Highly efficient catalase activity of metallocorroles.

The iron(iii) complex of a bipolar and amphiphilic corrole, which binds strongly to proteins and undergoes protein-mediated cellular uptake, catalyzes the decomposition of hydrogen peroxide faster (k(cat) = 6400 M(-1) s(-1)) and more efficiently (turnover frequency >120 s(-1)) than previously reported synthetic compounds with catalase-like activity.
