primary alkyl- or arylamines gave the corresponding N6,5′-bis-ureido- or 5′-carbamoyl-N6-ureidoadenosine derivatives in good yields (33–72% and 39–83%; 10a–e and 15a–e, respectively). Significant antiproliferative activities (IC50 ≈ 4–10 μg/mL) were observed for a majority of the N6,5′-bis-ureido derivatives, whereas the 5′-carbamoyl-N6-ureido derivatives were generally less active (IC50 >100 μg/mL).

我们已经开发了制备有效的方法Ñ 6,5'-双- ureidoadenosine衍生物和它们的5'-氨基甲酰基- ñ 6 -脲基同源。的治疗5'-叠氮基-5'-脱氧Ñ 6 - (ñ -烷基或-arylurea)腺苷衍生物(6A - d)用H 2 /钯-碳或PH 3次/时2 O,随后Ñ -甲基p -nitrophenylcarbamate给ñ 6,5'-双-脲基产品7A - d在49-78%的产率。5'-氨基甲酰基-N 6中的类似衍生物-ureido系列的制备方法是,先用N-甲基-对-硝基苯基氨基甲酸酯处理2',3'- bis- O -TBS-腺苷(11),然后用适当的异氰酸酯酰化,得到13a - d,产率为45-69%。通过用氯甲酸乙酯处理5' - N-甲基脲基或5'- N-甲基氨基甲酰腺苷衍生物,在55中得到N 6-乙氧羰基衍生物(9和14),从而获得了一种更通用的途径来从这两个系列中获取
