Application

Arbutin, a glycosylated hydroquinone, is used in studies on melanin biosynthesis and as an inhibitor to identify, differentiate and characterize tyrosinase(s).

Biochem/physiol Actions

Arbutin is a glycosylated hydroquinone used in traditional Chinese medicine (TCM). Arbutin inhibits melanin formation due to its tyrosinase inhibitory activity.

Tyrosinase (TYR) catalyzes rate-limiting steps of melanogenesis and thus its inhibitors are potentially useful as hypopigmenting agents. Recently, p-coumaric acid (p-CA) has been suggested to interfere with the pro-melanogenic actions of tyrosine due to its structural similarity with tyrosine (An

Facial hyperpigmented disorders are a common complaint in the adult population of all races. First-line topical treatments are usually hydroquinone or topical retinoids, which can cause irritant reactions. The need for better tolerated, yet effective, skin lightening agents that could

A possible role for metabolism by the human intestinal microflora in arbutin-induced cytotoxicity was investigated using human hepatoma HepG2 cells. When the cytotoxic effects of arbutin and hydroquinone (HQ), a deglycosylated metabolite of arbutin, were compared, HQ was more toxic

α-Arbutin (α-Ab) is a powerful skin whitening agent that blocks epidermal melanin biosynthesis by inhibiting the enzymatic oxidation of tyrosine and L-3,4-dihydroxyphenylalanine (L-DOPA). α-Ab was effectively synthesized from hydroquinone (HQ) by enzymatic biotransformation using amylosucrase (ASase). The ASase gene from

A carboxyl group-terminated polyamidoamine dendrimer (generation: 3.0) bearing arbutin, which is a substrate of Na⁺/glucose cotransporter 1 (SGLT1), via a nonbiodegradable ω-amino triethylene glycol linker (PAMAM-ARB), inhibits SGLT1-mediated D-glucose uptake, as does phloridzin, which is a typical SGLT1 inhibitor.
