Losartan Carboxylic Acid, also named E-3174, a physiologically active metabolite of losartan, is a non-peptide, potent angiotensin II (AII) receptor, type 1 (AT1) antagonist, which inhibits the AII induced cellular responses. AII is the primary mediator of the reninangiotensin system, which regulates the blood pressure and body-fluid balance and may be associated with the development of cardiovascular diseases via increasing contractility and cell growth in vascular smooth muscle cells (VSMC).
In vitro: E-3174 potently blocked the specific binding of [125I]-AII to VSMC isolated from rat aorta. E-3174 was able to dampen the platelet-derived growth factor-induced increase in cell DNA synthesis and protein, which led to the blockade of the AII-induced increase in cell protein [1].
In vivo: Rats were administrated E-3174 intravenously at a dose of l.0 mg/kg. After 6 hours, E-3174 markedly attenuated the cardiovascular effects of AII in rats. E-3174 induced a progressive fall in mean arterial pressure and a marked increase in renal flow only [2].
