Targeting the Parkinson's disease using sim (Rhodomyrtus tomentosa) fruit water extract.

Area of Science:

• Neuroscience
• Pharmacology
• Biochemistry

Background:

• Parkinson's disease (PD) is a neurodegenerative disorder characterized by dopaminergic neuron loss, leading to motor deficits and reduced quality of life.
• Current PD therapies offer symptomatic relief but lack disease-modifying effects; novel treatments targeting underlying mechanisms like oxidative stress are needed.
• Natural compounds with antioxidant properties are being explored as potential therapeutic agents for PD, offering a safer alternative to long-term synthetic drug use.

Purpose of the Study:

• To investigate the therapeutic potential of Sim fruit water extract (SFWE) for Parkinson's disease (PD).
• To evaluate the antioxidant capacity of SFWE and its effects on dopaminergic neuron degeneration and locomotor dysfunction in a PD Drosophila model.

Main Methods:

• Utilized a Drosophila melanogaster model with knockdown of dUCH to mimic PD symptoms, including dopaminergic neuron degeneration and locomotor impairment.
• Assessed the antioxidant capacity of SFWE using IC50 value determination.
• Administered SFWE to the PD fly model to evaluate its effects on reactive oxygen species (ROS) levels, dopaminergic neuron survival, and motor function.

Main Results:

• SFWE exhibited significant antioxidant capacity with an IC50 value of 55.55 ± 2.012 µg/mL.
• SFWE treatment (1.25 mg/mL) effectively reduced ROS levels in dopaminergic neurons of the PD fly model.
• SFWE ameliorated dopaminergic neuron degeneration and rescued locomotor deficits in the PD Drosophila model.
• SFWE did not adversely affect fruit fly development or lifespan, indicating a favorable safety profile.

Conclusions:

• Sim fruit water extract possesses potent antioxidant properties and demonstrates neuroprotective effects against oxidative stress-induced neurodegeneration.
• SFWE effectively alleviates hallmark symptoms of Parkinson's disease, including dopaminergic neuron loss and motor dysfunction, in a relevant animal model.
• Sim fruit represents a promising natural source for developing novel, safe, and effective therapeutic strategies for Parkinson's disease.
