animals. To discover novel natural-product-based herbicides, a series of N-(arylmethoxy)-2-chloronicotinamides were designed and synthesized. Some of the new N-(arylmethoxy)-2-chloronicotinamides exhibited excellent herbicidal activity against Agrostis stolonifera (bentgrass) at 100 μM. Compound 5f (2-chloro-N-((3,4-dichlorobenzyl)oxy)nicotinamide) possessed excellent herbicidal activity against Lemna paucicostata
烟酸又称烟酸,是一种天然产物,广泛存在于动植物中。为了发现基于天然产物的新型除草剂,设计并合成了一系列N- (芳基甲氧基)-2-氯代烟酰胺。一些新的N -(芳基甲氧基)-2-氯烟酰胺在 100 μM 时对Agrostis stolonifera(蓼蒿)表现出优异的除草活性。化合物5F(2-氯- ñ - ((3,4-二氯苄基)氧基)烟酰胺)具有优良的除草活性对青萍(浮萍),与IC 50值 7.8 μM,而商业除草剂异恶草酮和丙苯腈的值分别为 125 和 2 μM。本文报道的构效关系可用于开发抗单子叶杂草的新型除草剂。
