Biological Activity
|
SIRT6 5.7 μM (EC50) |
IL-1β |
MDL-811 (0-100 μM; 48 h) inhibits the proliferation of multiple colorectal cancer cell lines (IC50: 4.7-61.0 μM) and induces cell cycle arrest[1].
MDL-811 (0-20 μM; 0-48 h) decreases the levels of H3K9Ac, H3K18Ac and H3K56Ac in a dose-dependent manner in colorectal cancer cell lines[1].
MDL-811 (0.1-5 μM; 4 h) inhibits LPS (HY-D1056)-induced TNF-α protein release and reduces the expression of inflammatory factors such as TNF-α and IL-1β in RAW264.7 macrophages[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:HCT116 cells
-
Concentration:0, 2.5, 5, 10 and 20 μM
-
Incubation Time:48 h
-
Result:Inhibited the levels of H3K9Ac, H3K18Ac and H3K56Ac.
MDL-811 (1-10 mg/kg; intravenous injection; 3 times) has improving effects in a mouse model of ischemic stroke[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Male BALB/c nude mice aged 6 weeks old treated HCT116 cells[1]
-
Dosage:20 and 30 mg/kg
-
Administration:Intraperitoneal injection; every other day; 16 days
-
Result:Significantly suppressed tumor growth in a dose-dependent manner, with reduced Ki67 staining and increased histone H3 deacetylation (H3K9Ac, H3K18Ac, H3K56Ac) in xenograft tissues.
-
Animal Model:Male ICR mice aged 8-10 weeks old (22-26 g) treated transient middle cerebral artery occlusion[2]
-
Dosage:1 and 10 mg/kg
-
Administration:Intravenous injection; 3 times: 1, 24 and 48 h after the surgery respectively
-
Result:Reduced infarct size and improved neurological deficits.
Reduced activated IBA1+CD16+ cells in the peri-infarct area.
Reduced pro-inflammatory gene expression (TNF-α, IL-1β) and enhanced anti-inflammatory gene expression (arginase1, CD206).

Solvent & Solubility
DMSO : 100 mg/mL (146.75 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 5 mg/mL (7.34 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.
Please enter the basic information of animal experiments:

Recommended: Prepare an additional quantity of animals to account for potential losses during experiments.
Please enter your animal formula composition:

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
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.
