Cat. No. 5571
Biological ActivityHigh affinity, selective KCa2.2 (SK2) channel blocker (Kd = 3.8 nM). Exhibits >200-fold selectivity for KCa2.2 over KCa2.1, KCa2.3, KCa3.1, IK, Kv and Kir2.1. Increases theta-burst responses and increases LTP in rat hippocampal slices in vitro. Convulsive in vivo.
(Modifications: X = Dab, Disulfide bridges: 3-21, 8-26, 12-28, His-31 = C-terminal amide)
