The binding of three analogues of the minor-groove binding antiviral antibiotic distamycin (Dst) with double-stranded (ds)-DNA were monitored using ds-DNA melting temperature (Tm) measurements, ethidium bromide (EtBr) displacement assay, footprinting analysis and induced circular dichroism (ICD). These compounds contained 3-5
