Description: UCL2077 is a selective slow-afterhyperpolarization (sAHP) channel blocker. UCL2077 suppresses the sAHP present in hippocampal neurons in culture and in the slice preparation. UCL2077 is selective and has minimal effects on Ca(2+) channels, action potentials, input resistance and the medium afterhyperpolarization.
