Abstract

The invention discloses a method for taking 3-aryl-5-methyl butyrolactone compound as acetylglucosyl bromide, and relates to the acetylglucosyl bromide prepared from a chemical compound. The method comprises a method for resisting the activity of tobacco mosaic viruses, a method for killing the activity of funguses in vitro and a method for killing the activity of the funguses in vivo. The suppression rate of (Ia-1)-(Ia-9) and (Ib-1)-(Ib-9) in the 3-aryl-5-methyl butyrolactone compound to the tobacco mosaic viruses is over 60 percent under the concentration of 500 mu g/mL, and the 3-aryl-5-methyl butyrolactone compound is high in the fungicidal activity to 14 funguses. Compared with the prior art, the method disclosed by the invention has an obvious progress and extremely outstanding economical benefits.

Description

technical field [0001] The technical scheme of the present invention relates to the anti-plant virus agent of chemical compound, specifically the method that 3-aryl-5-methylbutyrolactone compound is used as anti-plant virus agent. Background technique [0002] The skeleton structure of butyrolactone widely exists in natural products and drug molecules. 3-(4-methylphenyl)-5-ethyl-2,5-dihydrofuran-2-one (Incrustoporin) was first isolated from the tree basidiomycete Incrustoporia carneola9170 (Zapf, S.; AnkeT. ; Sterner, O.Acta.chem.scand.1995,49,233–234.), biological activity research found that it has certain antibacterial activity and cytotoxicity. The bactericidal activity was evaluated by the agar diffusion method in vitro test mode. The test objects were: Absidia glauca (+) (grey green Absidia), Absidia glauca (–), Aspergillus ochraceus (ochrax), Cladosporium cladosporioides (black mold), Curvularia lunata(Curvularia lunata),Fusarium oxysporum(Fusarium oxysporum),Fusari...
