Novel openers of Ca2+-dependent large-conductance potassium channels: symmetrical pharmacophore and electrophysiological evaluation of bisphenols

Bioorg Med Chem Lett. 2003 Apr 17;13(8):1437-9. doi: 10.1016/s0960-894x(03)00156-2.

Abstract

Electrophysiological evaluation of symmetrical analogues of the known maxi-K opener NS-004 (1) led to the discovery of bisphenols 2a, 3a and 4a as openers of cloned maxi-K channels expressed in oocytes.
