Common Name(s): Phloridzin,phloridzin,apple bark dihydrochalcone,sglt2 inhibitor brightening anti-glycation active

CAS Number: N/a

DESCRIPTION

What It Does: Provides sglt-mediated glucose transport reduction for anti-glycation protection of skin collagen, tyrosinase inhibitory brightening from the dihydrochalcone pharmacophore, and potent antioxidant radical scavenging.

Why It's Used: Phloridzin is historically significant as the first compound to demonstrate sglt inhibition (1835) โ€” the same mechanism later developed into the gliflozin pharmaceutical class. topically, the sglt inhibition reduces keratinocyte glucose uptake reducing local glycation of sc proteins.

How It Works: Phloridzin: competitive sglt1/2 inhibition (kd ~200 nm) โ†’ reduced intracellular glucose โ†’ reduced maillard reaction on skin proteins โ†’ anti-glycation. phloretin aglycone (from skin glucosidase hydrolysis): competitive tyrosinase inhibition (ic50 ~30 ฮผm) โ†’ brightening. dihydrochalcone alpha,beta-unsaturated carbonyl: radical scavenging from phenol h-atom donation.

SCIENTIFIC NOTE

Phloridzin bioavailability: skin glucosidase converts phloridzin to phloretin aglycone (ic50 30 ฮผm tyrosinase โ€” stronger than arbutin) โ€” the glycoside providing better aqueous solubility and formulation stability than direct phloretin with skin-mediated activation providing the more potent aglycone at the delivery site.
