Özet
4-Thujanol (sabinene hydrate), a bicyclic monoterpene alcohol, is found in the essential oils of many aromatic and medicinal plants and is widely used as a fragrance and flavouring agent in many different products. The aim of this study was to evaluate the protective effects of 4-thujanol against the genotoxic effects induced by mitomycin C (MMC) and cyclophosphamide (CP) in human lymphocytes, using the chromosome aberrations, sister chromatid exchanges, and micronucleus tests, in the absence and in the presence of S9 mix, respectively. The cells were treated with 0.25 mu g/mL MMC and 28 mu g/mL CP as alone and cotreated with 13 + 0.25, 26 + 0.25, and 52 + 0.25 mu g/mL 4-thujanol + MMC and with 13 + 28, 26 + 28, and 52 + 28 mu g/mL 4-thujanol + CP as a mixture. The present study showed that 4-thujanol was unable to reduce the genetic damage induced by MMC, in the absence of S9 mix. On the other hand, probably the metabolites of 4-thujanol act as an antagonist and markedly antagonize CP-induced genotoxicity, in the presence of S9 mix. In general, 4-thujanol + MMC and 4-thujanol + CP decreased the mitotic index, proliferation index and nuclear division index to the same extent or more than those of individual exposure of MMC or CP. In conclusion, 4-thujanol significantly reduced (p < 0.001) the genotoxic damage induced by CP but not MMC when compared with the respective positive control alone. We can suggest that 4-thujanol may improve the chemopreventive effects and may also reduce the harmful side effects of CP, which is widely used in chemotherapy against cancer, without reducing its anti-proliferative activities.
