(2S)-2-Amino-4-(butylsulfonimidoyl)butanoic acid (BD136012) is a building block containing a sulfoximine group. Several CDK and ATR inhibitors have exemplified the utilization of the NH sulfoximine group as abioisostere for a sulfonamide group to overcome the main project hurdles of aqueous solubility, sulfonamide-mediated off-target activity and IP. Moreover, its NH group could be expediently further functionalized through Buchwald-Hartwig coupling reaction and multifarious nucleophilic reactions.. Recommended Products is: 4381-25-3 and 1621962-30-8.
The release of inflammatory cytokines from antigen-stimulated cells of the immune system is inhibited by resin monomers such as 2-hydroxyethyl methacrylate. Although the formation of oxidative stress in cells exposed to HEMA is firmly established, the mechanism behind the inhibited cytokine secretion is only partly known. The present investigation presents evidence regarding the role of HEMA-induced oxidative stress in the secretion of the pro-inflammatory cytokine TNF¦Á from cells exposed to the antigens LTA or LPS of cariogenic microorganisms using BSO or NAC to inhibit or stabilize the amounts of the antioxidant glutathione. RAW264.7 mouse macrophages were treated with LTA, LPS or HEMA in the presence of BSO or NAC for 1h or 24h. Secretion of TNF¦Á from cell cultures was analyzed by ELISA, and the formation of reactive oxygen or nitrogen species was determined by flow cytometry. Protein expression was detected by Western blotting. The release of TNF¦Á in both LTA- and LPS-exposed cells was decreased by HEMA, and this concentration-dependent inhibitory effect was amplified by BSO or NAC. LTA- and LPS-stimulated expression of the redox-sensitive transcription factor NF-¦ÁB (p65) in cell nuclei decreased in the presence of HEMA because the translocation of p65 from the cytosol was prevented by oxidative stress specifically increased by the monomer. A disturbance of the cellular redox balance, particularly induced by HEMA, is a crucial factor in the inhibition of LTA- and LPS-stimulated signalling pathways leading to TNF¦Á secretion.
HEMA-induced oxidative stress inhibits NF-¦ÊB nuclear translocation and TNF release from LTA- and LPS-stimulated immunocompetent cells. Recommended basis is Sulfoximine, Bioisosteric. Products is: https://www.ambeed.com/products/50578-18-2.html, 145026-07-9
