Biological Activity

Description Amlodipine (UK-48340) is a long-acting calcium channel blocker, used to lower blood pressure and prevent chest pain.
Calcium channel [1]
In vitro

Amlodipine causes a dose-dependent increase in nitrite production. Amlodipine also increases nitrite production in large coronary arteries and in aorta. [1] Amlodipine is attributed to distinct membrane physico-chemical interactions. Amlodipine contributes to distinct membrane biophysical interactions that lead to potent lipid antioxidant effects, independent of calcium channel modulation. [2] Amlodipine increases plaque smooth muscle cell content (P<0.05), whereas atenolol decreases plaque inflammation. [3] Amlodipine attenuates intracellular neuronal Ca2+ increases elicited by KCl depolarization but does not affect Ca2+ changes triggered by N-methyl-D-aspartate receptor activation. Amlodipine also inhibits free radical-induced damage to lipid constituents of the membrane in a dose-dependent manner, independent of Ca2+ channel modulation. [4]

In vivo Amlodipine results in regression of cardiovascular hypertrophy and amelioration of endothelial dysfunction in spontaneously hypertensive rats. [5] Amlodipine significantly reduces aortic hypertrophy, endothelial dysfunction, LOX-1 expression, aortic O(2)(-) and ONOO(-) production, and plasma free 8-F(2)alpha-isoprostane levels in Ang II-infused rats. Amlodipine has antihypertensive and antioxidant activity in vivo, which effectively inhibits many of the oxidative stress-dependent mechanisms involved in Ang II-mediated cardiovascular injury. [6]

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.
