Sažetak
A series of new diamidino, diisopropylamidino and diimidazolinyl substituted derivatives of phenyl-benzothiazolyl- and dibenzothiazolyl-furans and -thiophenes were successfully prepared and evaluated for their antiproliferative activity on tumour cell lines in vitro, DNA binding propensity and sequence-selectivity as well as cellular distribution. A strong antiproliferative effect of the tested compounds was observed on all tested cell lines in a concentration-dependent response pattern. In general, imidazolinyl-substituded derivatives and/or the thiophene core were in correlation with increased antiproliferative activity. Two compounds (2b and 3b) were chosen for biological studies due to their differential antiproliferative properties. The DNA binding properties of this new series of compounds were assessed and evidenced their efficient minor groove binding properties with preferential interaction at AT-rich sites. Both compounds also present nuclear sub-cellular localization, suggesting that their cellular mode of action implies localization in the DNA compartment and direct inhibition of DNA replication and induction of apoptosis.
