Atractylenolide I (40, 60, 80, 100, 120, 150 μM) must be dosed and timed to dramatically diminish the cell viability of human A375 melanoma cells after 24, 48 and 72 hours of therapy. Atractylenolide I (50 and 100 μM) stimulated A375 cells in a dose-dependent manner after 48 hours of treatment. Atractylenolide I (100 μM) dramatically lowered protein levels of phosphorylated JAK2 and STAT3 in A375 cells, while having no effect on total JAK2 and STAT3. In addition, Atractylenolide I suppresses the mRNA expression of STAT3-repressed genes, including Bcl-xL, MMP-2, and MMP-9[1]. Atractylodes I (up to 100 μM) is not harmful to normal cells. Atractylodes I (25, 50 μM) decreased Ox-LDL-induced TNF-α, IL-6, and NO generation in VSMC. Atractylenolide I (12.5, 25 or 50 μM) significantly lowered MCP-1 levels and prevented Ox-LDL-induced VSMC proliferation and migration. Atractylenolide I (25, 50 μM) suppresses severe staining of foam cells and considerably lowers buffer buildup. Atractylenolide I (50 μM) suppresses Ox-LDL-stimulated p38MAPK and NF-κB p65 expression in VSMC [3]. Atractylenolide I (1, 10, 100 μM) wakes TLR4 signaling through MyD88 in EOC cells to atrophy paclitaxel-induced VEGF and survivin production [4].

In mice experiencing chronic unpredictable rest during the day (CUMS), atractyloid I (5, 10, or 20 mg/kg, nuchal) reverses body weight loss. Atractyloid I decreases pro-inflammatory cytokine levels in the hippocampal region produced by CUMS, diminishes depression induced by CUMS, and raises the NLRP3 inflammasome in the mouse hippocampal region [2].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (10.86 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 25.0 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: ≥ 2.5 mg/mL (10.86 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 25.0 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. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (10.86 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
