Sobre IBD

A eficiência e a seletividade das metaloenzimas contendo cobre na oxidação do catecol em o-quinona pelo oxigénio atmosférico levou os químicos de coordenação a investigar as propriedades estruturais e catalíticas destas enzimas. Este trabalho centra-se na síntese de novos ligandos e complexos baseados em estruturas de pirazol. Estes compostos foram estudados pelas suas propriedades catalíticas na catalisação das reacções de oxidação de catecóis e fenóis a o-quinonas e de 2-aminofenol a 2-aminofenoxazinona.O objetivo destes estudos é encontrar melhores modelos para o desenvolvimento da atividade catalítica das enzimas (catecolase, tirosinase e fenoxazinona sintase), através da síntese de novos complexos e de outros complexos preparados in situ por derivados de pirazol em associação com metais de transição. Verificou-se que alguns destes complexos possuem uma excelente atividade catalítica para estas reacções.
