Description

Prifuroline is an agent of antiarrhythmic.

In vivo

Prifuroline dose-dependently antagonizes the arrhythmogenic action of aconitine in rats, when administered either intravenously (5, 10 or 20 mg/kg) or intraduodenally (10, 20 or 50 mg/kg);?it exhibits effectiveness by the digestive route at doses only twice as greater as the active i.v. doses: its intravenous anti-aconitine activity is comparable to that of disopyramide, and superior to that of quinidine;?lidocaine is inactive in this test.Prifuroline also diminishes ventricular susceptibility to electrical stimulation in open-chest rats;?its effect is comparable to that of disopyramide and amiodarone at the same dose levels;?quinidine and lidocaine are less effective.?Only prifuroline and propranolol were able to antagonize ouabain toxicity in guinea-pigs, quinidine showing only borderline activity, and disopyramide, lidocaine and verapamil being ineffective.?In a model of arrhythmias induced by anoxic stress in rats, all the tested compounds were found active, with prifuroline and disopyramide providing complete protection at high dose levels.?The arrhythmias induced in dogs by coronary artery ligation were markedly antagonized by prifuroline after doses of 5 and 10 mg/kg i.v. or 30 mg/kg intraduodenally;?the duration of its antiarrhythmic activity in this model of arrhythmias in conscious dogs was much longer after intraduodenal than after i.v. administration.?Prifuroline was also able to restore sinus rhythm in guinea-pigs after intracardiac conduction blockade with acetylcholine, although being devoid of anticholinergic activity.?It also diminishes the maximal frequency of guinea-pig atria electrically stimulated in viro (EC25 = 5 X 10(-6) g/ml).

Molarity Calculator allows you to calculate the

Mass of a compound required to prepare a solution of known volume and concentration
Volume of solution required to dissolve a compound of known mass to a desired concentration
Concentration of a solution resulting from a known mass of compound in a specific volume

See Example

An example of a molarity calculation using the molarity calculator
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
Enter 197.13 into the Molecular Weight (MW) box
Enter 10 into the Concentration box and select the correct unit (millimolar)
Enter 10 into the Volume box and select the correct unit (milliliter)
Press calculate
The answer of 19.713 mg appears in the Mass box

Calculate the dilution required to prepare a stock solution
The dilution calculator is a useful tool which allows you to calculate how to dilute a stock solution of known concentration. Enter C1, C2 & V2 to calculate V1.

See Example

An example of a dilution calculation using the Tocris dilution calculator
What volume of a given 10 mM stock solution is required to make 20ml of a 50 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=50 μM, V2=20 ml and V1 is the unknown:
Enter 10 into the Concentration (start) box and select the correct unit (millimolar)
Enter 50 into the Concentration (final) box and select the correct unit (micromolar)
Enter 20 into the Volume (final) box and select the correct unit (milliliter)
Press calculate
The answer of 100 microliter (0.1 ml) appears in the Volume (start) box
