Electrochemical study of doxorubicin interaction with different sequences of single stranded oligonucleotides, Part I

Popis výsledku v původním jazyce

Doxorubicin is a known anticancer drug intercalating into dsDNA. The mechanism of interaction of doxorubicin with ssDNA is not clear. In this study, adsorptive transfer stripping technique coupled with square wave voltammetry was used for studying of interaction of doxorubicin with single stranded oligonucleotides (ssODN) in various ratios (1:1, 1:2 and 1:5) and interaction times (0-300 min.). When comparing the results for three ratios of the mixture between drug and ssODN we found that the interval ofpeak intensities of oligonucleotide reduced with the increasing ratio of oligonucleotide-doxorubicin, i.e. for ratio 1:1 it is 25-85 %, for ratio 1:2 it is 16-60 % and for ratio 1:5 it is 19-51 %. The interval of relative signal intensities of doxorubicin ranges from 8 to 100 % for ratio 1:1, 22-100 % for ratios 1:2 and 1:5. The results showed the assumption that DOXO peak height increased with increasing concentration of the drug intercalated into ssODN, but the signals CA peaks change
