PhiKan 083 is a small molecule primarily used in research focused on neurodegenerative diseases, particularly Alzheimer's disease, involving protein misfolding and aggregation of the tau protein. It functions as a pharmacological chaperone to stabilize tau structures and inhibit the formation of neurofibrillary tangles. The compound is utilized in biochemical assays, cellular models, and preclinical studies to explore its effects on protein interactions and aggregation pathways. Its application extends to drug discovery as a tool compound for investigating therapeutic strategies to modulate protein behavior in disease contexts.
