Fe(II)-Bleomycin is activated in air to form an electron paramagnetic resonance (EPR)-active species, termed "activated bleomycin", that cleaves DNA, when present. When DNA is absent, the potential DNA cleavage activity is lost and the drug becomes self inactivated. A method is described for the preparation and purification of this self-inactivated product from bleomycin A2, together with some ...
We have previously proposed that the BlmIV and BlmIII non-ribosomal peptide synthetases are involved in the formation of the bithiazole moiety of the anti-tumor drug bleomycin in Streptomyces verticillus ATCC15003. We report here the identification and characterization of an oxidation domain in BlmIII. The oxidation domain shows local homology to a family of oxidoreductases and is present in al...
Bacterial DNA gyrase is a well-established and validated target for the development of novel antibacterials. Starting from the available structural information about the binding of the natural product inhibitor, clorobiocin, we identified a novel series of 4'-methyl-N(2)-phenyl-[4,5'-bithiazole]-2,2'-diamine inhibitors of gyrase B with a low micromolar inhibitory activity by implementing a two-...
