Abstract

An efficient one-pot reaction for the synthesis of oxoaporphine Alkaloids has been developed. Twenty-three compounds of oxoaporphine Alkaloids were prepared and assessed for their antitumor activities. Most compounds inhibited the growth of T-24 tumor cells in vitro. Particularly, 4B displayed the most potent activity with an IC50 value of 0.5 μM, which was 19-fold more potent than the parent compound 4. The substitution at C3-position of oxoaporphine core by -NO2 significantly enhanced the Anticancer activity. Mechanism studies indicated that 4 and 4B induced cell cycle arrest at G2/M phase; in contrast, 4V induced cell cycle arrest at the S phase. Increase of mitochondrial ROS/CA2+ and decrease of MMP, accompanied by activation of Caspase-3/9, were observed in T-24 cells after exposure to compounds 4, 4B and 4V, suggesting that the mitochondrial pathway was involved in the induced Apoptosis. Moreover, compound 4B effectively inhibited tumor growth in a mouse xenograft model bearing T-24.
