Natural compounds represent a rich source of neuroprotective agents that have been used traditionally and are now being validated through modern scientific research. These compounds often target multiple pathways involved in neurodegeneration, offering potential advantages over single-target drugs.
Source: Curuma longa (turmeric root)
Mechanisms:
- Anti-inflammatory: Inhibits NF-κB, COX-2, iNOS
- Antioxidant: Scavenges ROS, upregulates Nrf2
- Anti-amyloid: Inhibits Aβ aggregation, promotes clearance
- Anti-tau: Reduces tau phosphorylation
Clinical Evidence:
- Multiple Phase I/II trials for AD showing safety and some cognitive benefit
- Bioavailability challenges addressed with nanoparticle formulations
- Synergistic effects with other natural compounds
