Forty one novel 1,3,4‐oxadiazole/thiadiazole thioether derivatives containing phenoxy moiety were designed and synthesized. Bioassay demonstrated that some of them showed remarkable activities against Tylenchulus semipenetrans in vitro and in vivo. Compounds 20, 21, 35 and 39 showed excellent lethal activities after treatment for 48 h in vitro, with LC50 values of 13.4 ± 1.8, 11.7 ± 2.5, 13.7 ± 2.4
设计并合成了41种新颖的含苯氧基的1,3,4-恶二唑/噻二唑硫醚衍生物。生物测定表明,他们中的一些表现出显着的抵抗活动半穿刺 在体外和体内。化合物20,21,35和39表现出优异的致死活性治疗48小时后在体外,用LC 50倍·L 13.4±1.8的值,11.7±2.5,13.7±2.4和13.3±1.1毫克-1,分别,将其明显优于邻苯二甲酸酯(49.1±2.8 mg·L –1)和阿维菌素(26.6±2.3 mg·L –1)。化合物21可以在200 mg·L –1的体内有效地控制由T. semipenetrans引起的柑橘线虫病,其抑制作用为(68±3)%,甚至优于阿维菌素((63±2)%)。建立了三维定量结构-活性关系(3D-QSAR)的CoMFA和CoMSIA模型。化合物33是根据3D-QSAR模型设计的,在体外(LC 50 = 9.8±1.4 mg·L –1)和体内((70±5)%)
