KML29
Based on 3 publication(s) in Google Scholar
KML29 is an extremely selective, orally active and irreversible MAGL inhibitor, with IC50 values of 15 nM, 43 nM and 5.9 nM for mouse, rat and human MAGL, respectively. KML29 exhibits minimal cross-reactivity toward other central and peripheral serine hydrolases, including no detectable activity against FAAH.

Biological Activity
IC50: 15 nM (mouse MAGL), 43 nM (rat MAGL), 5.9 nM (human MAGL)[2].
KML29 dose-dependently elevates brain 2-AG level up to 10-fold without alteration in brain levels of anandamide, palmitoylethanolamide, and oleoylethanolamide[2].
KML29 is a potent inhibitor of 2-AG hydrolysis, but did not affect AEA hydrolysis at any concentration tested[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
KML29 (20 mg/kg) has a significant but modest protective effect against LPS-induced fever[3].

Animal Model:C57Bl/6 mice[2].
-
Dosage:1-40 mg/kg.
-
Administration:P.O. single dose.
-
Result:Selectively inhibited MAGL in mice.
-
Animal Model:Wistar albino male rats[2].
-
Dosage:20 mg/kg (+LPS E. coli O111:B4 (250 µg/kg, sc)).
-
Administration:SC.
-
Result:Administration of KML29 simultaneously with LPS E. coli O111:B4 significantly decreased ∆T (with 5% type 1 error, 1.7 fold) compared to saline+LPS E. coli O111:B4. Administration of KML29 simultaneously with LPS E. coli O111:B4 resulted in decreased plateau phase of fever compared to LPS E. E. coli O111:B4+saline administration.

Solvent & Solubility
DMSO : 50 mg/mL (91.01 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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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: ≥ 2.5 mg/mL (4.55 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.

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.
