Cat. No. 2661
Chemical Name: N-Trityl-3-pyridinemethanamine
Biological ActivitySlow afterhyperpolarization (sAHP) channel blocker; reduces sAHP in hippocampal slice preparations. Displays no effect on Ca2+ currents or the time course of sAHP/sIAHP. Exhibits potent inhibition of KCNQ1 and KCNQ2, but differential effects at other KCNQs. Rescues memory retrieval in dopamine β-hydroxylase knockout mice.
