RESUMO

Objective: To investigate the effects of protocatechuic acid (PCA) on the midbrain dopaminergic neurons injured by 1-methyl-4-phenylpyridinium (MPP+). Methods: Midbrain neuron cells from KM mice pregnant 14 d were used in this experiment, and divided into control group, model group, low-, mid-, and high-dose (0.05, 0.1, and 0.5 mmol/L) groups. MTT method was used to determine the neuronal survival rate. The activity of lactate dehydrogenase (LDH) in culture, content of intracellular reactive oxygen species (ROS), activity of mitochondrial complex I, and mitochondrial membrane potential were further determined. Results: PCA can enhance the viability of dopaminergic neurons damaged by MPP+, reduce the release of LDH and the generation of ROS, increase the activity of the mitochondrial complex Ι, and prevent the reduction of mitochondrial membrane potential. Conclusion: PCA has the neroprotective effects against MPP+-induced damage of midbrain dopaminergic neurons.
