| Targets |
AVE-0118 targets Kv1.5 potassium channels and other ion channels. It is a nonselective Kv1.5 blocker. By blocking Kv1.5 and other channels, it prolongs atrial refractoriness and suppresses atrial fibrillation. It dose-dependently prolongs the atrial refractoriness independent of rate and inhibits left atrial vulnerability (LAV) in vivo. AVE-0118 effectively suppressed acetylcholine-mediated persistent atrial fibrillation.

| ln Vitro |
AVE-0118 is a Kv1.5 blocker (IC50 = 1.1 uM) that has good activity against IKs, IK1, and IKATP Stability AVE-0118 (10 μM) and medium breadth against Ito (3.4 uM), IKr (8.4 uM), and IKAch (4.5 uM) [2]. It also greatly increases neurogenic contractions caused by stimulation (EFS).
In vitro, AVE-0118 is a nonselective Kv1.5 blocker with an IC₅₀ of 1.1 μM. It is a multichannel inhibitor with weak, micromolar activity against Kv1.5 and other ion channels. It is inactive against IKs, IKATP, and L-type Ca²⁺ channels. It inhibits human ERG with an IC₅₀ value of 10000.0 nM. |
| ln Vivo |
At doses of 3 mg/kg and 5 mg/kg, AVE-0118 decreased the inducibility of atrial remodeling in goats but did not extend QTc [1].
In vivo, at a dose of 3 mg/kg, AVE-0118 reduced the inducibility of AF in a goat model of atrial remodeling, and at 5 mg/kg it did not prolong QTc. It fully restored atrial contraction without proarrhythmic effects on the ventricle. AVE-0118 functions without apparent effect on ventricular repolarization. The atrial selective and dose-dependent prolongation of atrial refractoriness likely contributes to the effectiveness of AVE-0118 to suppress atrial fibrillation. |
| Enzyme Assay |
The activity of AVE-0118 can be assessed using electrophysiological techniques, specifically patch-clamp electrophysiology. Cells expressing Kv1.5 channels are treated with varying concentrations of AVE-0118. The potassium currents are recorded, and the IC₅₀ for channel blockade is determined from dose-response curves. Selectivity over other ion channels is assessed using similar assays.
|
| Cell Assay |
To evaluate the cellular effects of AVE-0118, cardiomyocytes or cells expressing Kv1.5 channels are treated with the compound. The inhibition of potassium currents and its effects on action potential duration are measured using electrophysiological recordings. The compound's effects on cell viability and contractility can also be assessed.
|
| Animal Protocol |
In vivo studies with AVE-0118 typically involve administration to animal models via intravenous or oral routes. In models of atrial fibrillation (e.g., goat model of atrial remodeling), the compound's effects on AF inducibility and duration are assessed. Its effects on atrial and ventricular refractoriness are evaluated using electrophysiological mapping. Pharmacokinetic parameters, such as bioavailability and half-life, are also characterized.
|
| ADME/Pharmacokinetics |
AVE-0118 has a molecular formula and weight that are not specified in the available literature. Its CAS number is 498577-53-0. It is a potassium channel blocker. It is soluble in DMSO and other organic solvents. The purity is typically >98%. It should be stored according to the manufacturer's instructions.
|
| Toxicity/Toxicokinetics |
Specific toxicology data for AVE-0118 are not extensively detailed in the available literature. However, its use in animal models at effective doses suggests a degree of tolerability. As with all research compounds, standard safety precautions should be taken when handling AVE-0118. It is intended for research use only and is not for human consumption.
