Resumo
The chalcone (E)-1-(2-hydroxyphenyl)-3-(4-methylphenyl)-prop-2-en-1-one), or 2HMC, displays antileishmanial, antimalarial, and antioxidant activities. The aim of this study was to
investigate the cytotoxic, genotoxic, mutagenic, and protective effects of 2HMC using the
Ames mutagenicity test, the mouse bone marrow micronucleus test, and the comet assay in
mice. In the assessment using the Ames test, 2HMC did not increase the number of His+
revertants in Salmonella typhimurium strains, demonstrating lack of mutagenicity. 2HMC
showed no significant increase in micronucleated polychromatic erythrocyte frequency
(MNPCE) in the micronucleus test, or in DNA strand breaks using the comet assay, evidencing absence of genotoxicity. Regarding cytotoxicity, 2HMC exhibited moderate cytotoxicity in mouse bone marrow cells by micronucleus test. 2HMC showed antimutagenic action
in co-administration with the positive controls, sodium azide (SA) and 4-nitroquinoline-1-
oxide (4NQO), in the Ames test. Co-administered and mainly pre-administered with cyclophosphamide (CPA), 2HMC caused a decrease in the frequency of MNPCE using the
micronucleus test and in DNA strand breaks using the comet assay. Thus, 2HMC exhibited
antimutagenic and antigenotoxic effects, displaying a DNA-protective effect against CPA,
SA, and 4NQO carcinogens. In conclusion, 2HMC presented antimutagenic, antigenotoxic
and moderate cytotoxic effects; therefore it is a promising molecule for cancer prevention.
