α‐M significantly decreased Aβ₄₀, Aβ₄₂ levels in primary cortical neurons. Aβ₄₀ (A), Aβ₄₂ (B), and sAPPα (C) levels were detected in supernatant from cultured cortical neurons incubated with various concentration of α‐M for 24 h. Data represent mean±SEM from at least three independent experiments performed in triplicate. *P<.05, **P<.01, compared with 0 nmol·L⁻¹ of α‐M
