Abstract
A new diarylpropane (1) along with seventeen known compounds (2–18), were extracted from the entire plant of Dianella ensifolia. The compounds 1–3 were identified as a distinctive group of diarylpropanes. Their structures were determined through comprehensive spectral analysis. An anti-inflammatory activity assay revealed that compound 7 demonstrated significant inhibitory effects on NO generation in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells, with an IC50 value of 9.93 μg/mL. Further in-depth mechanistic studies indicated that compound 7 suppresses LPS-induced NO production by inhibiting the activation of NF-κB, which subsequently led to a decrease in the expression of nitric oxide synthase enzymes (iNOS).
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.
