MTT assay for SH-SY5Y cells viability: (a) viability detection of SH-SY5Y cells treated with H₂O₂ (25∼300 μmol·L⁻¹) for 2, 3, and 4 h. (b) Viability detection of SH-SY5Y cells treated with AS-IV (0.2∼5 μmol·L⁻¹) for 24 h (c) Viability detection of SH-SY5Y cells under H₂O₂ (50 μmol·L⁻¹) treatment for 3 h after AS-IV (0.1∼0.4 μmol·L⁻¹) pretreatment for 2 h.
