Sažetak
Studied dicationic dibenzotetraaza[14]annulene derivatives intercalate into synthetic double stranded DNA and RNA, while their positively charged side-chains additionally interact within the minor groove of polynucleotides, contributing to the overall affinity of compounds and controlling pronounced A-T(U) over G-C sequence preference as well as stronger thermal stabilization of ds-DNA than ds-RNA. Furthermore, all compounds showed moderate to high antiproliferative activity against five human tumour cell lines, whereby clear correlation between structure of the side-chain and cytotoxic activity was observed.
