| In vitro |
Aspirin inhibits the activation of NF-kappa B, thus prevents the degradation of the NF-kappa B inhibitor, I kappa B, and therefore NF-kappa B is retained in the cytosol. Aspirin also inhibits NF-kappa B-dependent transcription from the Ig kappa enhancer and the human immunodeficiency virus (HIV) long terminal repeat (LTR) in transfected T cells. [1] Aspirin and salicylate are mediated in part by their specific inhibition of IKK-beta, thereby preventing activation by NF-kappaB of genes involved in the pathogenesis of the inflammatory response. [2] Aspirin is protective against neurotoxicity elicited by the excitatory amino acid glutamate in rat primary neuronal cultures and hippocampal slices. [3] Aspirin triggers transcellular biosynthesis of a previously unrecognized class of eicosanoidsduring coincubations of human umbilical vein endothelial cells (HUVEC) and neutrophils [polymorphonuclear leukocytes (PMN)]. Aspirin evokes a unique class of eicosanoids formed by acetylated PGHS-2 and 5-lipoxygenase interactions. [4] Aspirin treatment inhibits the phosphorylation of IRS-1 at Ser307 as well as the phosphorylation of JNK, c-Jun, and degradation of IkappaBalpha in 3T3-L1 and Hep G2 cells treated with tumor necrosis factor (TNF)-alpha. Aspirin treatment inhibits phosphorylation of Akt and the mammalian target of rapamycin (but not extracellular regulated kinase or PKCzeta) in response to TNF-alpha. Aspirin rescues insulin-induced glucose uptake in 3T3-L1 adipocytes pretreated with TNF-alpha. [5] |

Bio Calculators
Molarity Calculator
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).
Dilution Calculator
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.
