    Scientific background

    The benzothiazinone NS-6180 is a potent and selective KCa3.1 channel blocker1.

    The Ca2+-activated K+ channel, KCa3.1, plays a major role in the controlled expression of essential genes orchestrating proliferation, migration and cytokine production by participating in the regulation of calcium entry. A highly regulated and sustained increase in cytosolic Ca2+ is critical in these processes thus, the KCa3.1 channel is a potential target for therapy of immune disease1.

    Inhibition of KCa3.1 channel by NS-6180 demonstrates IC50 value of 14 nM in human, 9 nM in rat and 15 nM in mouse. NS6180 also has the ability to inhibit KCa1.1, KV1.3 and KV11.1 channels with IC50s above 10 µM2.
