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

Cell Research:[1]
+ Expand
  • 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.

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
