Conditions:

Homoveratrylamine (3,4-dimethoxyphenethylamine, DMPEA) is an analog of the major neurotransmitter dopamine where 3- and 4- position hydroxyl groups are replaced with methoxy groups. DMPEA is a metabolite of dopamine and is reported to be produced at elevated levels in patients with schizophrenia and Parkinson's disease. DMPEA inhibited monoamine oxidase and demonstrated no peripheral and central antidopaminergic activity in vivo.

Conditions:

3, 4-dihydroxyphenylacetic acid (DOPAC) is a neuronal metabolite of dopamine (DA). DA undergoes monoamine oxidase-catalyzed oxidative deamination to 3,4-dihydroxyphenylacetaldehyde (DOPAL), which is metabolized primarily to 3,4-dihydroxyphenylacetic acid (DOPAC) via aldehyde dehydrogenase, ALDH2. DOPAC exhibits the antiproliferative effect in colon cancer cells. In addition, DOPAC enhances not only the total ALDH activity but also the gene expression of ALDH1A1, ALDH2, and ALDH3A1 in a concentration-dependent manner. The pretreatment of DOPAC completely protects the cells from the acetaldehyde-induced cytotoxicity, thus DOPAC acts as a potential ALDH inducer to prevent the alcohol-induced abnormal reaction.
