Application
Tertiapin was used for developing a novel CZE-DAD method for analyzing the honeybee venom.
Biochem/physiol Actions
A potent inhibitor of the inward-rectifier K+ channels, blocked a G-protein-gated channel (GIRK1/4) and the ROMK1 channel with nanomolar affinities, however a closely related channel, IRK1, was insensitive to tertiapin. Thus, tertiapin is a tool for purifying functional channels as well as for screening pharmaceutical agents against these channels.
Potent inhibitor of the inward-rectifier K+ channels.
Tertiapin is a peptide isolated from honey bee venom, which is a selective IKACh blocker that prolongs the atrial effective refractory period and terminates the atrial fibrillation. It is a selective and potent inhibitor of muscarinic K+ channels in rabbit cardiac myocytes.
Preparation Note
Tertiapin dissolves in water at 1 mg/ml to yield a clear solution.

Tertiapin is a 21-residue peptide isolated from honey bee venoms. A recent study indicated that tertiapin is a potent blocker of certain types of inwardly rectifying K(+) (Kir) channels (). We examined the effect of tertiapin on ion channel currents

It is well known that vagal nerve tone plays a crucial role in atrial fibrillation (AF). Acetylcholine-activated potassium current (IKACh) mediates much of the cardiac response to vagal nerve stimulation (VNS), but the contribution of IKACh to AF remains unknown.
