Abstract
In our previous reports, aspirin, an antipyretic analgesic, suppressed the genotoxicity of mitomycin C (MMC) in a somatic mutation and recombination test (SMART) in Drosophila melanogaster. In order to reveal the mechanism of the anti-genotoxicity of aspirin, we evaluated the suppressing ability of each aspirin metabolite, such as salicylic acid (SA), salicyluric acid (SUA), gentisic acid (GA), gentisuric acid (GUA), and 2,3-dihydroxybenzoic acid (DHBA), in SMART in Drosophila melanogaster using the cotreatment protocol in this report. SUA, GA, GUA, and DHBA reduced the number of the three types of spot induced by MMC without decrease of survival. These aspirin metabolites decreased the genotoxicity frequency of MMC for total spots in a dose-dependent manner. Furthermore, each metabolite decreased the genotoxicity frequency of MMC by approximately 80% at a dose of 40 mg/bottle, respectively. It is suggested that these metabolites are the main substances of anti-genotoxicity in the aspirin metabolic pathway.Keywords
