Small molecule inhibitors of Abeta assembly.

Author information

Department of Molecular and Cellular Biochemistry, Chandler School of Medicine and the Center on Aging, University of Kentucky, KY, USA.


The Abeta peptide assembles into a variety of distinct types of structures in vitro and in the brain which have different biological consequences. Differential effects of inhibitory small molecules suggest that a sequential monomer - oligomer - fibril mechanism is overly simplistic and that soluble toxic oligomers and fibrils can be formed in common or separate pathways depending on the local environment. As a result, the effects of inhibitors are often assay-dependent because multiple pathways are operating. This review discusses strategies for teasing apart the intricate protein-protein interactions that result in Abeta assembly.
