    Olmesartan (RNH-6270) is an angiotensin II receptor (AT1R) antagonist used to treat high blood pressure[1][2].

    In Vitro

    Olmesartan (0.7-5 mM; 24, 48 and 72 h) inhibits the growth of HeLa cells as a concentration- and time-dependent mode[3].

    Cell Viability Assay[3]

    Cell Line: Human cervical cancer cell line (HeLa)
    Concentration: 0.7- 5 mM
    Incubation Time: 24, 48 and 72 h
    Result: IC50s against HeLa cell line are 4.685 and 1.651 mM for 48 and 72 h, respectively.
    In Vivo

    Repeated dosing of olmesartan (1 mg/kg, 2 mg/kg, p.o.) dose-dependently decreases mean arterial blood pressure (MAP) in SHR without significant influence on body weight and food intake during 10 weeks[1]. Olmesartan (5 mg/kg/d, p.o.) and Hyd treatments lower systolic blood pressure to the same degree in mice. Olmesartan treatment inhibits cardiac hypertrophy, evaluated by echocardiography, heart weight, cross-sectional area of cardiomyocytes, and gene expression. Olmesartan treatment reverses decreased gene expressions of ACE2 and Mas receptor of Ren-Tg mice and inhibits enhanced NADPH oxidase (Nox)4 expression and reactive oxygen species[2].
