Clear solution
Saline
30.0mg/ml Taking the 1 mL working solution as an example, add 30 mg of this product to 1 ml of physiological saline (0.9% NaCL solution), mix evenly to make it clear, The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Losartan Potassium is an angiotensin II receptor antagonist, competes with the binding of angiotensin II to AT1 receptors with IC50 of 20 nM.
Targets
AT1 receptor [1]
20 nM
In vivo Losartan (180 mg/d) causes significant increases in plasma angiotensin II and angiotensin-(1-7) in monkeys with diet-induced hypercholesterolemia. Losartan (180 mg/d) reduces the extent of fatty streak in the aorta, the coronary arteries, and the carotid arteries by approximately 50% in monkeys with diet-induced hypercholesterolemia. Losartan reduces the susceptibility of LDL to in vitro oxidation, serum levels of monocyte chemoattractant protein-1, and circulating monocyte CD11b expression in monkeys with diet-induced hypercholesterolemia. [2] Losartan (0.6 g/L in their drinking water) prevents elastic fiber fragmentation and blunted TGF-β signaling in the aortic media in pregnant Fbn1C1039G/+ mice, as evidenced by reduced nuclear accumulation of pSmad2. Losartan (0.6 g/L in their drinking water) shows a reduction in distal airspace caliber in pregnant Fbn1C1039G/+ mice. Losartan (0.6 g/L in their drinking water) improves disease manifestations in the lungs, an event that cannot plausibly relate to improved hemodynamics in pregnant Fbn1C1039G/+ mice. [3] Losartan (5 mg/kg/d) leads to a significant decrease in the development of atherosclerotic lesions in the apo E deficient mice. Losartan (5 mg/kg/d) significantly reduces the susceptibility of the mice LDL to lipid oxidation following its incubation with CuSO4 in the apo E deficient mice. [4] Losartan (10 mg/kg) administration increases blood angiotensin levels four fold to six fold, blood BK levels are unchanged in male Sprague Dawley rats. Losartan (10 mg/kg) increases plasma renin levels 100-fold, plasma angiotensinogen levels decreases to 24% of control and plasma aldosterone levels are unchanged in male Sprague Dawley rats. [5]
Features Losartan has a major active metabolite, EXP 3174.
