Insight into the Complexation Mode of Bis(nitrilotriacetic acid) (NTA) Ligands with Ni<sup>2+</sup>Involved in the Labeling of Histidine-Tagged Proteins
Herein, we present a rational explanation for the observed stability of the ternarycomplex involving the postulated bis‐NTA–(Ni2+)2 species and multivalent polyhistidine tags. We have found that prior to the formation of the ternarycomplex, the Ni2+‐preloading step of bis‐NTA ligands does not form the expected bis‐NTA–(Ni2+)2 exclusively. Instead of the major formation of bis‐NTA–(Ni2+)2 species

Bleomycin mimics: Efficient oxidative double‐strand DNAcleavage has been achieved with multinuclear non‐heme ironcomplexes (see scheme). These complexes therefore represent model compounds that mimic the mode of action of the anti‐tumor drug bleomycin.
