Currently, there is insufficient viricide to effectively control tomato spotted wilt virus (TSWV). To address this pending issue, a series of thienopyrimidine-containing dithioacetal derivatives were prepared and tested for their anti-TSWV activities. A subsequent three-dimensional quantitative structure–activity relationship was constructed to indicate the development of optimal compound 35. The obtained
目前,没有足够的杀病毒剂来有效控制番茄斑枯病病毒(TSWV)。为了解决这个悬而未决的问题,制备了一系列含噻吩并嘧啶的二硫缩醛衍生物,并测试了它们的抗 TSWV 活性。随后构建了一个三维定量构效关系,以指示最佳化合物35的开发。得到的化合物35具有优异的抗TSWV治疗、保护和灭活活性(分别为63.0、56.6和74.1%),化合物35的保护和灭活活性的EC 50值分别为 252.8 和 113.5 mg/L,优于宁南霉素(284.8 和 144.7 mg/L)和香草六索冰米(624.9 和 300.0 mg/L)。此外,化合物35的抗 TSWV 活性与防御相关酶活性、增强光合作用和降低应激反应有关,从而增强抗病性。
