Application

Glabridin has been used:
  • to analyze its transthyretin (TTR)-stabilizing effect in plasma of healthy volunteers
  • as a standard in proton nuclear magnetic resonance (1H NMR) to study the interaction between glabridin and human serum albumin using multi-spectroscopic and molecular docking techniques
  • to study its effect on nucleotide-binding oligomerization domain-like receptor pyrin-domain-containing protein 3 (NLRP3) inflammasome activation

Biochem/physiol Actions

Glabridin is a bio-available isoflavan isolated from licorice (Glycyrrhiza glabra L.) root extract. Glabridin has been reported to possess various biological activities including strong antioxidant activity, antioxidant against LDL oxidation, anti-Helicobacter pylori properties, estrogen-like activity and antinephritic and radical scavenging activities. Also it appears to inhibit serotonin re-uptake, melanogenesis, inflammation and cytochrome P450 3A4, 2B6, and 2C9.
Glabridin is a main component of glavonoid, also known as licorice-derived flavonoid oil, which is a natural supplement used in traditional medicine and herbal medicine.

Transthyretin (TTR) is an amyloidogenic protein associated with hereditary and nonhereditary transthyretin amyloidoses (ATTR). Dissociation of the tetramer of TTR to the monomer induces TTR misfolding, which leads to amyloid fibril formation and triggers the onset of ATTR amyloidosis. Stabilizers
