In Vitro

Thymoquinone (20-100 μM, 24-72 h) has anti-proliferation and pro-apoptotic activity in non-small cell lung cancer SCLC cell lines, and has a synergistic effect with Cisplatin (CDDP) (HY-17394) ^[3].
Thymoquinone (100 nM, 24 h) inhibits VEGF expression in HUVECs cells through the VEGFR2/PI3K/Akt signaling pathway^[5].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Proliferation Assay^[3]

Cell Line:	SCLC cell line NCI-H146
Concentration:	20-100 μM
Incubation Time:	24-72 h
Result:	Thymoquinone of 80 and 100 μM showed significant inhibition of cell proliferation, most pronounced at 24 hours. The effect of Thymoquinone alone on cell proliferation diminished over time.

In Vivo

Thymoquinone (5-20 mg/kg/day for 3 days, i.p.) can play a protective role against hepatotoxicity induced by paraquat by activating SOD inhibition mediated by paraquat^[1].
Thymoquinone (10 mg/kg/day for 5 days, p.o.) can protect against Doxorubicin (HY-15142A)-induced cardiotoxicity in rats through superoxide clearance and anti-lipid peroxidation^[2].
Thymoquinone (5-20 mg/kg subcutaneously (s.c.) on Monday, Wednesday and Friday for 3 weeks) alone can effectively reduce the tumor volume of NCI-H460 mouse xenograft model, overcome Cisplatin (CDDP) (HY-17394) resistance, and improve its efficacy ^[3].
Thymoquinone (10 or 20 mg/kg/day for 15 days, i.g.) could clear Aβ plaques and restore neuronal vitality, which could improve the memory ability of Aβ1-42 perfusion rats^[4].
Thymoquinone (single 3 mg/kg, i.p.) down-regulates the VEGFR2-PI3K-Akt pathway and inhibits inflammation and new angiogenesis in asthmatic mice^[5].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Male albino mice (22-27g), Paraquat-induced hepatotoxicity in mice^[1]
Dosage:	5-20 mg/kg/day for 3days
Administration:	i.p.
Result:	Significantly reduced the level of LPO and restored the endogenous antioxidant capacity of liver tissue. Restored SOD activity inhibited by Paraquat. Thymoquinone’s optimum, safe, and protective dose against Paraquat-hepatotoxicity is about 10 mg/kg, which is comparable to the antioxidant properties of Vitamin E.

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 (15.23 mM); Clear solution

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

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 (15.23 mM); Clear solution

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 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (15.23 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

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.
