5-(1-methoxy-2-azidoethyl)-2'-deoxyuridines (11). In vitro antiviral activities against HSV-1-TK(+) (KOS and E-377), HSV-1-TK(-), HSV-2, VZV, HCMV, and DHBV were determined. Of the newly synthesized compounds, 5-(1-cyanamido-2-iodoethyl)-2'-deoxyuridine (6) exhibited the most potent anti-HSV-1 activity, which was equipotent to acyclovir and superior to 5-ethyl-2'-deoxyuridine (EDU). In addition, it was significantly
通过将卤代氰胺(X-NHCN)区域特异性加成到5-乙烯基上,合成了一类新的5-(1-氰基氨基-2-卤代乙基)-2'-脱氧尿苷(4-6)和阿拉伯糖苷(7,8)。 5-乙烯基-2′-脱氧尿苷(2)和2′-阿拉伯尿苷(3)的取代基。2与叠氮化钠,硝酸铈铵,乙腈-甲醇或水反应,得到5-(1-羟基-2-叠氮基乙基)-(10)和5-(1-甲氧基-2-叠氮基乙基)-2'-脱氧尿苷(11)。确定了针对HSV-1-TK(+)(KOS和E-377),HSV-1-TK(-),HSV-2,VZV,HCMV和DHBV的体外抗病毒活性。在新合成的化合物中,5-(1-氰基氨基-2-碘乙基)-2'-脱氧尿苷(6)表现出最有效的抗HSV-1活性,与无环鸟苷等效,并且优于5-乙基-2' -脱氧尿苷(EDU)。此外,它对HSV-1的胸苷激酶缺陷株具有明显的抑制作用(EC(50)= 2.3-15.3 microM)。5-(1-氰
