1.D.54 The potassium-selective Hexyl-Benzoureido-15-Crown-5-Ether Channel (HBEC) Family

Artificial ion-channels of H-bonded hexyl-benzoureido-15-crown-5-ether are selective for K+ over Na+. K+-channel conductance arises from the formation of oligomeric cooperative channels, resulting in cation-induced membrane polarization and enhanced transport rates. These channels are selectively responsive to the presence of K+ cations, even in the presence of a large excess of Na+ (Gilles and Barboiu 2015).
