Summary
Natural products offer promising neuroprotective potential for neurodegenerative diseases (NDs) by targeting multiple pathways. Further research and innovative delivery systems are needed to overcome limitations and enable clinical application.
Area of Science:
- Neuroscience
- Pharmacology
- Natural Product Chemistry
Background:
- Neurodegenerative diseases (NDs) like Alzheimer's and Parkinson's involve progressive neuronal loss, leading to significant disability and healthcare burdens.
- Current treatments offer symptomatic relief but do not halt disease progression, necessitating novel therapeutic strategies.
- Natural products are explored for their potential to modify disease mechanisms underlying NDs.
Purpose of the Study:
- To comprehensively review the therapeutic potential of natural products in targeting cellular and molecular mechanisms of NDs.
- To highlight the neuroprotective roles and disease-modifying capabilities of natural product-derived compounds.
- To identify key bioactive compounds and their mechanisms of action in preclinical and clinical studies.
Main Methods:
- A systematic literature review was performed using major scientific databases (PubMed, Scopus, Web of Science, Google Scholar).
- Analysis included peer-reviewed articles, clinical trials, and experimental studies focusing on natural products and NDs.
- Evaluated therapeutic potential and mechanisms of action of natural products and their bioactive constituents.
Main Results:
- ND pathogenesis involves oxidative stress, neuroinflammation, mitochondrial dysfunction, and protein aggregation.
- Natural products, including flavonoids, alkaloids, and polyphenols, exhibit potent antioxidant, anti-inflammatory, and neuroprotective effects.
- Key compounds like curcumin and resveratrol modulate critical signaling pathways, reduce protein aggregation, and protect neurons in studies.
Conclusions:
- Natural products show promise for disease modification in NDs due to multi-target actions and lower toxicity.
- Challenges such as poor bioavailability and pharmacokinetic variability impede clinical translation.
- Advanced drug delivery systems and synergistic formulations are crucial for overcoming limitations and advancing clinical application.

Drugs Affecting Neurotransmitter Synthesis
Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase, which converts...
Parkinson's Disease: Overview
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is to...
Alzheimer's Disease: Treatment
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
Alzheimer's Disease: Overview
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ and tau...

Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
Neurochemical Transmission: Sites of Drug Action
Neurochemical transmission, the conduction of electrical impulses between neurons mediated by neurotransmitters, plays a vital role in various physiological processes. Autonomic drugs exert their effects by modulating neurotransmission within the autonomic nervous system. For instance, drugs such as hemicholinium block the precursor uptake necessary for synthesizing acetylcholine, an essential autonomic neurotransmitter. Following synthesis, neurotransmitters are stored in vesicles. Metyrosine...
