in vitro antitumor activities against Bel7404 and SMMC7721 tumor cell lines. Compounds 5j and 6 exhibited more potent antitumor activity than positive control SA and DOX. CONCLUSION Structural modification of SA could lead to the discovery of potent anti-HCV or antitumor agents. Compounds 5h, 5j and 6 were promising lead compounds for development of novel HCV entry inhibition or antitumor agents.
