(9-mono-6-MP) prodrugs have been synthesized and characterized. The ability of the 6-mono-6-MP prodrugs to deliver 6-mercaptopurine (6-MP) through hairless mouse skin from isopropyl myristate (IPM) and propylene glycol (PG) has been evaluated. There was a good correlation between the log experimental permeability coefficients from the diffusion data and calculated solubility parameters of the prodrugs. Although
合成并表征了同源系列的S6-酰氧基甲基-6-巯基嘌呤(6-mono-6-MP)和两个9-酰氧基甲基-6-巯基嘌呤(9-mono-6-MP)前药。评估了6-mono-6-MP前药从肉豆蔻酸异丙酯(IPM)和丙二醇(PG)通过无毛小鼠皮肤递送6-巯基嘌呤(6-MP)的能力。从扩散数据得出的对数实验渗透系数与计算出的前药溶解度参数之间具有良好的相关性。尽管乙酰基通过IPM的戊基6-单-6-MP前体药物输送6-MP的速率之间没有统计学差异,但是丁酰基和戊基的前体药物从PG输送6-MP的效果明显更好。对于给定的溶解度参数值,6-mono-6-MP前药在水中和IPM中的溶解度较低,并且比以前研究的S6,9-双酰氧基甲基-6-MP(6,9-bis-6-MP)前药更易溶于PG。另一方面,对于给定的溶解度参数,6,9-bis-6-MP前药通常更有效地从IPM和PG输送6-MP。所评估的单一9-mono-6-MP前药比6-mono-或6
