Scripps Howard News Service. Taking into account that the assay without arbutin does not have a lag period due to the addition of L-dopa (in catalytic amounts ([D] / [M] = 0.042 [1,61]), when -arbutin is added, the activity rate of the enzyme on L-tyrosine varies (Fig 2A Inset). Furthermore, the IC50 values for monophenolase (Fig 2) and diphenolase (Fig 3) activities were not the same, and neither were the apparent inhibition constants (Fig 4 and S3 Fig), as can be seen in Table 1. Spectrophotometric recordings of the effect of different concentrations of -arbutin on the diphenolase activity of tyrosinase, using L-dopa as substrate. Applied topically, it inhibits tyrosinase and thus prevents the formation of melanin.

The data agree with those from docking studies that showed that the enzyme has a higher affinity for -arbutin. Spectrophotometric recordings of the effect of different concentrations of -arbutin on the diphenolase activity of tyrosinase, using L-dopa as substrate. However, if 3-methyl-2-benzothiazolinone hydrazone hydrochloride hydrate is used, the o-quinone is attacked, so that it becomes an adduct, which can be oxidized by another molecule of o-quinone, generating o-diphenol in the medium.

It helps reducing hyperpigmentation and other dark spots. In this video, I will compare 2 Alpha Arbutin 2% + HA bottles. A study on the action of arbutin on tyrosinase and the rest of the enzymes involved in the melanogenesis process showed that this compound does not change the molecular size or the content of tyrosinase, DHICA oxidase (TRP1) or dopachrome tautomerase 2 (TRP2), but that inhibition might affect the process at the post-translational level [25]. The active admixture is a dermatological serum comprised of alpha arbutin, octyl stearate and polyolprepolymer-2, introduced onto the human skin in liposome form for ultra-deep penetration.

The ortho carbon is found 3.7 from an oxygen atom of the peroxide ion, close enough to allow substrate hydroxylation by the monophenolase activity. The higher affinity of -arbutin could be explained by the additional conformational stability of the glucopyranose ring provided by three anchor points to the protein compared with two in -arbutin. Though beta-arbutin is cheaper than alpha-arbutin, it is more likely to inhibit skin cell growth. Arbutin is less toxic than hydroquinone and less irritation.
