The mutagenicities of safrole, estragole, eugenol, trans-anethole, and some of their known or possible metabolites for Salmonella typhimurium mutants.
Safrole, estragole, anethole, and eugenol and some of their known or possible metabolites were tested for mutagenic activity for S. typhimurium TA1535, TA100, and TA98. Highly purifiedExpand
Metabolic activation of 9-hydroxymethyl-10-methylanthracene and 1-hydroxymethylpyrene to electrophilic, mutagenic and tumorigenic sulfuric acid esters by rat hepatic sulfotransferase activity.
Our previous studies on 7-hydroxymethyl-12-methylbenz[a]anthracene and 6-hydroxymethylbenzo[a]pyrene showed that cytosolic sulfotransferase activity plays a major role in the formation of hepaticExpand
Isolation and Characterization of a Galactosamine Wall from Spores and Spherules of Physarum polycephalum.
The myxomycete, Physarum polycephalum, can be induced under laboratory conditions to form two different hard-walled forms, spores and spherules. Characterization of both types of walls revealed onlyExpand
Anaphase Delay after Inhibition of Protein Synthesis between Late Prophase and Prometaphase
The relationship between protein synthesis and mitosis was studied in Physarum polycephalum, a plasmodial slime mold whose nuclear divisions are synchronous. Results of studies with actidioneExpand
Isolation and Characterization of an Extracellular Polysaccharide from Physarum polycephalum.
The myxomycetes are called slime molds because of the synthesis of copious amounts of extracellular material (slime) during parts of the life cycle. In Physarum polycephalum, small amounts of slimeExpand
Apurinic/apyrimidinic site induction in supercoiled DNA and mutagenesis in Salmonella typhimurium TA100 by 1'-acetoxysafrole and related electrophilic alkenylbenzene derivatives.
The abilities of seven electrophilic alkenylbenzene derivatives related to 1'-acetoxysafrole to induce apurinic/apyrimidinic (AP) sites in supercoiled SV40 DNA were quantitated by gel electrophoresisExpand
Activation of 1-hydroxymethylpyrene to an electrophilic and mutagenic metabolite by rat hepatic sulfotransferase activity.
Hydroxylation of meso-methyl groups with subsequent formation of reactive benzylic esters bearing a good leaving group (e.g., sulfate, phosphate, acetate, etc.) has been proposed as a possibleExpand
Aminopeptidases of Physarum polycephalum during growth and differentiation.
Abstract A soluble cell fraction from exponentially growing microplasmodia of the slime mold, Physarum polycephalum , contains 12 electrophoretically distinguishable enzymes capable of hydrolyzingExpand
