Metal complexes of anthranilic acid derivatives that constitute a novel class of non-sugar-type alpha-glucosidase inhibitors were synthesized and assessed in vitro for inhibitory activity. All of the Ag(I) complexes (9-16) inhibited alpha-glucosidase at the nanomolar scale, while 3,5-dichloroanthranilic acid silver(I) (9) was the most potent (IC50=3.21 nmol/L). Analysis of the kinetics of enzyme inhibition indicated that the mechanism of the newly prepared silver complexes was noncompetitive. The structure-activity relationships were also analyzed, and they are discussed in this report. (C) 2016 Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.
