| | Losartan carboxylic acid Usage And Synthesis |
| Description | Losartan carboxylic acid is a physiologically active metabolite of losartan , produced by cytochrome P450 isoforms in the liver. Like the parent compound, losartan carboxylic acid is a potent AT1 antagonist (Kis = 0.57 and 0.67 nM for rat and human forms, respectively), producing a depressor response and vasodilatation. When administered intravenously, losartan carboxylic acid is more potent and has a longer duration of action than losartan. However, the metabolite has very low oral bioavailability. Losartan, but not its metabolite, inhibits platelet aggregation in vitro. | | Chemical Properties | Light-Yellow Solid | | Uses | Losartan carboxylic acid is used as a metabolite of Losartan. | | Definition | ChEBI: A biphenylyltetrazole that is losartan with the hydroxymethyl group at position 5 on the imidazole ring replaced with a carboxylic acid. | | 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]. | | storage | Store at -20°C | | references | [1]. li, x. & widdop, r. angiotensin type i receptor antagonists cy-11974 and exp 3174 cause selective renal vasodilatation in conscious spontaneously hypertensive rats. clinical science, 1996; 91(2): 147-154.
