Alkaloids of Importance in Plant-Insect Interactions

本研究的重点是研究黄松和科罗拉多蓝云杉中2,6-二取代胡椒碱生物碱的生物合成。此外，生物碱的生物活性测试应该确定这些化合物在植物/草食相互作用中的重要性。植物/昆虫相互作用的研究主要集中在对从剑齿苋科植物和幼虫以剑齿苋为食的特殊鳞翅目植物中提取的环烯醚萜苷的研究上。预计自由飞行的蝴蝶可以用来帮助识别幼虫食物植物。有了这个更新奖，合成有机项目支持了科罗拉多州立大学化学系Frank R. Stermitz博士的研究。Stermitz教授将专注于针叶树中胡椒碱生物碱的分离、结构、生物合成和生态作用，以及环烯醚萜苷的分离和结构表征以及这些化合物在植物/昆虫相互作用中的重要性。* * *

9321977 Stermitz The focus of this research will be the study of the biosynthesis of 2,6-disubstituted piperidine alkaloids in Ponderosa pine and Colorado blue spruce. Further, the bioactivity testing of the alkaloids should define the importance of these compounds in plant/herbivore interactions. Research on plant/insect interactions center on the study of iridoid glycosides from Scrophulariaceae and the specialist lepodoptera whose larva feed on the plants. It is anticipated that free-flying butterflies can be used to help identify larval food plants. %%% With this renewal award, the Synthetic Organic Program is supporting the research of Dr. Frank R. Stermitz of the Department of Chemistry at Colorado State University. Professor Stermitz will focus his work on the isolation, stucture, biosynthesis and ecological role piperidine alkaloids in conifer species and in the isolation and structural characterization of iridoid glycosides and the importance of these compounds in plant/insect interactions. ***
