Abstract

Two new meroterpenoids, named chrodrimanins I and J (1 and 2), together with five known biosynthetically related chrodrimanins (3-7), were isolated from the culture of the Antarctic moss-derived fungus Penicillium funiculosum GWT2-24. Distinguished from all of the reported chrodrimanins, compounds 1 and 2 possess a unique cyclohexanone (E ring) instead of a δ-lactone ring. These structures including the absolute configurations were established on the basis of MS, NMR, and X-ray crystallographic analysis. Compounds 1-7 showed no cytotoxic or Antibacterial activities, while the known compounds 3, 5, and 6 exhibited inhibitory activities against Influenza Virus A (H1N1), with IC50 values ranged from 21 to 57 μM.
