Preparation, anticholinesterase activity, and docking study of new 2-butenediamide and oxalamide derivatives
摘要:
Several new oxalamide and 2-butenediamide derivatives have been designed, synthesized and evaluated as the acetyl- and butyryl-cholinesterase inhibitors for Alzheimer's disease. The enzyme inhibitory activity of the synthesized compounds was measured using Ellman's colorimetric method. It was revealed that compound 1a (N, N'-bis-(4-chloro-benzyl)-N, N'-diphenyl-oxalamide) showed maximum activity against BuChE with a half maximal inhibitory concentration (IC50) = 1.86 mu M and compound 2a (but-2-enedioic acid bis-[(4-chloro-benzyl)-phenyl-amide]) exhibited optimum AChE (IC50 = 1.51 mu M) inhibition with a high-selectivity index. To better understand the enzyme-inhibitor interaction of the most active compounds towards cholinesterase, molecular modelling studies were carried out. Docking simulations revealed that inhibitors 1a and 2a targeted both the catalytic active site and the peripheral anionic site of 1ACJ and 1P0I.

In this study, a total of 18 new benzamide/ nicotinamide/ cinnamamide derivative compounds were designed and synthesized for the first time (except B1 and B5) by conventional and microwave irradiation methods. The chemical structures of the synthesized compounds were characterized by 1H NMR, 13C NMR, and HRMS spectra. In vitro acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibition

Forty six new 1,4-epoxy-2-exo-aryl-and cis-2-aryl-4-hydroxytetrahydro-1-benzazepine derivatives were synthesized and fully characterized. All compounds were tested in vitro against both Trypanosoma cruzi and Leishmania chagasi parasites and also for cytotoxicity using Vero and THP-1 mammalian cell lines. Many of the evaluated compounds showed remarkable activity against the epimastigote and intracellular amastigote forms of T. cruzi, with IC50 values comparable with that of control drug nifurtimox, a nitrofuran derivative currently used in the treatment of Chagas' disease. Other derivatives were found to have good activity against L. chagasi promastigotes, with low toxicity against the mammalian cells, but neither of them was active on intracellular amastigotes of L. chagasi infecting THP-1 macrophages.
