Methylhydroquinone is an orally active COX inhibitor with IC₅₀s of 480.7 μM and 52.2 μM for ovine COX-1 and human recombinant COX-2, respectively. Methylhydroquinone has potential DNA damaging effects: 1) inhibiting COX-1 to reduce prostaglandin synthesis and exert anti-inflammatory activity; 2) inducing DNA single-strand breaks. Methylhydroquinone exerts its effects by competitively binding to the active sites of COX-1 (such as Tyr385, Met522) and non-covalent interactions.

In Vivo

Methylhydroquinone (200 mg/kg; gastric intubation, single dose) induces DNA single-strand breaks and increases ornithine deoxycholate (ODC) activity and repetitive DNA synthesis (RDS) in rat gastric pyloric mucosa^[2].

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

Animal Model:	Gastric Pyloric Mucosa Injury Model in Male F344 rats (7 weeks old, 25-30 g)
Dosage:	200 mg/kg (aqueous solution)
Administration:	Single gastric intubation (2 h prior to sacrifice)
Result:	Significantly increased DNA single-strand breaks) in the pyloric mucosa 2 h post-administration, but did not induce detectable unscheduled DNA synthesis (UDS). Weakly promoted tumorigenesis by increasing ornithine decarboxylase (ODC) activity (6-fold) and replicative DNA synthesis (RDS) at 24 h and 16 h, respectively.

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: ≥ 5 mg/mL (40.28 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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: ≥ 5 mg/mL (40.28 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 5 mg/mL (40.28 mM); Clear solution

This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 900 μL Corn oil, and mix evenly.
