Molarity Calculator

Firibastat (QGC001), an orally active brain penetrating proagent of EC33, is a first-in-class brain aminopeptidase A (APA) inhibitor (Ki=200 nM). Firibastat selectively and specifically inhibits conversion of brain angiotensin-II into angiotensin-III and decreases blood pressure in hypertensive rats.

Description

Firibastat (QGC001), an orally active brain penetrating proagent of EC33, is a first-in-class brain aminopeptidase A (APA) inhibitor (Ki=200 nM). Firibastat selectively and specifically inhibits conversion of brain angiotensin-II into angiotensin-III and decreases blood pressure in hypertensive rats[1][2].

In Vivo

When given orally, Firibastat (0.1-30 mg/kg; p.o.) crosses the gastrointestinal and blood-brain barriers, enters the brain, and generates two active molecules of EC33 which inhibit brain APA activity, blocking brain angiotensin III formation, and decrease blood pressure for several hours in hypertensive rats[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Normotensive and hypertensive DOCA-salt rats[1]
Dosage: 0.1-30 mg/kg
Administration: P.o.
Result: Resulting in a dose-dependent decrease in mean arterial blood pressure (MABP).

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.
