Design, synthesis and docking study of novel coumarin ligands as potential selective acetylcholinesterase inhibitors

New coumaryl-thiazole derivatives with the acetamide moiety as a linker between the alkyl chains and/or the heterocycle nucleus were synthesized and in vitro tested as acetylcholinesterase (AChE) inhibitors. 2-(diethylamino)-N-(4-(2-oxo-2H-chromen-3-yl)thiazol-2-yl)acetamide (6c, IC50 value of 43 nM) was the best AChE inhibitor with a selectivity index of 4151.16 over BuChE. Kinetic study of AChE inhibition revealed that 6c was a mixed-type inhibitor. Moreover, the result of H4IIE hepatoma cell toxicity assay for 6c showed negligible cell death. Molecular docking studies were also carried out to clarify the inhibition mode of the more active compounds. Best pose of compound 6c is positioned into the active site with the coumarin ring wedged between the residues of the CAS and catalytic triad of AChE. In addition, the coumarin ring is anchored into the gorge of the enzyme by H-bond with Tyr130.

Design, synthesis, antioxidant and anticancer activity of new coumarin derivatives linked with thiazole, isoxazole or pyrazole moiety

Background: Three new series of coumarin derivatives 4a-e, 6a-d and 7a-d were synthesized and characterized by elemental analyses and spectral data including 2D NMR. All compounds 4a-e, 6a-d and 7a-d were evaluated for their in vitro antioxidant and antic

REACTION OF MERCAPTOACETIC ACID AND CHLOROACETYL CHLORIDE WITH BENZALAMINO THIAZOLYL COUMARINS

2-Aryl-3--4-thiazolidinones (III), have been synthesized by the reaction of Schiff's bases (II) derived from 3-(2-amino-4-thiazolyl)-2H-1-benzopyran-2-ones (I) with mercaptoacetic acid.The Schiff's bases on reaction with chloroacetyl chloride in the presence of triethylamine in dioxane gave chloroacetamido derivative (IV) instead of expected compound V.
