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...
متن کاملSynthesis and biological evaluation of quinoxaline di-N-oxide derivatives with in vitro trypanocidal activity.
We report the synthesis and in vitro activity against Trypanosoma cruzi epimastigotes of 15 novel quinoxaline derivatives. Ten of the derivatives presented IC50 values lower than the reference drugs Nfx and Bzn; four of them standed out with IC50 values lower than 1.5 μM. Moreover, unspecific cytotoxicity and genotoxicity studies are also reported. Compound 14 showed a SI higher than 24, wherea...
متن کاملIn silico studies of quinoxaline-2-carboxamide 1,4-di-n-oxide derivatives as antimycobacterial agents.
Molecular modelling studies were performed on some previously reported novel quinoxaline-2-carboxamide 1,4-di-N-oxide derivatives (series 1-9). Using the LigandScout program, a pharmacophore model was developed to further optimize the antimycobacterial activity of this series of compounds. Using the Dock6 program, docking studies were performed in order to investigate the mode of binding of the...
متن کاملEfficacy of quinoxaline-2-carboxylate 1,4-di-N-oxide derivatives in experimental tuberculosis.
This study extends earlier reports regarding the in vitro efficacies of the 1,4-di-N-oxide quinoxaline derivatives against Mycobacterium tuberculosis and has led to the discovery of a derivative with in vivo efficacy in the mouse model of tuberculosis. Quinoxaline-2-carboxylate 1,4-di-N-oxide derivatives were tested in vitro against a broad panel of single-drug-resistant M. tuberculosis strains...
