anti-tobacco mosaic virus (TMV) lead compound tetrahydro-β-carboline ester with the hydantoin, thiohydantoin, and urea motifs. These derivatives were synthesized from tetrahydro-β-carboline ester via a structural diversity-oriented synthesis in one step, and their biological activities were evaluated. Most of the derivatives exhibited anti-TMV activity higher than that of commercial plant virucide ribavirin
通过结合抗烟草花叶病毒(TMV)铅化合物四氢-β-咔啉酯与乙内酰脲,硫代乙内酰脲和脲基序,设计了一系列新型的β-咔啉衍生物。这些衍生物是由四氢-β-咔啉酯通过面向结构多样性的合成一步合成的,并对其生物学活性进行了评估。大部分的衍生物表现出抗TMV活性比商业植物杀病毒剂利巴韦林更高,例如化合物2,4,5,7,9,15,16,19,和21。与先导化合物相比,这些衍生物中的一些对小菜蛾和淡色库蚊具有良好的杀虫活性。同时,这些衍生物还表现出广谱杀真菌活性。系统的研究提供了强有力的证据,证明这些分子的乙内酰脲,硫代乙内酰脲和尿素基序可以改善和调节天然产物类似物的活性。
