Ipravacaine
Ipravacaine (IQB-9302) is a long-acting amide-based local anesthetic. Ipravacaine blocks open-state hKv1.5, with stereoselective, time-dependent and voltage-dependent inhibitory effects, and exerts stronger activity on the R (+) enantiomer. Ipravacaine blocks Kv2.1, Kv4.3 and HERG potassium channels. Ipravacaine induces negative chronotropic effects, increases mean arterial pressure, and exhibits vasodilatory effects at high concentrations.

Biological Activity
Ipravacaine (10-500 μM; ~12 min) exerts stereoselective, time- and voltage-dependent open-channel block on hKv1.5 channels stably expressed in Ltk7 cells, with R (+) Ipravacaine (KD=17.8 μM) being 3.2 times more potent than S (-) Ipravacaine (KD=58.6 μM)[1].
The molecularly simulated aromatic ring-overlapping conformers of R (+) and S (-) Ipravacaine have N-substituents with opposite orientations, which explains their stereoselective blocking effect on hKv1.5 channels[1].

Animal Model:Sprague-Dawley (3-month-old, 250-350 g, sex-matched, anaesthetised with sodium pentobarbital)[3]
-
Dosage:0.1 mg/kg; 0.3 mg/kg; 1 mg/kg; 3 mg/kg; 10 mg/kg
-
Administration:i.v.; over 30 seconds, followed by 100 μl heparinised sodium chloride infusion over 15 seconds; every 20 minutes
-
Result:Produced a maximum decrease in heart rate of 114 bpm.
Produced a maximum increase in mean arterial pressure of 20.7 mmHg.
Caused all exposed rats to die within 2 minutes at 10 mg/kg, with all surviving more than 1.5 minutes post-dose.
Was well-tolerated without mortality at 3 mg/kg.
