Cytotoxic effects of the lipophilic iron chelator omadine.

Abstract:

:Cytotoxic effects were observed following 4 h incubation of human leukaemic cells with the iron chelator 1-hydroxypyridine-2-thione (omadine). Its cytotoxic activity was comparable to that of the cytotoxic drug doxorubicin. At the same concentration two other effective iron chelators, desferrioxamine and 1,2-dimethyl-3-hydroxypyrid-4-one, were not cytotoxic. Addition of iron augmented the effect of omadine. It is suggested that the lipophilic properties of omadine and of its iron complex cause their intracellular accumulation and potent cytotoxic activity.

  • The link between restriction endonuclease fidelity and oligomeric state: a study with Bse634I.

    abstract::Type II restriction endonucleases (REases) exist in multiple oligomeric forms. The tetrameric REases have two DNA binding interfaces and must synapse two recognition sites to achieve cleavage. It was hypothesised that binding of two recognition sites by tetrameric enzymes contributes to their fidelity. Here, we experi...
