an important pharmacophore, two series of 2-(aryloxymethyl) benzoxazole and benzothiazole derivatives were synthesized and their antifungal effects against eight phytopathogenic fungi were evaluated. Compounds 5a, 5b, 5h, and 5i exhibited significant antifungal activities against most of the pathogens tested. Especially 5a, 5b, 5h, 5i, 5j, and 6h inhibited the growth of F. solani with IC50 of 4.34⁻17
以苯并恶唑和苯并噻唑支架为重要药效基团,合成了两个系列的2-(芳氧基甲基)苯并恶唑和苯并噻唑衍生物,并评价了它们对八种植物病原真菌的抗真菌作用。化合物5a,5b,5h和5i对大多数测试的病原体均表现出显着的抗真菌活性。尤其是5a,5b,5h,5i,5j和6h抑制了茄形假丝酵母的生长,IC50为4.34±17.61μg/ mL,强于阳性对照羟氨唑(IC50为38.92μg/ mL)。5h是最有效的针对F. Solani的抑制剂(IC50为4.34μg/ mL),其效力是羟甲唑的约9倍。大多数测试化合物对灰葡萄孢均表现出显着的抗真菌作用(IC50为19.92⁻77.41μg/ mL),其中5a是最好的一种(IC50为19.92μg/ mL)。比较了结构-活性关系(SAR)。结果表明,电子吸引能力和取代基的位置对生物活性具有重要影响。此外,对酿酒酵母的脂质转移蛋白sec14p进行了对接研究,初步
