Description: Selective negative modulator of KCa2 (SK) channels; inhibits SK currents
Chemical Name: N-[(1R)-1,2,3,4-Tetrahydro-1-naphthalenyl]-1H-benzimidazol-2-amine hydrochloride
Purity: ≥98% (HPLC)
Biological Activity for NS 8593 hydrochloride
NS 8593 hydrochloride is a selective KCa2 (SK) channel negative modulator; inhibits SK channel currents (Kd values are 0.42, 0.6 and 0.73 μM for SK1, SK2 and SK3 respectively at 0.5 μM Ca2+). Exhibits selectivity for SK channels over KCa1.1 (BK), KCa3.1 (IK), Kv, Nav and Cav channels. Inhibits afterhyperpolarization in hippocampal slices.

NS 8593 worked great on experimental conditions.
By
Sadequl Islam on 10/13/2018
Assay Type: In Vivo
Species: Mouse
Product was used to study SK channel activity. Shows channel blocking activity and reduced Calcium activated opening. Great product, performs well and stable.
The product was dissolved in DMSO. Sterile DMSO must be used for sterile cell culture studies.
