During our research using a high-throughput screening system for discovery of a new class of human liver glycogen phosphorylase a (hLGPa) inhibitors, a series of 3-(3,4-dichlorophenyl)acrylamide derivatives were synthesized, and their inhibitory activities toward hLGPa were evaluated. Among the derivatives, (2E,2'E)-N,N'-pentane-1,5-diylbis[3-(3,4-dichlorophenyl)acrylamide] (6c) inhibited hLGPa with an IC50 value of 0.023 mu M. An X-ray crystallographic study of the enzyme-6c complex showed that the inhibitor is bound at the dimer interface site, where the 3,4-dichlorophenyl moiety interacts hydrophobically with the enzyme.
