摘要: 应用量子化学参数研究羧酸类化合物的结构与其萃取性能的相关性,并将二维结构参数应用到三维构效关系研究中,从而有效地改善了CoMFA法的结果,用pKa值来表征羧酸类化合物的萃取性能.

Abstract: The quantum chemical descriptors were used for QSPRstudy of the structures of carboxylic acids and their pKa values. The algorithm of "Leaps and Bounds" regression was performed for selection of the variables. The CoMFAmethod was carried out for 3D-QSPR. As the introduction of the charge of oxygen atom (Q2), the results obtained by CoMFAwere improved greatly.

Key words: Quantum chemical descriptors, CoMFA method, Carboxylic acid compounds, pKa value, Chemometrics
