Biological Activity
| ln Vitro | Autophagy is enhanced by chelagic acid. Chebulic acid possesses anti-infective and anti-inflammatory properties. Similar to the clinical symptoms of Parkinson's disease, 1-methyl-4-phenylpyridinium (MPP+)-induced cytotoxicity is another condition against which chelagic acid shows preventive properties. Chebulagic acid suppresses the elevation of TNF-α and IL-1β generated by LPS in a way that is dependent on both dose and time. Additionally, in EA.hy926 cells, chemilagic acid therapy reduced LPS-activated MAPK signaling. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~100 mg/mL (~104.75 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 0.83 mg/mL (0.87 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 8.3 mg/mL clear DMSO stock solution to 400 μL of PEG300 and mix evenly; then add 50 μL of Tween-80 to the above solution and mix evenly; then add 450 μL of 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: ≥ 0.83 mg/mL (0.87 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in 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 8.3 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: ≥ 0.83 mg/mL (0.87 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 8.3 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.) |
