    • The invention relates to a method for identifying the agonistic activity of a target compound on a potassium channel, characterized in that: a) a population of cells is prepared, which express a potassium channel and optionally a protein-based fluorescent-optical strain sensor, b) optionally the cells are incubated according to a) with a strain-sensitive fluorescent dye, c) the target compound is added to the reaction mixture of a) or b), d) a value F 1 is determined for the fluorescence intensity of the cells, d) potassium ions are added in a physiologically tolerable concentration, f) a value F 2 is determined for the fluorescence intensity of the cells, and g) the fluorescence intensity F 2 is compared with the fluorescence intensity F 1, and the agonistic activity of the target compound on the potassium channel is determined therefrom. The invention also relates to a purified potassium channel agonist isolated with this method, medications containing said agonist, and the use thereof for treatment of a disease in which potassium channels are involved.
