MK-3328 has a high affinity for β-Amyloid (IC50:10.5 nM), and can be used as a candidate PET ligand for clinical assessment of β-amyloid plaque load. MK-3328 is a potential treatment for Alzheimer's disease.

β-Amyloid (11-22) is a peptide fragment of β-Amyloid.Beta-amyloid peptide (Abeta), the major constituent of amyloid plaques in the brains of Alzheimer’s patients, is thought to be the cause of Alzheimer’s Disease (AD). AD is the most common neurodegenerative disease and afflicts about 10% of the population over 60.

Amyloid β-Protein (10-20) is a fragment of Amyloid-β peptide, maybe used in the research of neurological disease.Amyloid β protein fragment containing the α-secretase processing site (Lys16-Leu17 bond). It also contains the HHQK domain (residues 13-16) responsible for binding to microglial cells.
