drugs 2',3'-dideoxycytidine (ddC, 1) and 3'-fluoro-ddC (2), involving N4-substitution with (N,N-dialkylamino)methylene side chains, is described. The increase in the partition coefficients for the prodrug series, compared to those of the parent drugs 1 and 2, ranged from 1.5- to 122-fold and from 1.6- to 175-fold, respectively. At pH 7.4, 37 degrees C, the hydrolytic t1/2 values ranged from 2 to 52
抗HIV药物2',3'-二脱氧胞苷(ddC,1)和3'-fluoro-ddC(2)的一系列新型亲脂性前药衍生物的合成,涉及用(N,N-二烷基氨基)进行N4-取代描述了亚甲基侧链。与母体药物1和2相比,前药系列分配系数的增加分别为1.5到122倍和1.6到175倍。在pH 7.4(37摄氏度)下,水解t1 / 2值介于2至52小时之间,二异丙基衍生物(3d和4d)在系列中最稳定。3d和4d在水中的溶解度分别比1和2高4倍和1.7倍。评估了3d,4a和4d的体外抗逆转录病毒活性;结果表明在测定条件下有效的前药转化为药物。
