(R)-Trolox is a water soluble vitamin E analogue and a competitive tyrosinase inhibitor with a Ki value of 0.83 mM and a ID50 value of 1.88 mM[1]. The (R)-Trolox has stronger tyrosinase affinity than the (S) enantiomer (Ki value of 0.61 mM)[1].
As compared to the control containing no inhibitor, DMSO suppresses the tyrosinase activity at tested levels, 100 and 200 µL in a total volume of 3.0 mL. The inhibition of DMSO on the mushroom tyrosinase is dosedependent. Additions of DMSO at the two levels in the tyrosinase digests containing (R)-Trolox ((R)-HTCCA) results in further inhibitions of the tyrosinase activity. The influence of the DMSO on the inhibitory effects of (R)-Trolox against the tyrosinase is also dose-dependent[1].
