Members of the EAG family of voltage gated K+ channels are involved in several pathophysiological diseases and there has been a great interest in screening for drugs that modulate the activity of these channels. Many drugs have been shown to bind in the pore of these channels blocking ion flux and causing disease pathology. In this report we present two independent screening campaigns in which we wanted to identify small molecules that bind to either the intracellular cytoplasmic amino terminal PAS domain from the human ERG channel or bind to the amino or carboxy terminal globular domains from the mouse EAG1 channel affecting their interaction. We report that in both cases compounds were identified that showed weak, non-specific binding. We suggest alternative routes should be pursued in future efforts to identify specific, high affinity binders to these cytoplasmic domains.
