Description

γ-Linolenic Acid methyl ester (Methyl GLA) is an esterified version of γ-Linolenic Acid (GLA), which is an ω-6 fatty acid, serves as melanoma cell proliferation inhibitors. γ-Linolenic Acid methyl ester inhibits ADP-induced blood platelet aggregation and induces apoptosis[1][2][3][4][5].

In Vitro

γ-Linolenic Acid methyl ester (1-4 μg/mL; 72 h) induces apoptosis in vitro A-549 lung cancer cell lines using SRB assay. However GLA is due to its action at the gene/oncogene level and by altering BCl-2 expression[1].

Apoptosis Analysis[1]

Cell Line: A-549 lung cancer cell line
Concentration: 1, 2, 3, and 4 μg/mL
Incubation Time: 72 hours; observed at 24 h, 48 h, and 72 h
Result: Showed cytotoxicity potentially due to the induction of apoptosis of tumor cells by augmenting free radical generation only in the tumor cells but not normal cells.
In Vivo

γ-Linolenic Acid methyl ester decreases the hepatic triglycerides and histological evidence of fatty liver induced by EtOH[2].
γ-Linolenic Acid methyl ester could significantly decrease levels of plasma total cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C), MDA, atherosclerosis index (AI) and liver TC, MDA, and increase levels of high density lipoprotein cholesterol (HDL-C) in both normal and hyperlipidemic rats[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Hepatic pathol rats model induced by EtOH (male Sprague-Dawley rats, 250-300 g)[2]
Dosage: 90 mL, 50-60 mL
Administration: Intraperitoneal injection; once daily; administrated 90 mL during day 1-5 and day 9, 50-60 mL during day 6-8
Result: Decreased the hepatic triglycerides of 25.6 mg/g compared with saline (40.2 mg/g) or olive oil (42.8 mg/g) treatment.
Decreased liver index (the ratio of liver weight and body wight) in hyperlipidemic rats, but had no significant effect in normal rats.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (8.55 mM); Suspended solution

    This protocol yields a suspended solution of ≥ 2.5 mg/mL (saturation unknown). Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
