Abstract

With the aim of discovering a novel class of fructose-1,6-bisphosphatase (FBPase) inhibitors, a series of compounds based on tricyclic scaffolds was synthesized. Extensive SAR studies led to the finding of 8l with an IC50 value of 0.013 microM against human FBPase. An X-ray crystallographic study revealed that 8l bound at AMP binding sites of human liver FBPase with hydrogen bonding interactions similar to AMP.
