present investigation is in the interest of some synthesized novel derivatives containing (5-(2-chloroquinolin-3-yl)-3-(aryl)-4,5-dihydro-1H-pyrazol-1-yl)(pyridin-4-yl)methanones (4a–o) moieties incorporated with different biological active heterocycles such as quinoline, pyrazoline and pyridinederivatives. For the determination of the compounds reported in this paper was based on IR, 1H NMR, 13C NMR
本研究符合某些含有(5-(2-氯喹啉-3-基)-3-(芳基)-4,5-二氢-1 H-吡唑-1-基)(吡啶-结合了不同的生物活性杂环(例如喹啉,吡唑啉和吡啶衍生物)的4-yl)methanenes(4a-o)部分。为了确定本文报道的化合物是基于IR,1 H NMR,13 C NMR和质谱数据,并筛选了相同的化合物对四种细菌(金黄色葡萄球菌,化脓性链球菌,大肠埃希氏菌,铜绿假单胞菌)和三种真菌(以氨苄青霉素和灰黄霉素为标准药物的白色念珠菌,黑曲霉,克拉维斯曲霉。使用MTT比色测定法(HeLa细胞系)进行细胞毒性研究。在筛选出的化合物中,4e,4f和4n表现出最强的抗菌活性,而化合物4d和4g表现出对真菌菌株最有活性。结果表明,化合物4o对所有微生物菌株均具有显着活性。从SAR研究的观点来看,观察到吸电子基团的存在显着增强了合成化合物的抗菌活性。另外,对HeLa细胞的MTT初步细胞毒性研究表明,有效的4e

4,5-Dihydroisoxazoles continue to attract considerable interest due to their wide spread biological activities. Here, we identify an efficient protocol for the preparation of 4,5-dihydroisoxazoles (2-isaxazolines) (4a-g) from quinolinyl chalcones. The nucleolytic activities of synthesized compounds were investigated by agarose gel electrophoresis. All these compounds were showed the remarkable DNA cleavage activity (concentration dependent) with pUC19 DNA at 365 nm UV light. The DNA cleavage activity was significantly enhanced by the presence of iminyl and carboxy radicals of DIQ. (C) 2012 Elsevier Ltd. All rights reserved.
