Biological Activity

Description Atractylenolide I is the major sesquiterpenoid of the rhizome of A. macrocephala and shows a wide spectrum of pharmacological activities such as antiinflammatory, digestion promoting, and antioxidant effects.
In vitro Atractylenolide I decreases the TNF-α level in LPS-stimulated peritoneal macrophages in a dosedependent manner, IC50=23.1 μM. It also inhibits NO production in LPS-activated peritoneal macrophages, IC50=41 μM. The IC50 of Atractylenolide I for inhibiting the activity of iNOS is 67.3 μM. It shows no marked effects against 5-lipoxygenase (5-LOX) and cyclooxygenase (COX). Atractylenolide I is also reported previously to act on white blood cell membranes and TLR4 and its antiinflammatory activity is related to antagonizing TLR4 [1].
In vivo Atractylenolide I has anti-inflammatory effects. The treatment of Atractylenolide I significantly attenuates LPS-induced lung wet-to-dry weight ratio and MPO activity in LPS-induced acute lung injury mouse. It also significantly inhibits the production of TNF-α, IL-6, IL-1β, IL-13, and MIF production in bronchoalveolar lavage fluid (BALF), as well as neutrophils and macrophages in BALF, upregulates the production of IL-10 in BALF. Atractylenolide I protects mice acute lung injury induced by LPS via inhibition of TLR4 expression and NF-κB activation[2].

Protocol (from reference)

Cell Assay:[1]
  • Cell lines

    peritoneal macrophages

  • Concentrations

    1-1000 μM

  • Incubation Time

    24 h

  • Method

    2 × 104 cells per well are plated into 96-well plates, cells/well to a final volume of 200 μL, incubated at 37 °C for 24 h, and given a fresh change of medium. The cells are treated with atractylenolide I (1-1000 μM) dissolved in DMSO, and with LPS (final concentration 10 μg/mL) alone or in combination with atractylenolide I (1–100 μM) dissolved in DMSO. This DMSO percentage allows the optimal solubilization of atractylenolide I in aqueous solution. The control and LPS wells receive the same amount of DMSO. After 24 h of incubation at 37 °C, 20 μL of MTT (5 mg/mL) is added to each well and 4 h later the cells are lysed with 150 μL DMSO. The plate is shaken for 10 min and 30 min later the optical densities (OD570) for atractylenolide I are compared with the OD of the control or LPS stimulated wells to assess the cytotoxicity.

Animal Study:[2]
  • Animal Models

    LPS-induced acute lung injury mouse

  • Dosages

    5, 10 and 20 mg/kg

  • Administration
