Various physicochemical and spectroscopic techniques, including FT-IR, 1H and magnetic susceptibility, mass spectrometry, TGA, and others, were used to precisely characterize the synthesized compounds. These techniques suggested that the complexes' octahedral geometry was formed by epoxy oxygen atoms, azomethine nitrogen atomsof the dioxatetraaza ligand, and oxygen from the water molecules. The compounds' in vitro antibacterial activity against two bacterial and fungal pathogens was evaluated using the serial dilution method. Theoretical molecular docking was used to confirm these findings.","PeriodicalId":11498,"journal":{"name":"Egyptian Journal of Chemistry","volume":"390 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139019671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structural elucidation of these newly created compounds was achieved through a combination of analytical techniques, including IR, 1 H NMR, and 13 C NMR. We then evaluated the inhibitory activity of these compounds against acetylcholinesterase (AChE) using the Ellman's method spectrophotometer, comparing their performance to standard drugs like donepezil, rivastigmine, and tacrine. Impressively, the majority of the tested compounds demonstrated inhibitory activity against AChE, with iminothiazolidinone derivative (5a) standing out as the most potent (IC 50 = 0.209 μ g/mL). It even surpassed the effectiveness of rivastigmine and tacrine, coming close to the potency of donepezil. Further investigation into the potential of these compounds as AChE inhibitors for Alzheimer's disease drug development involved docking simulations using Molecular Operating Environment (MOE). Derivatives 3,5-disubstituted-(2,3,4,6-tetra-o-acetyl-β -D- glucopyranosyl) imino) thiazolidin-4-ones (5a), (5f), (6c) and 3,5-disubstituted-( β -D-glucopyranosyl)imino)thiazolidin-4-one (6d) displayed promising docking scores in MOE simulations.
