Exploring thiazole conjugates as cholinesterase inhibitors for Alzheimer's disease treatment

Alzheimer's Disease (AD), a major global health concern, is marked by memory loss and cognitive decline, especially in the elderly. Cholinergic hypothesis is one of the leading hypotheses toward the treatment of AD, prompting the development of cholinesterase (ChE) inhibitors. Acetylcholinesterase (AChE) remains a vital therapeutic target due to its role in enhancing acetylcholine levels and neural function. The natural products, synthetic analogs, and hybrid molecules have been evaluated as inhibitors of ChEs. Recent studies highlight thiazole-fused heterocyclic scaffolds and their derivatives as promising ChE inhibitors with neuroprotective potential. This article covers the synthesis of conjugates of thiazole with piperazine, benzimidazole, pyrazole, and other heterocyclic compounds, along with their potential as ChE inhibitors. This article will be useful to medicinal chemists and pharmaceutical industries to design and synthesize library of thiazole conjugates.
