|Overview||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 = 2.0 and 2.4 nM against 1.5 nM PGD2 for human & murine DP2 binding, respectively), exhibiting much reduced potency against DP1 (Ki = 1.58 µM; IC50 = 10 µM), PGE receptor EP2 (54% inhibition at 10 µM), and little or no activity toward 49 other receptors and ion channels. Effectively inhibits PGD2-induced cellular activation (IC50 = 32 and 80 nM, respectively, using CHO-CRTH2 or human whole blood) in vitro and is efficacious in alleviating airway eosinophil infiltration in OVA- (Cat. No. 32467) sensitized mice (30 mg/kg; p.o.) in vivo with good oral bioavailability.|
