Etamicastat hydrochloride (BIA 5-453 hydrochloride) is a potent and reversible dopamine-β-hydroxylase (DBH) inhibitor with an IC50 value of 107 nM[1]. Etamicastat can be used in the research of cardiovascular diseases[2].
Etamicastat blocks the hERG current amplitude with an IC50 value of 44 μg/mL (141 μM)[2].
Etamicastat (100 mg/kg; administered intraperitoneally) leads to a significant reduction of noradrenaline levels in heart with concomitant increasing in dopamine levels[1].
Etamicastat (50 mg/kg; a single oral administration) exhibits moderate oral bioavailability (64%), Cmax (4.9 nM), and terminal elimination half-lives (T1/2=3.7 h) in male Wistar rats[1].
