Activated Fly Ash Catalyzing the Synthesis of Novel Potent 4-Thiazolidinones of 4-Amino Antipyrine Anils Using CEM Discover Microwave Methodology and Their Virtual Screening
waste, has been used as an efficient and cost-effective activating catalyst for the synthesis of new potent thiazolidinones (4a–n), starting from imine (3a–n) and thioacetic acid. The reactions were performed under CEM Discover microwave irradiation in solvent-free conditions. This reaction is scalable to a multigram scale and the methodology has resulted in an efficient synthesis. Herein, a benign
摘要 飞灰是一种工业废物,已被用作一种高效且具有成本效益的活化催化剂,用于以亚胺 (3a-n) 和硫代乙酸为原料合成新型强效噻唑烷酮 (4a-n)。反应在无溶剂条件下在 CEM Discover 微波辐射下进行。该反应可扩展到数克规模,并且该方法产生了有效的合成。在此,已经证明了一种用于合成噻唑烷酮的良性、环境友好、高效和极快的方法。基于元素分析、红外 (IR)、质谱和 1 H NMR 光谱数据表征所产生的噻唑烷酮分子。对合成的部分进行了虚拟筛选并讨论了它们可能的生物活性。图形概要
Characterization of Antimicrobial, Antioxidant, and Leishmanicidal Activities of Schiff Base Derivatives of 4-Aminoantipyrine
work, we have synthesized 12 Schiffbasederivatives of 4-aminoantipyrine. In vitro antimicrobial, antioxidant, and cytotoxicity properties are analyzed, as well as in silico predictive adsorption, distribution, metabolism, and excretion (ADME) and bioactivity scores. Results identify two potential Schiff bases: one effective against E. faecalis and the other with antioxidant activity. Both have reasonable

The thermalbehaviour of all the compounds was studied by non-isothermal chemiluminescence in static air atmosphere at different heating rates. The pattern of the oxidation process is described. Moreover, thermo-gravimetric and differential scanning calorimetry experiments were conducted in order to assess the thermal oxidation stability. The onset oxidation temperatures show a high thermal stability

Abstract A series of nine complexes of uranylnitrate with some Schiff bases derived from 4-aminoantipyrine and certain carbonyl compounds, such as benzaldehyde, 2-nitrobenzaldehyde, 3-nitrobenzaldehyde, 4- methylbenzaldehyde, 4- N , N -dimethylaminobenzaldehyde, 2-hydroxybenzaldehyde, 2-hydroxy-1-naphthaldehyde, acetylacetone and benzoylacetone have been synthesized. These complexes have been characterized
摘要硝酸铀酰与4-氨基安替比林和某些羰基化合物(例如苯甲醛,2-硝基苯甲醛,3-硝基苯甲醛,4-甲基苯甲醛,4-N,N-二甲基氨基苯甲醛,2-羟基苯甲醛)衍生的席夫碱形成的九种络合物合成了2-羟基-1-萘醛,乙酰丙酮和苯甲酰基丙酮。这些配合物已通过元素分析,分子量测定以及红外光谱,电导和磁学研究进行了表征。从这些研究中,它们可以公式化为[UO 2 L 2(NO 3)2],其中前五个配体(按上面给出的顺序)和硝酸根离子进行二齿配位,而后四个配体(要么具有酚羟基或侧链羰基作为额外的位点)充当三齿配体,硝酸根离子是单齿配位的。因此,所建议的配合物通式表明,除了已经与U(VI)物种键合的两个氧原子以外,铀酰离子的配位数为8。
