Abstract
The azinomycins are potent antitumour antibiotics that are able to crosslink DNA, but are relatively unstable and unlikely to progress as therapeutic candidates. A prototype analogue 4 with more clinical potential has been designed and synthesised and incorporates the epoxide function of the azinomycins and a nitrogen mustard. Two further analogues 5 and 6 that can alkylate DNA but cannot crosslink the duplex have also been synthesised. Compound 4 crosslinks DNA efficiently at nM concentrations. Compounds 4–6 were submitted to the NCI 60 cell line screen and have similar antitumour activity, although 4 is slightly less active than the non-crosslinking compounds. These observations will be important in the design of further azinomycin analogues with antitumour activity.
