Enhanced catalase-like activity of manganese salen complexes in water: effect of a three-dimensionally fixed auxiliary

摘要

A new Mn(Salen) complex bearing an ureido group as an auxiliary that is three-dimensionally fixed by a cyclopentane ring fused to the Salen structure was developed. This compound exhibited considerably higher catalase-like activity than the original Mn(Salen), i.e., the cyclopentane-fused Mn(Salen) without the auxiliary, under near-physiological conditions.
