Cơ Chế Tác Dụng :
PS433540 is the first and only dual-acting angiotensin and endothelin receptor antagonist (DARA) in development. The study showed all doses of PS433540 compared with placebo produced a statistically significant inhibition of the expected angiotensin (AII) induced increase in blood pressure.
The compound, which possesses two clinically validated mechanisms of action in a single molecule, works by selectively blocking the action of two potent vasoconstrictor and mitogenic agents, angiotensin II (AII) and endothelin 1 (ET1), at their respective receptors. PS433540 is highly selective (10,000-fold) for the AII receptor sub-type 1 and the ET receptor sub-type A. As such, PS433540 combines the properties of an angiotensin receptor blocker (ARB) and an endothelin receptor antagonist (ERA) in the same molecule.
