Crystal structure of COX-2 with selective compound 23d-(R)Crystal structure of COX-2 with selective compound 23d-(R)

Structural highlights

3ntg is a 4 chain structure with sequence from Lk3 transgenic mice. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:, , ,
Gene:Cox-2, Cox2, mCG_5001, Pghs-b, Ptgs2, Tis10 (LK3 transgenic mice)
Activity:Prostaglandin-endoperoxide synthase, with EC number 1.14.99.1
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

[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.

The novel benzopyran class of selective cyclooxygenase-2 inhibitors.
