Product Description
Aurantiamide is an orally active component of Purslane and has a variety of biological activities, including antioxidant, antiplatelet, anti-inflammatory, and anti-tumor activities.
Aurantiamide (CAS 58115-31-4) is a naturally occurring dipeptide compound consisting of phenylalanine and leucine residues. It has the molecular formula C₂₅H₂₆N₂O₃ and a molecular weight of approximately 402.49 g/mol. Aurantiamide is found in various plant species, including Aurantii Fructus Immaturus (bitter orange) and other medicinal plants. The compound exhibits various biological activities including anti-inflammatory, immunomodulatory, antioxidant, and hepatoprotective effects. It is used as a reference standard for the identification and quantification of dipeptide compounds in plant extracts and for research purposes.
Biological Activity I Assay Protocols (From Reference)
Targets
Multiple targets including inflammatory mediators, immune cells, and antioxidant pathways. Aurantiamide exhibits anti-inflammatory activity by inhibiting the production of pro-inflammatory mediators such as NO, TNF-α, and IL-6. It may modulate immune cell function by affecting T cell and macrophage activity. The compound may also have antioxidant activity by scavenging free radicals and reducing oxidative stress. Its hepatoprotective effects are attributed to its anti-inflammatory and antioxidant activities. The compound's mechanism of action may involve modulation of NF-κB and other signaling pathways.
ln Vitro

The compound may show immunomodulatory effects by regulating T cell and macrophage function. Antioxidant activity has been observed, with the compound scavenging free radicals and reducing oxidative stress. Hepatoprotective effects have been reported, with the compound protecting against liver damage in various models. The compound's specific in vitro activities would depend on the concentrations tested and the assay systems used. Further studies are needed to fully characterize its activity profile.
ln Vivo
In vivo studies of aurantiamide have demonstrated its anti-inflammatory and hepatoprotective effects. The compound has been shown to reduce inflammation in animal models and protect against liver damage. Its immunomodulatory effects may be beneficial in autoimmune and inflammatory conditions. The compound's antioxidant activity suggests potential benefits in oxidative stress-related diseases. Further studies are needed to characterize its specific in vivo pharmacokinetic and pharmacodynamic properties.
Enzyme Assay
Non-cell-based assays for aurantiamide include anti-inflammatory assays measuring inhibition of COX-2, LOX, or cytokine production in enzyme assays. Antioxidant activity is assessed using DPPH, ABTS, or FRAP assays. Immunomodulatory activity can be assessed using lymphocyte proliferation assays or cytokine production assays. Standard analytical methods including HPLC, NMR, and mass spectrometry are used for compound characterization.
Cell Assay
Cell-based assays for aurantiamide use various cell lines to assess its biological activities. Macrophage cell lines (e.g., RAW 264.7) are stimulated with LPS and treated with the compound, and inflammatory mediators in culture supernatant are measured. For immunomodulatory studies, splenocytes or peripheral blood mononuclear cells are treated with the compound and proliferation or cytokine production is measured. For antioxidant studies, cells are exposed to oxidative stress inducers and treated with the compound, and intracellular ROS levels are measured. Hepatoprotective effects are assessed in hepatocyte cell lines.
Animal Protocol
In vivo studies of aurantiamide have been conducted in animal models. For anti-inflammatory studies, carrageenan-induced paw edema or LPS-induced sepsis models are used. For hepatoprotective studies, CCl₄- or APAP-induced liver injury models are used. The compound is administered orally, intraperitoneally, or intravenously. Relevant endpoints including inflammatory markers, liver enzymes, and histopathology are measured.
ADME/Pharmacokinetics
Pharmacokinetic data for aurantiamide are limited. As a dipeptide compound with a molecular weight of approximately 402.49 g/mol, it may be absorbed after oral administration. The compound may undergo hydrolysis by peptidases to release its constituent amino acids. It is soluble in organic solvents such as DMSO. It should be stored as a powder at -20°C for up to 3 years or in solvent at -80°C for 1 year.
Toxicity/Toxicokinetics
Specific toxicity data for aurantiamide are limited. As a naturally occurring dipeptide, it is generally considered to have low toxicity. However, comprehensive toxicological studies have not been reported. Standard laboratory safety practices should be followed when handling this compound, including the use of personal protective equipment. It is intended for research use only.

  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
