novel chitin synthesis inhibitors (CSIs) with good activity, benzoylphenylurea, a typical kind of CSIs, was chosen as the lead compound and 15 novel derivatives containing furan moieties were designed by converting the urea linkage of benzoylphenylureas into a semicarbazide and changing the aniline part into furoyl groups. The title compounds were synthesized by the reaction of substituted benzoyl isocyanates
为了寻找具有良好活性的新型几丁质合成抑制剂(CSIs),选择典型的CSIs类苯甲酰苯脲作为先导化合物,通过将苯甲酰苯脲的脲键转化为氨基脲基团并改变其结构,设计了15种含有呋喃部分的新型衍生物。苯胺部分变成糠酰基。标题化合物由取代苯甲酰异氰酸酯与5-(取代苯基)-2-呋喃酰肼反应合成,结构经IR、1H-NMR、元素分析和单晶X射线衍射分析(化合物E2 )。生物测定结果表明,标题化合物表现出良好的杀虫活性,尤其是对小菜蛾(Plutella xylostella L.),但杀真菌活性较低。令人鼓舞的是,标题化合物对人早幼粒细胞白血病细胞系(HL-60)具有明显的抗癌活性,部分标题化合物对人肝癌细胞系(Bel-7402)、人胃癌细胞系(BGC-823)也有活性, 和人鼻咽癌细胞系 (KB)。结果表明,先导化合物中的连接对生物活性和光谱很重要。尿素键的修饰是发现新农药和候选药物的有效策略。结果表明,
