Product Description
Coumaran (2,3-Dihydrobenzofuran) is an (AChE) inhibitor found in L. camara. Coumaran can be used as a biopesticide.
Coumaran, also known as 2,3-Dihydrobenzofuran, is a natural product found in organisms such as Trigonella foenum-graecum. It has a molecular formula of C8H8O and a molecular weight of 120.15. It is an inhibitor of acetylcholinesterase (AChE) and exhibits notable antileishmanial activity. It can be used as a biopesticide and has immunomodulatory activity.
Biological Activity I Assay Protocols (From Reference)
Targets
Coumaran targets acetylcholinesterase (AChE), an enzyme that breaks down the neurotransmitter acetylcholine in the synaptic cleft. By inhibiting AChE, coumaran increases the concentration of acetylcholine, leading to prolonged cholinergic signaling. This mechanism is the basis for its potential insecticidal and antiparasitic activities.
ln Vitro
In vitro, coumaran is an AChE inhibitor. It exhibits notable antileishmanial activity and is active against promastigotes (IC50 = 1.042 μM). It may acquire antiparasitic capabilities through activation of macrophages and exert immunomodulatory activity.
ln Vivo
In vivo, coumaran can be used as a biopesticide. Its AChE inhibitory activity and antileishmanial effects suggest potential for treating parasitic infections. Its immunomodulatory activity may also have therapeutic implications. Further in vivo studies are needed to confirm its efficacy.
Enzyme Assay
Non-cellular assays for coumaran involve measuring its inhibition of acetylcholinesterase (AChE) activity. These assays typically use the Ellman's method, where the enzyme is incubated with a substrate (acetylthiocholine) and the compound. The production of thiocholine is measured spectrophotometrically, and the IC50 is determined.
Cell Assay
In vitro cellular assays for coumaran are conducted to study its antileishmanial activity. Leishmania promastigotes are cultured and treated with the compound, and parasite viability is assessed. Its effects on macrophages can be studied by measuring cytokine production and activation markers to assess its immunomodulatory activity.
Animal Protocol
In vivo animal experiments with coumaran could be conducted in models of leishmaniasis. Infected animals would be treated with the compound, and parasite load and immune responses would be assessed. Its use as a biopesticide would be evaluated in agricultural or insect models.
ADME/Pharmacokinetics
Coumaran has a molecular weight of 120.15. It is a liquid at room temperature and is soluble in organic solvents. Its pharmacokinetic properties are not well-characterized. The compound is typically stored at room temperature.
Toxicity/Toxicokinetics
Coumaran is considered to have low toxicity based on its use as a research compound and its natural occurrence. However, comprehensive toxicological data are not extensively published. The compound is intended for research use only and is not approved for human therapeutic use.

For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 37.5 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

*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.

  • 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
