Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

In vitro	Thymoquinone (TQ) strongly inhibits the production of nitric oxide (NO) and repressed NO synthase (iNOS), tumor necrosis factor (TNF)-α, cyclooxygenase (COX)−2, interleukin (IL)−6, and IL-1β expression in LPS-activated RAW264.7 cells. TQ acts as a radical scavenger and thereby preserves the enzymatic activity of antioxidants like catalase, glutathione peroxidase, and glutathione-S-transferase. TQ abolishes the activity of IRAK1, but not IRAK4, thereby reducing the activity of downstream NF-κB and AP-1^[1]. Treatment with TQ significantly decreases cell viability in COLO205 and HCT116 cells in a dose-dependent manner. TQ treatment significantly decreases the level of phosphorylated p65 in the nucleus, which indicates the inhibition of NF-κB activation by TQ treatment. Treatment with TQ also decreases the expression levels of VEGF, c-Myc and Bcl-2^[2].
In vivo	Treatment of LPS/D-GalN–induced hepatitis and EtOH/HCl–induced gastritis mouse models with TQ significantly ameliorates disease symptoms^[1].
