| Targets |
Ethyl linoleate targets multiple pathways and enzymes. It inhibits the Akt/GSK3β/β-catenin signaling pathway and blocks NF-κB activation. It induces heme oxygenase-1 (HO-1) and inhibits tyrosinase. These activities contribute to its anti-inflammatory, whitening, and anti-atherosclerotic effects. It also promotes compound absorption.
|
|---|---|
| ln Vitro |
In vitro, ethyl linoleate (400 µM; 48 h) significantly inhibits melanin content and intracellular tyrosinase activity in α-MSH-induced B16F10 cells. It (1-20 µM; 1-24 h) attenuates lipopolysaccharide-induced pro-inflammatory cytokine production by inducing HO-1 in RAW264.7 cells. It inhibits the development of atherosclerotic lesions and the expression of inflammatory mediators.
|
| ln Vivo |
In vivo, ethyl linoleate (10% added to a high-cholesterol diet; p.o.; 12 weeks) has a significant effect on atherosclerosis induced by a high-cholesterol diet in rabbits. It increased body weight, accelerated the increase of serum and liver cholesterol levels, caused fatty infiltration in the liver and spleen, but reduced atherosclerotic proliferation of the aorta and kidneys.
|
| Enzyme Assay |
In vitro assays for ethyl linoleate typically involve cell viability, melanin content, and tyrosinase activity assays. A standard protocol for melanogenesis inhibition involves culturing B16F10 melanoma cells and treating them with ethyl linoleate (typically 1-400 µM) for 48 hours. Melanin content is measured spectrophotometrically, and tyrosinase activity is assessed using L-DOPA as a substrate. For anti-inflammatory studies, RAW264.7 macrophages are treated with ethyl linoleate (1-20 µM) and stimulated with LPS, and cytokine production is measured by ELISA.
|
| Cell Assay |
In vitro cell culture experiments with ethyl linoleate typically involve B16F10 melanoma cells for melanogenesis studies or RAW264.7 macrophages for anti-inflammatory studies. Cells are cultured in appropriate media and treated with the compound at concentrations ranging from 1-400 µM for 24-48 hours. Cell viability is assessed using MTT assays. Melanin content, tyrosinase activity, and cytokine levels are measured.
|
| Animal Protocol |
In vivo animal studies with ethyl linoleate are conducted to study its effects on atherosclerosis. A typical protocol involves administering the compound orally to rabbits at a dose of 10% added to a high-cholesterol diet for 12 weeks. Serum and liver cholesterol levels, as well as atherosclerotic lesions in the aorta, are measured.
|
| ADME/Pharmacokinetics |
Ethyl linoleate is an orally active compound. Based on its physicochemical properties (molecular weight 308.50, soluble in DMSO at 100 mg/mL), it is expected to have good oral bioavailability. It is stored as a pure form at -20°C for up to 3 years.
|
| Toxicity/Toxicokinetics |
Ethyl linoleate is generally considered safe as a fatty acid ester. Standard laboratory safety precautions should be followed when handling this compound, including the use of gloves and safety glasses. It is not intended for drug, household, or other uses without further formulation and testing.

| Additional Infomation |
Ethyl linoleate is a long-chain fatty acid ethyl ester formed by the condensation of the carboxyl group of linoleic acid and the hydroxyl group of ethanol. It is a plant metabolite and anti-inflammatory agent, functionally related to linoleic acid. Ethyl linoleate has been reported to exist in daphne, corn, and other organisms with relevant data.
Ethyl linoleate is an orally active unsaturated fatty acid with whitening, anti-inflammatory, and anti-atherosclerotic effects. It inhibits the Akt/GSK3β/β-catenin signaling pathway and NF-κB activation. It is used in research on inflammatory diseases and can be used in cosmetics. It has not undergone clinical trials and is not approved as a pharmaceutical. |
