The chromatogram was analysed using the program Agilent ChemStation (Agilent Technologies, Madrid). These compounds were solubilised by adding 2% (v/v) DMF to the reaction medium. Melanocytes control the melanin production - melanin is responsible for the pigment levels which imparts the skin its colour. (For better or for worse.) July 25, 2005. Instability of the o-quinone produced by the action of tyrosinase on -arbutin. Alpha Arbutin contains 0.5% Squalane. Applied topically, it inhibits tyrosinase and thus prevents the formation of melanin. While alpha arbutin is safe to mix into creams and lotions in small doses, it must always be dissolved in water first. However, they can be attacked by a hydrazone such as MBTH, giving rise to adducts, which are oxidized to become into stable chromophores with a high molar absorptivity (S1A Fig), absorbing between 350 nm and 600 nm. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. You need 5-parts water for every 1-part alpha arbutin. In order to maintain the depigmenting power of the hydroquinone, while decreasing its cytotoxicity, some derivatives of this compound such as -arbutin (2R,3S,4S,5R,6R)-2-(hydroxymethyl)-6-(4-hydroxyphenoxy)oxane-3,4,5-triol) and -arbutin (2R,3S,4S,5R,6S)-2-(hydroxymethyl)-6-(4-hydroxyphenoxy)oxane-3,4,5-triol), a glycosylated hydroquinones, have been used (Fig 1) [18]. trailer << /Size 52 /Info 24 0 R /Encrypt 28 0 R /Root 27 0 R /Prev 110658 /ID[<32fd81134a27539250598fd3e5481ddb><4199f6c65f7770df92df5ed52db83b01>] >> startxref 0 %%EOF 27 0 obj << /Type /Catalog /Pages 23 0 R /Metadata 25 0 R /PageLabels 22 0 R >> endobj 28 0 obj << /Filter /Standard /R 2 /O (yU?m5LI\)XLv:/wx) /U (9g=7zGTh'zSMM) /P -60 /V 1 /Length 40 >> endobj 50 0 obj << /S 136 /L 224 /Filter /FlateDecode /Length 51 0 R >> stream Conditions are described in Materials and Methods.

S7 Fig. Its not destroying melanin, but instead, its changing its production. Subsequently, the same authors show that -arbutin does not inhibit the growth of cultured human melanoma cells, HMV-II, but it does inhibit melanin synthesis, meaning that the use -arbutin in cosmetics is effective and safe for treating hyperpigmentation disorders [30]. In conclusion, this work demonstrate that and -arbutin act as substrates of tyrosinase, since the enzyme is able to hydroxylate them and, subsequently, to oxidize the originated o-diphenol, as well as the hydroquinone, whose quinones are cytotoxic especially when they act on thiol compounds in the melanosome. An active agent in brands of skin lightening preparations, it is more expensive than traditional skin lightening ingredients like hydroquinone, which is now banned in many countries. Alpha arbutin can be used to diminish age spots, post-blemish redness and acne. The action of tyrosinase on hydroquinone has been characterized kinetically recently [13,20]. Moreover, when these compounds are studied as substrates of the enzyme, the Kd values obtained by docking studies are in the same range as the KM values (Table 2). In addition, synthetic arbutin can be dangerous since it may break down into carcinogenic chemicals. For its part, -arbutin is obtained principally by enzymatic synthesis from hydroquinone or -arbutin [21,22].
