Microwave-assisted synthesis of 2(1H)-pyridones and their glucosides as cell proliferation inhibitors

Nucleosides Nucleotides Nucleic Acids. 2011 Feb;30(2):120-34. doi: 10.1080/15257770.2010.551646.

Abstract

A new series of substituted 2(1H)-pyridones (4a-i) and their glucosides (5, 6a-e) were prepared as potential agents against leukemia (HL-60) cells. Glucosides (5,6a-e) were synthesized using three independent methods. Microwave protocol as an ecologically new method was used to synthesize the target compounds. Structures of the new products were confirmed using one- and two-dimensional NMR spectroscopy. In vitro exposure of pyridones substituted at position 4 with a 2-thienyl or 2-(trifluoromethyl)phenyl were found to exhibit high antiproliferation activities; in particular, 3-cyano-4-(thien-2'-yl)-6-(4''-chlorophenyl)-2(1H)-pyridone (4c) and its glucoside analogue (6c) had the highest activity.
