The (R) enantiomer of a cell-permeable alkynylphenoxyacetic acid that acts as a high affinity antagonist against the G protein-coupled PGD2 receptor CRTH2/DP2 (Ki = 5.3 and 5.0nM 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 = 100nM). Exhibits higher Caco-2 permeability than DP2 Antagonist I, but less oral bioavailability in mice.
