Biological Activity
| ln Vitro | In primary macrophages, JC-171 (0-100 μM) dose-dependently inhibits the activation of the NLRP3 inflammasome and the generation of IL-1β [1]. |
| ln Vivo | JC-171 therapy delays the course and lowers the severity of experimental autoimmune encephalomyelitis (EAE) in mice [1]. |
| Cell Assay |
Cell viability assay[1] Cell Types: J774A.1 mouse macrophage Tested Concentrations: 0-100 μM. Incubation Duration: 0.5 hrs (hours) (4.5 hrs (hours) before LPS (1 μg/mL) treatment). Experimental Results: Inhibited the release of IL-1β in J774A.1 cells after LPS/ATP stimulation. |
| Animal Protocol |
Animal/Disease Models: On day 0, mice were immunized subcutaneously (sc) (sc) with 200 μg of myelin oligodendrocyte glycoprotein (MOG) 35-55 peptide emulsified in Freund's complete adjuvant (CFA), followed by injection of 200 ng of pertussis toxin . Doses: 100 mg/kg, 10 mg/kg. Route of Administration: IP on days 0, 1, and 2; every other day thereafter (100 mg/kg). Dosing (10 mg/kg) was started every other day starting when an individual mouse's clinical score reached 1 (flaggy tail). Experimental Results: Compared with vehicle treatment, EAE progression was effectively inhibited. Resulting in a substantial decrease in the frequency of MOG35-55-specific Th17 cells in the spleen and spinal cord of EAE mice. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~250 mg/mL (~649.64 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (5.40 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (5.40 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
