In the present study, 2-aryliminothiazolidin-4-ones (3 and 5) were utilized as dynamic chemical systems, whose different states are modulated in a reversible fashion through specific chemical stimuli. The in-depth NMR investigation revealed that the magnitude of rotational energy barrier (ΔG?) is affected markedly by (1) the solvent polarity; (2) the electronic nature of the ring system present on the exocyclic CQN bond and (3) the temperature of the system. The derivatives of 5-(3-arylallylidene)-2-(arylimino)thiazolidin-4-one exist in two isomeric forms at room temperature in DMSO-d6: (2E,5Z,7E) ? (2Z,5Z,7E). The stereodynamics of the synthesized derivatives (5a-5t) has been investigated using variable temperature dynamic 1H-NMR (VT DNMR). The ΔG? values (≈15 kcal mol?1) estimated for the dynamic process depict a significant barrier between two forms in solution at ambient temperature. To go a step further, line shape analysis was also performed to get a clear understanding of the equilibration mechanism.

Protein tyrosine phosphatase 1B (PTP1B) is an important target for the treatment of diabetes. A series of thiazolidin-4-one derivatives 8–22 was designed, synthesized and investigated as PTP1B inhibitors. The new molecules inhibited PTP1B with IC50 values in the micromolar range. 5-(Furan-2-ylmethylene)-2-(4-nitrophenylimino)thiazolidin-4-one (17) exhibited potency with a competitive type of enzyme inhibition. structure–activity relationship studies revealed various structural facets important for the potency of these analogues. The findings revealed a requirement for a nitro group-including hydrophobic heteroaryl ring for PTP1B inhibition. Molecular docking studies afforded good correlation with experimental results. H-bonding and π–π interactions were responsible for optimal binding and effective stabilization of virtual protein-ligand complexes. Furthermore, in-silico pharmacokinetic properties of test compounds predicted their drug-like characteristics for potential oral use as antidiabetic agents.Additionally, a binding site model demonstrating crucial pharmacophoric characteristics influencing potency and binding affinity of inhibitors has been proposed, which can be employed in the design of future potential PTP1B inhibitors.
