Chemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter.305-84-0, Name is L-Carnosine, SMILES is OC([C@@H](NC(CCN)=O)CC1=CN=CN1)=O, belongs to amides-buliding-blocks compound. In a document, author is Hwang, Jinkwang, introduce the new discover, Quality Control of L-Carnosine.
Seven piperic acid amides along with their lower homologs (12) were synthesized using HATU-DIPEA coupling reagent. All the synthesized derivatives were evaluated for their antibacterial activities against Staphylococcus aureus, Pseudomonas aeruginosa, and vancomycin-resistant P. aeruginosa. They were found to be more active on P. aeruginosa than on S. aureus. However, they did not exhibit potent activity on Vancomycin resistant P. aeruginosa. Among the tested compounds, methylenedioxycinnamic acid amide of anthranilic acid (MDCA-AA, 2a) was found to be most active against S. aureus with MIC of 3.125 mu g/ml. The PAS and INH amides of piperic acid were screened against Mycobacterium tuberculosis H37R(a) strain. They were found to be most active among all the tested compounds but were found to be less active than the standard drug, isoniazid.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 305-84-0 is helpful to your research. Quality Control of L-Carnosine.
