Tertiapin Q Chemical Properties,Usage,Production

Uses

Tertiapin-Q is a highly selective blocker of GIRK1/4 heterodimer and ROMK1 (Kir1.1).

Biochem/physiol Actions

Blocks the GIRK1/4 and ROMK1 members of the inward-rectifier K+ channel family.

in vivo

Tertiapin-Q is a muscarinic acetylcholine receptor-operated K⁺ current (I_K,Ach) blocker. After the cessation of rapid atrial pacing, the atrial effective refractory period (AERP) is unchanged during the experimental period in the rapid atrial pacing (RAP) rabbits (n=6). Bepridil (1 mg/kg, n=5 for each group), Amiodarone (10 mg/kg, n=5 for each group), Vernakalant (3 mg/kg, n=5 for each group), Ranolazine (10 mg/kg, n=6 for each group) or Tertiapin-Q (0.03 mg/kg, n=5 for each group) on the AERP in the control and RAP rabbits. Tertiapin-Q significantly prolongs the AERP at each pacing cycle length both in the control and RAP rabbits. The extents of prolonging effect of Tertiapin-Q on the AERP in the RAP rabbits are greater than those in the control animals^[3].
