生物活性
产品描述 |
一种血管紧张素II受体1型(AT1)的一种有效的非肽类拮抗剂。这种受体启动一个信号级联,导致血管收缩。这种受体的拮抗作用通过阻断血管紧张素Ⅱ的信号而引起血管舒张。 |
靶点 |
IC50:20nM (angiotensin II) |
体外研究 |
Losartan competes with the binding of angiotensin II to AT1 receptors.The concentration that inhibits 50% of the binding of angiotensin II (IC50) is 20nM.Losartan (40μM) 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. |
体内研究 |
Losartan (0.6g/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 (10mg/kg,intraarterial injection) increases blood angiotensin levels four-to sixfold.Losartan (10mg/kg,i.p.) increases plasma renin levels 100-fold;plasma angiotensinogen levels decreases to 24% of control;and plasma aldosterone levels are unchanged. |
推荐实验方法(仅供参考)
细胞实验: |
|
An MTT assay is used to measure cell proliferation and viability.For the assay,5000 cells in 200μL media per well are seeded in a 96 well plate.After overnight incubation to allow for cell attachment,the medium is removed by suction.MTT at 1mg/mL concentration in serum-free medium is added and then incubated for 4h at 37℃.After removal of MTT solution,100μL of DMSO is added to dissolve formazan crystals.Absorbance at 570nm and at 600nm as a reference is then measured using a microplate reader.The difference in absorbance is thus relative to the extent of cell survival. |
动物实验: |
|
Female Fbn1C1039G/+mice undergo timed matings with wild-type male mice.At 14.5d post-coitum,pregnant female Fbn1 C1039G/+mice are treated with oral losartan (0.6g/L in drinking water;n=10),propranolol (0.5g/L;n=6) or placebo (n=12).Therapy is continued throughout lactation and after weaning until 10 months of age.Mice are sacrificed and examined using the techniques described above.Propranolol is used for comparison with losartan because β-adrenergic receptor blockade is the current albeit controversial standard of care to modulate abnormal growth of the aortic root in MFS.Beginning at 7 weeks of age,wild-type and Fbn1C1039G/+mice are treated with oral losartan (0.6g/L in drinking water;n=5),propranolol (0.5g/L;n=7) or placebo (n=10).Mice are continued on oral therapy for 6 months and then sacrificed. |
