Synthesis, bioinformatics and biological evaluation of novel pyridine based on 8-hydroxyquinoline derivatives as antibacterial agents: DFT, molecular docking and ADME/T studies
discussed. The chemical and biological activities of hydroxyquinoline derivatives were compared with theoretical methods. The chemical activities of hydroxyquinoline derivatives were contrasted with the important quantum chemical parameters using the HF/6–31++g (d, p) basis sets. Besides, biological activities of hydroxyquinoline derivatives against cancer proteins that are respectively protein of the BRCT
本研究旨在首先探讨有机化合物(基于8-羟基喹啉的吡啶)的化学结构与抗菌活性之间的关系,以及取代基效应对其抗菌性能的影响。这些化合物是通过有效的方法合成的,它们的结构通过光谱方法(IR、1 H NMR、13 C NMR 和元素分析)确认。合成化合物的抗菌活性用阴沟肠杆菌(ATCC29893)、大肠杆菌(ATCC35218)、肺炎克雷伯菌(ATCC13883)、金黄色葡萄球菌( ATCC29213 )和不动杆菌(ATCC1606ATCC) 5株革兰氏阳性和革兰氏阴性菌进行检测。. 将四种合成化合物的抗菌活性结果与三种标准抗生素 [青霉素 G、红霉素和诺氟沙星(喹啉型)] 进行了比较。计算并讨论了活性化合物的最小抑制浓度 (MIC)。羟基喹啉衍生物的化学和生物活性与理论方法进行了比较。使用 HF/6-31++ g ( d, p) 基组。此外,羟基喹啉衍生物对癌蛋白的生物学活性分别为乳腺癌BRCT

5-unsymmetrically substituted1,4-dihydropyridines have been synthesized, which have ethoxycarbonyl and acetyl groups on 3- and 5-positions, respectively. A three-step procedure has been examined to increase the yield of the desired products, by suppressing the formation of the symmetrically substituted 3,5-diacetyl-1,4-dihydropyridines and 3,5-diethoxycarbonyl- 1,4-dihydropyridines.

The usage of potassium phthalimide (PPI) for the simple and green one-step multicomponent synthesis of Hantzsch 1,4-dihydropyridines, polyhydroquinolines, 3,4-dihydropyrimidin-2(1H)-ones/thiones, and octahydroquinazolinones under solventless conditions at 120 °C is reported. The method is operationally simple, environmentally benign, and has relatively high yields. The other merits of this method include efficient, clean, green, and catalyst reusability.
