Fluridone

Fluridone is an herbicide. It inhibits phytoene desaturase (Ki = 0.03 µM), an enzyme involved in carotenoid biosynthesis. Fluridone (50 and 100 µM) decreases beta-carotene (Cay-16837) levels and induces accumulation of phytofluene and phytoene in T. aestivum seedlings grown in the dark. It reduces levels of the plant hormone abscisic acid (Cay-10073) in hydrated and dehydrated V. faba leaves when used at a concentration of 10 µM. Fluridone is cytotoxic to the cyanobacterium Anacystis nidulans (LC50 = 0.125 µM) and has acute toxicity against several species of invertebrates and fish (median LC50s = 4.3 and 10.4 mg/L, respectively). Formulations containing fluridone have been used as aquatic herbicides.Formal Name: 1-methyl-3-phenyl-5-[3-(trifluoromethyl)phenyl]-4(1H)-pyridinone. CAS Number: 59756-60-4.
