Moreover, protective activities of compound 33 against bacterial leaf streak (BLS) and bacterial leaf blight (BLB) were 49.65% and 49.42%, respectively, which were superior to those of thiodiazole copper (44.28% and 41.51%) and bismerthiazol (38.89% and 40.09%). Protective activity of compound 33 against BLS was closely related to the improvement of defense-related enzyme activities, chlorophyll content
设计并合成了一系列新颖的6-磺酰基-1,2,4-三唑并[3,4- b ] [1,3,4]噻二唑衍生物。建立了CoMFA模型,以根据化合物的EC 50值分析定量的构效关系。该模型用于设计和合成具有较高活性的化合物32和33。化合物33对米黄单胞菌PV的EC 50值。米(Xoo)和黄单胞菌(Xanthomonas oryzae)。空心稗(XOC)分别为0.59和1.63 mg / L,分别高于硫代二唑铜(90.43和97.93 mg / L)和比美噻唑(68.37和75.59 mg / L)。此外,化合物33对细菌叶斑纹(BLS)和细菌叶枯病(BLB)的防护活性分别为49.65%和49.42%,优于硫代二唑铜(44.28%和41.51%)和比美噻唑(38.89%)。和40.09%)。化合物33对BLS的保护活性与防御相关酶活性,叶绿素含量和光合作用活化的提高密切相关。这与防御反应和光合作用相关蛋白的表达上调相一致。
