摘要:

将二甲氧基甲基引入到嘧啶环的4位, 设计并合成了15个结构新颖的磺酰脲类衍生物. 初步生物活性测试结果表明, 目标化合物具有较好的除草活性. 在75 g/ha的剂量下, 化合物6a和6g对油菜的芽前除草活性为100%, 与对照药单嘧磺隆和氯磺隆相当; 在50 mg/L的浓度下, 化合物6i和6o对3种病菌的离体抑制率都超过80%, 与对照药百菌清和多菌灵接近.

Abstract:

Sulfonylureas(SUs) as one of the most active herbicides targeted on acetolactate synthase(ALS). ALS was found not only in plants, but also in fungi and bacteria. In order to study the multi-biological activity of sulfonylurea(SU), a series of novel SU derivatives containing dimethoxymethyl pyrimidine moiety was designed, synthesized according to bioisosteric principles. The bioassay results indicated that the title compounds exhibited favorable herbicidal activity. Compounds 6a and 6g showed 100% pre-emergence inhibition activity against Brassica napus at the dosage of 75 g/ha, which were near to that of Monosulfuron and Chlorsulfuron(100%). In addtion, some of the title compounds also exhibited moderate antifungal activity. Compounds 6i and 6o showed over 80% antifungal activity against three fungi in vitro at the concentration of 50 mg/L, and closed to that of Chlorothalonil and Carbendazim. It provided useful information for designing new SU with highly herbicidal activity and fungicidal activity.

Key words: Sulfonylurea, Dimethoxymethyl, Acetolactate synthase, Herbicidal activity, Antifungal activity
