In the title compound, C39H38N4O8, the quinoxaline and indene subunits are essentially planar, with maximum deviations of 0.071 (2) and 0.009 (2) Å, respectively. The indeno-quinoxaline system forms a dihedral angle of 72.81 (3)° with the chromenopyrrolizine system. The two dioxolane rings, as well as the pyran ring of the chromeno group and the terminal pyrrolizine, each adopt an envelope conf...

The present work deals the structural and vibrational analysis of Quinoxaline molecule which is pharmaceutically and industrially important heterocyclic compound. The FTIR and FT-Raman spectra of Quinoxaline have been measured in the region of 0-3700 cm and UV-Visible spectrum also was recorded. The computations were carried out by employing DFT/B3LYP method with 6-311++G(d,p) basis set. The fi...

A series of Schiff bases such as 2-(substituted phenylimino) quinoxaline-3-one were synthesized by nucleophilic addition reaction of quinoxaline-2,3-dione with p-Phenylene diamine followed by the Schiff reaction using different aldehydes in alcholol. A total of five compounds were synthesized by both conventional and microwave oven method with good percentage yield. They were purified and chara...

3-Phenyl(methyl)-5-alkyl-1-(pyridin-3-yl)imidazo[1,5-a]quinoxalin-4-ones (2a-f) and their N-alkyl-pyridinium salts (3a-o), including 1,n-bis{3-(3-phenylimidazo[1,5-a]quinoxalin-4(5H)-on-1-yl)pyridinium}alkane dibromides (4a-d, 5, 6) have been synthesized. It has been established that the antimicrobial properties of imidazo[1,5-a]quinoxaline derivatives are connected with the presence of various...

As reported in our previous papers, a series of quinoxaline-2-carboxamide 1,4-di-N-oxide derivatives were synthesized and studied as anti-tuberculosis agents. Here, the capability of the shake-flask method was studied and the retention time (expressed as log K) of 20 compounds were determined by RP-HPLC analysis. We found that the prediction of log P by the RP-HPLC analysis can result in a high...

This prospective study, which conformed with good clinical practice (GCP-conform), tested the concept that the topical transtympanic administration of the quinoxaline derivative Caroverine promises a new approach to the treatment of tinnitus. The rationale for the study is the hypothesis that tinnitus reflects sequelae of auditory neurotoxicity that can prevented and repaired by the neuroprotec...

J. Phys. Or mochemical study of mono-N-oxides derived from quinoxaline, oxide and 3-ethoxycarbonyl-2-methyl-quinoxaline N-oxide. The values of the enthalpies of formation, in the condensed state, and of the enthalpies of sublimation, derived from static bomb calorimetry and Calvet microcalorimetry measurements, respectively, are combined to derive the standard molar enthalpies of formation in t...

The glucagon-like peptide 1 receptor (GLP-1R) is a member of the family (or class) B G-protein-coupled (GPCR). regulator insulin and key target in treating Type 2 diabetes mellitus. In this investigation, computational chemistry techniques such as molecular docking were combined with silico ADME/Tox predictions to determine position structure allosteric binding site, well examine how modulators...

(E)-Pyrrolo[1,2-a]quinoxalin-4-yl)-1-(3,4,5-trimethoxyphenyl)prop-2-en-1-one was designed then synthesized using a multi-step pathway starting from commercially available 2-nitroaniline. Structure characterization of this original substituted pyrrolo[1,2-a]quinoxaline compound achieved by FT-IR, 1H-NMR, 13C-NMR, X-Ray and HRMS spectral analysis. This new pyrroloquinoxaline shows interesting cyt...

Considering quinoxaline as a privileged structure for the design of potent intercalating agents, some new sugar conjugates of quinoxaline were synthesized and characterized by IR, (1)HNMR, (13)C NMR, and mass spectral data. In vitro testing for antitubercular and antimicrobial activities was performed against Mycobacterium tuberculosis H 37 Rv and some pathogenic bacteria. Results revealed that...
