The research focuses on developing new DNA-binding ligands modeled after Chromomycin A3 (CRA3), a potent antitumor antibiotic known for binding in the minor groove of GC-rich regions of duplex DNA. The new ligands were designed to mimic CRA3's structure, particularly its trisaccharide part, using a simple alkyl group attached to the chromophore. The study successfully demonstrated that these new ligands form Mg2+-coordinated dimer complexes, exhibiting DNA-binding affinity. The synthesis involved several steps, including [4+2] cycloaddition, aldol reaction, deprotection, dehydroxylation, and hydrogenation. The ligands' Mg2+-binding properties were investigated using UV spectra, and their DNA-binding affinity was evaluated through a competitive displacement assay with ethidium bromide (ETBr) and self-complementary DNA duplexes. The experiments showed that the alkyl chain in the new ligands contributes significantly to the formation of dimer complexes and DNA binding, with the 3(S) isomer showing high affinity to DNA in the presence of MgCl2. The study concluded that the simple alkyl chain can mimic some roles of the trisaccharide part for Mg2+-dimer complex formation and Mg2+-mediated DNA binding, and further efforts are underway to develop stronger DNA-binding ligands based on this model.
The study focuses on the synthesis and biological evaluation of eight distamycin analogues, which are potential anticancer agents designed to bind to the minor groove of B-DNA. These analogues were tested for their in-vitro cytotoxicity against human breast cancer cell lines MCF-7 and MDA-MB-231. The chemicals used in the study include distamycin analogues (compounds 1–8), ethidium bromide for DNA binding assays, and topoisomerase I and II enzymes for assessing the compounds' inhibitory activity. The purpose of these chemicals was to evaluate the analogues' antiproliferative and cytotoxic effects, their interaction with DNA, and their potential to inhibit DNA topoisomerases, which are key enzymes in cellular processes and targets for anticancer drug development. The study aimed to identify potential new anticancer agents with strong cytotoxic effects and DNA binding capabilities.
