Quinoline/Thiazole Compounds as Selective Acetylcholinesterase Inhibitors: Synthesis and Biological Assessment

Abstract

Acetylcholine (ACh), acetylcholinesterase enzyme (AChE), and AChE inhibition are of great importance in the treatment of neurodegenerative diseases. When it comes to AChE inhibition, FDA-approved AChE inhibitors such as Donepezil are actively used in the treatment of neurodegenerative disorders. However, there is still a need for novel and unique inhibitors for the radical treatment of these diseases. The aim of this study was to design and evaluate new inhibitors for the treatment of neurodegenerative diseases. To meet this need, a series of new quinoline/thiazole derivative compounds were designed, synthesized, and their structures elucidated using 1 H-NMR, 13 C-NMR and HRMS. There are many studies showing that quinolines and thiazoles have high potential efficacy in AChE inhibition. The compounds were synthesized through a multistep synthetic route, and their inhibitory activities were subsequently examined using. These findings suggest that these novel quinoline/thiazole derivatives could be potential candidates for the development of new therapies for neurodegenerative diseases.
