| Targets |
Atractylenolide I targets multiple signaling pathways. It is a TLR4 antagonist. It reduces JAK2 and STAT3 phosphorylation. It regulates NF-κB and MAPK signaling pathways. It ameliorates sepsis syndrome by reducing pro-inflammatory cytokines and LPS.

| ln Vitro |
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 vitro, Atractylenolide I is a TLR4 antagonist. It reduces JAK2 and STAT3 phosphorylation in A375 cells. It regulates NF-κB and MAPK signaling pathways. It possesses neuroprotective, anti-allergic, anti-inflammatory, and anticancer properties. |
| ln Vivo |
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].
In vivo, Atractylenolide I ameliorates sepsis syndrome by reducing pro-inflammatory cytokines and LPS, and provides an improvement in liver and kidney functions. Its anti-inflammatory and immunomodulatory activities suggest potential in models of inflammatory diseases. Further in vivo studies are needed to fully characterize its therapeutic potential. |
| Enzyme Assay |
In vitro assays for Atractylenolide I are conducted to assess TLR4 antagonism, JAK2/STAT3 inhibition, and NF-κB/MAPK modulation. TLR4 activity is measured using reporter gene assays or by measuring cytokine production in TLR4-expressing cells. JAK2 and STAT3 phosphorylation is measured by Western blotting.
|
| Cell Assay |
Cellular assays for Atractylenolide I are performed using A375 melanoma cells or other cancer cell lines. Cells are treated with compound concentrations ranging from 0.1 to 100 µM for 24-72 hours. JAK2 and STAT3 phosphorylation is assessed by Western blotting. Cell viability is assessed using MTT or CCK-8 assays.
|
| Animal Protocol |
In vivo animal studies for Atractylenolide I have been conducted in sepsis models. Rodents are administered the compound orally or intraperitoneally. Endpoints include survival, serum cytokine levels, and liver and kidney function tests.
|
| ADME/Pharmacokinetics |
Pharmacokinetic properties of Atractylenolide I are not well characterized. The compound has a molecular weight of 230.30. It is a lipophilic sesquiterpene. Standard PK studies in rodents would be required to determine half-life, bioavailability, and tissue distribution.
|
| Toxicity/Toxicokinetics |
Toxicological data for Atractylenolide I are limited. As a natural product-derived compound, it may have a moderate safety profile. No significant acute toxicity has been reported. Standard toxicity screening would involve acute and repeated-dose studies in rodents.
