Saikosaponin B1

Saikosaponin B1 is a bioactive constituent of Radix Bupleuri. Saikosaponin B1 is an agonist of the 5-HT2C receptor with an EC50 of 147.41 μM. Saikosaponin B1 inhibits the Hedgehog (Hh) signaling pathway by targeting the transmembrane protein SMO. Sailosaponin B1 can reduce liver fibrosis. Saikosaponin B1 has anti-cancer activities thus can be studies in research for cancers such as Medulloblastoma (MB) [1][4].
