چکیده

The present work reports the study of the antimicrobial activity of four quinoxaline N,N-dioxide: quinoxaline 1,4-dioxide, 2-methylquinoxaline 1,4-dioxide, 6chloro-2,3-dimethylquinoxaline 1,4-dioxide and 3-benzoyl-2-methylquinoxaline 1,4dioxide against Geobacillus stearothermophilus ATCC 10149, Escherichia coli ATCC 25922, Escherichia coli HB101, Escherichia coli (blaTEM, blaCTX-M) and Salmonella (blaCTX-M) bacterial strains and also against the yeast Saccharomyces cerevisiae PYCC 4072. The determination of the minimal inhibitory concentration (MIC) was performed by the dilution method. The MIC values were estimated for each compound and each microorganism. The results obtained suggest potential new drugs for antimicrobial chemotherapy.

A QSAR Study of 2-carboxamide-1,4-di-N-oxide quinoxaline Derivatives

A set of density functional theory (DFT) calculations were performed on 2-carboxamide-1,4- di-N-oxide quinoxaline (2CdNOQ) derivatives. The optimized structure of these compounds in three forms was obtained. Some electronic parameters including dipole moment (μ),ionization potential (I), electron af finity (A), LUMO energy (εLUMO), HOMO energy (εHOMO),electronegativity (χ), hardness (η), ele...

Esters of Quinoxaline 1,4-di-N-oxide with Cytotoxic Activity on Tumor Cell Lines Based on NCI-60 Panel

Quinoxalines display diverse and interesting pharmacological activities as antibacterial, antiviral, antiparasitic and anticancer agents. Particularly, their 1,4-di-N-oxides derivatives have proved to be cytotoxic agents that are active under hypoxic conditions as that of solid tumours. A new series of quinoxaline 1,4-di-N-oxides substitutes at 7-position with esters group were synthetized and ...
