Biological Activity

Description Telmisartan (BIBR 277) is an angiotensin II receptor antagonist (ARB) used in the management of hypertension.
angiotensin II receptor [1]
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.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
