Abstract
Thiazole rings are one of the most frequently used heterocyclic moieties and are found in a wide variety of biologically active chemicals. In this research project, we report the synthesis and biological activities of some new thiazole derivatives (2a-2c) as potent anti-Alzheimer’s agents. These final compounds’ structures were characterized by spectral (1H NMR, 13C NMR, and MS spectra) analyses. The highest inhibitory activity against AChE was demonstrated by compound 2c (23.73 ± 0.018 %) with chloro substitution at the meta and para positions of the phenyl ring, while the highest inhibitory activity against BuChE was produced by compound 2a (28.87± 0.003 %) with cyano substitution at the f position of the phenyl ring. Ferrous ion-chelating and DPPH techniques were also used to assess the compounds' antioxidant properties. Compound 2a showed antioxidant effect according to the DPPH method with an IC50 value of 27.18 ± 0.009 µM.
