Description

In Vitro

Orlistat (40 μM; 2 days) does not affect MGMT levels in a human melanoma cell line, but downregulates the repair protein by 30-70% in human peripheral blood mononuclear cells, in two leukemia and two colon cancer cell lines. Orlistat does not alter noticeably MGMT mRNA expression^[1].

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

Western Blot Analysis^[1]

Cell Line:	The human melanoma cell line M10, Peripheral blood mononuclear cells , The human Jurkat CD4⁺ T cell leukemia cell line, the human promyelocytic leukemia cell line HL-60, the epithelial colon cancer HCT116 cells,non adherent mononuclear cells (NAMNC)^[1]
Concentration:	2.5, 5, 10, 20, 40 μM for Jurkat cells; 20 and 40 μM for HCT116 cells; 40 μM for normal NAMNC, M10 melanoma, HL-60 promyelocytic leukemia, and HT-29 colon cancer cells
Incubation Time:	2 days for Jurkat cells; 2 or 4 days for HCT116 cells; 2 days for NAMNC, M10 melanoma, HL-60 promyelocytic leukemia, HT-29 colon cancer
Result:	Reduced by >50% the MGMT level at the concentration of 40 μM for Jurkat cells, whereas little or no effect was found when lower concentrations were used. Downregulation of MGMT expression is produced at 40 μM for HCT116 cells. Provoked an ~50% reduction of MGMT level at 40 μM in normal NAMNC, and HL-60 promyelocytic leukemia, HT-29 colon cancer cells except for melanoma M10 cells that showed no downregulation of the protein.

In Vivo

Orlistat (10 mg/kg/day) significantly improves lipid profile, increases antioxidant enzymes and expression of anti-inflammatory markers, and decreases the expression of the pro-inflammatory marker compared to the obese (OB) group^[2].

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

Animal Model:	Eighteen male rats of Sprague–Dawley strain aged between 8–10 weeks weighing 200-250 g^[2]
Dosage:	10 mg/kg/day
Administration:	Orally; six weeks
Result:	Treatment persistently restored the increased body weight, which was significantly observed at the ninth week until the end of the experimental period.

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 (5.04 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 (5.04 mM); Suspended solution; Need ultrasonic

This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
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.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (5.04 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.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Method for preparing stock solution: mg drug dissolved in μL DMSO (Stock solution concentration: mg/mL).

The concentration of the stock solution you require exceeds the measured solubility. The following solution is for reference only. If necessary, please contact MedChemExpress (MCE).

Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.

If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.

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.
