Abstract
5′-Norcarbocyclic analogues of furano[2,3-d]pyrimidine nucleosides as well as 5-bromo and 5-iodouracil derivatives were synthesized to evaluate their potential antitumor activity. The halogenated derivatives display no cytotoxicity with respect to all tested cells: KB-3-1 (human epidermoid carcinoma), HeLa (human cervical epithelioid carcinoma), HuTu-80 (human duodenal cancer), B16 (mouse melanoma), and MDCK (normal epithelial). The cytotoxicity of the non-halogenated furano[2,3-d]pyrimidine derivatives increases with the lengthening of the alkyl chain of the substituent from 45 to 60 μm for octyl to from 3 to 10 μm for dodecyl.
摘要合成了呋喃[2,3-d]嘧啶核苷的5'-Norcarbocyclic类似物以及5-溴和5-碘尿嘧啶衍生物,以评估它们的潜在抗肿瘤活性。卤代衍生物对所有测试的细胞(KB-3-1(人表皮样癌)、HeLa(人宫颈上皮样癌)、HuTu-80(人十二指肠癌)、B16(小鼠黑色素瘤)和MDCK(正常上皮))均不显示细胞毒性。非卤代呋喃[2,3-d]嘧啶衍生物的细胞毒性随着取代基的烷基链长度从八烷基到十二烷基的延长而增加,从45到60 μm,从3到10 μm。
