|Description||Amlodipine Besylate is a long-acting calcium channel blocker, used to lower blood pressure and prevent chest pain.|
Amlodipine besylate reduces the declines in p85aPI3K, phosphorylated Akt, phosphorylated GSK-3β, heat-shock transcription factor-1, and Bcl-2 induced by H(2) O(2) , as well as the increases in cyclooxygenase-2, cytosolic cytochrome c, cleaved caspase 9, and cleaved caspase 3 in neuronal cell. Amlodipine significantly reduces systolic blood pressure (SBP), 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 elicits an NO-mediated relaxation and a leftward shift in the concentration-relaxation curve to bradykinin in isolated, pre-contracted, endothelium-intact porcine coronary arteries. Amlodipine increases the generation of NO from native endothelial cells, as detected by electron spin resonance spectroscopy and stimulated an 8-fold increase in cyclic GMP levels in cultured endothelial cells. Amlodipine elicits the NO-mediated relaxation of rat aortic rings, which do not express the B2 receptor. Amlodipine time-dependently attenuates the phosphorylation of protein kinase C (PKC) in endothelial cells, with a time course similar to the changes in eNOS phosphorylation, and prevents the phorbol-12-myristate-13-acetate-induced activation of PKC. 
|In vivo||Amlodipine besylate significantly decreases average indirect systolic blood pressure measurements from 198 mmHg to 155 mmHg in the cats. Amlodipine besylate appears to be a safe and effective oral treatment for systemic hypertension in cats when used chronically once daily as a single agent. |
|In vitro||DMSO||113 mg/mL (199.27 mM)|
|Ethanol||14 mg/mL (24.68 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
2% DMSO+30% PEG 300+2% Tween 80+ddH2O
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
