A series of pyrazolo[3,4-d]pyrimidine derivatives containing a Schiff base moiety were synthesized, characterised, and evaluated for their activity against tobacco mosaic virus (TMV). Biological assays indicated that several of the derivatives exhibited significant activity against TMV. In particularly, compounds 5y and 5aa displayed excellent inactivating activity against TMV, with half maximal effective
合成,表征并评估了一系列含有席夫碱部分的吡唑并[3,4- d ]嘧啶衍生物对烟草花叶病毒(TMV)的活性。生物学测定表明,几种衍生物显示出针对TMV的显着活性。特别是化合物5y和5aa表现出优异的针对TMV的灭活活性,最大有效浓度(EC 50)的一半分别为70.3和53.65μg/ mL,比利巴韦林(150.45μg/ mL)好得多,并且5aa优于宁南霉素(EC 50 = 55.35μg / mL)。化合物5y和5aa的相互作用TMV外壳蛋白(TMV-CP)用微尺度热泳和分子对接进行了研究。化合物5y和5aa表现出与TMV-CP的强结合能力,解离常数(K d)分别为22.6和9.8μM。这些发现表明,含有席夫碱的吡唑并[3,4- d ]嘧啶衍生物可能是潜在的抗病毒药。
