Product Description
Methyl 2,6-dihydroxybenzoate is a volatile substance extracted from the whole flowers and corollas of Primula spectabilis.
Methyl 2,6-dihydroxybenzoate (CAS#: 2150-45-0), also known as γ-resorcylic acid methyl ester or 2,6-dihydroxybenzoic acid methyl ester, is a natural phenolic compound and a benzoic acid ester. It is functionally related to salicylic acid and has been found in the Guiana carapax (Carapa guianensis). The compound has the molecular formula C8H8O4 and a molecular weight of 168.15. It is a natural benzoate ester suitable for biochemical experiments and drug synthesis research.
Biological Activity I Assay Protocols (From Reference)
Targets
Methyl 2,6-dihydroxybenzoate does not have a well-defined pharmacological target. As a phenolic compound structurally related to salicylic acid, it may exhibit anti-inflammatory, antioxidant, or antimicrobial activities. It may interact with cyclooxygenase (COX) enzymes or other targets involved in inflammatory pathways, but specific binding affinities or mechanisms have not been extensively characterized. Its primary utility is as a research chemical and synthetic intermediate.
ln Vitro
In vitro, methyl 2,6-dihydroxybenzoate may exhibit antioxidant activity due to its phenolic hydroxyl groups, which can scavenge free radicals. It may also show anti-inflammatory activity by inhibiting COX enzymes or other inflammatory mediators. However, quantitative in vitro data (e.g., IC50 values) for this specific compound are not readily available from publicly accessible sources. The compound is primarily used as a research chemical and synthetic intermediate.
ln Vivo
Methyl 2,6-dihydroxybenzoate has no reported in vivo pharmacological activity. As a natural product, it may have been used in traditional medicine contexts, but modern pharmacological studies are limited. The compound is not used as a therapeutic agent and has no approved clinical indications. Its primary value is in biochemical research and as a starting material for drug synthesis.
Enzyme Assay
In vitro enzyme assays for methyl 2,6-dihydroxybenzoate would typically involve measuring its antioxidant activity using DPPH or ABTS radical scavenging assays. Anti-inflammatory activity could be assessed using COX-1 or COX-2 inhibition assays, where the compound is incubated with the enzyme and a substrate (e.g., arachidonic acid), and the production of prostaglandins is measured. Binding to other targets such as lipoxygenases or NF-κB could also be assessed using standard biochemical assays.
Cell Assay
In vitro cell-based assays for methyl 2,6-dihydroxybenzoate would involve culturing appropriate cell lines (e.g., macrophages, cancer cells) and treating them with the compound to assess effects on cell viability, inflammation, or oxidative stress. Cytotoxicity would be evaluated using MTT or LDH release assays. Anti-inflammatory activity could be assessed by measuring cytokine production (e.g., TNF-α, IL-6) in lipopolysaccharide-stimulated macrophages. Antioxidant activity could be assessed by measuring reactive oxygen species (ROS) levels using fluorescent probes.
Animal Protocol
In vivo animal studies for methyl 2,6-dihydroxybenzoate have not been reported in the literature. If conducted, such studies might involve oral or intraperitoneal administration in rodents to assess anti-inflammatory, analgesic, or antioxidant activities. Standard models for evaluating these activities include carrageenan-induced paw edema for anti-inflammatory effects, acetic acid-induced writhing for analgesic effects, and oxidative stress models for antioxidant effects. No specific data are available.
ADME/Pharmacokinetics
The pharmacokinetic properties of methyl 2,6-dihydroxybenzoate have not been characterized. As a small molecule with a molecular weight of 168.15 and multiple hydroxyl groups, it is expected to have moderate aqueous solubility. The compound may be absorbed orally and undergo first-pass metabolism, including hydrolysis of the ester group to yield 2,6-dihydroxybenzoic acid. Metabolism would likely occur via glucuronidation and sulfation of the phenolic hydroxyl groups. No specific PK data are available.
Toxicity/Toxicokinetics
The toxicity profile of methyl 2,6-dihydroxybenzoate has not been systematically evaluated. As a phenolic compound, it may cause skin or eye irritation upon contact. At high doses, phenolic compounds can be toxic and may cause liver or kidney damage. However, the compound's structural similarity to salicylic acid suggests that it may have a relatively favorable safety profile at low doses. Standard toxicology assessments would include acute, sub-chronic, and chronic toxicity studies in rodents. No specific toxicity data are available.

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)
