    生物活性

    Losartan potassium (DuP-753 potassium) is an angiotensin II receptor type 1 (AT1) antagonist, competing with the binding of angiotensin II to AT1 with an IC50 of 20 nM.

    AT1 Receptor

     

    体外研究
    (In Vitro)

    Losartan potassium 竞争血管紧张素 II 与 AT1 受体的结合。抑制 50% 血管紧张素 II 结合的浓度 (IC50) 为 20 nM[1]。Losartan potassium (40 μM) 影响 ISC 但阻止 ANGII 对 ISC 的影响[2]。Losartan potassium 显著降低子宫内膜癌细胞中 Ang II 介导的细胞增殖。与单独使用每种药物相比,Losartan potassium 和抗 miR-155 的组合具有显著更强的抗增殖作用[3]

    Losartan potassium (0.6 g/L,po) 处理的 Fbn1C1039G/+ 小鼠显示相对于安慰剂处理的 Fbn1C1039G 远端空域口径减少/+ 。滴定 Losartan potassium 和普萘洛尔的剂量以达到可比较的血液动力学效果。pSmad2 核染色分析表明,Losartan potassium 拮抗 Fbn1C1039G/+ 小鼠主动脉壁中的 TGF-β 信号传导。Losartan potassium 可以改善肺部的疾病表现,这一事件与改善的血流动力学似乎无关[4]。Losartan potassium (10 mg/kg,动脉内注射) 使血液血管紧张素水平增加四到六倍。Losartan potassium (10 mg/kg,ip) 使血浆肾素水平增加 100 倍;血浆血管紧张素原水平降至对照的 24%;和血浆醛固酮水平没有变化[5]

    Cell Assay
    [3]

    An MTT assay is used to measure cell proliferation and viability. For the assay, 5000 cells in 200 μL 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 1 mg/mL concentration in serum-free medium is added and then incubated for 4 h at 37°C. After removal of MTT solution, 100 μL of DMSO is added to dissolve formazan crystals. Absorbance at 570 nm and at 600 nm as a reference is then measured using a microplate reader. The difference in absorbance is thus relative to the extent of cell survival.

    Animal Administration
    [4]

    Female Fbn1C1039G/+ mice undergo timed matings with wild-type male mice. At 14.5d post-coitum, pregnant female Fbn1C1039G/+ mice are treated with oral losartan (0.6 g/L in drinking water; n=10), propranolol (0.5 g/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 (0.6 g/L in drinking water; n=5), propranolol (0.5 g/L; n=7) or placebo (n=10). Mice are continued on oral therapy for 6 months and then sacrificed.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
