A green protocol for an effective synthesis of bioactive polyhydroquinoline derivatives was developed via condensation of substituted salicylaldehyde, dimedone, ethyl acetoacetate and ammonium acetate catalyzed by 3-methyl-1-sulfonic acid imidazolium chloride ([Msim]Cl) in excellent yield. All synthesized derivatives were evaluated for inhibition of cancer cells. The initial assays reveals that some of the synthesized derivatives show significantly satisfactory inhibition activities against human breast cancer cells (MCF7) compared with the control (Adriamycin), which might be developed as novel lead scaffold for potential anticancer agents.
