- Abstract
- Two new decaline metabolites, wakodecalines A and B, were isolated from a fungus, Pyrenochaetopsis sp. RK10-F058, by screening for structurally unique metabolites using LC/MS analysis. Their structures were determined on the basis of NMR and mass spectrometric measurements. The absolute structures were confirmed by a combination of chemical methods including chemical degradation, a modified Mosher’s method and Marfey’s method, and comparison of the experimental electronic CD (ECD) spectrum with calculated one. Both compounds had a cyclopentanone-fused decaline skeleton and an N-methylated amino acid moiety derived from a serine. They showed moderate antimalarial activity against the Plasmodium falciparum 3D7 strain.
