human beta-amyloid protein 42

Human beta-amyloid protein 42 (1-7) is a bioactive chemical.

hAChE-IN-6 (compound 51) is a brain-penetrant acetylcholinesterase (AChE) inhibitor with an IC50 of 0.16 μM. It also inhibits human butyrylcholinesterase (hBuChE) and glycogen synthase kinase 3 beta (GSK3β), with IC50 values of 0.69 μM and 0.26 μM, respectively. Additionally, hAChE-IN-6 impedes the self-aggregation of tau protein and amyloid-beta 1-42 (Aβ1-42), making it useful for Alzheimer's disease (AD) research [1].

hAChE-IN-5 (compound 49) is a dual inhibitor of human acetylcholinesterase (hAChE) and human butyrylcholinesterase (hBuChE), showing IC50 values of 0.17 μM for both enzymes. It also potently inhibits glycogen synthase kinase 3 beta (GSK3β) with an IC50 of 0.21 μM. Furthermore, it effectively inhibits tau protein and Aβ1-42 peptide self-aggregation, and can bind the peripheral anionic site (PAS) to prevent amyloid-beta (Aβ)-induced neurotoxicity. hAChE-IN-5's ability to cross the blood-brain barrier (BBB) supports its potential in developing multitargeted anti-Alzheimer's agents [1].
