The results showed that the contributions of steric and electrostatic fields to the activity were 47.5% and 52.5%, respectively. The coefficient q2 of cross validation and the relation coefficient r2 of non-cross validation for the model established by the study were 0.628 and 0.971, respectively, its F value was 133.840 and the standard deviation was 0.109. These values indicated that the model might have a good predictability. The contour maps of the model will give the basis on the structure modification.展开更多
