Application

Syringaldazine has been used as a substrate to measure the enzymatic activity of recombinant laccase.

Actions biochimiques/physiologiques

Syringaldazine (4-Hydroxy-3, 5-dimethoxybenzaldehyde azine) is a nonautooxidizable laccase-specific compound. It acts as a substrate for laccase and peroxidase in the presence of hydrogen peroxide (H2O2). Syringaldazine also acts as an electron donor in the prostaglandin H synthase (PGHS) reaction.
