Abstract

A new highly selective inhibitor of acetylcholinesterase (AChE) was discovered by high-throughput screening. Compound 1 was synthesized from a natural product, the N-3-isobutyrylcycloxobuxidine-F 2. A new extraction protocol of this compound is described. The hemisynthesis and optimization of 1 are reported. The analogs of 1 were tested in vitro for the inhibition of both cholinesterases (AChE and BuChE). These compounds selectively inhibited AChE. Extensive molecular docking studies were performed with 2 and AChE employing Discover Biosym software to rationalize the binding interaction. The results suggested that ligand 2 binds simultaneously to both catalytic and peripheral sites of AChE.
