Sparstolonin B acts as a selective TLR2 and TLR4 antagonist and selectively blocks TLR2- and TLR4-mediated inflammatory signaling. Sparstolonin B has anti-HIV and anticancer activities[1][2]. | [Biochem/physiol Actions]
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. | [in vivo]
