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.

REGIOSELECTIVITY IN THE REACTION OF NITROQUINOXALINE-N-OXIDES WITH PHOSPHORYL CHLORIDE

6-nitro-, 2-methyl-6-nitro- and 2,3-dimethyl-6-nitroquinoxaline have been transformed into their N-oxides by MCPBA in chloroform; the nitro group orients the oxygen atom preferentially to nitrogen atom N1, but the N4:N1 selectivity is diminished in the methylated derivatives.Under the action of POCl3 (the Meisenheimer reaction), the N-oxides of the unmethylated compounds are transformed into chloro-nitroquinoxalines having lost the N-oxide oxygen atom.The orientation of the entering chloride ion is discussed on the basis of electronic effects induced by the N-oxide and nitro groups, and it is suggested that the last step, the elimination of “HPO2Cl2” is a concerted process.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 6639-87-8

Living on pyrrolic foundations – Advances in natural and artificial bioactive pyrrole derivatives

Abstract Pyrrole, a simple heterocyclic system, is an important building block for numerous biologically active compounds both natural and synthetic in origin, which boast an immense array of qualities, baleful and beneficial alike. The latter have given rise to a bountiful variety of pyrrole-based drugs, with many more being designed, developed and applied each year, as evidenced by the amount of entries in the Cambridge Structural Database skyrocketing from about six hundred in 2004 to more than a thousand over the course of the last decade. Particularly important in light of the ever-encroaching menace of drug-resistant bacteria, the vast progress in the field necessitates a sound organisational framework and summary – a task, to which we contribute this summary and checklist of the most recent developments, indicating the classes of compounds, which have attracted the most significant research attention.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of 2,3-Dichloroquinoxaline, you can also check out more blogs about2213-63-0
