fibrils

(-)-Epigallocatechin, the predominant flavonoid in green tea, possesses the unique ability to attach to unfolded native polypeptides, thereby inhibiting their transformation into amyloid fibrils.

Crocin-4, a carotenoid compound found in saffron, possesses potent antioxidant properties and can penetrate the brain. It effectively inhibits the aggregation and deposition of Aβ fibrils, making it useful for Alzheimer's Disease research. Additionally, Crocin-4 demonstrates antitumor and anti-inflammatory activities.
