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
