Flavonoids Alleviate Peripheral Neuropathy Induced by Anticancer Drugs

Area of Science:

• Neuroscience
• Pharmacology
• Biochemistry

Background:

• Chemotherapy-induced peripheral neuropathy (CIPN) is a common and debilitating side effect of cancer treatment.
• Current treatments for CIPN have limited efficacy and significant side effects.

Purpose of the Study:

• To evaluate the potential of flavonoids as a therapeutic strategy for CIPN.
• To review the mechanisms by which flavonoids may combat CIPN.

Main Methods:

• A systematic literature search was conducted using PubMed and Google Scholar.
• Studies focusing on flavonoids in CIPN models and related neuropathic pain models, specifically targeting peripheral mechanisms, were included.

Main Results:

• Flavonoids were found to inhibit key CIPN mechanisms including proinflammatory cytokine release, glial activation, oxidative stress, neuronal apoptosis, and ion channel dysfunction.
• Flavonoids demonstrated efficacy in reducing CIPN symptoms such as thermal hyperalgesia and mechanical, tactile, and cold allodynia.

Conclusions:

• Flavonoids represent a promising therapeutic avenue for managing CIPN.
• Further research is essential to elucidate the precise pharmacological actions and potential side effects of flavonoids in human models before clinical application.
