Potassium channels (K-channels) selectively control the passive flow of potassium ions across biological membranes and thereby also regulate membrane excitability. Genetic variants affecting many of the human K-channels are well known causes of Mendelian disorders within cardiology, neurology, and endocrinology. K-channels are also primary targets of many natural toxins from poisonous organisms and drugs used within cardiology and metabolism.

The strategy of using small molecule inhibitors (SMIs) to fight strong (tight-binding) PPIs tends to fall short due to the flat and wide interfaces of PPIs. Here we propose a biligand approach for disruption of strong PPIs.
