High 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
Lei-Dab7 TFA, a selective and high-affinity blocker of the K Ca 2.2 (SK2) channel with a dissociation constant (K d) of 3.8 nM, demonstrates over 200-fold selectivity for K Ca 2.2 compared to K Ca 2.1, K Ca 2.3, K Ca 3.1, K v, and Kir2.1. Furthermore, Lei-Dab7 TFA enhances theta-burst responses and long-term potentiation (LTP) in rat hippocampal slices in vitro.
