Description

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[1][2].

IC50 & Target

IC50: 15 nM (mouse MAGL), 43 nM (rat MAGL), 5.9 nM (human MAGL)[2].
In Vitro

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].

In Vivo

KML29 enhibits antinociceptive activity without cannabimimetic side effects[3].
KML29 (20 mg/kg) has a significant but modest protective effect against LPS-induced fever[3].

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

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.

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 (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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (4.55 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.

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.
