A series of new 5-(1-hydroxy-2-haloethyl)-2'-deoxyuridines (3, 6, 8) were synthesized in 60-70% yields by addition of HOX (X = Br, Cl, I) to the vinyl substituent of the respective 5-vinyl-2'-deoxyuridines (2, 5, 7). Treatment of 3a,b with methanolic sulfuric acid afforded the corresponding 5-(1-methoxy-2-haloethyl)-2'-(deoxyuridines (4a,b). The 5-(1-hydroxy-2-chloroethyl) (3b), 5-(1-methoxy-2-bromoethyl) (4a), 5-(1-hydroxy-2-bromo-2-(ethoxycarbonyl)ethyl) (6a), and 5-(1-hydroxy-2-iodo-2-(ethoxycarbonyl)ethyl) (6b) derivatives exhibited in vitro antiviral activity (ID50 = 0.1-1 microgram/mL range) against herpes simplex virus type 1 (HSV-1). 5-(1-Hydroxy-2-bromo-2-(ethoxycarbonyl)-ethyl)-2'-deoxyuridine (6a) was the most active cytotoxic agent in the in vitro L1210 screen exhibiting an ED50 of 11 micrograms/mL relative to melphalan (ED50 = 0.15 micrograms/mL).
通过将HOX(X = Br、Cl、I)加成到相应的5-乙烯基-2'-脱氧尿苷(2、5、7)的乙烯基取代基上,以60 - 70%的产率合成了一系列新的5-(1-羟基-2-卤代乙基)-2'-脱氧尿苷(3、6、8)。用甲醇硫酸处理3a、b得到相应的5-(1-甲氧基-2-卤代乙基)-2'-(脱氧尿苷(4a、b)。5-(1-羟基-2-氯乙基)(3b)、5-(1-甲氧基-2-溴乙基)(4a)、5-(1-羟基-2-溴-2-(乙氧羰基)乙基)(6a)和5-(1-羟基-2-碘-2-(乙氧羰基)乙基)(6b)衍生物对1型单纯疱疹病毒(HSV-1)表现出体外抗病毒活性(ID50 = 0.1 - 1微克/毫升范围)。5-(1-羟基-2-溴-2-(乙氧羰基)乙基)-2'-脱氧尿苷(6a)是体外L1210筛选中最具活性的细胞毒剂,相对于美法仑(ED50 = 0.15微克/毫升),其ED50为11微克/毫升。
