The protective effect of natural compounds against rotenone-induced neurotoxicity

Area of Science:

• Neuroscience
• Toxicology
• Pharmacology

Background:

• Rotenone, a common organic pesticide, induces neurotoxicity by inhibiting mitochondrial complex I.
• Key cellular outcomes of rotenone toxicity include oxidative stress, apoptosis, and reduced autophagy.
• Understanding rotenone's neurotoxic mechanisms is crucial for developing protective strategies.

Purpose of the Study:

• To review natural compounds (NCs) with protective effects against rotenone-induced neurotoxicity.
• To explore the potential of NCs in mitigating rotenone's adverse cellular effects.

Main Methods:

• Literature review of in vitro and in vivo studies.
• Analysis of natural compounds demonstrating protective properties against rotenone.
• Focus on compounds exhibiting antioxidant, anti-apoptotic, and autophagy-enhancing activities.

Main Results:

• Several natural compounds have demonstrated significant protective effects against rotenone neurotoxicity.
• These NCs counteract rotenone's effects by reducing oxidative stress and apoptosis.
• The reviewed NCs also enhance autophagy, a key cellular process impaired by rotenone.

Conclusions:

• Natural compounds represent a promising therapeutic avenue for rotenone neurotoxicity.
• Targeting mitochondrial complex I inhibition and its downstream effects is a viable strategy.
• Further research into specific NCs could lead to novel neuroprotective agents.
