Synthesis of indolyl linked benzylidene based meta‐substituted phenyl containing thiazolidinediones (4a–b), rhodanine (5a–b), and 1,3‐dicarbonyl based acyclic analogs of isoxazolidinediones (6a–7b) in an effort to develop novel α‐glucosidase inhibitors in the management of hyperglycemia for the treatment of type 2 diabetes is reported. The structure of all the novel synthesized compounds was confirmed through the spectral studies (LC–MS, 1H‐NMR, 13C‐NMR, and FTIR). Comparative evaluation of these compounds revealed that the compound 5b showed maximum inhibitory potential against α‐amylase and α‐glucosidase giving an IC50 value of 0.28 ± 0.01 μM. Furthermore, binding affinities in terms of G score values and hydrogen bond interactions between all the synthesized compounds and the AA residues in the active site of the protein (PDB code: 3TOP) to that of Acarbose (standard drug) were explored with the help of molecular docking studies. Compound 5b was considered as promising candidate of this series.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
