New Advances in Chemical Research, May 2021. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. Computed Properties of C8H4Cl2N2, In a article, mentioned the application of 2213-63-0, Name is 2,3-Dichloroquinoxaline, molecular formula is C8H4Cl2N2
A series of quinoxalinone derivatives were synthesized by the reaction of o-phenylenediamine with oxalic acid to yield 1, 4-dihydro quinoxaline-2, 3-dione (1) and then treated with thionyl chloride to yield 2, 3 dichloro quinoxaline (2). This was further reacted with hydrazine hydrate to produce 2, 3-dihydrazinyl quinoxaline (3). This was finally reacted with substituted aromatic aldehydes to produce 2,3-bis[2-(sustituted benzylidine) hydrazinyl] quinoxalines (4). These quinoxalinone derivatives were characterized by infrared spectroscopy and nuclear magnetic resonance spectroscopy and MASS spectral data. All the synthesized compounds were evaluated for their antimicrobial activity. The results of the antimicrobial study revealed that compounds 4c, 4d, and 4i were active and exhibited better inhibitory activities as compared to standard drug ciprofloxacin. The results were further checked with protein legend interaction by using docking studies, and all the compounds exhibited good docking scores between ?8.72 and ?11.29 kcal/mol against dihydrofolate reductase protein fragment from Staphylococcus aureus (PDB ID-4XE6). Among all compound, 4c has shown maximum docking score and found in agreement to in vitro studies.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2213-63-0, help many people in the next few years.Computed Properties of C8H4Cl2N2
