A New Antimalarial Noreudesmane Sesquiterpenoid from Dobinea delavayi

Abstract

Abstract One previously undescribed angeloylated noreudesmane sesquiterpenoid, dobinin O (1), along with four known eudesmane sesquiterpenoids (2–5) were isolated from the peeled roots of Dobinea delavayi. Their structures were elucidated by extensive spectroscopic data analyses. In addition, compound 1 exhibited moderate antimalarial activity against Plasmodium yoelii BY265RFP with the inhibition ratio of 17.8 ± 13.3% at the dose of 30 mg/kg/day. Graphic Abstract
