GW4064

GW4064, as a synthetic FXR agonist, was used for treatment of cholestatic liver diseases, metabolic syndrome and alcoholic liver disease.^[1]

In vitro experiment it shown that the IC50 values of GW4064 in SW620 and HT-29 cells were 7.6 μM and 13.8 μM, respectively.^[2] In vitro efficacy test it indicated that the GW4064 response was concentration dependent (EC50 values after 24 hours of treatment were 0.012 μM and 0.015 μM, respectively) on CRE and NFAT-RE luciferases.^[3] GW4064 dose dependently enhanced the basal cAMP level with EC50 of 0.241 μM, and suppressed forskolin-induced cAMP accumulation with IC50 of 0.07 μM.^[3]

In vivo study it demonstrated that Rats in the treatment group received an interperitoneal GW4064 injection of 30 mg/kg every other day for 2 wk, GW4064 could correct BA dysmetabolism to alleviate hepatotoxicity in SBR animals. In the meanwhile, GW4064 intervention decreased the fecal bile excretion and elevated plasma/hepatic conjugated BA levels. It also increased the reabsorption of conjugated BAs by inducing apical sodium-dependent bile salt transporter expression in the ileum.^[4] In vivo, treatment with 30 mg/kg for 7 consecutive days intraperitoneally, GW4064 alleviated social deficits in BTBR mice and modulated selective aspects of the composition of the gut microbiota.^[5] Mice were injected 20 mg/kg GW4064 intraperitoneally result in that decreased hepatic inflammation in the LPS-induced murine liver injury model.^[6].
