A series of new colchicine analogues (6a-f, 8a-b) were synthesized by coupling nitrates with C-7 and replacement of the 10-methoxy with N(CH3)2 in order to determine their cytotoxic activity. The compounds were synthesized in good yield and the structures of all newly synthesized compounds were established on the basis of their IR, 1H NMR and elemental analysis. The synthesized compounds were tested in vitro antitumor activity against four human cancer cell lines by MTT assay. It was found that many of the derivatives displayed significant activity, particularly, compound 6c showed more potent cytotoxic activities than colchicine.
为了确定其细胞毒性活性,研究人员通过将硝酸盐与 C-7 偶联,并用 N(CH3)2 替换 10-甲氧基,合成了一系列新的秋水仙碱类似物(6a-f、8a-b)。根据红外光谱、1H NMR 和元素分析,确定了所有新合成化合物的结构。利用 MTT 法对合成的化合物进行了体外抗肿瘤活性测试,以检测它们对四种人类癌细胞系的抗肿瘤活性。结果发现,许多衍生物都显示出了显著的活性,尤其是化合物 6c 比秋水仙碱显示出了更强的细胞毒性活性。
