SR 1903 is a modulator of retinoic acid receptor-related orphan receptor γ (RORγ) and liver X receptor (LXR).1 It is an inverse agonist of RORγ (IC50 = ~100 nM in a cell-based reporter assay) and an agonist of LXR. It also binds to peroxisome proliferator-activated receptor γ (PPARγ; IC50 = 209 nM) but does not activate it. SR 1903 (10 μM) inhibits LPS-induced expression of triggering receptor expressed on myeloid cells 1 (TREM-1) in RAW 264.7 cells. It also inhibits LPS-induced expression of the LXR target genes IL-6 and IL-33 and increases expression of ABCG1, FASN, and SCD-1 in RAW 264.7 cells. SR 1903 (20 mg/kg twice per day) reduces severity score in a mouse model of collagen-induced arthritis. It reduces blood glucose levels in a glucose tolerance test, serum levels of total cholesterol and LDL, body weight, and fat mass in a mouse model of high-fat diet-induced obesity.References1.

ZLY032 is a dual agonist of free fatty acid receptor 1 (FFAR1/GPR40; EC50= 68 nM in a FLIPR assay) and peroxisome proliferator-activated receptor δ (PPARδ; EC50= 102 nM in a reporter assay).1It is selective for FFAR1 and PPARδ over PPARα and PPARγ (EC50s = >10 μM for both). ZLY032 (40 mg/kg, twice per day) reduces blood glucose levels in an oral glucose tolerance test and decreases plasma total cholesterol and triglyceride levels in theob/obmouse model of metabolic disease.2It reduces hepatic steatosis and plasma alanine transaminase (ALT) and aspartate aminotransferase (AST) levels in a mouse model of non-alcoholic steatohepatitis (NASH) induced by a methionine and choline-deficient diet at the same dose.

Pioglitazone potassium (U 72107) is an orally active and selective agonist of peroxisome proliferator-activated receptor gamma (PPARγ). It demonstrates high affinity binding to the ligand-binding domain of PPARγ, with an EC50 of 0.93 μM and 0.99 μM for human and mouse PPARγ, respectively. Pioglitazone potassium has applications in diabetes research [2] [3] [4].
15-deoxy-Δ12,14-Prostaglandin D2 (15-deoxy-Δ12,14-PGD2) is a PGD2 metabolite functioning as an agonist for the PGD2 receptor 2 (DP2), with a binding affinity (Ki) of 50 nM for the mouse DP2 receptor expressed in HEK293 cell membranes. It activates eosinophils with an EC50 of 8 nM and enhances the recruitment of steroid receptor coactivator-1 (SRC-1) to peroxisome proliferator-activated receptor γ (PPARγ), initiating PPARγ-mediated transcription at 5 µM concentration. Furthermore, it exhibits cytotoxicity towards L1210 murine leukemia cells with an IC50 of 0.3 µg/ml and displays weaker inhibition of ADP-induced platelet aggregation than PGD2, with an IC50 of 320 ng/ml.
