[Design, synthesis and evaluation of 4-pyridinylthiazole-2-amines as acetylcholinesterase inhibitors].

Alzheimer’s disease (AD) is a degenerative disease of the nervous system. Compound I reported to have inhibitory activity on AChE was used as a lead compound in this study, and 4-pyridinylthiazole-2-amines were designed by optimizing compound I structure. The new compounds were synthesized from acetylpyridines through five-steps of reaction, and their inhibition activities on AChE were measured in vitro by Ellman method.
