Fmoc-leucine
Based on 1 Customer Validation
Fmoc-Leucine (N-FMOC-leucine) is an anti-inflammatory agent that not only promotes extracellular Ca2+ influx but also facilitates intracellular Ca2+ release. Fmoc-Leucine is a selective ligand for PPARγ (Ki = 15 μM), exhibiting insulin-sensitizing effects but with weak fatogenic activity. Fmoc-Leucine exhibits unique self-assembly properties and can form transient gels, stable gels, or crystals/2D sheets through different pathways. Fmoc-Leucine can be used in the research of diabetes, colitis, and bladder cancer.

Fmoc-Leucine (1 mM, 24 h) significantly enhances the interaction between PPARγ and SRC-1 in RK13 cells[1].
Fmoc-Leucine (10 μM, 0-6 d) induces the expression of LPL and aP2 in 3T3-L1 cells, but its ability to accumulate lipids is significantly lower than that of Rosiglitazone (HY-17386)[1].
Fmoc-Leucine (0.1-2 mM) rapidly and continuously increases [Ca²⁺]i in MDCK and BFTC cells in a concentration-dependent manner with an EC50 in MDCK cells of 0.5 mM[3][4].
Fmoc-Leucine induces the release of Ca²⁺ from the endoplasmic reticulum and activated the influx of Ca²⁺ in BFTC bladder cancer cells[4].

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