BIOLOGICAL EVALUTION OF THIAZOLE DERIVATIVES BEARING DITHIOCARBAMATE MOIETY AS POTENTIAL CHOLINESTERASE INHIBITORS
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2015, Vol 7, Issue 2
Abstract
Objective: This study aimed to synthesize some thiazole derivatives bearing dithiocarbamic acid esters and to evaluate their anticholinesterase activity.Methods: 2-Chloro-N-[4-(2-methyl-4-thiazolyl)phenyl]acetamide was stirred with appropriate sodium salts of dithiocarbamic acids in acetone. The resulted compounds were elucidated using IR, 1H-NMR, and FAB+-MS spectral data. Each derivative was evaluated for its ability to inhibit acetyl cholinesterase (AChE) in vitro by using a modification of Ellman’s spectophotometric method.Results: Two of the synthesized compounds (6b,6c) can be identified as promising anticholinesterase agent due to their inhibitory effect on ACEH with IC50 value of86.34±1.31, 91.74±1.43 respectively when compared with standard substance Donepezil (IC50 =0.054±0.002μM) under the same experimental conditions.Conclusion: dimethylaminoethyl/propyl substitution on Piperazine residue have a crucial influence on anticholinesterase activity.Â
