Application

UCL 2077 has been used for slow afterhyperpolarization (sAHP) studies in thalamic paraventricular nucleus (PVT) neurons. UCL 2077 has also been used for studying its effects on the increase in excitability of hippocampal pyramidal cells.

Biochem/physiol Actions

UCL 2077 is a slow afterhyperpolarization (sAHP) channel blocker.

Preparation Note

UCL 2077 is soluble in DMSO at a concentration >20 mg/ml and is insoluble in water.

The slow afterhyperpolarization (sAHP) in hippocampal neurons has been implicated in learning and memory. However, its precise role in cell excitability and central nervous system function has not been explicitly tested for 2 reasons: 1) there are, at present, no

Thalamic paraventricular nucleus (PVT) neurons exhibit a postburst apamin-resistant slow afterhyperpolarization (sAHP) that is unique to midline thalamus, displays activity dependence, and is abolished in tetrodotoxin. Analysis of the underlying sI(AHP) confirmed a requirement for Ca(2+) influx with contributions from
