Product Description
Kadsuric acid is a triterpenoid compound that can be isolated from the fruit of Schisandra sphenanthera.
Kadsuric acid (CAS 62393-88-8) is a triterpenoid compound that can be isolated from the fruits of Schisandra sphenanthera and other plants including Kadsura coccinea and Piper kadsura [17L31-L33][17L23-L25]. It has the molecular formula C30H46O4 and a molecular weight of 470.68 g/mol [17L10-L11]. The compound appears as a powder with a purity of >98% and belongs to the class of terpenoids [17L23-L25]. The IUPAC name is (Z,6R)-6-[(3aR,6S,7S,9aS,9bS)-6-(2-carboxyethyl)-3a,6,9b-trimethyl-7-prop-1-en-2-yl-1,2,3,4,7,8,9,9a-octahydrocyclopenta[a]naphthalen-3-yl]-2-methylhept-2-enoic acid, indicating a complex polycyclic structure with two carboxylic acid groups [17L4-L8].
Biological Activity I Assay Protocols (From Reference)
Targets
Specific target information for Kadsuric acid is not provided in the search results. As a triterpenoid compound isolated from Schisandra species, it may possess biological activities commonly associated with this class of natural products, including hepatoprotective, anti-inflammatory, and antioxidant effects [17L35]. However, its precise molecular target has not been identified. Triterpenoids from Schisandra are known to modulate liver function and protect against chemical-induced liver injury.
ln Vitro
Specific in vitro activity data for Kadsuric acid is not provided in the search results. The compound is primarily used as an analytical reference standard for natural product research. As a triterpenoid, it may exhibit various biological activities including anti-inflammatory, hepatoprotective, or cytotoxic effects. However, no IC50 or EC50 values are reported. The compound has a purity of >98% and is stored as a powder [17L23-L25].
ln Vivo
Specific in vivo activity data for Kadsuric acid is not provided in the search results. The compound has not been reported to be administered in animal models for efficacy studies. It is used as a reference standard, not as a therapeutic agent. Its in vivo pharmacological profile remains uncharacterized.
Enzyme Assay
Not applicable. Kadsuric acid is not used in cell-free binding assays. It is a natural product reference standard used in analytical chemistry for quality control and natural product research. Its characterization involves standard analytical methods such as HPLC, NMR, and MS to confirm identity and purity, not biological binding studies. The compound is stored as a powder at -20degC.
Cell Assay
Not applicable. Kadsuric acid is not commonly tested in cell-based assays for biological activity. It is a natural product standard used primarily in analytical chemistry. If cytotoxicity studies were to be performed, a general protocol would involve treating cancer cell lines (e.g., HepG2, HeLa, MCF-7) with varying concentrations (1-100 uM) for 48-72 hours, followed by MTT or CellTiter-Glo assays. However, no such data is reported.
Animal Protocol
Not applicable. Kadsuric acid is not used in animal studies as a test article. It is a reference standard for analytical applications. Any in vivo studies would involve the quantification of this compound in biological samples (e.g., plant extracts, plasma) using the standard as a calibrator.
ADME/Pharmacokinetics
Specific pharmacokinetic data for Kadsuric acid is not available. As a triterpenoid with a molecular weight of 470.68 g/mol and two carboxylic acid groups, it is expected to have poor oral bioavailability due to low aqueous solubility and high molecular weight. Without such data, its absorption, distribution, metabolism, and excretion properties cannot be assessed.
Toxicity/Toxicokinetics
Specific toxicology data for Kadsuric acid is not provided. As a natural triterpenoid, it is presumed to have low toxicity at the concentrations used for analytical purposes. Standard laboratory safety precautions for handling organic compounds should be followed, including the use of gloves, lab coat, and safety goggles.
Additional Infomation
Reports indicate that safflower caldura contains caldura acid, and relevant data is available for reference.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • 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)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
