An efficient and easy procedure to synthesize the pyridinyl analogues of dibenzylideneacetone (pyr-dba) was developed by the condensation of substituted nicotinaldehyde and acetone in the presence of K2CO3 in toluene-EtOH-H2O solvent system. Structurally diverse pyr-dba, including quinolinyl dba, can be prepared conveniently in moderate to excellent yields under mild conditions with this method. The resulting pyr-dba functioned as the enone analogs of curcumin and efficiently inhibited the activation of NF-κB and the growth of colorectal carcinoma HCT116 p53+/+ cells as well as the HIV-1 IN-LEDGF/p75 interaction.
