摘要:
The condensation of tacrine aminopolymethylene derivatives with diethyl (ethoxymethylidene)malonate led to the new hybrid compounds-conjugates, which were the effective inhibitors of acetylcholinesterase (AChE) (IC50 up to 0.538 mu M) and butyrylcholinesterase (IC50 up to 0.0314 mu M). They can displace propidium iodide from peripherical anionic site of AChE at the level of the reference drug donepezil and demonstrate a weak antioxidant activity. Conjugates are of interest for further extended research as potential drugs for the Alzheimer's disease treatment.
