IC50: 107 nM (DBH)[1]

In Vitro Etamicastat blocks the hERG current amplitude with an IC50 value of 44 μg/mL (141 μM)[2].
In Vivo 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]. Animal Model: NMRi mice[1] Dosage: 100 mg/kg Administration: Administered intraperitoneally Result: Led to a significant reduction of noradrenaline levels (36% control) in heart with concomitant increasing in dopamine levels (850% of control). Animal Model: Male Wistar rats[1] Dosage: 50 mg/kg (Pharmacokinetic Analysis) Administration: Orally administered with at a dose volume of 10 mL/kg Result: Oral bioavailability (64%), Cmax (4.9 nM), and (T1/2=3.7 h).
