| Hazard Information | Back Directory | [Uses]
DPO-1 is a potent inhibitor of the voltage-gated potassium channel subtype Kv1.5 and a blocker of ultrarapid delayed rectifier potassium current. DPO-1 prevents atrial arrhythmia[1][2]. | [Definition]
ChEBI: [[(1S,2S,5R)-5-methyl-2-propan-2-ylcyclohexyl]-phenylphosphoryl]benzene is a monoterpenoid. | [Biological Activity]
Blocker of I Kur ultrarapid delayed rectifier potassium current and K V 1.5 channels (IC 50 = 0.31 μ M for rK V 1.5). Displays selectivity for inhibition of I Kur over I to (8-fold), I K1 , I Kr and I Ks (20-fold) in native myocytes and selectivity for rat recombinant K V 1.5 over K V 3.1 (~ 15-fold). Increases action potential duration in atrial but not ventricular myocytes and prevents atrial arrhythmia. | [storage]
