Sequence-specific polyamides that bind in the minor groove of DNA are attractive candidates for antibiotics, cancer chemotherapeutics, and transcriptional antagonists. This paper reviews the progress of structure-based design of minor-groove-hinding polyamides, from the first structure of netropsin with DNA, to the effective linked polyamides currently under study. A theory of polyamide specificity is also reviewed, introducing methods to determine the optimal strategies for targeting a given DNA sequence within a genome of competing sequences.
