CP-339818

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 531744

CAS#: 185855-91-8

Description: CP-339818 blocks both Kv1.3 and Kv1.4. CP-339818 is valuable for immune system studies, where the absence of Kv1.4 makes it functionally selective for Kv1.3, and it has shown suppression of T cell activation. Kv1.3 is expressed in the brain and in effector memory Tem (T) cells, and it is a member of the Shaker family of voltage-gated potassium channels.
