Design, synthesis, and intracellular localization of a fluorescently labeled DNA binding polyamide related to the antibiotic distamycin

The design and synthesis of the lipophilic (9) and fluorescent (10) conjugates of a structural analogue of distamycin and their in vitro cellular localization studies are reported. Confocal laser scanning microscopy (CLSM) indicates that 10 rapidly enters human ovarian adenocarcinoma (SKOV-3) cells with principal uptake in mitochondria and uniform cytoplasmic distribution.
