The isolation and structure characterization of a dienone from the roots of Echinacea pallida, namely (8Z,11Z)-pentadeca-8,11-dien-2-one, are described here. To assess the configuration of this secondary metabolite, the stereoselective total synthesis of the two isomeric forms, (8Z,11Z)- and (8Z,11E)-pentadeca-8,11-dien-2-one, was undertaken and the structure elucidation of the natural compound was
本文描述了从紫锥菊的根,即(8Z,11Z)-pentadeca-8,11-dien-2-one的二烯酮的分离和结构表征。为了评估该次要代谢物的构型,进行了两种异构形式(8Z,11Z)-和(8Z,11E)-pentadeca-8,11-dien-2-one的立体选择性全合成,并阐明了结构明确地进行了天然化合物的制备。还在人T细胞白血病癌症系(Jurkat细胞)上评估了两种异构体的细胞毒性活性。结果表明,这些化合物对受试细胞系具有剂量依赖性的细胞毒性,并且具有中等水平的效力。
