We here report the synthesis of a series of 12 hybrid molecules composed of a colchicine moiety and a pironetin analogue fragment. The two fragments are connected through an ester–amide spacer of variable length. The cytotoxic activities of these compounds and their interactions with tubulin have been investigated. Relations between the structure and activity are discussed. Since the spacer is not
我们在这里报告了一系列由秋水仙碱部分和吡咯丁酮类似物片段组成的12个杂种分子的合成。这两个片段通过长度可变的酯-酰胺间隔基连接。已经研究了这些化合物的细胞毒性活性及其与微管蛋白的相互作用。讨论了结构和活动之间的关系。由于间隔物的长度不足以允许杂合分子同时结合至微管蛋白上的秋水仙碱和吡咯丁酮位点,因此研究的另一个特征是这些分子是通过吡咯丁酮末端(不可逆共价结合)还是通过吡咯丁酮与后者相互作用。秋水仙碱末端(可逆的非共价结合)。
