摘要: 用量子化学密度泛函方法B3LYP对9种头孢类抗生素的电子结构进行了理论计算, 并对它们进行了定量构效关系研究. 建立了头孢类抗生素分子的结构-活性数学模型: 头孢类抗生素的抑菌活性与QC8, QC7以及偶极距(Dipole)呈正相关关系.

关键词: 头孢类抗生素, 量子化学, 密度泛函方法, 定量构效关系

Abstract: The molecular structures of nine kinds of cephalosporin derivatives were optimized by using density functional theory(DFT)B3LYP method of quantum chemistry, and the quantitative structure-activity relationship of these cephalosporin derivatives was systematically studied. The structure-activity model of cephalosporin derivatives was found: QC8, QC7, dipole had positive correlation on the activities of cephalosporin derivatives.

Key words: Cephalosporin derivative, Quantum chemistry, Density functional method, Quantitave Structure-activity relationship(QSAR)
