Biological Activity

Description Nifedipine (BAY-a-1040) is a dihydropyridine calcium channel blocker, used to lower hypertension and to treat angina.
calcium channel [1]
In vitro

Nifedipine causes a significant concentration-dependent increase in eNOS protein expression by cultured human coronary artery endothelial cells. [1] Nifedipine antagonizes L-type Ca+ channels found throughout the cardiovascular system, but also blocks Kv channels, which are members of the same supergene family. [2] Nifedipine dose-dependently decreases the values of [(3)H]-thymidine incorporation and total cellular protein content as well as the levels of phosphorylated extracellular signal-regulated protein kinase (ERK) 1/2, mitogen-activated protein kinase kinase (MEK) 1/2, and even the phosphorylation of Pyk2, in vascular smooth muscle cells (VSMC). Nifedipine suppresses the levels of proliferative cell nuclear antigen (PCNA) dose-dependently in both VSMC and balloon-injured thoracic aortae in VSMC. [3]

In vivo Nifedipine (3 mg/kg) slightly lowers the level of systolic and/or diastolic blood pressure or increased the heart rate in rats. [3] Nifedipine (1 μm) produces a maximal inhibition of the store-operated pathway in choroidal arteriolar smooth muscle. [4] Nifedipine (20 and 40 mg/kg) markedly prevents the HCl plus ethanol-induced gastric mucosal injury and the increase in the content of thiobarbituric acid-reactive substances in the injured mucosa in rats. Nifedipine (20 and 40 mg/kg) dose-dependently promotes the ulcer healing and inhibites the increase in the content of thiobarbituric acid-reactive substances in the ulcerated mucosa in rats. [5]

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.
