Mechanism of Action

Targets/IC₅₀/Ki	angiotensin II receptor
In vitro	Telmisartan functions as a moderately potent (EC50=4.5 μM), selective PPARγ partial agonist, activating the receptor to 25% to 30% of the maximum level achieved by the full agonists pioglitazone and rosiglitazone. This compound induces adipocyte differentiation of 3T3-L1 cells. It causes a 60% to 70% decrease in the expression of ACC2 in murine muscle myotubes. This chemical, but not candesartan, another ARB, downregulates RAGE mRNA levels in a dose-dependent manner. It decreases basal as well as AGE-induced RAGE protein expression in Hep3B cells. This compound dose-dependently inhibits AGE-induced ROS generation and subsequent CRP gene and protein induction in Hep3B cells. It effectively facilitates differentiation of 3T3-L1 preadipocytes. This chemical causes a dose-dependent increase in mRNA levels for PPARgamma target genes such as aP2 and adiponectin in both differentiating adipocytes and fully differentiated adipocytes. It attenuates 11beta-hydroxysteroid dehydrogenase type 1 mRNA level in differentiated adipocytes.
In vivo	Telmisartan promotes increases in caloric expenditure and protects against dietary-induced weight gain in rats fed with a high-fat, high-carbohydrate diet. This compound reduces the accumulation of visceral fat and decreases adipocyte size to a much greater extent than valsartan and is also associated with a significant reduction in hepatic triglyceride levels in rats fed with a high-fat, high-carbohydrate diet.
