在这项工作中,有效地合成了一系列内酯1,4-二氢喹啉衍生物4并通过1 H和13 C NMR进行了表征。评价了所合成的化合物对细菌菌株牙龈卟啉单胞菌,黑线菌,血链球菌和血链球菌以及对结核分枝杆菌,鸟分枝杆菌和堪萨斯分枝杆菌的体外抗菌活性。结果表明,所评价的化合物对革兰氏阴性细菌更具活性。化合物4ba,4bb,4BG,4bi,40亿,4CH,和4 Cl显示温和的抗菌活性对牙龈卟啉菌。4bi是对三种分枝杆菌最具活性的化合物。根据结构-活性关系研究,我们观察到苄基环上存在硝基,二氢喹啉环上存在亚甲基二氧基,可以增强衍生物的抗菌活性。

of this study was the synthesis and lead structure selection of a best anti-leukemic agent from a library of aza-podophyllotoxin analogues (APTs). To this end, we report a scalable, modified multicomponent reaction using a "sacrificial" aniline partner as a more general route to rapidly construct the pivotal library of 50 APT analogues. Our preliminary structure activity relationship studies for anti-leukemic

A series of 4-aza-podophyllotoxin derivatives have been synthesized regioselectively via the three-component reaction of aldehydes, aromatic amines, and tetronic acid catalyzed by L-proline. This method has the advantages of high yield, high regioselectivity, extensive adaptability, easy operation, and environmental friendliness. These compounds were also investigated in vitro, and sonic were found to have good anticancer activity.

and 4ci displayed moderate antibacterialactivity against P. gingivalis. 4bi was the most active compound against the three strains of Mycobacterium. Based on structure–activity relationship studies, we observed that the presence of a nitro group on the benzylic ring and a methylenedioxy group on the dihydroquinoline ring enhanced the antibacterialactivity of the derivatives.
