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

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.

α-Arbutin is a glycosylated hydroquinone which has inhibitory function against tyrosinase. In this work, a one-step isolation of α-arbutin from Xanthomonas CGMCC 1243 fermentation broth by macroporous resin adsorption chromatography was investigated. The research results indicated that S-8 resin offered

Arbutin, which is found in the genus Arctostaphylos, is an anti-oxidant and a depigmenting agent. The present study was designed to validate the anti-inflammatory effect of arbutin. The anti-inflammatory properties of arbutin were studied using a lipopolysaccharide (LPS)-stimulated murine BV2

Two natural acetophenone derivatives, 2,5-dihydroxyacetophenone (2,5-DHAP) and 2,6-DHAP, were purified from Cynanchum bungei and identified as murine tyrosinase inhibitors. Investigation into 2,5-DHAP showed it to be an uncompetitive inhibitor of murine tyrosinase (K(I) 0.28 mm). 2,5-DHAP strongly inhibited both melanogenesis and
