要旨

Belchinoids A–C (1–3), three unusual nor-sesquiterpenoids, along with a new isoflavone (4), were isolated from the roots of Belamcanda chinensis, a traditional Chinese medicine. To the best of our knowledge, compound 1 represents the first C13 nor-sesquiterpenoid with a five membered carbon ring. Compounds 2 and 3 are rare C14 chained nor-sesquiterpenoids. Their structures were fully characterized based on extensive spectroscopic data and quantum chemistry calculation. Three compounds (1, 2, and 4) showed potent inhibitory effects on lipid accumulation in an oleic acid-treated HepG2 cell model. In particular, compound 2 exhibited the most potent inhibitory effect on triglyceride accumulation at a low concentration of 2.5 μM, better than the positive control atorvastatin. The plausible biosynthetic pathway of the three nor-sesquiterpenoids (1–3) is also proposed.

Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
