Deacetylcolchicine was reacted with substituted benzyl halides to provide a library of compounds for biological analysis. Compound 7 (3,4-difluorobenzyl-N-aminocolchicine) was shown to possess cytotoxicity in cancer cell lines in the low nanomolar range. Significantly, it showed no loss of activity in the resistant A2780AD ovarian carcinoma cell line known to overexpress the ABCB1 drug transporter
使去乙酰基秋水仙碱与取代的苄基卤反应,以提供用于生物学分析的化合物库。化合物7(3,4-二氟苄基-N-氨基秋水仙碱)在癌细胞系中具有低纳摩尔范围的细胞毒性。值得注意的是,它在已知过表达ABCB1药物转运蛋白的耐药A2780AD卵巢癌细胞系中未显示出活性损失,也不受HeLa转染细胞中III类β-微管蛋白过表达的影响。
