Azimilide dihydrochloride
Based on 2 publication(s) in Google Scholar
Azimilide (NE-10064) dihydrochloride is a class III antiarrhythmic agent, which works by blocking potassium channels in the heart. Azimilide dihydrochloride is a dual blocker of IKs (IC50 = 2.6 μM (2mM [K⁺]ₑ)) and IKr (IC50 = 1 μM (4 mM [K⁺])). Azimilide dihydrochloride blocked HERG channel at 0.1 and 1 Hz with IC50s of 1.4 μM and 5.2 μM respectively. Azimilide dihydrochloride also inhibits L-type calcium current (ICa) (IC50 = 17.8 μM) and sodium current (INa) (IC50 = 19 μM). Azimilide dihydrochloride can be used for the study of atrial fibrillation and ventricular fibrillation.

Azimilide dihydrochloride (0.1-100 μM) blocks IKr (reversibly dependent, affected by [K⁺]ₑ) and IKs channels (dependently on use, unaffected by [K⁺]ₑ) in mouse AT-1 cells and African clawed frog oocytes[1].
Azimilide dihydrochloride (0.3-5 μM) shortens the action potential duration (APD) of canine and guinea pig ventricular muscle cells[2][3].

Animal Model:VT model induced by PES established in male mongrel dogs weighing 14.5-21.5 kg[4]
-
Dosage:10 mg/kg
-
Administration:Intravenous injection (i.v.), single dose
-
Result:Significantly reduced the incidence of VT induced by PES.
Prolonged the effective refractory period of the ventricle and the QTc interval, but does not affect the conduction parameters.
Provided significant protection against ischemia-induced ventricular fibrillation and improves survival rates.
