Absorption spectra of eight 3-substituted-5,5-diphenylhydantoins have been recorded in fourteen solvents in the range 200–400 nm. The effect of solvent dipolarity/polarizability and solvent/solute hydrogen bonding interactions are analyzed by means of the linear solvation energy relationship (LSER) concept proposed by Kamlet and Taft. The lipophilic activity of the investigated hydantoins was estimated by the calculation of log 10 P values with the Advanced Chemistry Development Software. The calculated values of log 10 P were correlated with the ratio of the contributions of specific solvent interactions, and, by employing the linear dependence thus obtained, the pharmacological activity of the studied hydantoin derivatives is discussed.
已在 200-400 nm 范围内的 14 种溶剂中记录了 8 种 3-取代-5,5-二苯基乙内酰脲的吸收光谱。利用 Kamlet 和 Taft 提出的线性溶剂化能量关系 (LSER) 概念分析了溶剂偶极/极化性和溶剂/溶质氢键相互作用的影响。通过使用高级化学开发软件计算 log 10 P 值来估计所研究的乙内酰脲的亲脂活性。 log 10 P的计算值与特定溶剂相互作用的贡献比相关,并且通过利用由此获得的线性依赖性,讨论了所研究的乙内酰脲衍生物的药理活性。
