摘要：

通过活性基团拼接的方法, 将氨基甲酸酯结构和1H-1,2,4-三唑-5-胺有机结合, 设计合成了一系列结构新颖的多取代1H-1,2,4-三唑-5-氨基甲酸酯类化合物(5和6), 所有化合物的结构经核磁共振(NMR), 红外光谱(IR), 高分辨质谱(HRMS)及元素分析等方法确证.初步杀虫活性测定结果表明, 大部分化合物对桃蚜[Myzus persicae(Sulzer)]具有良好的杀虫活性, 致死率大于90%. 精密毒力测试结果表明, 化合物5b的半致死浓度(LC₅₀)为9.49 μg/mL, 具有进一步研究开发的价值.抑菌活性初步测试结果表明该类化合物的抑菌活性一般, 在50 μg/mL浓度下少数化合物也表现出一定的离体抑菌活性. 对此类化合物的构效关系进行了讨论.

Abstract:

A series of novel (1H-1,2,4-triazol-5-yl)carbamates(5 and 6) was synthesized via the method of combining the crucial sub-structures of carbamates and 1H-1,2,4-triazole-5-amines in one molecules. Their structures were characterized by nuclear magnetic resonance(NMR), infrared(IR) spectrometry, high resolution mass spectrometry(HRMS) and elemental analysis. The preliminary insecticidal activity assays indicated that the lethal rates of target compounds to Myzus persicae were good at the concentration of 500 μg/mL. And the lethal rate of several compounds was more than 90%. Further research of these compounds against Myzus persicae indicated that compound 5b showed considerably high activity with a LC₅₀ of 9.49 μg/mL, which confirmed that these compounds are valuable for further study. The preliminary fungicidal activity assays indicated that these compounds exhibited low fungicidal activity against tested fugi in vitro. At a dose of 50 μg/mL, only a few of compounds gave limited inhibition on mycelium growth. In addition, the structure-activity relationship was also discussed.
