Full textThe discovery of mauveine, by William Perkin in 1856, marked the synthesis of the dye industry. Since then, cyanines have been synthesized with different purposes in particular as photographic sensitizers. Possible applications in the medicine have been intensively studied, as for example the treatment of tumor tissues with the aid of photodynamic therapy, suggesting that there is a predominant action in the production of reactive oxygen species, inducing oxidative stress on cells cancer. Glutathione S-transferases constitute a super-family of ubiquitous, multifunctional enzymes, which play a central role in cell response to the oxidative stress and are considered detoxification enzymes. The enzymes involved in the detoxification may play a significant role in cancer susceptibility. Some polymorphisms present in glutathione S-transferases, GSTM1 and GSTT1 genes, appear to be a risk factor and have been linked to an increased susceptibility to breast cancer. The aim of this study was to perform a preliminary study on the effects of thiacarbocyanines with N-alkyl chain in human cells. For such, was used an assay for studying cell viability (MTT assay) and analyzed, GSTM1 and GSTT1 genes expression by real time PCR in the epithelial cells with breast carcinoma (MCF-7), and in normal human dermal fibroblasts (NHDF) after incubation and recovery with the test compounds. The results showed that the thiacarbocyanines studied with N-alkyl chain demonstrated higher toxicity in MCF-7 cell line comparing to NHDF. These cyanines have also showed a possible mechanism of toxicity, involving processes that promote oxidative stress to cells.
