MPiN
MPiN is a KV1.3 potassium channel inhibitor. The IC50 values of MPiN for inhibiting Kv1.3 currents are 1.1 μM (at -90 mV) and 0.6 μM (at -35 mV). MPiN exhibits in vivo efficacy in a mouse psoriasis model. MPiN can be used for the research of psoriasis.

In Vitro
MPiN (10 μM) potently and reversibly inhibits human KV1.3 channels expressed in HEK293T cells, with higher inhibitory potency for inactivated channels (IC50 = 0.6 μM) than for closed channels (IC50 = 1.1 μM)[1].
MPiN (10 μM; 5 min) selectively inhibits human KV1.3 channels expressed in HEK293T cells, and acts only after the channels open[1].
MPiN (5-20 μM) allosterically promotes voltage sensor activation of human KV1.3 channels expressed in HEK293T cells, while inhibiting channel currents and inducing a hyperpolarizing shift in the activation curve without altering steady-state inactivation[1].
MPiN binds to a novel extracellular pocket formed by the PP1-PP2 turret loop, pore helix, and outer S5/S6 helices on human KV1.3[1].
