Hairpin polyamide-chlorambucil conjugates containing an alpha-diaminobutyric acid (alpha-DABA) turn moiety are compared to their constitutional isomers containing the well-characterized gamma-DABA turn. Although the DNA-binding properties of unconjugated polyamides are similar, the alpha-DABA conjugates display increased alkylation specificity and decreased rate
