The study synthesized a series of potential aldose reductase inhibitors, among which compound 3n showed the highest potential, with high selectivity and affinity.
The over expression of aldose reductase (ALR2) in the state of hyperglycemia causes the conversion of glucose into sorbitol and initiates polyol pathway. Accumulation of sorbitol in insulin insensitive tissue like peripheral nerves, glomerulus and eyes, induces diabetic complications like neuropathy, nephropathy and retinopathy. For the treatment of diabetic complications, the inhibition of aldose reductase (ALR2) is a promising approach. A series of coumarin-based thiosemicarbazone derivatives was synthesized as potential inhibitor of aldose reductase. Compound N-(2-fluorophenyl)-2-(1-(2-oxo-2H-chromen-3-yl)ethylidene)hydrazinecarbiothioamide (3n) was found to be the most promising inhibitor of ALR2 with an IC50 in micromolar range (2.07 mu M) and high selectivity, relative to ALR1. The crystal structure of ALR2 complexed with 3n explored the types of interaction pattern which further demonstrated its high affinity. Compound 3n has excellent lead-likeness, underlined by its physicochemical parameters, and can be considered as a likely prospect for further structural optimization to get a drugable molecule.
