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].

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

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].

储备液的保存方式和期限：-80°C, 6 months; -20°C, 1 month (protect from light)。-80°C储存时，请在6个月内使用，-20°C储存时，请在1个月内使用。

• 方案 一

  请依序添加每种溶剂： 10% DMSO    40% PEG300    5% Tween-80    45% Saline

  Solubility: ≥ 2.5 mg/mL (8.27 mM); 澄清溶液

  此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液。

  以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；再向上述体系中加入 50 μL Tween-80，混合均匀；然后再继续加入 450 μL 生理盐水 定容至 1 mL。

  生理盐水的配制：将 0.9 g 氯化钠，溶解于 ddH₂O 并定容至 100 mL，可以得到澄清透明的生理盐水溶液。

• 方案 二

  请依序添加每种溶剂： 10% DMSO    90% (20% SBE-β-CD in Saline)

  Solubility: ≥ 2.5 mg/mL (8.27 mM); 澄清溶液

  此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液。

  以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中，混合均匀。

  20% SBE-β-CD in Saline 的配制（4°C，储存一周）：2 g SBE-β-CD（磺丁基醚 β-环糊精）粉末定容于 10 mL 的生理盐水中，完全溶解至澄清透明。

• 方案 三

  请依序添加每种溶剂： 10% DMSO    90% Corn Oil

  Solubility: ≥ 2.5 mg/mL (8.27 mM); 澄清溶液

  此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液，此方案实验周期在半个月以上的动物实验酌情使用。

  以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中，混合均匀。
