Background:

ADWX 1 is a potent and selective inhibitor of KV1.3 channel with IC50 values of 1.89 pM and 0.65 nM for Kv1.3 and Kv1.1, respectively [1].

Potassium voltage-gated channel (KV1.3 channel) is a potassium channel and plays an important role in regulating Ca2+ signaling and the resting membrane potential. KV1.3 is an attractive target for immunomodulation of T cell-mediated autoimmune diseases [1].

ADWX 1 is a potent and selective KV1.3 channel inhibitor. In the transiently transfected HEK293 cells, ADWX-1 inhibited potassium channel with IC50 values of 1.89 pM and 0.65 nM for Kv1.3 and Kv1.1, respectively [1].

In a rat experimental autoimmune encephalomyelitis (EAE) model, ADWX-1 lowered the clinical scores and significantly reduced inflammatory infiltrates. Also, ADWX-1 reduced the levels of IL-2 and IFN-γ. In MBP-stimulated PBMCs from ADWX-1-treated EAE rats, IL-2 secretion was decreased significantly. In the EAE model, the CD4+CCR7- TEM cells were inhibited by ADWX-1. Also, ADWX-1 inhibited IL-2 secretion by CD4+CCR7- TEM cells through the NF-B- and NF-AT-dependent way [2].
