Sulfosuccinimidyl oleate sodium (Sulfo-N-succinimidyl oleate sodium) is a long-chain fatty acid that inhibits the transport of fatty acids to cells, acts as an effective irreversible inhibitor of the mitochondrial respiratory chain, and binds to CD36 receptors on the surface of microglia.

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].

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