The relationships for the two benzoquinone
adducts show greater concavity than that of BO-Alb.
In conclusion we have shown that atrovirinone, a naturally-occuring benzoquinone
from the roots of G.
Past several years, over 78 compounds have been isolated and identified form Antrodia cinnamomea, consisting of zhankuic acids, terpenoids, triterpenes, benzenoids, lignans, benzoquinone
derivatives, succinic and maleic derivatives, and polysaccharides (Geethangili and Tzeng 2009).
A novel chlorinated benzoquinone
antibiotic, mycenon (13), was isolated from the culture broth of a basidiomycete, Mycelia sp.
Chemical defense in harvestmen (Arachnida, Opiliones): do benzoquinone
secretions deter invertebrate and vertebrate predators?
Other pieces were etched in dichloromethane--a good solvent for the reactants--with 1% benzoquinone
for 10 hrs to dissolve any soluble materials.
1996 (a)DIMBOA = 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3- one; gramine = N,N-dimethyl- 3-aminomethylindole; hordenie = 4-(2-dimethylam inoethyl)phenol; scopoletin = 6-methoxy-7-hydroxycoumarin; sorgoleone = 2- hydroxy-5-methoxy-3[8'Z,11' Z)-8',11',14'-pentadecatrienyl]-p- benzoquinone
as the model toxicant, Mason and Liebler (2000) observed cysteine as a preferred target for quinone-induced toxicity.
