This invention pertains to novel protocols for the screening and rapid identification of compounds that specifically inhibit a predetermined enzyme or metabolic target site or pathway that is specific to plants. Enzymes which are specifically or indirected affected by the novel screens include glutamine synthetase (GS), 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase (DAHP), dihydrodipicolinate synthase (DHPS), acetohydroxyacid synthase (AHAS) and phosphoribosyl anthranilate transferase (PAT). The enzymatic pathways targeted by the novel screening protocols are unique to plants, bacteria and fungi and are present at low levels. Thus, inhibiting these enzymes should present little or no toxicity to humans or animals. The screens provide an efficient and rapid method for assessing the herbicidal potential of test compounds. Lead compounds identified by the novel screening protocols can be used as herbicides to inhibit growth.
本发明涉及筛选和快速鉴定特异性抑制植物特有的预定酶或代谢靶点或途径的化合物的新方案。新型筛选方法特异或间接影响的酶包括谷氨酰胺合成酶 (GS)、3-脱氧-D-阿拉伯比诺-庚酮酸 7-磷酸合成酶 (DAHP)、二氢二环戊二酸合成酶 (DHPS)、乙酰羟基酸合成酶 (AHAS) 和磷酸核糖基蒽醌转移酶 (PAT)。新型筛选方案所针对的酶途径是植物、细菌和真菌所独有的,而且含量较低。因此,抑制这些酶应该对人类或动物几乎没有毒性。这些筛选为评估试验化合物的除草潜力提供了一种高效、快速的方法。通过新型筛选方案确定的先导化合物可用作抑制生长的除草剂。
