Tacrine was 8 times more potent than HupA in inhibition of 〓(〓=115μM) and 20 times more potent than HupA in inhibition of 〓(〓=43. 2μM). Tacrine at 10 mM could completely block the two currents.

他可林对〓的阻断作用（〓=115μM）比石杉碱甲强8倍，对〓的阻断作用（〓=43.2 μM）比石杉碱甲强20倍，10mM他可林能够完全阻断两种钾电流。

The inhibition on these channels by HupA and Tacrine might form a potential toxic effect in the treatment of AD, because their 〓 values in inhibition of Cholinesterase are only 0.082 μM and 0.090 μM respectively.

石杉碱甲对电压门控钾通道的作用，与其胆碱酯酶抑制活性相比较（〓=0.082μM），相差近一万倍，因此不可能对AD的治疗有直接的联系，相反，它可能成为潜在的副作用。
