Common Name(s): Oleuropein aglycone,oleuropein aglycone,olive secoiridoid,potent anti-inflammatory anti-aging active

CAS Number: N/a

DESCRIPTION

What It Does: Provides potent nf-kb and cox-2 anti-inflammatory inhibition from the secoiridoid michael acceptor, exceptional antioxidant protection from the catechol enol (orac >70 ฮผmol te/mg), and tyrosinase cuยฒโบ chelation for brightening.

Why It's Used: Oleuropein aglycone is more potent than the glucoside form by 10-50ร— โ€” the beta-glucosidase-released aglycone's enol tautomer providing the michael acceptor pharmacophore for covalent anti-inflammatory enzyme inhibition unavailable from the protected glucoside.

How It Works: Oleuropein โ†’ beta-glucosidase โ†’ oleuropein aglycone (1:1 mixture of dialdehydic and cyclic forms). aglycone michael acceptor: covalent ikk-ฮฒ cys179 adduct โ†’ nf-ฮบb blocked; cox-2 active-site michael addition โ†’ prostaglandin inhibition. catechol + enol: orac >70 ฮผmol te/mg. catechol cuยฒโบ chelation โ†’ tyrosinase inhibition.
