BACKGROUND Sulforaphane (SFN) is a potent chemopreventive agent, which is widely consumed in diet or as a diet supplement. It modulates the enzymes of II and III metabolism phase. In this paper, the influence of SFN and three commonly consumed drugs: furosemide, verapamil and ketoprofen on II and III metabolisms phase enzymes was studied. We have also(More)
Porphyrin photosensitizers tend to localize in mitochondria. The depolarization of mitochondrial membrane is one of the early stages of apoptosis and Laser Scanning Fluorescence Microscopy allows to determine changes in transmembrane mitochondrial potential under influence of PDT depending on the kind of photosensitizer (PP(Arg)(2), Hp(Arg)(2)), the energy(More)
Mitochondria are cell energetic centers where ATP is produced. They also play a very important role in the PDT as intracellular sites of photosensitizer localization. Photosensitizers gathering in mitochondria (like porphyrin derivatives used in this work) are more effective in tumor cell destruction. Moreover, it was assumed that di-amino acid substituents(More)
Multiple in vitro tests are widely applied to assess the anticancer activity of new compounds, including their combinations and interactions with other drugs. The MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay is one of the most commonly used assays to assess the efficacy and interactions of anticancer agents. However, it can be(More)
Isothiocyanates, among which alyssin is counted, are the compounds that have proved chemopreventive properties and the ability to induce the 2 and the 3 detoxification phase by affecting the transcription factor nuclear erythroid 2-related factor (Nrf2). Having a positive effect on the human body, these compounds are used as dietary supplements. Because of(More)
