来自人脑的淀粉样前体蛋白 (APP) β-分泌酶在淀粉样蛋白 β-蛋白 (Aβ) 序列的氨基末端裂解全长 APP，从而导致 β-裂解的可溶性 APP 和相应细胞的产生和细胞外释放,-相关的羧基末端片段。随后由γ-分泌酶切割C-末端片段导致形成Aβ。这种新肽是一种有效的 APP β-分泌酶底物类似物抑制剂，IC₅₀ = 30 nM。

Amyloid precursor protein (APP) β-secretase from human brain cleaves full-length APP at the amino terminus of the amyloid β-protein (Aβ) sequence, thus leading to the generation and extracellular release of β-cleaved soluble APP and a corresponding cell-associated carboxy-terminal fragment. The subsequent cleavage of the C-terminal fragment by γ-secretase(s) leads to the formation of Aβ. This new peptide represents a potent substrate analog inhibitor of APP β-secretase with IC₅₀ = 30 nM.
