Biochem/physiol Actions

Potent TLR2 and TLR4 antagonist that exhibits anti-inflammatory and anti-viral (anti-HIV) properties
Sparstolonin B (SsnB) is a polyphenol. It has a structural features similar to xanthone and isocoumarin. SsnB exerts anti-inflammatory properties on mouse and human macrophages. SsnB can significantly reduce hypoxia–reoxygenation-induced inflammation of cardiomyocytes by blocking extracellular signal-regulated protein kinase (ERK1/2) and c-jun N-terminal kinases (JNK) signaling pathways. Thus, SsnB acts as a potent therapeutic for the treatment of myocardial ischemia–reperfusion (MIR) injury.
Sparstolonin B (SsnB), an isocoumarin isolated from Sparganium stoloniferum and Scirpus yagara, is a potent TLR2 and TLR4 antagonist that exhibits anti-inflammatory and anti-viral (anti-HIV) properties. Sparstolonin B inhibits LPS induced inflammation in 3T3- L1 adipocytes, and reduces the body weight of rats fed with high fat diet. Sparstolonin B mitigates inflammation in nonalcoholic steatohepatitis (NASH) in mice model.
