Losartan potassium

SKU: orb1226684

Description

A selective, competitive angiotensin II receptor type 1 (AT1) antagonist (IC50=20 nM) for treatment of high blood pressure (hypertension).Hypertension Approved(In Vitro):Losartan competes with the binding of angiotensin II to AT1 receptors. The concentration that inhibits 50% of the binding of angiotensin II (IC50) is 20 nM. Losartan (40 μM) affects ISC but prevents the effect of ANGII on ISC. Losartan significantly reduces Ang II-mediated cell proliferation in endometrial cancer cells. The combination of losartan and anti-miR-155 has a significantly greater antiproliferative effect compared to each drug alone.(In Vivo):Losartan (0.6 g/L, p.o.) -treated Fbn1C1039G/+ mice show a reduction in distal airspace caliber relative to placebo-treated Fbn1C1039G/+ animals. The doses of losartan and propranolol are titrated to achieve comparable hemodynamic effects. Analysis of pSmad2 nuclear staining reveals that losartan antagonizes TGF-β signaling in the aortic wall of Fbn1C1039G/+ mice. Losartan can improve disease manifestations in the lungs, an event that cannot plausibly relate to improved hemodynamics. Losartan (10 mg/kg, intraarterial injection) increases blood angiotensin levels four- to sixfold. Losartan (10 mg/kg, i.p.) increases plasma renin levels 100-fold; plasma angiotensinogen levels decreases to 24% of control; and plasma aldosterone levels are unchanged.
