A new benzoquinone and a new dihydroflavone from Fissistigma polyanthum and their bioactivity
A new benzoquinone and a new dihydroflavone, fispolyanins A (1) and B (2), along with four known compounds (3–6), were isolated from the ethyl acetate fraction of Fissistigma polyanthum. The structures of 1 and 2 were established primarily by a combination of NMR and MS methods. Compounds 5 and 6 were obtained from F. polyanthum for the first time. Compounds 1, 4, and 6 exhibited inhibitory activities against the production of nitric oxide (NO) in LPS-induced RAW 264.7 cells. Compounds 2 and 4 showed weak anti-oxidant 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.
