Inhibition of Acyl-CoA: Cholesterol Acyltransferase (ACAT), Overexpression of Cholesterol Transporter Gene, and Protection of Amyloid β (Aβ) Oligomers-Induced Neuronal Cell Death by Tricyclic Pyrone Molecules
摘要:
A major effort in Alzheimer's disease therapeutic development has targeted A beta and downstream :vents. We have synthesized a small library of tricyclic pyrone compounds. Their protective action in MC65 cells and inhibition of ACAT along with the upregulation of cholesterol transporter gene were investigated. Five active compounds exhibited potencies in the nanomolar ranges. The multiple effects of the compounds on A beta and cellular cholesterol pathways could be potential mechanisms underlying the protective effects in vivo.
