In this work, 23 new amides (14-36) bearing a representative diterpenoid structure unit, the functionalized bicyclo[3.2.1]octane ring, have been synthesized and its antitumor potential is studied. In vitro studies demonstrate that a number of amides with the bicyclo[3.2.1]oct-3-en-2-one subunit are active against HL-60, SMMC-7721, A-549, SK-BR-3, and PANC-1 tumor cell lines. The hybrid derivative, compound 20, was found to be the most potent compound (IC50 = 1.05 μM against HL-60) and more active than cisplatin (DDP), the positive control. Additionally, compound 20 exhibited broad spectrum in vitro anticancer activity with IC50 values of 1.1-4.3 μM against the five tested cancer cell lines.
