CP 339818 hydrochloride is a non-peptide blocker of Kv1.3 (IC50 = 200 nM) and Kv1.4 channels. It also inhibits HCN channels with IC50s of 18.9 μM and 43.4 μM against HCN1 and HCN4 (high Cl-), respectively. The compound exhibits significantly weaker blocking effects on Kv1.1, Kv1.2, Kv1.5, Kv1.6, Kv3.1-4, and Kv4.2 channels. It selectively blocks Kv1.3, which in turn inhibits the activation process of human T cells. CP 339818 hydrochloride can be utilized for studying the physiological functions of HCN and Kv channels. For research use only, not for sale to patients.
