Tertiapin (TPN), a potent inhibitor of the inward-rectifier K⁺ channels, blocked a G-protein-gated channel (GIRK1/4) and the ROMK1 channel with nanomolar affinities, however a closely related channel, IRK1, was insensitive to tertiapin. Thus, tertiapin will be a powerful ligand for purifying functional channels as well as for screening pharmaceutical agents against these channels.
