3'-C-Methyladenosine (3'-Me-Ado) is a mechanism-based ribonucleotide reductase inhibitor endowed with antitumor activity against both human leukemia and carcinoma cell lines. In this paper, we report the synthesis and antitumor evaluation of a series of purine and pyrimidine 3'-C-methylribonucleoside analogs of 3'-Me-Ado. A stereoselective synthesis of the arabino analog of 3'-Me-Ado is also described. Among the tested compounds, only 3'-C-methyluridine showed moderate antitumor activity against human myelogenous leukemia K562 cell line.
3'-C-甲基腺苷(3'-Me-Ado)是一种以机制为基础的核糖核苷酸还原酶抑制剂,具有抗肿瘤活性,可对人类白血病和癌细胞系产生作用。本文报告了一系列嘌呤和嘧啶3'-C-甲基核糖核苷类似物的合成和抗肿瘤评价,还描述了3'-Me-Ado的阿拉伯糖类似物的立体选择性合成。在测试的化合物中,只有3'-C-甲基尿苷对人类骨髓性白血病K562细胞系显示出中等的抗肿瘤活性。
