Reference of 2213-63-0, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 2213-63-0, molcular formula is C8H4Cl2N2, introducing its new discovery.
Synthesis of Novel Substituted Phenyl-3-Hydrazinyl-Quinoxaline-2-Amine Derivatives: Evaluation of Antimicrobial Activity and Its Molecular Docking Studies
New series of quinoxaline derivatives (4a?4h) were synthesized by treating 2-chloro-3-hydrazinyl quinoxalin (3) with various anilines. Compound 3 was obtained from the 2,3-dichloroquinoxaline 2 which was prepared from 4-dihydroquinoxaline-2,3-dione (1). All synthesized compounds (4a?4h) were characterized by various spectral techniques, that is, IR, 1H-NMR, mass spectroscopy, and elemental analysis and completion of reaction were confirmed by TLC. In vitro antimicrobial activity of synthesized compounds was evaluated using disc diffusion assay against gram-positive and gram-negative microbial strains, and then, the minimum inhibitory concentration and IC50 values of compounds were also determined. The results of antimicrobial study revealed that compounds 4e, 4g, and 4a were active and exhibited better inhibitory activities as compared with standard drug amoxicillin. Docking studies were performed by using Argus lab, and all the compounds exhibited good docking scores between ?9.53 and ?7.94?kcal/mol against dihydrofolate reductase protein fragment from Staphylococcus aureus (PDB ID-4XE6). Among all compounds, 4e has shown the maximum docking score and found in agreement to in vitro studies.
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 2213-63-0 is helpful to your research. Reference of 2213-63-0
