[Inhibition of gamma-amylase of the rabbit liver by biogenic amines and products of their oxidative deamination].

Products of oxidative deamination of biogenic amines (aldehydes) exhibited an inhibitory effect on rabbit liver gamma-amylase activity. The aldehydes, formed after serotonin and 2-phenylethylamine oxidation, proved to be most effective in these systems. Dopamine, noradrenaline and tyramine also caused a slight inhibitory action under these conditions. Biogenic amines and corresponding aldehydes participate apparently in regulation of gamma-amylolysis of glycogen in human and animal organisms.
