Abstract
A new series of oxopyrrolidines was synthesized and evaluated for their effect on Alzheimer's disease by measuring their inhibitory activity against acetyl cholinesterase enzyme and amyloid β 42 protein. Most of the compounds showed good inhibitory activity with ethyl 2-(2-(2, 6-dimethylphenylcarbamoyl)- 5-oxopyrrolidin-1-yl) acetate (V) having the highest activity against acetyl cholinesterase with IC50 value 1.84 ng/g tissue compared to standard donepezil 3.34 ng/g tissue. Furthermore, compound 1-((4-(4-chlorophenyl) piperazin-1-yl) methyl)-N-(2,6-dimethylphenyl)-5- oxopyrrolidine- 2-carboxamide (IIIe) displayed the highest activity against β 42 protein with IC50 value of 11.3 Pg/g tissue compared to 18.4 Pg/g tissue of donepezil.
