In an article, author is Bai, Xiaodong, once mentioned the application of 333-93-7, Product Details of 333-93-7, Name is 1,4-Diaminobutane dihydrochloride, molecular formula is C4H14Cl2N2, molecular weight is 161.0734, MDL number is MFCD00012526, category is amides-buliding-blocks. Now introduce a scientific discovery about this category.
The partial structure and immunology of the lipopolysaccharide (LPS) of Pseudomonas stutzeri KMM 226, a bacterium isolated from a seawater sample collected at a depth of 2000 m, was characterised. The O-polysaccharide was built up of disaccharide repeating units constituted by l-Rhap and d-GlcpNAc: -> 2)-alpha-l-Rhap-(1 -> 3)-alpha-d-GlcpNAc-(1 ->. The structural analysis of the lipid A showed a mixture of different species. The major species were hexa-acylated and penta-acylated lipids A, bearing the 12:0(3-OH) in amide linkage and 10:0(3-OH) in ester linkage, while the secondary fatty acids were present only as 12:0. The presence of 12:0(2-OH) was not detected. The immunology experiments demonstrated that P. stutzeri KMM 226 LPS displayed a low ability to induce TNF-alpha, IL-1 beta, IL-6, IL-8 and IL-10 cytokine production and acted as an antagonist of hexa-acylated Escherichia coli LPS in human blood in vitro.
