Characterization of Synthesized Heterocyclic Oxadiazole Derivatives Using Mass, UV, IR, and NMR Spectroscopy, Among other Spectroscopic Techniques: Review
Abstract: The current study synthesized and assessed 3-heteroarylazo 4-hydroxy coumarin derivatives' initial antibacterial activities in vitro against four distinct pathogenic bacterial strains, including Pseudomonas aeruginosa, Bacillus subtilis, Escherichia coli, and Staphylococcus aureus. Ampicillin, a common medication, was used to compare each compound's antibacterial properties. UV, IR, 1H NMR, mass spectroscopy, and X-ray diffraction examinations were used to analyze the compounds. By using UV–vis spectra, the solute-chromic behavior of these compounds was …

Non-Enzymatic Glycation in Alzheimer’s and Parkinson’s Disease: A Molecular Approach to Pathology and Recent Advances
Abstract: Non-enzymatic glycation, a biochemical process by which reducing sugars spontaneously bind to proteins, leads to the formation of advanced glycation end-products (AGEs), which have emerged as critical contributors to the pathogenesis of several neurodegenerative diseases, particularly Alzheimer’s disease (AD) and Parkinson’s disease (PD). The accumulation of AGEs can significantly alter protein structure, stability, and function, triggering a cascade of detrimental effects, including increased oxidative stress, heightened neuroinflammation, and the promotion …

Production of n-Butanol from Biomass by Two Step Fermentation Process Using Staphylococcus Sciuri
Abstract: This study explores the sustainable production of n-butanol from wheat husk through a two-step bioconversion process. Wheat husk, an abundant agricultural residue, was first fermented into butyric acid using Bacillus subtilis. The resultant butyric acid was then converted into n-butanol using Staphylococcus sciuri. The process leverages biological fermentation to create value-added chemicals from lignocellulosic biomass, offering an eco-friendly alternative to petrochemical methods. Two steps fermentation process were carried to increase …

An Efficient Synthesis of Some Novel Benzo Coumarin Derivatives Under Solvent Conditions from 2-acetyl-benzo[f]chromen-3-one
Abstract: The synthesis of the target compounds began with the preparation of 2-[3-dimethylamino[acryloyl-3H-benzo[f]chromen-3-one. This intermediate was obtained through the reaction of 2-acetylbenzo[f]coumarin-3-one with N,N-dimethylformamide dimethyl acetal [DMFDMA[ under reflux conditions in xylene. The enaminone thus formed was subsequently reacted with 6-aminothiouracil in acetic acid, leading to the formation of 2-thioxo-2,3-dihydro-1H-pyrido[2,3-d]pyrimidin-4-one. This compound served as a pivotal intermediate for the synthesis of a series of pyridotriazolopyrimidinones. These derivatives were synthesized by reacting …
