chlorosis virus (ToCV) has caused great harm to the production of tomato worldwide. To develop efficient anti-ToCV agents, some novel 4(3H)-quinazolinone derivatives containing dithioacetal were designed and synthesized, and their anti-ToCV activities were evaluated by microscale thermophoresis (MST) using ToCV coat protein (ToCV-CP) as a new target. The results showed that some compounds had a strong
番茄绿化病(ToCV)对全世界的番茄生产造成了极大的伤害。为了开发有效的抗ToCV药物,设计并合成了一些新型的含二硫缩醛的4(3H)-喹唑啉酮衍生物,并使用ToCV外壳蛋白(ToCV-CP)作为新的微尺度热电泳(MST)评估了它们的抗ToCV活性。目标。结果表明,某些化合物与ToCV-CP具有很强的结合能力。特别地,化合物C5和C22对ToCV-CP具有优异的结合能力,结合常数分别为0.24和0.25μM。此外,当番茄分别用化合物C5和C22处理时,ToCV-CP基因表达水平可降低81.05%和87.59%,这明显高于宁南霉素(NNM)处理后的水平(43。88%)和铅化合物香草柳索冰蜜(XCLSBM)治疗(63.56%)。因此,这项工作表明,包含二硫缩醛部分的4(3H)-喹唑啉酮衍生物可用作新型抗ToCV药物。
