Citrinin and α-pyrone derivatives with pancreatic lipase inhibitory activities from sp. SCSIO 41302.

One new citrinin monomer derivative (), and two new natural products α-pyrone analogues ( and ), were isolated from the sponge derived fungus sp. SCSIO 41302. Their structures were determined by extensive spectroscopic analysis, chiral-phase HPLC analysis, modified Mosher's method, ECD calculations, and X-ray single-crystal diffraction.
