Biological Activity

Description

Olmesartan Medoxomil (CS-866,RNH-6270) is a selective angiotensin II type 1 (AT(1)) receptor antagonist, used in the treatment of high blood pressure.

Targets

AT1 receptor ^[1]

In vitro
In vitro	Olmesartan Medoxomil significantly reduces liver hydroxyproline content, the mRNA expression of collagen alpha1(I) and alpha-smooth muscle actin (alpha-SMA), and plasma levels of transforming growth factor-beta1 (TGF-beta1). ^[1] Olmesartan Medoxomil is a pro-drug containing an ester moiety that, after oral administration, is rapidly cleaved to release the active form Olmesartan (RNH-6270). Olmesartan is a highly potent, competitive and selective All AT1 receptor antagonist with almost no antagonistic activity on AT2 and AT4 receptors. ^[2]

In Vivo
In vivo	Olmesartan produces a rapid and long-lasting inhibition of All-induced pressor responses in conscious rats. Oralolmesartan medoxomil also inhibits All-pressor response but onset of the action is slower compared with intravenous administration. Olmesartan Medoxomil exhibits dose-dependent antihypertensive effects in several rat and dog models, with the most marked effects seen in high plasma renin models, when compared with normal or low renin types. Olmesartan medoxomil exhibits, beside antihypertensive effects, beneficial effects in animal models of various types of nephrosis and heart failure, and anti-atherogenic effects in hyperlipidaemic animals. ^[2] Olmesartan Medoxomil dose-dependently ameliorates the colonic histopathological and biochemical injuries in rats, an effect that is comparable or even better than that of the standard Sulfasalazine. ^[3] Olmesartan medoxomil significantly reduces the induction of hypoxic cor pulmonale not only on echocardiographical observations but also in brain natriuretic peptide (BNP) in chronic hypoxic rats, TGF-beta and endothelin gene expressions in molecular studies. ^[4]

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
