Abstract

A series of thirty (30) thiazole analogs were prepared, characterized by (1)H NMR, (13)C NMR and EI-MS and evaluated for Acetylcholinesterase and butyrylcholinesterase inhibitory potential. All analogs exhibited varied butyrylcholinesterase inhibitory activity with IC50 value ranging between 1.59±0.01 and 389.25±1.75μM when compared with the standard eserine (IC50, 0.85±0.0001μM). Analogs 15, 7, 12, 9, 14, 1, 30 with IC50 values 1.59±0.01, 1.77±0.01, 6.21±0.01, 7.56±0.01, 8.46±0.01, 14.81±0.32 and 16.54±0.21μM respectively showed excellent inhibitory potential. Seven analogs 15, 20, 19, 24, 28, 30 and 25 exhibited good acetylcholinesterase inhibitory potential with IC50 values 21.3±0.50, 35.3±0.64, 36.6±0.70, 44.81±0.81, 46.36±0.84, 48.2±0.06 and 48.72±0.91μM respectively. All other analogs also exhibited well to moderate enzyme inhibition. The binding mode of these compounds was confirmed through molecular docking.
