Redox activation of Fe(III)-thiosemicarbazones and Fe(III)-bleomycin by thioredoxin reductase: specificity of enzymatic redox centers and analysis of reactive species formation by ESR spin trapping

Thiosemicarbazones such as triapine (Tp) and Dp44mT are tridentate iron (Fe) chelators that have well-documented anti-neoplastic activity. While Fe-thiosemicarbazones can undergo redox-cycling to generate reactive species that may have important roles in their cytotoxicity, there is only limited ins...
