KYL acetate(676657-00-4 free base) 是EphA4受体酪氨酸激酶抑制剂（Kd = 0.8 μM）；抑制 EphA4-EphrinA5 相互作用 (IC50 = 6.34 μM)。防止 AβO 诱导的突触损伤、树突棘丢失并防止海马 CA3-CA1 传输中 LTP 的阻断。在细胞培养基中表现出较长的半衰期（在 PC3 和 C2C12 培养基中分别为 8 和 12 小时）。它有神经保护作用。

EphA4 receptor tyrosine kinase inhibitor (Kd = 0.8 μM); inhibits EphA4-EphrinA5 interactions (IC50 = 6.34 μM). Prevents AβO induced synaptic damage, dendritic spine loss and prevents the blocking of LTP in hippocampal CA3-CA1 transmissions. Exhibits a long half life in cell culture media (8 and 12 hours in PC3 and C2C12 media respectively). Neuroprotective.
