    CP 339818 hydrochloride

    		Potassium Channel Neurological Disease
    CP 339818 hydrochloride is a nonpeptide and selective Kv1.3 (IC50 value of ~200 nM) blocker. CP 339818 hydrochloride also inhibits Kv1.4 channels. CP 339818 hydrochloride is a significantly less potent blocker of Kv1.1, Kv1.2, Kv1.5, Kv1.6, Kv3.1-4, and Kv4.2. CP 339818 hydrochloride potently blocks the C-type inactivated conformation of Kv1.3 and suppresses T cell activation .

    5-(4-Phenoxybutoxy)psoralen

    		 Potassium Channel Inflammation/Immunology
    PAP-1 (5-(4-Phenoxybutoxy)psoralen) is a potent, selective, and orally active Kv1.3 blocker (EC50=2 nM). PAP-1 blocks Kv1.3 in a use-dependent manner and acts by preferentially binding to the C-type inactivated state of the channel. PAP-1 exhibits 23-fold selectivity over Kv1.5 (EC50=45 nM), and further displays 33- to 125-fold selectivity over all other Kv1-family channels. PAP-1 does not exhibit cytotoxic or phototoxic effects .

    Vm24-toxin

    Vaejovis mexicanus peptide 24

    		 Potassium Channel Inflammation/Immunology Cancer
    Vm24-toxin (Vaejovis mexicanus peptide 24), a 36-residue peptide, is a potent and selective Kv1.3 blocker with a Kd of ~3 pM in lymphocytes. Vm24-toxin shows >1500-fold affinity for Kv1.3 over other assayed potassium channels. Vm24-toxin folds into a distorted cystine-stabilized α/β motif consisting of a single-turn α-helix and a three-stranded antiparallel β-sheet, stabilized by four disulfide bridges. Vm24-toxin attenuates the CD4 + effector memory T cell response to T cell receptor (TCR) stimulation .

    CP-339818

    		Potassium Channel Neurological Disease
    CP-339818 is a non-peptide drug with potent Kv1.3 channel blocking activity. CP-339818 is able to effectively inhibit the activation of human T cells. By selectively blocking Kv1.3, CP-339818 is of great value in immune system research. The drug inhibits the C-type inactivated state of Kv1.3 channels in a use-dependent manner. CP-339818 has significantly weaker blocking effects on Kv1.1, Kv1.2, Kv1.5, Kv1.6, Kv3.1-4, and Kv4.2 channels, and only shows some inhibition on the Kv1.4 channel .
