A series of phenylpiperazine derivatives (3a-3q) were designed and synthesized. In vitro assays indicated that several phenylpiperazine derivatives had excellent antiproliferative properties against four Cancer cell lines including multidrug-resistant Cancer cell lines, with IC50 values in the low micromolar range. The average IC50 of the most active compound 3b is 0.024μM to the MCF-7 cell line. In addition, the mechanism of action of these new analogues was investigated by molecular docking studies, insulin-like growth factor 1-receptor (IGF-1R) kinase assay and Apoptosis induced assay. These studies confirmed that these new phenylpiperazine derivatives maintain their mechanisms of action by disrupting IGF-1R kinase.
