Protocatechuic Acid Ameliorates Chronic Unpredictable Mild Stress Induced Depressive-Like Behavior in Mice

Vishnu N Thakare and Bhoomika M Patel

Statement of the Problem: Protocatechuic acid (PCA), a natural flavonoid elicited antidepressant-like activity in acute stress-induced depression. Amelioration of oxidative stress via promoting the endogenous antioxidant system and enhancement of monoamines in brain were the important underlying antidepressant mechanism of PCA.

Methodology & Theoretical Orientation: Depressive-like behaviors were induced by subjected mice to the CUMS protocol for 4 weeks. PCA was administered at doses of 100 and 200 mg/kg per oral and behavioral alterations (sucrose preference, immobility time, exploratory behavior) and biochemical changes mainly (serum corticosterone, monoamines, BDNF, inflammatory cytokines, TNF- α, IL-6, antioxidants parameters) in the hippocampus and cerebral cortex were investigated.

Findings: Experimental findings revealed that CUMS subjected mice induce significant impairment in behavioral alterations , mainly increased immobility time, impaired preference to the sucrose solution, monoamines, BDNF levels and serum corticosterone, cytokines, MDA formation with impaired antioxidants in the hippocampus and cerebral cortex.

Conclusion & Significance: Hence, the present findings demonstrated the antidepressant potential of PCA which is largely achieved probably through improving monoaminergic, BDNF and by modulation of the oxidative stress response, cytokines systems, and antioxidant defense system in mice.
