Application

NS8593 hydrochloride has been used to study its effect on the growth of MDA-MB-231 cells (M.D. Anderson and metastasis breast cancer cells).[1]

Biochem/physiol Actions

NS8593 hydrochloride inhibits small conductance calcium-activated potassium (SKCa) channels.
The compound (R)-N-(benzimidazol-2-yl)-1,2,3,4-tetrahydro-1-naphtylamine (NS8593) reversibly inhibited recombinant SK3-mediated currents (human and rat SK3) with potencies around 100 nM. NS8593 did not inhibit 125I-apamin binding. NS8593 decreased the calcium sensitivity by shifting the activation curve for Ca2+ to the right, only slightly affecting the maximal Ca2+-activated SK current. NS8593 inhibited all the SK1-3 subtypes Ca2+-dependently (Kd = 0.42, 0.60, and 0.73 μM, respectively, at 0.5 μM Ca2+. NS8593 did not affect the calcium-activated potassium channels of intermediate and large conductance (hIK and hBK channels, respectively). NS8593-mediated inhibition was prevented in the presence of a high concentration of the positive modulator NS309.
