(Pyr3)-Amyloid β-Protein (3-42) TFA is an N-terminally truncated pyroglutamylated β-amyloid peptide. (Pyr3)-Amyloid β-Protein (3-42) TFA forms stable β-sheet structures across different pH values, co-oligomerizes with Aβ1-42 to form cytotoxic oligomers, induces tau-dependent cytotoxicity and neuronal loss, inhibits hippocampal LTP, and exhibits stronger protease resistance. (Pyr3)-Amyloid β-Protein (3-42) TFA exists in the brain tissues of human Alzheimer's disease patients, correlates with the pathogenesis of Alzheimer's disease, and follows a unique, faster oligomerization pathway. (Pyr3)-Amyloid β-Protein (3-42) TFA can be used in Alzheimer's disease-related research .

Withanoside V is a blood-brain barrier-permeable withanolide derivative . Withanoside V binds strongly to Sudlow I (domain IIA) of human serum albumin (HSA) to form a stable complex and alter the secondary structure of albumin, thereby increasing helix content and reducing β-sheet and random coil. Withanoside V binds to Aβ (1-42) to block the interaction between monomers and subsequent aggregation. Withanoside V inhibits the viability of neuroblastoma cells, reduces the number of apoptotic cells induced by Aβ (1-42), and decreases ROS production. Withanoside V inhibits SARS-CoV-2 Mpro. Withanoside V can be used for research on Alzheimer's disease and coronavirus disease 2019 .

Amyloid-Forming peptide GNNQQNY is a biological active peptide. (This is a heptapeptide from the N-terminal prion-determining domain of the yeast protein Sup35 that forms amyloid fibrils. The availability of its detailed atomic oligomeric structure makes it a good model for studying the early stage of aggregation. The GNNQQNY dimer forms three stable sheet structures. in-register parallel, off-register parallel, and anti-parallel. The in-register parallel dimer, which is close to the amyloid beta-sheet structure, has few interpeptide hydrogen bonds, making hydrophobic interactions more important and increasing the conformational entropy compared to the anti-parallel sheet.)
