Abstract
Nine new phenalenone derivatives (1-9), along with two known analogues (10-11) have been isolated from the solid cultures of an endophytic fungus Aspergillus sp. which was obtained from Pinellia ternate. Their structures were established through interpretations of spectroscopic evidence, and some of their absolute configurations were determined by electronic circular dichroism (ECD) and Mo2(OCOCH3)4 induced ECD. All of the phenalenones are unusual acyclic diterpenoid adducts, which are diversely oxidized and partly epoxidized to form different heterocycles. In addition, compound 10 exhibited significant antimicrobial activity against Pseudomonas aeruginosa, Staphylococcus aureus, and Bacillus subtilis with MIC50 values of 1.87, 2.77, and 4.80μg/mL, respectively.

Abstract
It was shown that racemic (±)-2 [1'-benzyl-3-(3-fluoropropyl)-3H-spiro[[2]benzofuran-1,4'-piperidine], WMS-1813] represents a promising positron emission tomography (PET) tracer for the investigation of centrally located σ(1) receptors. To study the pharmacological activity of the enantiomers of 2, a preparative HPLC separation of (R)-2 and (S)-2 was performed. The absolute configuration of the enantiomers was determined by CD-spectroscopy together with theoretical calculations of the CD-spectrum of a model compound. In receptor binding studies with the radioligand [(3)H]-(+)-pentazocine, (S)-2 was thrice more potent than its (R)-configured enantiomer (R)-2. The metabolic degradation of the more potent (S)-enantiomer was considerably slower than the metabolism of (R)-2. The structures of the main metabolites of both enantiomers were elucidated by determination of the exact mass using an Orbitrap-LC-MS system. These experiments showed a stereoselective biotransformation of the enantiomers of 2.
