The effect of oxidation of the sulfur atom on the mutagenicity of ethylenethiourea. 1982

K Autio, and A von Wright, and H Pyysalo

Ethylenethiourea is metabolized in mice by oxidation of the sulfur atom to form 2-imidazolin-2-yl sulfenate. Ethylenethiourea itself is a carcinogen, goitrogen, teratogen and a weak bacterial mutagen. The mutagenicities of ethylenethiourea, 2-imidazolin-2-yl sulfenate and their nitroso derivatives were compared in direct bacterial tests and in the host-mediated assay. In all the test systems applied, 2-imidazolin-2-yl sulfenate was less mutagenic than the parent compound.

D009153 Mutagens Chemical agents that increase the rate of genetic mutation by interfering with the function of nucleic acids. A clastogen is a specific mutagen that causes breaks in chromosomes. Clastogen,Clastogens,Genotoxin,Genotoxins,Mutagen
D010084 Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Redox,Oxidation Reduction
D005031 Ethylenethiourea A degradation product of ethylenebis(dithiocarbamate) fungicides. It has been found to be carcinogenic and to cause THYROID hyperplasia. Imidazolidinethione,2-Mercaptoimidazoline,Imidazolidine-2-thione,2 Mercaptoimidazoline
D012486 Salmonella typhimurium A serotype of Salmonella enterica that is a frequent agent of Salmonella gastroenteritis in humans. It also causes PARATYPHOID FEVER. Salmonella typhimurium LT2
D013455 Sulfur An element that is a member of the chalcogen family. It has an atomic symbol S, atomic number 16, and atomic weight [32.059; 32.076]. It is found in the amino acids cysteine and methionine. Sulfur-16,Sulfur 16
