摘要: 将有机化合物中常见原子按元素周期表的族和杂化状态进行分类, 基于药物与受体相互作用的3类非键效应, 从分子空间立体结构出发得到了一种新型三维原子场全息作用矢量(3D-HoVAIF). 利用该矢量对几类典型药物体系进行了系统的QSAR研究, 结果表明, 3D-HoVAIF能够有效地提取药物分子的立体结构信息并与其生物活性呈良好线性关联.

Abstract: In order to classify the atoms in organic compounds in terms of their families in periodic table of elements and hybridization status, a novel three dimensional holographic vector of atomic interaction field (3D-HoVAIF) is derived from molecular steric structures based on drug-receptor nonbonding interactions. Applying 3D-HoVAIF to QSAR studies on a series of classical drug systems, it is confirmed that 3D-HoVAIF is able to efficiently extract molecular sterical potential information, thus well related with the bioactivities.

Key words: Three dimensional holographic vector of atomic interaction field, Molecular structural charac-terization, Quantitative structure-activity relationship, Partial least square regression
