A series of caudatin derivatives were synthesized, and their anti-hepatitisBvirus (HBV) activity was evaluated in HepG 2.2.15 cells. Most of the 3-O-substituted caudatin derivatives showed effective anti-HBV activity. Among the tested compounds, six compounds (2e–2h, 2l, 2r) exhibited significantly inhibitory activity against HBV DNA replication with IC50 values in the range of 2.82–7.48 μM. Interestingly
The antifungalactivities of eleven C21-steroidal compounds isolated from Cynanchum wilfordii, together with thirty-six derivatives of caudatin and qingyangshengenin were evaluated on Sclerotinia sclerotiorum and other five fungal strains by the mycelium growth rate method. Four derivatives 1k, 1y, 10d, and 10j exhibited much stronger inhibitions on growth of S. sclerotiorum with IC50 values of 0.0084

Four Caudatin glycosides were synthesized from Caudatin by reaction with tetra-O-actyl-D-glycosyl bromide
catalyzed by CdCO3 and tested in vitro for their antiproliferative activities against human lung cancer A549, human
prostate cancer PC3, human liver cancer BEL-7402 and human gastric cancer SGC-7901 cells. The IC50 values indicated
that the inhibitory effect of Caudatin-tetra-O-actyl-D-glycosides was superior or comparable to Caudatin against most of
the tested cells, worthy of further investigation.
