•Multicomponent synthesis of densely substituted paraconic acid analogs.•In vitro cytotoxicity evaluation of the compounds in human cancer cell lines.•Sub-micromolar activity of one of the tested compounds.•Determination of the mode of action using flow cytometry.•Activation of the apoptotic cascade without prominent blockade of the cell cycle.
Various 2,3-substituted γ-butyrolactones have been synthesized by three-component reaction of aryl bromides, dimethyl itaconate and carbonyl compounds. The in vitro cytotoxic activity of these products was evaluated against a representative panel of cancer cell lines (KB, HCT116, MCF7, MCF7R, PC3, SK-OV3, HL60 and HL60R). One compound (4x) displays a good anti-proliferative activity with IC50 in the sub-micromolar range. The mechanism of action has been investigated using flow cytometry.
