Description

(R)-Trolox is a 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].

In Vitro

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].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.25 mg/mL (8.99 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.25 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (22.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.25 mg/mL (8.99 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.25 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (22.5 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
