Abstract

A new class of polyamine analogues modified by alkylation at the terminal of the polyamine chain has been synthesized and their structures were determined by 1H NMR, 13C NMR, ESI-MS and elemental analysis. As the representative compound, 3f displayed a broad spectrum of anti-cancer effects by MTT assays. Tumor xenograft model and pulmonary metastasis model showed that compound 3f significantly suppressed tumor growth and metastasis in vivo, which was more stronger than the reference drug amonafide. Molecular mechanisms indicated that compound 3f exhibited antiproliferative activities and induced the generation of Reactive Oxygen Species (ROS), which resulted in the occurrence of Autophagy. The downregulated expression of MMP-9 and β-catenin by compound 3f accounted for the inhibition of migration. Taken altogether, the in vitro and in vivo biological evaluations corroborated compound 3f to be an effective Anticancer agent.
