[Development research on oxidase functional model iron complexes].

This paper describes research performed in the Laboratory of Organic Chemistry, Showa Pharmaceutical University. Oxidation reactions involving the oxidase can be divided roughly into two kinds of reactions: The first involves electron removal from an aromatic ring or an active CH-bond. The other reaction involves hydrogen abstraction from an inactive CH-bond. The oxidase models, Fe(DMF)(3)Cl(2)(1+) and Fe(AN)(6)(3+)/AN, which we have synthesized, have been shown to work by the former mechanism, and the models Fe(AN)(6)(3+)-IO(4)(-)/AN, Fe(AN)(6)(2+)-Ac(2)O-H(2)O(2)/AN, Fe(AN)(6)(2+)-2PAH-5Py-Ac(2)O-H(2)O(2)/AN, Fe(PA)(3)(OH(2))-H(2)O(2)/AN and Fe(PA)(3)(OH(2))-O(2)-electrolysis/AN do so by the latter mechanism. Further, we found some iron (II or III)picolinate-H(2)O(2)/AN complexes have the 7 alpha-hydroxylase-like activity.
