A new series of coumarin carboxamide derivatives has been synthesized as probable acetylcholinesterase (AChE) inhibitors against alzheimer′s disease.The physicochem. parameters, drug-like properties of all compounds were assessed followed by mol. docking and mol. dynamics simulation (MDS) targeting the active site of AChE (PDB ID: 1EVE).The unique chem. structure of coumarin derivatives allows them to form strong hydrogen bonds, π-π interactions, or hydrophobic interactions, which disrupt AChE′s normal function and prevent the breakdown of acetylcholine.The compounds formed hydrogen bonds with amino acids residues Phe288(2.13 Å), Tyr70(2.02 Å), Tyr121(2.30 Å), Asp72(1.93 Å), Lys413(1.97 Å), Gln69(2.16 Å), Gln526(2.41 Å), and Arg289(1.83 Å).The higher binding affinities, especially compounds 3 and 10, with binding energies of -8.71 and -8.52 kcal/mol and predicted EC50 values of 1.09 x 10-7 and 9.12 x 10-8 resp., which were comparable to the reference drugs.Several parameters like RMSD, RMSF and RGyr of mol. dynamics simulation (MDS) were found satisfactory for the complexes formed by compounds 3 and 10 with the target protein and it showcased robust stability over 100 ns duration.The cytotoxicity screening also revealed that compounds 3 and 10 exhibited less toxicity against HEK293 cell lines.The higher stability of complexes formed by compounds 3 and 10 with AChE, lower predicted EC50 and cytotoxicity clearly endorsed that compounds 3 and 10 might act as potential inhibitors of AChE and can be taken forward to generate new potential candidates.
