Product Data:
Biological target: Benfluorex is a hepatic nuclear factor 4 alpha (HNF4α) activator.
In vitro activity: Benfluorex had an inhibitory activity on the incorporation of 14C-acetate and of 14C-HMG-CoA into non-saponifiable lipids in human blood mononuclear cells incubated in lipid-deficient medium. The lack of effect on the incorporation of 14C-mevalonate into non-saponifiable lipids strongly suggested that the reduction of sterol biosynthesis was mainly due to the inhibition of HMG-CoA reductase activity. Reference: Drugs Exp Clin Res. 1986;12(11):923-7. https://pubmed.ncbi.nlm.nih.gov/3816510/
In vivo activity: The effect of chronic (20 days) oral administration of benfluorex (35 mg/kg) in a rat model of NIDDM, induced by injection of STZ 5 days after birth and characterized by frank hyperglycemia, hypoinsulinemia, and hepatic and peripheral insulin resistance, was examined. Basal blood glucose and insulin levels, glucose tolerance and glucose-induced insulin release in vivo, and basal and insulin-stimulated in vivo glucose production and glucose utilization were examined. In the benfluorex-treated diabetic rats, postabsorptive basal plasma glucose levels were decreased (8.1 +/- 0.2 mM compared with 10.5 +/- 0.5 mM in the pair-fed untreated diabetic rats and 6.1 +/- 0.2 mM in the benfluorex-treated nondiabetic rats), whereas the basal and glucose-stimulated intravenous glucose tolerance test plasma insulin levels were not improved. In the pair-fed untreated diabetic rats, the basal glucose production and overall glucose utilization were significantly increased. In the benfluorex-treated diabetic rats, the basal glucose production and basal overall glucose utilization were normalized. After hyperinsulinemia, glucose production was normally suppressed, whereas overall glucose utilization was not significantly improved.
