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
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].
Cell Research 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.
In Vivo
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].

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
