Thirteen new cantharidin derivatives including six cantharimide-amino acid adducts (1–6), five cantharimide dimers (7–11) and two cantharimide-aromatic compound hybrids (12–13) were isolated from Mylabris phalerata Pallas. Compounds 1–5 represent the first natural products combined through cantharimide and neutral amino acids. Compounds 7–11 are the first cantharimide dimers consisting of two different
十三包括6 cantharimide氨基酸加成物(新斑蝥素衍生物1 - 6,五个cantharimide二聚体()7 - 11)和两个cantharimide芳香族化合物杂种(12 - 13)从分离大斑芫菁帕拉斯。化合物1 - 5表示第一天然产物通过cantharimide和中性氨基酸组合。化合物7 – 11是第一个由两个不同的Cantharimide核心组成的Cantharimide二聚体。通过NMR光谱,单晶X射线衍射和半合成阐明了它们具有绝对构型的结构。化合物6显示出弱的细胞毒性对HepG2细胞,A549和MDA-MB-231细胞与IC 50倍的15.70±3.06的值,20.67±4.05 23.79和4.54± μ分别男,。
