| 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. Telmisartan induces adipocyte differentiation of 3T3-L1 cells. Telmisartan causes a 60% to 70% decrease in the expression of ACC2 in murine muscle myotubes. [1] Telmisartan, but not candesartan, another ARB, downregulates RAGE mRNA levels in a dose-dependent manner. Telmisartan decreases basal as well as AGE-induced RAGE protein expression in Hep3B cells. Telmisartan dose-dependently inhibits AGE-induced ROS generation and subsequent CRP gene and protein induction in Hep3B cells. [2] Telmisartan effectively facilitates differentiation of 3T3-L1 preadipocytes. Telmisartan 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. Telmisartan attenuates 11beta-hydroxysteroid dehydrogenase type 1 mRNA level in differentiated adipocytes. [3] |

| 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. Telmisartan 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.

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
