Antiamyloidogenic Chemical/Biochemical-Based Designed Nanoparticle as Artificial Chaperone for Efficient Inhibition...

Protein aggregation is linked to variety of neurodegenerative disorders and other diseases. Current research involves understanding the mechanism of protein aggregation, inhibiting protein aggregation under intra/extracellular space, lowering toxicity arising due to soluble oligomers, and augmenting the clearance of protein aggregates from the brain. Toward this direction, different types of antiamyloidogenic small molecules, macromolecules, and nanomaterials are identified that can inhibit protein aggregation, and extensive progress has been made for their effective utilization. Here, we summarize our effort in designing a nanoparticle form of antiamyloidogenic molecules with enhanced performance under in vitro and in vivo conditions. We found that the nanoparticle form of antiamyloidogenic molecules can perform up to 100,000-times better than the respective molecular form due to the combined effect of enhanced bioavailability at intra/extracellular space and multivalent binding property with aggregating protein. This work demonstrates that further research should be directed toward designing nanoparticle forms of antiamyloidogenic molecules for their effective performance.
