Possible Interaction: Acetylcysteine and Dihydroxyphenylalanine

Research Papers that Mention the Interaction

Co‐infusion of N‐acetylcysteine (100 μm) or melatonin (50 μm) increased l‐DOPA (up to 151‐ and 246‐fold, respectively) and decreased l‐DOPA‐SQ (by about 53% and 87%, respectively) dialysate concentrations.

The decrease in cell viability by L‐DOPA (10±4% of control) or dopamine (15±4% of control) was markedly attenuated by antioxidants (ascorbic acid, glutathione, N‐acetyl‐L‐cysteine and sodium metabisulphite).

L‐DOPA auto‐oxidation is inhibited by NAC and enhanced by manganese.
intrastriatal infusion of N‐acetylcysteine (NAC) significantly increased DA and L‐DOPA dialysate concentrations and lowered those of L‐DOPA semiquinone; in addition, NAC decreased DOPAC+HVA and uric acid dialysate concentrations.

The antioxidant N‐acetyl‐L‐cysteine significantly inhibited decreases in cell viability, apoptosis, and changes in DA metabolism induced by the manganese association with L‐DOPA.
