Abstract

In this work the synthesis, structure and certain catalytic properties of amino acid copper complexes covalently grafted onto silica gel are described. The following enzyme mimicking complexes were synthesized and characterised by experimental (FT-IR) and computational (mainly MM+) methods: BOC-His-Cu/silica gel, BOC-Tyr-Cu/silica gel, His-OMe-Cu/silica gel, Tyr-OMe-Cu/silica gel, H-His-Cu/silica gel, H-Tyr-Cu/silica gel His-OH-Cu/silica gel and Tyr-OH-Cu/silica gel. The activities of these substances were also tested in the decomposition of hydrogen peroxide. The majority of the substances proved to be good enzyme mimics displaying either catalase or tyrosinase activity.
