简介内容:PD-85639 is a voltage-gated sodium (Na+) channel blocker (75% in 10 min & >95% in 25 min blockage of Na+ current by 25 μM PD85,639; whole-cell patch clamp using primary rat brain neurons) that is shown to target rat brain with simultaneous high- and low-affinity modes of binding (EC50 = 56 nM/40% & 20 μM/60% at pH , 5 nM/28% & 3 μM/72% at pH , against 2 nM [3H]-PD85,639 for binding rat brain synaptosomes; EC50 = 17 nM/39% & 10 μM/61% using at pH using rat brain synaptosome membr
