IC50 & Target[1]

COX-1

6.5 μM (IC50, in human whole blood)

COX-2

13.5 μM (IC50, in human whole blood)

体外実験

Loxoprofen, an anti-inflammatory prodrug (NSAID), is a nonselective COX inhibitor with IC50s of 6.5 and 13.5 μM for COX-1 and COX-2 in human whole blood assays, respectively[1].
Loxoprofen (LOX) is a non-selective cyclooxygenase inhibitor that is widely used for the reasearch of pain and inflammation caused by chronic and transitory conditions. Its alcoholic metabolites are formed by carbonyl reductase (CR) and they consist of trans-LOX, which is active, and cis-LOX, which is inactive. In addition, LOX can also be converted into an inactive hydroxylated metabolite (OH-LOXs) by cytochrome P450 (CYP)[2].

体内実験

Loxoprofen sodium (4 mg/kg/day; p.o.; 1 or 8 weeks) reduces atherosclerosis in mice by reducing inflammation[3]. Loxoprofen sodium (60 μg/mL; p.o.; 24 days) suppresses mouse tumor growth by inhibiting VEGF[4].

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

Animal Model: ApoE-/- mice (C57BL/6J-Apoetm1Unc) with high-fat diet (0.2% cholesterol, 21% saturated fat) from 8 to 16 weeks of age[3]
Dosage: 4 mg/kg/day in drinking water
Administration: Oral dosing from 8 to 16 weeks of age or from 15 to 16 weeks of age
Result: Inhibited platelet thromboxane production and platelet aggregation. Reduced extent of atherosclerosis. Suppressed the production of PGE2, TxB2 and PGI2.
Animal Model: 6-week-old male C57BL/6 and BDF1 mice, 100 μL suspensions (2 × 106 cells/mL) of LLC cells and KLN205 cells were injected subcutaneously into C57BL/6 and BDF1 mice, respectively[4].
Dosage: 60 μg/mL
Administration: Oral dosing in drinking water, every day for 24 days
Result: Suppressed tumor growth and angiogenesis, suppressed expression of VEGF in mice with LLC tumor, inhibited tubular formation of HUVECs.

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 (10.15 mM); Clear solution

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

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (10.15 mM); Clear solution

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

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.

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.
