mechanism. Topical delivery of selected derivatives of acetaminophen (APAP), Th and 6MP was examined in in vitro diffusion cell experiments from IPM across hairless mice skins. The prodrug of APAP and 6MP increased permeation across the skin by about 2- and 4-fold, respectively, compared to the parent drug. NANAOCAM promoieties can act as novel prodrug derivatives of phenol, imide and thiol containing drugs
在水性缓冲液中进行了取代酚、茶碱 (Th) 和 6-巯基嘌呤 (6MP) 的新型 N-烷基-N-烷氧基羰基氨基甲基 (NANAOCAM) 衍生物的合成、表征和水解。通过苯酚的N-芳基-N-烷氧基羰基氨基甲基(NArNAOCAM)衍生物的合成、表征和水解,进一步研究了水解机理。水解遵循假单分子一级动力学,并通过 S(N)1 型机制进行。在来自 IPM 的无毛小鼠皮肤的体外扩散细胞实验中,对选定的对乙酰氨基酚 (APAP)、Th 和 6MP 衍生物的局部递送进行了检查。与母体药物相比,APAP 和 6MP 的前药分别使皮肤渗透增加了约 2 倍和 4 倍。
