Recently I am researching about GLUTATHIONE-S-TRANSFERASE; HELICOVERPA-ARMIGERA; MIDGUT; RESISTANCE; ECOLOGY; TANNINS; PH, Saw an article supported by the NSERCNatural Sciences and Engineering Research Council of Canada (NSERC) [RGPIN/250173-2002]; FQRNT Amenagement et Environnement Forestiers V grant [186342]; Concordia University Dean’s Award of Excellence. Published in PUBLIC LIBRARY SCIENCE in SAN FRANCISCO ,Authors: Donkor, D; Mirzahosseini, Z; Bede, J; Bauce, E; Despland, E. The CAS is 99-93-4. Through research, I have a further understanding and discovery of 4′-Hydroxyacetophenone. Formula: C8H8O2
This study examines the post-ingestive fate of two host-plant derived small-molecule phenolics (the acetophenones piceol and pungenol) that have previously been shown to be toxic to the outbreaking forest pest, spruce budworm (Choristoneura fumiferana). We test first whether these compounds are transformed during passage through the midgut, and second whether the budworm upregulates activity of the detoxification enzyme glutathione-s-transferase (GST) in response to feeding on these compounds. Insects were reared on either foliage or artificial diet to the fourth instar, when they were transferred individually to one of two treatment diets, either control or phenolic-laced, for approximately 10 days, after which midguts were dissected out and used for Bradford soluble protein and GST enzyme activity analysis. Frass was collected and subjected to HPLC-DAD-MS. HPLC showed that the acetophenones do not autoxidize under midgut pH conditions, but that glucose- and glutathione-conjugates are present in the frass of insects fed the phenolic-laced diet. GST enzyme activity increases in insects fed the phenolic-laced diet, in both neutral pH and alkaline assays. These data show that the spruce budwom exhibits counter-adaptations to plant phenolics similar to those seen in angiosperm feeders, upregulating an important detoxifying enzyme (GST) and partially conjugating these acetophenones prior to elimination, but that these counter-measures are not totally effective at mitigating toxic effects of the ingested compounds in the context of our artifical-diet based laboratory experiment.
Formula: C8H8O2. Bye, fridends, I hope you can learn more about C8H8O2, If you have any questions, you can browse other blog as well. See you lster.
