15-deoxy-Δ12,14-PGD2 is a metabolite of PGD2 . It is an agonist of PGD2 receptor 2 (DP2) that binds DP2 (Ki = 50 nM for the mouse receptor expressed in HEK293 cell membranes) and induces activation of eosinophils (EC50 = 8 nM). It also stimulates the recruitment of steroid receptor coactivator-1 (SRC-1) to peroxisome proliferator-activated receptor γ (PPARγ) and induces PPARγ-mediated transcription in a reporter assay when used at a concentration of 5 μM. 15-deoxy-Δ12,14-PGD2 is cytotoxic to L1210 murine leukemia cells (IC50 = 0.3 μg/ml). It inhibits ADP-induced platelet aggregation (IC50 = 320 ng/ml) less potently than PGD2.
15-deoxy-Δ12,14-Prostaglandin D2 (15-Deoxy-Δ12,14-PGD2), a metabolite of PGD2 (HY-101988), is an agonist of prostaglandin receptor 2 (DP2). 15-deoxy-Δ12,14-Prostaglandin D2 binds to DP2 (Ki=50 nM) and induces eosinophil activation (EC50=8 nM). 15-deoxy-Δ12,14-Prostaglandin D2 also stimulates the recruitment of steroid receptor coactivator-1 (SRC-1) to peroxisome proliferator-activated receptor γ (PPARγ), inducing PPARγ-mediated transcription. 15-deoxy-Δ12,14-Prostaglandin D2 (15-Deoxy-Δ12,14-PGD2) is cytotoxic to L1210 murine leukemia cells (IC50=0.3 μg/ml) and inhibits ADP-induced platelet aggregation (IC50=320 ng/mL).
