Fluridone

一种除草剂；抑制八氢番茄红素去饱和酶(Ki=0.03µM)；在50和100µM浓度下，降低黑暗环境下生长的小麦幼苗中的β-胡萝卜素水平并诱导八氢番茄红素和八氢番茄红素的积累；在10µM浓度下，降低水合和脱水蚕豆叶片中的植物激素脱落酸水平；对蓝藻A.nidulans具有细胞毒性(LC50=0.125µM)；对几种无脊椎动物和鱼类具有急性毒性（中位LC50分别为4.3和10.4mg/L）。An herbicide; inhibits phytoene desaturase (Ki = 0.03 µM); decreases β-carotene levels and induces accumulation of phytofluene and phytoene in T. aestivum seedlings grown in the dark at 50 and 100 µM; reduces the levels of the plant hormone abscisic acid in hydrated and dehydrated V. faba leaves at 10 µM; cytotoxic to the cyanobacterium A. nidulans (LC50 = 0.125 µM); has acute toxicity against several species of invertebrates and fish (median LC50s = 4.3 and 10.4 mg/L, respectively).分子式C19H14F3NO分子量329.3O=C1C(C2=CC=CC=C2)=CN(C)C=C1C3=CC(C(F)(F)F)=CC=C3
