T0901317S7076

T0901317 acts through LXR and in concert with its RXR heterodimerization partner induces the expression of the ABCA1 reverse cholesterol transporter. T0901317 upregulates expression of the ABCA1 gene associated with cholesterol efflux regulation and HDL metabolism.^[1] T0901317 displays an EC50 of ~ 5 μM for activation of bile acid farnesoid X receptors (FXRs), 10-fold more potent than natural FXR ligand chenodeoxycholic acid. ^[2] T0901317, is also a high-affinity ligand for the xenobiotic receptor pregnane X receptor (PXR). T0901317 binds and activates PXR with the same nanomolar potency with which it stimulates LXR activity. T0901317 induces expression not only of LXR target genes, but also of PXR target genes in cells and animals, including the scavenger receptor CD36. ^[3] T0901317 decreases amyloid-β production in primary neurons in vitro. ^[4] T0901317 is found to directly bind to RORα and RORγ with high affinity (Ki = 132 and 51 nM, respectively), resulting in the modulation of the receptor's ability to interact with transcriptional cofactor proteins. T0901317 represses RORα/γ-dependent transactivation of ROR-responsive reporter genes and in HepG2 cells reduces recruitment of steroid receptor coactivator-2 by RORα at an endogenous ROR target gene (G6Pase). ^[5]
