| 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. |
