(-)-Syringaresinol is an orally active isomer of syringaresinol (HY-N8307) found in Annona Montana. (-)-Syringaresinol exhibits antioxidant, anti-inflammatory, and anticancer activities. (-)-Syringaresinol can alleviate ulcerative colitis via the PI3K-Akt/MAPK/Wnt signaling pathway. (-)-Syringaresinol inhibits HL-60 cell proliferation by arresting the G1 phase and inducing apoptosis. (-)-Syringaresinol inhibits LPS (HY-D1056)-induced microglial activation by downregulating the NF-kappaB p65 signaling pathway and its interaction with ERbeta, exerting anti-neuroinflammatory effects[1][2][3].
