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.

这些分子作为潜在的KARI抑制剂为基于KARI的农药分子设计提供了有利指导；对部分小分子进行了合成，在除草活性初筛的近三十个化合物中，个别化合物表现出较好的除草活性，其中一个化合物wb1596对油菜和稗草具有较高的生长抑制率，并通过E.coli KARI酶活性抑制试验验证了其KARI酶的作用靶标，此化合物可以作为KARI一个有苗头的抑制剂为后续工作奠定了基础；对发现的有苗头的KARI抑制剂进行了结构修饰和优化，合成了一系列脒类化合物并确证了它们的结构，改造后的化合物与原抑制剂相比大多除草活性相当或更佳，从而表明我们基于靶标结构的分子设计的合理可靠性；对所合成一系列脒类化合物进行了分子对接和三维定量构效关系研究。
