Unlabelled: We have developed novel and sustainable homogeneous catalysts employing Glutamic acid (Glu) as a biodegradable and eco-friendly organocatalyst for the synthesis of -(4-oxo-2-phenyl-1,2-dihydroquinazolin-3(4)-yl)isonicotinamide derivatives (-) via multicomponent reactions (MCRs) of isatoic anhydride, isoniazid and heteroaromatic/aromatic aldehyde in ethanol on oil bath stirring at 60 °C. Selected final product homogeneity was examined by various spectroscopic techniques such as C-, H- NMR, FT-IR and LC-MS. For the first time, herein investigated electrochemical behavior of selected derivatives (-) using cyclic voltammetry method.

Exposure to low doses of antibiotics in organisms may have long-term effects on host growth and brain neurochemicals, which are achieved by disrupting the composition and metabolism of gut flora. Therefore, we should pay more attention to the use and management of antibiotics to protect human health and the ecological environment. Here, we developed a method of detecting 50 antibiotic residues simultaneously in human plasma using HPLC-MS/MS.

Ammonium decamolybdate (NH)[MoO] was used as a catalyst. From previous oligoesters, monodisperse species of monomers, dimers, and trimers were isolated by flash column chromatography (FCC).

The cell-free supernatant of (LCFS) is considered a potential natural antimicrobial agent due to its outstanding antimicrobial activity. This study demonstrated that the cell-free supernatant of SHY96 (LCFS96) effectively inhibits the growth and biofilm formation of CMCC(B)54002 (_02) by reducing cell metabolic activity and damaging cell structure. Metabolomic analysis revealed that LCFS96 significantly altered 450 intracellular metabolites, affecting key metabolic pathways including linoleic acid metabolism, pyrimidine metabolism, purine metabolism, pantothenic acid and CoA biosynthesis, and the TCA cycle.
