Description

T0901317 is a potent, high affinity liver X receptor (LXR) agonist. 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. T0901317 decreases amyloid-β production in primary neurons in vitro. T0901317 also exhibits inverse agonist activity at constitutive androstane receptors (CAR). Although T0901317 is a much more potent activator of LXR than FXR, this ligand actually activates FXR more potently than a natural bile acid FXR ligand, chenodeoxycholic acid. T0901317 treatment of 11-week-old APP23 mice for 6 days showed a significant increase in ABCA1 expression and a decrease in the ratio of soluble APP (sAPP)beta- to sAPPalpha-cleavage products. T0901317 decreases amyloidogenic processing of APP in vitro and in vivo, thus supporting the search for potent and specific LXR ligands with properties allowing therapeutic application.
