Based on 3 publication(s) in Google Scholar
LY2183240 is a highly potent blocker of anandamide uptake (IC50= 270 pM; Ki=540 nM). LY2183240 is a potent, covalent inhibitor of the endocannabinoid-degrading enzyme fatty acid amide hydrolase (FAAH) with an IC50 of 12.4 nM. LY2183240 inactivates FAAH by carbamylation of the enzyme's serine nucleophile. LY2183240 also inhibits several other brain serine hydrolases with IC50s of 5.3, 0.09, 8.2 nM for MAG lipase, bh6 and KIAA1363, respectively .

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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (8.13 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 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.
