Abstract
Two previously undescribed isopimarane diterpene glycosides, namely xylarisides A (1) and B (2), along with five known analogues (3 −7), were characterized from the fermentation products of the fungus Xylaria sp. ZY-13, isolated from the medicinal plant Cephalotaxus fortunei Hook. The structural characterization and absolute stereochemistry of two previously unreported compounds were identified utilizing comprehensive modern spectroscopic approaches, electronic circular dichroism analyses, and acid hydrolysis of sugar. Additionally, we assessed the in vitro anti-inflammatory effects of all compounds, and only 7 showed weak inhibitory activities.
期刊介绍:
Phytochemistry Letters invites rapid communications on all aspects of natural product research including:
• Structural elucidation of natural products
• Analytical evaluation of herbal medicines
• Clinical efficacy, safety and pharmacovigilance of herbal medicines
• Natural product biosynthesis
• Natural product synthesis and chemical modification
• Natural product metabolism
• Chemical ecology
• Biotechnology
• Bioassay-guided isolation
• Pharmacognosy
• Pharmacology of natural products
• Metabolomics
• Ethnobotany and traditional usage
• Genetics of natural products
Manuscripts that detail the isolation of just one new compound are not substantial enough to be sent out of review and are out of scope. Furthermore, where pharmacology has been performed on one new compound to increase the amount of novel data, the pharmacology must be substantial and/or related to the medicinal use of the producing organism.
