Chemistry and Pharmacology
The decomposition reaction of hydrogen peroxide was carried out by using Fe(III)-3,4,3′,4′,3″,4″,3″′,4″′-octacarboxyphthalocyanine (Fe(III)-oaPc) as a catalyst, which has previously been reported by Boston et al. Fe(III)-oaPc is a remarkably effective catalyst for the reaction, compared with hemin, other metal-phthalocyanine compounds, or other iron complexes such as [Fe(III)-(bipy)3]X3. The kinetics of this reaction was also investigated in the pH range 5,5 - 10,5 by measuring the initial velocity, V0, of the increasing concentration of O2 using a Warburg respirometer. The reaction proceeds according the catalase-like mechanism. On the basis of the results of Sigel et al., the reaction mechanism is discussed.
