The (chloroethyl)nitrosourea analogues of 2'-deoxyuridine and 2'-deoxy-5-fluorouridine, 3'-[3-(2-chloroethyl)-3-nitrosoureido]-2',3'-dideoxyuridine (3'-CdUNU, 7) and 3'-[3-(2-chloroethyl)-3-nitrosoureido]-2,3'-dideoxy-5-fluorouridine (3'-CFdUNU, 8), have been synthesized by treatment of the corresponding 3'-amino nucleosides with chloroethyl isocyanate, followed by nitrosation of the resulting ureas
2'-脱氧尿苷和2'-脱氧-5-氟尿苷,3'-[3-(2-氯乙基)-3-亚硝基脲基] -2',3'-二脱氧尿苷(3'-CdUNU)的(氯乙基)亚硝基脲类似物,7)和3'-[3-(2-氯乙基)-3-亚硝基脲基] -2,3'-二脱氧-5-氟尿苷(3'-CFdUNU,8),通过处理相应的3' -氨基核苷与氯乙基异氰酸酯,然后亚硝化所得的脲。核苷亚硝基脲7和8在荷瘤小鼠中对L1210白血病表现出显着的抗癌活性。在40 mg / kg的最佳剂量水平下,7和8分别产生90%和60%的“治愈”(大于60天存活者)。讨论了构效关系。
