Abstract
As part of our plan to discover new bioactive ingredients from entomophagous fungi, a new macrolide compound, talarolide (1), and a new bioactive natural product, talarenal (2), with two known compounds, WF-3681 methy ester (3) and aspergillumarin A (4) were isolated from an insect derived strain Talaromyces rugulosus GIZ45-A37. The structures were determined based on extensive comprehensive spectroscopic (NMR and HR-ESI-MS) analyses and compared with literature values. The relative configuration of 1 was defined by DFT-NMR chemical shift calculations and subsequent DP4/DP4+ probability methods. Compounds 1 and 2 showed inhibitory effect on IL-6 production at 10 and 20 μM in LPS-stimulated beas-2b cells, indicating their potential anti-inflammatory activity.
期刊介绍：
The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds.
The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal.
Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section.
All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
