The quinoxaline unit in the title mol-ecule, CHNO, is slightly puckered [dihedral angle between the rings = 2.07 (12)°] while the whole mol-ecule adopts an L-shaped conformation. Intra-molecular hydrogen bonding determines the orientation of the substituted phenyl ring and the amide nitro-gen atom is almost planar. The packing in the crystal is governed by C-H⋯O hydrogen bonds and slipped π-stacking inter-actions.

Computational Evaluation of Fusarium nygamai Compounds as AcrD Efflux Pump Protein Inhibitors of Salmonella Typhimurium.
Mol Biotechnol

Department of Biotechnology, University of Mianwali, Punjab, 42200, Pakistan.
In Salmonella Typhimurium, efflux pump proteins, such as AcrD actively expel drugs and hazardous chemicals from bacterial cells, resulting in treatment failure and the emergence of antibiotic-resistant variants. Focusing on AcrD may lead to the development of novel antimicrobials against multidrug-resistant bacteria. However, challenges persist in achieving high selectivity, low toxicity, and effective bacterial penetration.

Phosphorylated small molecule metabolites play crucial roles in physiological processes such as glycogen metabolism and inflammation regulation. However, their high polarity, structural similarity, poor chromatographic separation, and weak mass spectrometric signals make their accurate quantification challenging, thereby hindering the study of related metabolic mechanisms and diseases. To address these challenges, we developed a novel derivatization reagent, DMQX (5-diazomethane quinoxaline), and combined it with liquid chromatography-mass spectrometry (LC-MS).

Cell Death Dis

Intestinal cell death is a defining feature of Crohn's disease (CD), a major form of inflammatory bowel disease. The focus on this aspect of enteric inflammation has mainly been on epithelial cells, while other cell types such as stromal and myeloid cells have received less attention. Hypothesising that decreased macrophage viability in an oxidative environment could be a contributing factor to the pathophysiology of CD, we found that monocyte-derived macrophages from individuals with active CD (but not those in clinical disease remission) have increased sensitivity to cell death induced by HO.

Skeletal editing represents an attractive strategy for adding complexity to a given molecular scaffold in chemical synthesis. Isodesmic reactions provide a complementary skeletal editing approach for the redistribution of chemical bonds in chemical synthesis. However, catalytic enantioselective isodesmic reaction is extremely scarce and enantioselective isodesmic reaction to synthesize atropisomeric compounds is unknown.
