Three previously undescribed metabolites from Cordyceps cicadae JXCH-1, an entomopathogenic fungus
Three previously undescribed compounds, cordycicadione (1), cordycicadin F (2), and 7-hydroxybassiatin (3), were isolated from the cultures of Cordyceps cicadae JXCH1, an entomopathogenic fungus. Their structures and relative configurations were elucidated primarily by NMR spectroscopic analysis. The absolute configurations of 1 and 2 were determined by ECD calculations. Single-crystal X-ray diffraction method was adopted to determine the absolute configuration of 3. Compound 2 is a polycyclic polyketide with an unusual enol ether moiety and a spiro ring. The compounds obtained in this study were subjected to screening their inhibition against the proliferation of the human lung cancer cell line A549 and the production of nitric oxide in murine macrophages RAW264.7.
期刊介绍：
Natural Products and Bioprospecting serves as an international forum for essential research on natural products and focuses on, but is not limited to, the following aspects:
Natural products: isolation and structure elucidation
Natural products: synthesis
Biological evaluation of biologically active natural products
Bioorganic and medicinal chemistry
Biosynthesis and microbiological transformation
Fermentation and plant tissue cultures
Bioprospecting of natural products from natural resources
All research articles published in this journal have undergone rigorous peer review. In addition to original research articles, Natural Products and Bioprospecting publishes reviews and short communications, aiming to rapidly disseminate the research results of timely interest, and comprehensive reviews of emerging topics in all the areas of natural products. It is also an open access journal, which provides free access to its articles to anyone, anywhere.
