These studies indicate the rationality of our molecular design based on the crystal structure of KARI complex. To obtain more KARI inhibitors with high activities, the molecular docking and 3D-QSAR methods were applied to our further studying of these amidine compounds. Two methods AutoDock3. 0.3 and DOCK4. 0 were used in molecular docking, and the calculate results accord with that of herbicidal tests in general. The CoMFA model from 3D-QSAR analysis provided useful guidance for designing highly active compounds prior to their synthesis.
