On the basis of the scaffolds widely used in drug design, a series of novel spirooxindole derivatives containing hydantoin, thiohydantoin, urea, and thiourea moieties have been designed, synthesized, characterized, and first evaluated for their biological activities. The diastereoselectivity mechanism is proposed, and the systematic conformational analysis is performed. The bioassay results show that
在药物设计中广泛使用的支架的基础上,已设计,合成,表征并首次评估了一系列含有乙内酰脲,巯乙内酰脲,尿素和硫脲部分的新型螺并吲哚衍生物。提出了非对映选择性机理,并进行了系统的构象分析。生物测定结果表明,目标化合物对烟草花叶病毒(TMV)具有中等至良好的抗病毒活性,其中化合物22在体外具有最高的抗病毒活性以及体内的灭活,治疗和保护活性(分别为45±1,47±3、50±1和51±1%,500 mg / L),高于利巴韦林(38±1,36±1,38±1,和36±1%,500毫克/升)。因此,化合物22是抗TMV发展的有希望的候选物。大多数这些化合物显示出抗14种植物致病真菌和抗选择性杀菌活性的广谱杀真菌活性轮纹轮纹病菌,核盘菌,和纹枯病菌。此外,这些化合物中的一些还表现出对淡色库蚊,Mythimna separata,Helicoverpa armigera和Pyrausta nubilalis的
