Eighteen novel benzamidine derivatives containing 1,2,3-triazole moieties were synthesized. The in vitro and in vivo fungicidal acitivities of the title compounds and the arylamidine intermediates against Colletotrichum lagenarium and Botrytis cinerea were tested. The synthesized benzamidines exhibited weak antifungal activities in vitro against the tested fungi, but some of the compounds showed excellent activities in vivo to the same strains. Among the compounds tested, 9b showed 79% efficacy in vivo against C. lagenarium at a concentration of 200 μg/mL, and the efficacy of compound 16d (90%) toward the same strain was even superior than that of the commercial fungicide carbendazim (85%).
合成了十八种含有1,2,3-三氮唑基团的新型苯脒类衍生物。测试了目标化合物和苯胺中间体对刺盘孢菌和葡萄孢菌的体外和体内杀菌活性。合成的苯脒在体外对测试的真菌显示出较弱的抗真菌活性,但其中一些化合物在体内对相同菌株显示出优异的活性。在测试的化合物中,9b在200 μg/mL浓度下对刺盘孢菌的体内效力为79%,化合物16d(90%)对相同菌株的效力甚至优于商业杀菌剂多菌灵(85%)。
