Herein, we report a photoswitchable modulator for a nuclear hormone receptor that exerts its hormonal effects in a light-dependent fashion. The azobenzene AzoGW enables optical control of the farnesoid X receptor (FXR), a key regulator of hepatic bile aci

Nonalcoholic steatohepatitis (NASH) is considered as severe hepatic manifestation of the metabolic syndrome and has alarming global prevalence. The ligand-activated transcription factors farnesoid X receptor (FXR) and peroxisome proliferator-activated receptor (PPAR) δhave been validated as molecular targets to counter NASH. To achieve robust therapeutic efficacy in this multifactorial pathology, combined peripheral PPAR?-mediated activity and hepatic effects of FXR activation appear as a promising multitarget approach. We have designed a minimal dual FXR/PPARδactivator scaffold by rational fusion of pharmacophores derived from selective agonists. Our dual agonist lead compound exhibited weak agonism on FXR and PPARδand was structurally refined to a potent and balanced FXR/PPARδactivator in a computer-aided fashion. The resulting dual FXR/PPARδmodulator comprises high selectivity over related nuclear receptors and activates the two target transcription factors in native cellular settings.

Our group has previously reported a series of isoflavone derivatives with antidyslipidemic activity. With this background, a series of isoflavone analogs of GW4064 were designed, synthesized and evaluated the lipid-lowering activity of analogs. As a result, most of compounds significantly reduced the lipid accumulation in 3T3-L1 adipocytes and four of them (10a, 11, 15c and 15d) showed stronger inhibitory than GW4064. The most potent compound 15d exhibited promising agonistic activity for FXR in a cell-based luciferase reporter assay. Meanwhile, 15d up-regulated FXR, SHP and BSEP gene expression and down-regulated the mRNA expression of lipogenesis gene SREBP-1c. Besides, an improved safety profile of 15d was also observed in a HepG2 cytotoxicity assay compared with GW4064. The obtained biological results were further confirmed by a molecular docking study showing that 15d fitted well in the binding pocket of FXR and interacted with some key residues simultaneously.
