Etamicastat (BIA 5-453) is a potent and reversible dopamine-β-hydroxylase (DBH) inhibitor with an IC50 value of 107 nM. Etamicastat can be used in the research of cardiovascular diseases.

At equivalent molar concentrations, both the salt and free forms of a compound exhibit comparable biological activity. Nevertheless, the salt form (Etamicastat hydrochloride) usually boasts enhanced water solubility and stability.

Description

Etamicastat (BIA 5-453) 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].

IC50 & Target

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
