PubMed Abstract: Liver fructose-1,6-bisphosphatase (FBPase) is a key enzyme in the gluconeogenesis pathway. Inhibiting FBPase activity represents a potential treatment for type 2 diabetes mellitus. A series of novel -arylsulfonyl-4-arylamino-indole-2-carboxamide derivatives have been disclosed as FBPase inhibitors. Through extensive structure-activity relationship investigations, a promising candidate molecule [sodium (7-chloro-4-((3-methoxyphenyl)amino)-1-methyl-1-indole-2-carbonyl] [(4-methoxyphenyl)sulfonyl)amide] has been identified with high inhibitory activity against human liver FBPase (IC, 0.029 ± 0.006 μM) and high selectivity relative to the other six AMP-binding enzymes. Importantly, 8 produced significant glucose-lowering effects on both type 2 diabetic KKAy mice and ZDF rats as demonstrated by substantial reductions in the fasting and postprandial blood glucose levels, as well as the HbA1c level. Furthermore, elicited a favorable pharmacokinetic profile with an oral bioavailability of 99.1%. Moreover, the X-ray crystal structure of the -FBPase complex was resolved, which revealed a unique binding mode and provided a structural basis for its high potency and selectivity.
