Abstract
Riboflavin (RF), vitamin B2 and anthracyclines, daunorubicin (DAU) and doxorubicin (DOX) showed the influence on electrochemical and spectral properties of the DNA molecule. The interactions were analysed using voltammetry, UV/VIS absorbance spectrophotometry and circular dichroism spectroscopy. These interactions were investigated by monitoring changes: in electrochemical properties of ctDNA and oligonucleotides interacting with RF on the surface of screen-printed carbon electrode (SPCE) surface using square-wave voltammetry (SWV), in UV/VIS absorption spectra of ctDNA, oligonucleotides and RF and in circular dichroism spectra of DNA in increasing concentration of RF and anthracyclines. The obtained results indicate that interactions between investigated compounds and DNA depend on the DNA sequence and the concentration of ligand. As the result of interactions, oxidation signals of guanine and adenine, absorbance spectra of DNA and RF, and CD spectra of oligonucleotides changes. RF binding to DNA causes decrease in number of exposed oxidative functional groups proved by decrease in oxidation signal of bases and lowered absorbance signal of DNA and RF mixture. CD investigations showed the influence of RF and anthracyclines on the DNA conformation. RF showed preference on AT regions while anthracyclines bind on different way in different DNA regions depending on concentration. At lower concentrations, they intercalate to GC and bind to the groove of AT regions while higher concentration induces conformational changes to Z-DNA.
Abstract (croatian)
Riboflavin, vitamin B2 i antraciklini, daunorubicin (DAU) i doksorubicin (DOX) su pokazali utjecaj na elektrokemijska i spektralna svojstva DNA molekule. Interakcije su analizirane pomoću voltametrije, UV/VIS apsorpcijske spektrofotometrije i cirkularni dikroizam spektroskopije. Interakcije su analizirane praćenjem promjena u: elektrokemijskim svojstvima ctDNA i oligonukleotida u interakciji s RF na površini tiskane ugljikove electrode (SPCE) upotrebom kvadratno-valne voltametrije (SWV), UV/VIS apsorpcijskim spektrima ctDNA, oligonukleotida i RF te DNA spektru cirkularnog dikroizma u povećanju koncentracije RF i antraciklina. Dobiveni rezultati pokazuju da interakcije između DNA i ispitivanih spojeva ovise o slijedu DNA i koncentraciji liganda. Kao rezultat interakcija, mijenjaju se oksidacijski signali gvanina i adenine, apsorpcijski spektri DNA i RF te CD spektri oligonukleotida. Vezanje RF na DNA uzrokuje smanjenje broja izloženih oksidacijskih funkcionalnih skupina što je dokazano smanjenjem oksidacijskih signala baza te sniženim apsorcijskim signalom smjese DNA i RF. CD ispitivanja su pokazala utjecaj RF i antraciklina na DNA konformaciju. RF je pokazao veći afinitet prema AT regijama dok se antraciklini vežu na različite načine u različitim područjima DNA, ovisno o koncentraciji. Pri nižim koncentracijama, interkaliraju se na GC i vežu na utor AT regije, dok veća koncentracija izaziva konformacijske promjene u Z-DNA.
