effects are major priority for researchers. Two series of N-substituted indole derivatives i.e. N-substituted indole based chalcones (12a-g) and N-substituted indole based hydrazide-hydrazones (18a-g, 19a-f, 21 a-g) were synthesized. The synthesized compounds were characterized by 1H NMR, 13C NMR, Mass and FT-IR spectral data. Further these derivatives were evaluated for their antimicrobial potential against
利什曼病和微生物感染是导致全球死亡率和发病率的两个主要因素。因此,开发具有减少的副作用的新颖,有效和安全的抗真菌药和抗微生物剂是研究人员的首要任务。合成了两个系列的N-取代的吲哚衍生物,即N-取代的基于吲哚的查耳酮(12a-g)和N-取代的基于吲哚的酰肼-azo(18a-g,19a-f,21ag)。合成的化合物通过1 H NMR,13 C NMR,质量和FT-IR光谱数据表征。进一步评估了这些衍生物的抗大肠杆菌,枯草芽孢杆菌,恶臭假单胞菌和粘链假丝酵母的抗微生物潜力,以及抗利什曼原虫的前鞭毛体的抗疟药潜力。化合物18b,18d和19d表现出显着的活性,对枯草芽孢杆菌的IC50为0.19±0.03 µM,0.14±0.02 µM和0.16±0.06 µM,与氯霉素相当(IC50为0.25±0.03 µM)。化合物12b和12c在抗盲肠测定中表现出24.2±3.5 µM和21.5±2.1 µM
10-Camphorsulfonic acid ((±)-CSA) catalyzed facile one-pot synthesis of a new class of 2,5-disubstituted 1,3,4-oxadiazoles
A convenient and efficient one-potsynthesis of 2,5-disubstituted-1,3,4-oxadizoles is described. Various carboxylic acid hydrazides reacted efficiently with different carboxylic acid chlorides and 10-camphorsulfonic acid. This methodology was successfully applied to the synthesis of a series of 2H-chromene substituted 1,3,4-oxadiazole derivatives in good to high yields.
antiproliferative activity against the cells of human cancer lines for 2-(2,4-dihydroxyphenyl)-5-(4-methoxybenzyloxy)-1,3,4-thiadiazole was found with ID(50) values comparable (HCV29T and SW707) or significantly lower (T47D) than for cisplatin applied as the reference compound. The influence of 5-substiution type of 2-(2,4-dihydroxyphenyl)-1,3,4-thiadiazoles on antiproliferative activity is discussed.
