Overview

Replacement Information
Description
OverviewA 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.

DescriptionA 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), inhibiting AR (aldose reductase) only at higher concentrations (IC50 = 172 nM) and exhibiting much reduced potency against PGD2 receptor DP1 (Ki = 1.58 µM; IC50 = 10 µM), PGE receptor EP2 (54% binding inhibition at 10 µM), and little or no activity toward 49 other receptors and ion channels (IC50 >10 µM). 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 (3.1- and 5.8-fold of control, respectively, with or without 30 mg/kg oral dosages 1 h before and 7 h after each of three daily 30-min OVA aerosol challenges) in vivo with good oral bioavailability (t1/2 = 3.9; AUC = 3730 ng·h/mL; 5 mg/kg p.o.).
