Neurodegenerative diseases are a group of life-threatening conditions characterized by gradual and severe neuronal degeneration, posing a significant global health challenge. Many neurodegenerative diseases, including Alzheimer's disease and Parkinson’s disease, share identical and recognizable etiologies, such as neuronal degeneration, apoptosis, oxidative stress, lipid peroxidation, Ca2+ overload, neuroinflammation, protein aggregation, endoplasmic reticulum stress, and mitochondrial dysfunction. Among these etiologies, oxidative stress and mitochondrial dysfunction are the primary contributing factors, involving several enzymes and signaling molecules in the underlying mechanism of disease progression. Globally available treatments provide only temporary symptomatic relief with side effects, and yet there is no medication to eradicate the disease-related cause.
Extensive research has explored novel herbal medications offered as neuroprotective against these debilitating conditions, aiming to reverse or halt the disease progression with minimal adverse effects. Pinostrobin is a major bioactive flavonoid primarily isolated from Boesenbergia rotunda (Fingerroot). Established research has reported that pinostrobin exhibits a wide array of pharmacological activities, including anti-inflammatory, anti-leukemia, antioxidant, antimicrobial properties, as well as protective effects against mitochondrial dysfunction and neurodegeneration.
Based on preclinical studies, we have summarised the current knowledge of pinostrobin's neuroprotective actions, highlighting its effectiveness in mitigating neuronal damage, preserving synaptic function, reducing oxidative stress, neuroinflammation, protein aggregation, mitochondrial apoptosis, and calcium overload. These mechanisms collectively support its therapeutic potential in modulating the molecular pathways underlying Alzheimer’s and Parkinson’s disease.
This review offers a comprehensive analysis of pinostrobin and its molecular pathways in combating neurodegenerative diseases, highlighting its promising effectiveness as a natural neuroprotective agent in Alzheimer’s and Parkinson’s disease by modulating mitochondrial and oxidative stress-mediated pathways.
