Biological Activity

Description 5-Acetylsalicylic acid (5-acetyl-2-hydroxybenzoic acid) is a nonsteroidal anti-inflammatory drug.
In vitro
In vitro 5-Acetylsalicylic acid (5-ASA) is initially shown to downregulate the inducible cyclooxygenase/prostaglandin E2 (COX-2/PGE2) signalling in mucosa inflammatory cells. Generally 5-ASA decreases the nuclear factor κB (NF-κB) activity induced by TNF-α, modulating the NF-κB inhibitor, IκBα, as well as the NF-κB transcriptional activity induced by IL-1, although it does prevent neither IL-1-induced IκBα degradation nor IL-1-induced nuclear translocation of NF-κB family members. 5-ASA is also found to increase β-catenin expression/phosphorylation and the expression of μ-protocadherin in intestine cells while reducing the expression of Wnt/β-catenin target genes and the activity of the protein phosphatase 2A. 5-ASA enhances PPAR-γ expression/activity in intestine cells and promotes its translocation from the cytoplasm to the nucleus -- this is followed by the induction of the tumour suppressor gene PTEN, the activation of caspases 8 and 3, and the inhibition of antiapoptotic proteins. It induces membranous expression of E-cadherin and increases cell adhesion through inhibition of p-21 activated kinase-1 and modulation of N-glycosylation; Also interferes with the mitogen activated protein kinase and phosphatidylinositol-4,5-bisphosphate 3-kinase/Akt pathways[1].
In Vivo
In vivo 5-ASA is rapidly adsorbed and extensively acetylated to N-acetyl-5-ASA by the N-acetyltransferase 1 enzyme in intestinal epithelial cells and the liver. It is generally well tolerated and the most common side effects include headache, nausea, and abdominal pain[1].

Working concentration: mg/ml;

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.
