SR-1903 is a modulator of retinoic acid receptor-related orphan receptor γ (RORγ) and liver X receptor (LXR). It is an inverse agonist of RORγ and an agonist of LXR. It also binds to peroxisome proliferator-activated receptor γ (PPAR) but does not activate it. SR-1903 inhibits LPS-induced expression of triggering receptor expressed on myeloid cells 1 (TREM-1). 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. SR-1903 reduces the severity 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.
SNU-BP is an agonist of PPAR-gamma, inhibiting lipopolysaccharide (LPS)-induced NO production and pro-inflammatory cytokines. SNU-BP potentiates interleukin-4-induced arginase-1 expression, and promotes microglial polarization toward an M2 anti-inflammatory phenotype.
Sitofibrate, a clofibrate derivative, acts as a peroxisome proliferator-activated receptor-α (PPAR-α) agonist and serves as an antihyperlipidemic agent [1].
