摘要: 对一系列溶剂分子的三维静电势及其统计上的导出参数进行了计算,运用多元线性回归分析建立了扑热息痛、利多卡因、氟派啶醇和磺胺嘧啶等四种常见药物在不同溶剂中溶解度与溶剂分子三维静电势参数之间的关系。从溶剂接受质子和给质子的能力以及极性大小方面对各药物的溶解性能进行了阐述。

关键词: 溶解度, 药物, 三维静电势, 定量结构-性质相关

Abstract: Ab initio optimizations at HF/6-31G* level and subsequent electrostatic potential calculationshave been performed for a group of 54 solvent molecules.Good correlation of solubilities of four usualdrugs, paracetamol, lidocaine, haloperidol and sulfadiazine in individual solvents with the computed quanti-ties derived from solvent molecule electrostatic potentials has been obtained.We find that Vmin, Vs,max, Ⅱ and σtot2 can be well used to predict the solubility behavior of the above drugs.
