4-dihydropyridyl-3-carbonyl)-2′-deoxyuridine (15a), 5-vinyl-3′-O-(1-methyl-1,4-di-hydropyridyl-3-carbonyl)-2′-deoxyuridine (15b) and (E)-5-(2-iodovinyl)-3′-O-(1-methyl-1,4-dihydropyridyl-3-carbonyl)-2′-deoxyuridine (15c) were synthesized for future evaluation as lipophilic brain-selective antiviral agents for the treatment of herpes simplex encephalitis. Quaternization of the 3′-O-(3-pyridylcarbonyl) compounds
5-碘-3'- O-(1-甲基-1,4-二氢吡啶基-3-羰基)-2'-脱氧尿苷(15a),5-乙烯基-3'- O-(1-甲基-1,4 -二氢吡啶基-3-羰基)-2'-脱氧尿苷(15b)和(E)-5-(2-碘乙烯基)-3'- O-(1-甲基-1,4-二氢吡啶基-3-羰基)合成了-2'-脱氧尿苷(15c)作为用于治疗单纯疱疹性脑炎的亲脂性脑选择性抗病毒药,以供将来评估。使用碘甲烷对3'- O-(3-吡啶基羰基)化合物10-11进行季铵化,得到相应的1-甲基吡啶鎓盐12-13用连二亚硫酸钠还原,得到相应的3' - O-(1-甲基-1,4-二氢吡啶基-3-羰基)化合物14-15。
