Natural Cinnamaldehyde and Its Derivatives Ameliorate Neuroinflammatory Pathways in Neurodegenerative Diseases

الملخص EN

Neurodegenerative diseases are devastating and incurable disorders characterized by neuronal dysfunction.

The major focus of experimental and clinical studies are conducted on the effects of natural products and their active components on neurodegenerative diseases.

This review will discuss an herbal constituent known as cinnamaldehyde (CA) with the neuroprotective potential to treat neurodegenerative disorders, such as Alzheimer’s disease (AD) and Parkinson’s disease (PD).

Accumulating evidence supports the notion that CA displays neuroprotective effects in AD and PD animal models by modulating neuroinflammation, suppressing oxidative stress, and improving the synaptic connection.

CA exerts these effects through its action on multiple signaling pathways, including TLR4/NF-κB, NLRP3, ERK1/2-MEK, NO, and Nrf2 pathways.

To summarize, CA and its derivatives have been shown to improve pathological changes in AD and PD animal models, which may provide a new therapeutic option for neurodegenerative interventions.

To this end, further experimental and clinical studies are required to prove the neuroprotective effects of CA and its derivatives.
