Increased frequency of sister-chromatid exchange induced by dothistromin in CHO cells and human lymphocytes
Autor: Jenny Wang, Albert Stoessl, Leo Skinnider
Publikováno v: Mutation Research/Genetic Toxicology. 222:167-170
Dothistromin is a metabolite produced by Dothistromin pini and Cercospora arachidicola. The latter fungus is a pathogen of the peanuts and thus the mycotoxin may be a contaminant of foodstuffs. Dothistromin induces a dose-dependent increase in sister

Biosynthesis of antifungal stress metabolites from potato: observation of hydride shifts via the 'β-hop' from incorporation of [2-2H3,2-13C]acetate and 13Cmr
Autor: J. B. Stothers, Albert Stoessl
Publikováno v: Canadian Journal of Chemistry. 61:1766-1770
The proposed migration of hydrogen from C-5 to C-4 in the biosynthesis of the potato phytoalexins lubimin (2). rishitin (5), and 3-hydroxylubimin (6) has been studied by incorporation of [2-2H3,2-13C]acetate. Direct observation of the predicted β-sh

Alternaric acid. Proof of biosynthesis via condensation of two polyketide chains. Complete assignment of the 1H and 13C magnetic resonance spectra by 2D techniques
Autor: J. B. Stothers, Albert Stoessl
Publikováno v: Canadian Journal of Chemistry. 62:549-553
Incorporation studies utilizing [1,2-13C2]acetate have established that the fungal phytotoxin alternaric acid is biosynthesized by an uncommon condensation of two polyketide chains rather than from a single chain undergoing an a priori possible, albe

Dothistromin as a metabolite of Cercospora arachidicola
Autor: Albert Stoessl
Publikováno v: Mycopathologia. 86:165-168
The known phytotoxin dothistromin has been newly identified as a metabolite of the peanut pathogen Cercospora arachidicola. The potential of the substance as a mycotoxin is discussed.

Sesquiterpenoid stress compounds of the solanaceae
Autor: E. W. B. Ward, J.B. Stothers, Albert Stoessl
Publikováno v: Phytochemistry. 15:855-872
The sesquiterpenes isolated from species of the Solanaceae under various conditions of stress are reviewed, with brief references to other solanaceous stress metabolites. The chemistry and selected physical properties of the sesquiterpenoidal compoun

Publikováno v: Canadian Journal of Chemistry. 52:993-1005
To define the stereochemistry of capsidiol (1), an antifungal sesquiterpene isolated from sweet peppers, a detailed 13C n.m.r. investigation was carried out. From the results for 1 and a series of its derivatives (2–6) compared with those for sever

A carbon-13 biosynthetic study of stress metabolites from carrot roots: eugenin and 6-methoxymellein
Autor: J. B. Stothers, Albert Stoessl
Publikováno v: Canadian Journal of Botany. 56:2589-2593
Sodium [1,2-13C2]acetate was readily incorporated into the stress compounds 6-methoxymellein (I) and eugenin (III) after their formation in carrot roots had been induced by treatment with ethrel. The complete incorporation patterns were revealed by 1
