Mitochondrial Therapeutics
Overview
Mermaid diagram (expand to render)
<table class="infobox infobox-therapeutic">
Mitochondrial therapeutics encompass a diverse set of approaches targeting mitochondrial dysfunction, a central hallmark of neurodegeneration. Mitochondrial defects—including impaired oxidative phosphorylation (OXPHOS), increased [reactive oxygen species](/entities/reactive-oxygen-species) (ROS), defective mitophagy, and mitochondrial DNA mutations—are implicated in Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and other neurodegenerative conditions. This page covers pharmacological agents, gene therapies, and emerging strategies for restoring mitochondrial health. [@shults2002]
Mechanism of Action
Mitochondrial Dysfunction in Neurodegeneration
Parkinson's Disease
Complex I deficiency in substantia nigra dopaminergic [neurons](/entities/neurons)
PINK1 and PARKIN mutations causing mitophagy defects
[Alpha-synuclein](/proteins/alpha-synuclein) aggregation impairing mitochondrial function
Alzheimer's Disease
[Amyloid-beta](/proteins/amyloid-beta) and [tau](/proteins/tau) localization to mitochondria
Implemented cytochrome c oxidase (Complex IV) activity
Mitochondrial DNA mutations accumulating with age
Amyotrophic Lateral Sclerosis
SOD1 and [C9orf72](/entities/c9orf72) mutations affecting mitochondrial dynamics
Defective calcium buffering
Energy failure in motor neurons
Therapeutic Strategies
Key Therapeutic Agents
Coenzyme Q10 (CoQ10)
Mechanism : Electron carrier in ETC; antioxidantDose : 100-300 mg/day (often divided)Status : Clinical trials for PD, AD, and Huntington's diseaseEvidence : Mixed; some benefit in early PD (QE3 trial)Idebenone
Mechanism : CoQ10 analog; antioxidantDose : 90-270 mg/dayStatus : Approved in Europe for Friedreich's ataxiaTrials : AD and PD trials completedMitoQ (Mitoquinone)
Mechanism : CoQ10 conjugated to lipophilic cation for mitochondrial targetingDose : 10-40 mg/dayStatus : Available as supplementTrials : Ongoing for PD and agingSS-31 (Bendavia/Elamipretide)
Mechanism : Cardiolipin protector; enhances ETC couplingDose : 40 mg/day (subcutaneous)Status : Clinical trials for mitochondrial myopathies; AD trials plannedEvidence : Promising in preclinical modelsUrolithin A
Mechanism : Mitophagy inducer via PINK1 pathwayDose : 500-1000 mg/dayStatus : Dietary supplement; clinical trialsEvidence : Improves mitochondrial function in humansMdivi-1
Mechanism : [Drp1](/proteins/drp1-protein) inhibitor; blocks excessive fissionStatus : Preclinical; not yet in human trialsClinical Evidence
