(-)-Syringaresinol

(-)-Syringaresinol, is the isoform of Syringaresinol (HY-N8307), which can be found in stems of Annona Montana, possesses anti-cancer activity. Syringaresinol is an activator of NO synthase phosphorylation and induces vasodilation. Syringaresinol also inhibits the NF-κB pathway and exerts anti-inflammatory activity[1][2][3].

ChEBI: (-)-syringaresinol is the (7beta,7'beta,8beta,8'beta)-stereoisomer of syringaresinol. It is an enantiomer of a (+)-syringaresinol.
