Extensive SAR and Computational Studies of 3-{4-[(Benzylmethylamino)methyl]phenyl}-6,7-dimethoxy-2H-2-chromenone (AP2238) Derivatives
摘要:
AP2238 was the first compound published to bind both anionic sites of the human acetylcholinesterase, allowing the simultaneous inhibition of the catalytic and the amyloid-beta pro-aggregating activities of AChE. Here we attempted to derive a comprehensive structure-activity relationship picture for this molecule, affording 28 derivatives for which AChE and BChE inhibitory activities were evaluated. Selected compounds were also tested for their ability to prevent the AChE-induced A beta-aggregation. Moreover, docking simulations and molecular orbital calculations were performed.

A straightforward, regioselective, and step-economical ligand-free palladium-catalyzed decarboxylative functionalization of coumarin-3-carboxylic acids is devised. This protocol is compatible with a wide variety of electron-donating and -withdrawing substituents and allows for construction of various biologically important π-electron extended coumarins.
