Two cucurbitacins, dihydrocucurbitacin B (1) and cucurbitacin B (2), which can be obtained in large amounts from the roots of Wilbrandia ebracteata and from the fruits of Luffa operculata, respectively, were used as starting materials for the preparation of a library of 29 semi-synthetic derivatives. The structural changes that were performed include the removal, modification or permutation of functional
两种葫芦素(dihydrocucurbitacin B(1)和葫芦素B(2))可以分别作为原料从野勃氏菌(Wilbrandia ebracteata)的根和uff的丝瓜(Luffa operculata)的果实中大量获得,作为制备库的起始材料。 29种半合成衍生物。进行的结构变化包括环A和B以及侧链中官能团的去除,修饰或置换。所有新的半合成化合物以及1和2在体外测试了它们对非小细胞肺癌细胞(A549细胞)的细胞毒性作用。这些化合物中的一些显示出对A549肿瘤细胞有效的中等活性,尤其是在环A修饰的葫芦素B衍生物。
