Biological Activity

Tasosartan blocks the renin-angiotensin-aldosterone system (RAAS) at the level of the AT1 receptor that mediates most, if not all, of the important actions of Ang II. Tasosartan binds reversibly to the AT1 receptors in vascular smooth muscle and the adrenal gland. As angiotensin II is a vasoconstrictor, which also stimulates the synthesis and release of aldosterone, blockage of its effects results in decreases in systemic vascular resistance. AT1 receptor antagonists avoid the nonspecificity of the Ang I converting enzyme (ACE) inhibitors. Antagonism of the AT1 receptor with tasosartan reduces blood pressure at rest and during submaximal exercise but not during maximal exercise. The reduced blood pressure was associated with a reduced total peripheral resistance during submaximal exercise but not at rest in the control condition while cardiac output was unaltered in either condition. Lastly, tasosartan did not impair working capacity as measured from peak workload and oxygen uptake.

Method receptor binding assay
Cell Lines vascular smooth muscle cell
Incubation Time 4 to 6 h
Results In the receptor binding assay, the addition of 6.25% human plasma to the buffer (final concentration of plasma protein 0.4%) resulted in small but significant differences in the affinity of tasosartan for the AT1 receptor (IC50 shifted from 2.0 to 9.5 nM), whereas the same procedure shifted IC50 for enoltasosartan from 0.4 to 340 nM

Method oral administration

Concentrations 50 mg
Incubation Time 8.0 h
Results Tasosartan was rapidly absorbed after oral administration and Tmax 30 min (with Cmax of 1596 ± 250 ng/ml) was observed in all subjects (n=12).

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
