| Abstract: | Objective To study quantitative structure-activity relationship of emodin derivatives against the cell line of KB. Methods By AM1 method in quantum chemistry, molecular structural parameters of 10 emodin derivatives have been calculated, and the relationship has been established between the activity against the cell line of KB and the molecular parameters by stepwise regression analysis (SRA). Result The QSAR model was established successfully. Conclusion The activity of emodin derivatives against the cell line of KB is related to the hydrophobic parameter, negative charge of A circle and energy of the second low unoccupied molecular orbit. This results are helpful for developing new drug against the cell line of KB. |
