Abstract

Phencylidine (PCP) is a major drug of abuse in the United States. It produces a toxic confusional psychosis in man. We show here that nanomolar to micromolar concentrations of PCP and behaviorally active congeners selectively block voltage-regulated noninactivating (or very slowly inactivating) presynaptic K channels in the brain. The rank order of potency for blockage of these K channels parallels both the relative ability of these agents to produce characteristic behavioral deficits in rats and their ability to displace [3H]PCP from its high-affinity binding sites in brain. In view of the enhanced voltage-gated Ca influx that would be expected to accompany blockage of presynaptic K channels, this mechanism could explain the excessive neurotransmitter release that is characteristic of PCP intoxication.

摘要

苯环利定(PCP)是美国一种主要的滥用药物。它会在人类中引发中毒性混淆性精神病。我们在此表明,纳摩尔至微摩尔浓度的PCP及其具有行为活性的同系物能选择性地阻断大脑中电压调节性非失活(或非常缓慢失活)的突触前钾通道。这些钾通道阻断效力的顺序与这些药物在大鼠中产生特征性行为缺陷的相对能力以及它们从大脑中高亲和力结合位点置换[3H]PCP的能力均平行。鉴于预计突触前钾通道的阻断会伴随电压门控性钙内流增加,这种机制可以解释PCP中毒所特有的神经递质过度释放现象。
