|300266-2MG||Glass bottle||2 mg||
|Overview||The (R) enantiomer of a cell-permeable alkynylphenoxyacetic acid that acts as a high affinity antagonist against the G protein-coupled PGD2 (Cat. No. 538909) receptor CRTH2/DP2 (Ki = 5.3 and 5.0 nM against human & murine DP2, respectively), exhibiting much reduced potency against a panel of more than 50 other receptors and ion channels. Effectively inhibits DP2-dependent chemotaxis of primary human eosinophils (IC50 = 100 nM). Exhibits higher Caco-2 permeability than DP2 Antagonist I (Cat. No. 300264), but less oral bioavailability in mice.|
|Synonyms||(R)-(5-Chloro-1'-(5-chloro-2-fluorobenzyl)-2,2',5'-trioxospiro(indole-3,3→-pyrrolidin)-1(2H)-yl)acetic acid, CRTH2 Antagonist II, GPR44 Antagonist II|
