Natural product acyl-CoA:cholesterol acyltrasferase (ACAT) inhibitor pyripyropene A was synthetically converted to acetylcholinesterase (AChE) inhibitor via heterolitic cleavage of the 2-pyrone ring, followed by γ-acylation/cyclization with several aroyl chlorides. The 4-pyridyl analogue selectively showed AChE inhibitory activity (IC50 = 7.9 μM) and no ACAT inhibitory activity IC50 = > 1000 μM. (C) 2000 Elsevier Science Ltd. All rights reserved.
