In the forth chapter, the mechanism of pyrimidine benzylamine compounds is studied by the conventional bioassay and biochemical methods based on probe compound 104-4. The results presented here indicated that the addition of 5 mg/L of 3 branched-amino acids to sorghum seedling cultures incubated in the presence of 104-4 completely alleviated herbicide-induced stem growth inhibition, but each of Val, Ile and Leu single is only partly effective in reversing 104-4-induced growth inhibition at the same concentrations.

通过先导结构优化策略的实施，筛选出15个高除草活性的4，6-二甲氧基-2-取代嘧啶苄胺类候选化合物，在此基础上，对一些候选化合物进行作物安全性评价试验，实验结果提示化合物103-1和化合物105-3在低剂量下对某些作物有良好的选择性，可作为优选化合物进入田间小区试验。

The results of bioassay suggest that 2-methylthio-6-methyl-4-substituted pyrimidine and 4, 6-dimethoxy-2-substituted pyrimidine derivatives show herbicidal activity. In these target compounds, 4, 6-dimethoxy-2-substituted pyrimidine benzylamine and 4, 6-dimethoxy-2-Substituted pyrimidine benzylidene amine exhibit good herbicidal activity, and the herbicidal will be affected by the substituents in the benzene ring.

对分子库中的目标分子进行了生物活性筛选研究，发现其中的2-甲硫基-6-甲基-4-取代嘧啶衍生物和4，6-二甲氧基-2-取代嘧啶类化合物显示出除草活性，其中4，6-二甲氧基-2-取代嘧啶苄胺类化合物和4，6-二甲氧基-2-取代嘧啶亚苄胺类化合物具有较好的除草活性，而且其活性和苯环上的取代基有关。
