Abstract
In this study, we report the generation of a polymer based dynamic combinatorial library (DCL) using aldehyde-functionalized linear poly(glycidol) and hydrazide derivatives as initial building blocks. In combination with tetrameric acetylcholinesterase (AChE), a certain type of amplified acylhydrazone side chain is identified and further used for the synthesis of a multivalent AChE inhibitor. The cytotoxicity and inhibition properties of the multivalent inhibitor are evaluated, and the results indicate superior bioactivity compared to the commercial reference Edrophonium chloride.
