Sulfosuccinimidyl oleate sodium (Synonyms: SSO)

Sulfosuccinimidyl oleate sodium is a long chain fatty acid that inhibits fatty acid transport into cells. Sulfosuccinimidyl oleate binds the CD36 receptor on the surface of microglia. Anti-inflammatory effect[1].

Sulfosuccinimidyl oleate (20 μM and 50 μM, 24 hours) alone does not alter the cellular viability. Exposure to 100 ng/ml LPS+5 ng/mL IFNγ modestly, yet significantly reduces the viability of the BV2 cells. Co-treatment with Sulfosuccinimidyl oleate prevents the LPS+IFNγ-induced reduction in the cell viability[1]. Sulfosuccinimidyl oleate (50 μM, 24 hours) co-treatment significantly reduces the LPS+IFNγ-induced expression of NOS2 and COX-2 in BV2 cells. Western blot analysis reveals a significant LPS/IFNγ-induced upregulation in the phosphorylated form of the p38, which is prevented by co-treatment with Sulfosuccinimidyl oleate (50 μM, 24 hours)[1]. Cell Viability Assay[1] Cell Line: BV2 cells

Sulfosuccinimidyl oleate (50 mg/kg; administered once by single oral gavage) significantly reduces the cortical ischemic infarct size compared to vehicle-treated controls in male BALB/cABom mice with pMCAo model. In addition, Sulfosuccinimidyl oleate at 50 mg/kg is suitable to see a beneficial effect after stroke[1]. Animal Model: 4-month-old male BALB/cABom mice with pMCAo model[1]
