Using a series of synthetic azinomycin analogues, it is shown that the efficiency of in vitro DNA interstrand cross-linking is markedly reduced when either the C-5' methyl group or both the C-5' methyl and C-3' methoxy groups are deleted from the naphthalene ring.

A series of compounds related to the left-hand domain of the azinomycins have been made and evaluated for cytotoxic activity against a small panel of human tumour cell lines. The epoxide ring is shown to be essential for biological activity. Cytotoxicity is also shown to be sensitive to changes in the substitution pattern on the aromatic ring and the amide group.
