A series of acetophenone derivatives (10a–10i, 11, 12a–12g, 13a–13g, 14a–14d and 15a–15l) were designed, synthesized and evaluated for antifungal activities in vitro and in vivo. The antifungal activities of 53 compounds were tested against several plant pathogens, and their structure–activity relationship was summarized. Compounds 10a–10f displayed better antifungal effects than two reference fungicides
一系列苯乙酮衍生物的(10A - 10 1,11,12A - 12克,13A - 13克,14A - 14D和15A - 15升)设计,合成并评价抗真菌活性在体外和体内。测试了53种化合物对几种植物病原体的抗真菌活性,并总结了它们的结构-活性关系。化合物10a – 10f的抗真菌作用比两种参考杀菌剂更好。有趣的是,最有效的化合物10d对Cytospora sp。,Botrytis cinerea,Magnaporthe grisea表现出抗真菌特性,IC 50值为6.0–22.6 µg / mL,尤其是Cytospora sp.。(IC 50 = 6.0 µg / mL)。在体内抗真菌试验中,第10天显示对灰葡萄孢具有55.3%的显着保护作用,对Cytospora sp则具有73.1%的显着保护作用。研究结果表明,10d可能是潜在的农药铅化合物,值得进一步研究。
