Description of Nordihydroguaiaretic acid

Nordihydroguaiaretic acid is a potent 5-lipoxygenase (5-LOX) inhibitor with an IC50 value of 8μM [1]. Nordihydroguaiaretic acid blocks production of leukotriene B4, degranulation, phagocytosis, and the respiratory burst by exerting effects on the mitochondria and nonspecifically inhibiting NADPH oxidase and protein kinase C [2]. Nordihydroguaiaretic acid has been widely used as an antioxidant to prevent the harmful effects of reactive oxygen species (ROS)[3].

In vitro, Nordihydroguaiaretic acid treatment for 24 hours significantly inhibited the growth of HepG2 cells, with an IC50 value of 45.646μM[4]. Treatment with 20μM Nordihydroguaiaretic acid for 24 hours significantly inhibited the migration of PC3 cells and reduced the expression of NRP1[5]. 10μM of Nordihydroguaiaretic acid pre-incubation for 1 hour blocked the increase in junB expression in the TGF-β-induced ROS17/2.8 cells and inhibited the nuclear translocation of Smad proteins[6].

In vivo, Nordihydroguaiaretic acid treatment via oral administration at a dose of 2.5g/kg/day for 16 weeks resulted in a significant decrease in body weight and rectal temperature in ob/ob mice, and promoted a significant reduction in serum triglyceride (TG) and glucose levels[7]. Intraperitoneal injection of Nordihydroguaiaretic acid at a dose of 750μg five times a week for 3 weeks significantly inhibited tumor growth and promoted cancer cell apoptosis in SW 850 xenograft mice[8].

Protocol of Nordihydroguaiaretic acid

Cell experiment [1]:

Cell lines

HepG2 cells

Preparation Method

HepG2 cells were incubated in DMEM medium supplemented with 10% fetal calf serum (FCS) in a humidified atmosphere at 37°C with 5% CO2. Cells were cultured in a 96-well culture plate at 1×104 cells/well. After 24h cultured at 37°C in the atmosphere of 5% CO2, cells were adhered to and treated with different concentrations of Nordihydroguaiaretic acid (0, 10, 30, 50, 80, 100, 120, and 150μM) and incubated for 24h. Cell proliferation was measured.

Reaction Conditions

0, 10, 30, 50, 80, 100, 120, and 150μM; 24h

Applications

Nordihydroguaiaretic acid treatment significantly reduced the cell proliferation of HepG2 cells in a dose-dependent manner.
Animal experiment [2]:

Animal models

Male leptin-deficient (ob/ob) mice

Preparation Method

Male ob/ob mice were fed a standard chow diet for 1 week to acclimatize to a controlled environment (25±2°C; 55±5% relative humidity with a 12h light-dark cycle). Subsequently, one group of ob/ob mice was switched to a chow diet supplemented with 2.5g/kg/day Nordihydroguaiaretic acid and maintained on the diet for 16 weeks. Food intake and body weight were measured once a week throughout the experiment. Liver samples were collected from mice for analysis.

Dosage form

2.5g/kg/day for 16 weeks; i.p.

Applications

Nordihydroguaiaretic acid treatment significantly decreased the body weight of ob/ob mice and improved aberrant hepatic lipid metabolism in ob/ob mice.
