The carcinogenic and mutagenic actions of benz(a)pyrene (BP) and its derivatives 6-methyl-, 6-formyl-, 6-chloro-, 6-hydroxy-, 6-acetoxy-, 6-methoxy- and 4(5)-methoxy-BP were studied in mice and bacteria Salmonella typhimurium TA-98 and TA-100, respectively. The potent carcinogenic agents BP, 6-methyl-, 6-formyl-BP proved also mutagenic in bacteria of both strains. Weak carcinogenic compounds (6-chloro-, 6-methoxy-, 4(5)-methoxy-BP) and noncarcinogenic ones (6-acetoxy-, 6-hydroxy-BP) either turned out nonmutagenic or mutagenic in one of two bacterial strains tested. The differences in carcinogenic and mutagenic actions of the substances under study are not relative to the rate of their oxidation in the enzymatic system.

UI	MeSH Term	Description	Entries

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
D009154	Mutation	Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.	Mutations
D002273	Carcinogens	Substances that increase the risk of NEOPLASMS in humans or animals. Both genotoxic chemicals, which affect DNA directly, and nongenotoxic chemicals, which induce neoplasms by other mechanism, are included.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013329	Structure-Activity Relationship	The relationship between the chemical structure of a compound and its biological or pharmacological activity. Compounds are often classed together because they have structural characteristics in common including shape, size, stereochemical arrangement, and distribution of functional groups.
