Two different types of soft alkyl ether prodrugs incorporating ethyleneoxy groups into the promoiety have been synthesized for a model phenol (acetaminophen, APAP): alkyloxycarbonyloxymethyl type (AOCOM) and N-alkyl-N-alkyloxycarbonyl-aminomethyl type (NANAOCAM). The solubilities in isopropyl myristate, S(IPM), and water, S(AQ), partition coefficients between IPM and pH 4.0 buffer, K(IPM:4.0), and
已经为模型苯酚(对乙酰氨基酚,APAP)合成了两种不同类型的软烷基醚前药,这些前药将亚乙基氧基基团并入前体部分:烷氧基羰基氧基甲基型(AOCOM)和 N-烷基-N-烷氧基羰基-氨基甲基型(NANAOCAM)。肉豆蔻酸异丙酯 S(IPM) 和水 S(AQ) 中的溶解度、IPM 和 pH 4.0 缓冲液之间的分配系数 K(IPM:4.0),以及通过无毛小鼠皮肤从 IPM 递送含有 APAP 的总物种, J(MMIPM),已经测量了前药。J(MMIPM) 值由 Roberts-Sloan (RS) 方程准确预测。每种类型仅实现了 JMMIPM 的适度增长(约 1.4 倍)。唯一比APAP更水溶性和更脂溶性的前药没有改善APAP的J(MMIPM)。
