• Non-phosphorus-based fructose-1,6-bisphosphatase (FBPase) inhibitors, 2,5-diphenyl-1,3,4-oxadiazoles, were explored.
• Compounds bearing a linear alkyl with terminal hydrogen-bonding acceptor showed potent inhibition at molecular level.
• Compound 22 and 27b inhibit the glucose production in primary rat hepatocytes with an IC50 value of 167.3 μM and 112.5 μM.
• Both inhibition and binding mode to the enzyme were investigated by enzymatic kinetics and in silico experiments.
With the aim of discovering a novel class of non-phosphorus-based fructose-1,6-bisphosphatase (FBPase) inhibitors, a series of 2,5-diphenyl-1,3,4-oxadiazoles were synthesized based on the hit compound (1) resulting from a high-throughput screening (HTS). Structure–activity relationship (SAR) studies led to the identification of several compounds with comparable inhibitory activities to AMP, the natural allosteric inhibitor of FBPase. Notably, compound 22 and 27b, bearing a terminal carboxyl or 1H-tetrazole, demonstrated remarkable inhibition to gluconeogenesis (GNG). In addition, both inhibition and binding mode to the enzyme were investigated by enzymatic kinetics and in silico experiments for representative compounds 16 and 22.
Novel non-phosphorus-based FBPase inhibitors were explored, and some compounds showed comparable inhibitory activities to AMP and remarkable inhibition to gluconeogenesis. Both inhibition and binding mode to the enzyme were investigated.Figure optionsDownload as PowerPoint slide
