Chemical Structure
CP-339818
- CAS No.: 185855-91-8
- Formula:C21H24N2
- Molecular Weight:304.43
IUPAC Name: (Z)-1-benzyl-N-pentylquinolin-4(1H)-imine
InChIKey: MMGAVKCAGQCFHS-XDOYNYLZSA-N
SMILES: CCCCC/N=C1C=CN(CC2=CC=CC=C2)C3=C/1C=CC=C3
Biological Activity: CP-339818 is a non-peptide Kv1.3 channel (IC50 = 200 nM) and Kv1.4 channel blocker. CP 339818 inhibits HCN channel with IC50s of 18.9 μM and 43.4 μM against HCN1 and HCN4 (high Cl-). CP-339818 has significantly weaker blocking effects on Kv1.1, Kv1.2, Kv1.5, Kv1.6, Kv3.1-4, and Kv4.2 channels. CP-339818 selectively blocked Kv1.3, thereby inhibiting the activation process of human T cells. CP-339818 can be used to study the physiological functions of HCN and Kv channels[1][2][3].
