β-Amyloid (1-42) (Amyloid β-peptide (1-42), human TFA, a 42-amino acid peptide that has not been treated with HFIP, is a brain-penetrant amyloid protein fragment, which can be used in research on Alzheimer's disease and Down’s syndrome. β-Amyloid (1-42), human TFA remaining as a monomer exhibits antioxidant and neuroprotective effects. β-Amyloid (1-42), human TFA, after being monomericized by HFIP and dissolved in DMSO to form the stock solution, on the one hand, can form soluble oligomers (AβOs) when incubated at 4 °C, which have synaptic toxicity and neurotoxicity; on the other hand, it can be incubated at 37 °C to form insoluble fibrils, with lower neurotoxicity, and participating in the oxidative damage process. Aβ42 oligomers bind to various neuronal surface receptors (such as PrPc, mGluR5, NMDA receptors, etc.), triggering oxidative stress, calcium homeostasis imbalance, and synaptic toxicity via activating downstream signaling pathways, leading to neuronal dysfunction and death .

Aleplastinin (PAZ-417) is an orally active, blood-brain barrier permeable, selective SERPINE1 (PAI-1) inhibitor (IC50=655 nM). Aleplastinin activates the tissue type plasminogen activator (tPA)/fibrinolysis cascade by inhibiting PAI-1, thereby promoting the degradation of amyloid-β (Aβ) oligomers and monomers. Aleplastinin can significantly reduce plasma and brain Aβ levels, improve memory impairment, and reverse cognitive impairment. Aleplastinin can be used for research on Alzheimer's disease .

BD-Oligo is an oligomer-specific fluorescent chemical probe. BD-Oligo preferentially identifies Aβ oligomer assemblies over monomers or fibrils by using diversity-directed fluorescent library (DOFL) screening and computational techniques. BD-Oligo exhibits dynamic oligomer monitoring capabilities during Aβ peptide fibril formation as Aβ is induced to form oligomers and ultimately fibrils over time. BD-Oligo also exhibits blood-brain barrier permeability with the ability to stain Aβ oligomers in vivo .

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 .
