However, the control of these diseases by conventional pesticides remains challenging due to development of resistances. We aimed to address this pending problem and developed a series of novel pyrimidine sulfonamide derivatives. Structurally, title compounds bear a unique oxyacetal group, which has a proven immune-activating effect. Compound E35 designed based on the 3D-QSAR model was demonstrated
细菌性叶枯病(BLB)和细菌性叶斑病(BLS)是由米黄单胞菌引起的两种严重的细菌性病害。oryzae ( Xoo ) 和Xanthomonas oryzae pv. oryzicola ( Xoc ),分别。然而,由于耐药性的发展,传统农药对这些疾病的控制仍然具有挑战性。我们旨在解决这个悬而未决的问题,并开发了一系列新型嘧啶磺酰胺衍生物。在结构上,标题化合物带有一个独特的氧缩醛基团,具有经证实的免疫激活作用。基于 3D-QSAR 模型设计的化合物E35在体外被证明是最佳的对Xoo和Xoc的活性,EC 50值分别为 26.7 和 30.8 mg/L,高于阳性对照双甲基噻唑(29.9 和 32.7 mg/L)和噻二唑铜(30.5 和 36.4 mg/L)。在预防水平上,生物活性试验表明,化合物E35对BLS的保护活性(43.7%)优于噻二唑铜(32.1%)。防御酶和蛋白质组学结果表明,化合物E
