      Description
      OverviewThe (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
      DescriptionThe (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 1.5 nM PGD2 for human & murine DP2 binding, respectively), exhibiting much reduced or little potency against a panel of more than 50 other receptors and ion channels, including PGD2 receptor DP1, PGE receptors (EP2, EP3, EP4), and PGF receptor FP (IC50 >30 µM). Effectively inhibits DP2-dependent chemotaxis of primary human eosinophils (IC50 = 100 nM; chemotractant = 100 nM DK-PGD2) in vitro. Shown to exhibit higher Caco-2 permeability than DP2 Antagonist I (Cat. No. 300264; Papp in unit of 10-6 cm/s = 26.4 vs. 5.2, respectively), but less oral bioavailability (32% in rat for Inhibitor II vs. 80% in mice for Inhibitor I with same oral dosage of 5 mg/kg).
