Chlorogenic Acid: Characteristics, Neuroprotective Effects, and Potential Mechanisms

Area of Science:

• Neuroscience
• Pharmacology
• Nutritional Science

Background:

• Chlorogenic acid (CGA) is a natural polyphenol abundant in fruits and vegetables with recognized pharmacological activities.
• Emerging research suggests dietary CGA supplementation may offer neuroprotective benefits.
• Neuropsychiatric disorders represent a significant global health burden, necessitating novel therapeutic strategies.

Purpose of the Study:

• To review and synthesize current evidence linking CGA to neuropsychiatric disorders.
• To critically discuss the biological mechanisms underlying CGA's neuroprotective effects.
• To highlight the impact of CGA's chemical properties, sources, bioavailability, and pharmacology on its therapeutic potential.

Main Methods:

• Systematic review of animal studies investigating CGA's effects on various neuropsychiatric disorders.
• Analysis of CGA's chemical features, natural occurrence, and pharmacokinetic properties.
• Examination of molecular and cellular mechanisms, including neuroinflammation, oxidative stress, and protein aggregation.

Main Results:

• CGA demonstrates protective effects in animal models of Parkinson's disease, Alzheimer's disease, stroke, depression, and epilepsy.
• Neuroprotection is attributed to suppression of neuroinflammation, attenuation of oxidative stress, and modulation of synaptic/cellular homeostasis.
• CGA may influence autophagic activity and reduce the accumulation of misfolded proteins.

Conclusions:

• CGA exhibits significant potential as a therapeutic agent for neuropsychiatric disorders.
• Its neuroprotective mechanisms involve anti-inflammatory, antioxidant, and protein-homeostasis-regulating pathways.
• Further research is needed to establish a clear molecular framework for clinical application of CGA.
