1-b]thiophene-1-carbonitrile (1). Structure characterization of the thioxo derivative 7 was also performed and its reaction with some chloro and bromoalkyl reagents was studied. Moreover, the prepared products were tested for antiviral activity against H5N1 virus [A/chicken/Egypt/1/2006 (H5N1)] by determination of both EC50 and LD50 and confirmed by plaque reduction assay on MDCK cells. Compounds 5, 7 and 8 showed
从2-氨基-4,5-二氢萘并[2,1- b ]噻吩-1开始,制备了几种含有二氢萘,萘[ 2,1- b ]噻吩和噻吩并[2,3- d ]嘧啶环系统的衍生物。腈(1)。还进行了thioxo衍生物7的结构表征,并研究了其与某些氯和溴代烷基试剂的反应。此外,通过确定EC 50和LD 50来测试制备的产物对H5N1病毒的抗病毒活性[A /鸡/埃及/ 1/2006(H5N1)],并通过在MDCK细胞上的噬斑减少试验来证实。化合物5,7和8 与其他测试化合物相比,显示出最高的效果。
