5‐iodo‐(5), 5‐vinyl‐(6), and (E)‐5‐(2‐iodovinyl)‐2'‐deoxyuridines (7). We now report the synthesis of 5‐iodo‐3'O‐(1‐methyl‐1,4‐dihydropyridyl‐3‐carbonyl)‐5'‐O‐acetyl‐2'‐deoxyuridine (15) and 3'‐O‐(1‐methyl‐1,4‐dihydropyridyl‐3‐carbonyl)‐2'‐deoxyuridine (17). Quarternization of the 3'‐O‐(3‐pyridylcarbonyl) compounds (10,12) using iodomethane afforded the corresponding 1‐methyl pyridinium salts (13,14) which
描述了 3'-O-(1-甲基-1,4-二氢吡啶基-3-羰基)-偶联核苷的合成、抗病毒活性和分配系数 (P)。这些新化合物的设计旨在提高亲脂性,从而在不影响亲本核苷的抗 HSV-1 活性的情况下向 CNS 递送。我们之前已经报道了 5-iodo- (5)、5-vinyl- (6) 和 (E) 的 3'-O- (1-methyl-1,4-dihydropyridyl-3-carbonyl) 类似物的合成 - 5-(2-碘乙烯基)-2'-脱氧尿苷 (7)。我们现在报告合成 5-iodo-3'O- (1-methyl-1,4-dihydropyridyl-3-carbonyl) -5'-O-acetyl-2'-deoxyuridine (15) 和 3'-O- (1-甲基-1,4-二氢吡啶基-3-羰基)-2'-脱氧尿苷(17)。3'-O-(3-吡啶基羰基)化合物的季铵化 (10, 12) 使用碘甲烷得到相应的
