Biological Activity
IC50: 0.1 μM (IK.ACh)[1]
Pirmenol (1 μM) inhibits the IK.ACh induced by carbachol or intracellular loading of GTPg S in in atrial cells[1].
Pirmenol (5 μM) depresses the early part of the plateau and lengthened the final repolarization of the action potentials in ventricular myocytes[3].
Pirmenol (1 μM) prolongs the action potential duration at 90% repolarization in atrial muscles and Purkinje fibers[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Pirmenol (rats) shows LD50s of 359.9 mg/kg (p.o), 23.6 mg/kg (i.v.)[2].
Pirmenol (mice) shows LD50s of 215.5 mg/kg (p.o), 20.8 mg/kg (i.v.)[2].
