Spadin
Based on 1 publication(s) in Google Scholar
Spadin, a natural peptide derived from a propeptide released in blood, is a potent TREK-1 channel blocker with IC50 value of 10 nM. Spadin enhances dorsal raphe nucleus 5-HT neurotransmission in mice and induces hippocampal CREB activation and neurogenesis. Spadin can be used for antidepressant research.

Activité biologique
Spadin (100 nM; COS-7 cells) has inhibitory effect of spadin on the TREK-1 channel and blocks 63% of the TREK-1 current stimulated by arachidonic acid[1].
Spadin (100 nM) blocks the TREK-1 channels activity in CA3 hippocampal neurons on brain slices of wild-type mice[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Spadin (0.01-100 μM; ICV, i.p. and i.v.; daily, for 7 days; male C57Bl/6J and TREK-1 deficient mice) has anti-depressant behavior in mice[2].
