Scientific background
Darusentan, (LU 135252), is a synthetic compound that acts as a selective antagonist of endothelin A (ET-A) receptors. Darusentan is orally bioavailable and is a potent inhibitor of vasoconstriction in large and small arteries. The compound is a propanoic acid based antagonist that consist of two enantiomers - (R) and (S). The (R) enantiomer shows no binding activity, indicating that the (S) enantiomer is the active drug1,2.in vitro, Darusentan inhibits endothelin-induced vascular contractility in isolated endothelium-denuded rat aortic rings with pA2 value of 8.11,2.Endothelin receptors include two subtypes: ET-A and ET-B. They are widely distributed in vascular and nonvascular tissues. ET-A receptors are predominantly expressed in peripheral tissues, especially in vascular smooth muscle tissues to mediate vasoconstriction. They are also detected in several different regions of the brain3.
