antinociceptive effects of three derivatives were 5.8, 5.4, and 5.1-folds of the effect of N(3)-phenacyluridine (1h) (16%), respectively. The structure-activity relationship of N(3)-substituted pyrimidine nucleosides was also discussed.
尿苷(1),胸苷(2),2'-脱氧尿苷(3),6-氮杂尿苷(4),2',3'-O-异丙基亚尿苷(5)和阿拉伯呋喃呋喃糖基尿嘧啶的七十八个N(3)取代衍生物(6)被合成并评估其抗伤害作用。N(3)-(2',4'-二甲氧基苯甲酰基)尿苷(1l),N(3)-(2',4'-二甲氧基苯甲酰基)2'-脱氧尿苷(3l)和N(3)-(2'通过热板测试,5'-二甲氧基苯甲酰基)呋喃糖基尿嘧啶阿拉伯糖(6m)分别具有93%,86%和82%的抗伤害感受作用。三种衍生物的抗伤害感受作用分别是N(3)-苯并吡啶(1h)(16%)的作用的5.8、5.4和5.1倍。N(3)取代的嘧啶核苷的结构活性关系也进行了讨论。
