Hydralazine impairs up-regulation of RAG-2 gene expression and reduces secondary Ig gene rearrangements. Hydralazine subverts B lymphocyte tolerance to self and contributes to generation of pathogenic autoreactivity by disrupting receptor editing.  Hydralazine directly scavenges free acrolein, decreasing intracellular acrolein availability and thereby suppressing macromolecular adduction. Hydralazine inhibits cross-linking if adding 30 min after commencing acrolein exposure but is ineffective if added after a 90-min delay.  Hydralazine (0.1-10 mM) inhibits both extracellular and intracellular ROS production by inflammatory macrophages, by a ROS-scavenging mechanism probably affecting superoxide radical (O(2)(*-))-generation by xanthine oxidase (XO) and nicotinamide adenine dinucleotide/nicotinamide adenine dinucleotide phosphate (NADH/NADPH) oxidase. Hydralazine (0.1-10 mM) significantly reduces NO(*) generation, and this effect is attributable to an inhibition of NOS-2 gene expression and protein synthesis. Hydralazine also effectively blocks COX-2 gene expression which perfectly correlated with a reduction of protein levels and PGE(2) synthesis.  Hydralazine protects against not only acrolein-mediated injury, but also compression in guinea pig spinal cord ex vivo. Hydralazine can significantly alleviate acrolein-induced superoxide production, glutathione depletion, mitochondrial dysfunction, loss of membrane integrity, and reduces compound action potential conduction. 
|In vivo||Hydralazine affords strong, dose-dependent protection against the increases in plasma marker enzymes but not the hepatic glutathione depletion produced by allyl alcohol in mice. |

* 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.
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 MSDS / 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 MSDS / 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.
