX-2 inhibitors. During the course of our structure-based drug design efforts, we discovered two distinct binding modes within the COX-2 active site for differently substituted members of this class. The challenge of a undesirably long human half-life for the first clinical candidate 1t(1/2)=360h was addressed by multiple strategies, leading to the discovery of 29b-(S) (SC-75416) with t(1/2)=34h.
