Semi-synthetic C-10 alkyl thio analogues of the cytotoxic natural alkaloid colchicine have been found to exhibit
cytotoxicity towards tumour cell lines at levels comparable to that of the natural product. An efficient synthesis of
10-alkyl thiocolchicines in mild conditions is proposed and the products are studied by 1H and 13C NMR, FT-IR, MS-EI
methods and elementary analysis. The crystal structure of 10-ethylthiocolchicine is characterised using X-ray diffraction
methods. Cytotoxic activity against selected cancer cell lines for all obtained 10-alkylthio analogues of colchicine is also
reported.
发现半合成的C-10烷硫基秋水仙碱类似物具有与天然秋水仙碱相当的细胞毒性,可对肿瘤细胞株产生毒性。提出了一种在温和条件下合成10-烷硫基秋水仙碱的高效方法,并通过1H和13C NMR、FT-IR、MS-EI方法以及元素分析对产物进行了研究。利用X射线衍射法表征了10-乙硫基秋水仙碱的晶体结构。此外,还报告了所有获得的10-烷硫基秋水仙碱类似物对选定癌细胞系的细胞毒活性。
