Description

Masoprocol (meso-Nordihydroguaiaretic acid) is a potent and orally active lipoxygenase inhibitor. Masoprocol shows antihyperglycemic activity. Masoprocol decreases the glucose concentration and hepatic triglyceride in vivo. Masoprocol has the potential for the research of type II diabetes[1][2][3].

In Vitro

Masoprocol (30 μM; 90 min) shows high basal and insulin-stimulated glucose clearance in adipocytes[2].

In Vivo

Masoprocol (150 mg/kg; i.g.; twice a day for 12 days) shows antihyperglycemic activity with the decreases in glucose concentration in plasma in male C57BL/ks-db/db mice[1]. Masoprocol （0.83 mmol/kg; twice a day for 4 days）shows low glucose concentrations an average of 35% and low triglyceride concentrations of 80% compared with the vehicle at a rat model of type II diabetes[2]. Masoprocol (40-80 mg/kg; p.o.; twice daily for 8 days) significantly reduces hepatic triglyceride (TG) secretion (P<.01) and liver TG content in a nondiabetic rat model with dietary-induced hypertriglyceridemia(HTG)[3].

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    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (8.27 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

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

    Solubility: ≥ 2.5 mg/mL (8.27 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

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.
