The significant contents of artepillin C (AC) in green propolis have prompted research on the biological activities of the compound. The present study evaluated the activity of this phenolic compound on DNA, assessing its genotoxic and antigenotoxic potentials in the somatic mutation and recombination test in Drosophila melanogaster. The standard (ST) and high-bioactivation (HB) crosses were used in the assessment of genotoxic potential, since they express cytochrome P450 metabolization enzymes differently. In the 0.1-1.6 mM concentration range, AC did not have any genotoxic action in either cross. Antigenotoxic potential was investigated using the ST cross. In co- and post-treatment protocols, AC 0.4, 0.8, and 1.6 mM did not modulate mutagenic action of ethyl methanesulphonate. However, though it did not influence the frequency of damage induced by mitomycin C in co-treatment, AC reduced genotoxicity of the mutagen when administered after damage, but only at 0.4 mM. This modulation is associated with the reduction of genetic damage caused by recombinational events. The results of the present study and literature findings indicate that the various responses elicited by AC, namely induction of DNA damage, production of genetic lesions, or activation of DNA repair mechanisms are functions of AC concentration.

D004249 DNA Damage Injuries to DNA that introduce deviations from its normal, intact structure and which may, if left unrepaired, result in a MUTATION or a block of DNA REPLICATION. These deviations may be caused by physical or chemical agents and occur by natural or unnatural, introduced circumstances. They include the introduction of illegitimate bases during replication or by deamination or other modification of bases; the loss of a base from the DNA backbone leaving an abasic site; single-strand breaks; double strand breaks; and intrastrand (PYRIMIDINE DIMERS) or interstrand crosslinking. Damage can often be repaired (DNA REPAIR). If the damage is extensive, it can induce APOPTOSIS. DNA Injury,DNA Lesion,DNA Lesions,Genotoxic Stress,Stress, Genotoxic,Injury, DNA,DNA Injuries
