Abstract
In order to make more rational use of Flemingia Philippinensis, a systematic separation from the roots of F. philippinensis was performed in the current study. The investigation of chemical constituents resulted in the isolation of a rare prenylated isoflavone-quinone, fleminquinone A (1), together with four known analogues (2-5). Their structures were established by extensive physical and spectroscopic data analysis. Anti-inflammatory activities of the isolated compounds were evaluated in lipopolysaccharide induced mouse mononuclear macrophage leukemia cells RAW 264.7 model. Compound 1 exhibited significant inhibitory effects on LPS-induced NO production and COX-2. Compound 1 also significantly affected the levels of inflammatory cytokines.
期刊介绍：
The Journal of Asian Natural Products Research (JANPR) publishes chemical and pharmaceutical studies in the English language in the field of natural product research on Asian ethnic medicine. The journal publishes work from scientists in Asian countries, e.g. China, Japan, Korea and India, including contributions from other countries concerning natural products of Asia. The journal is chemistry-orientated. Major fields covered are: isolation and structural elucidation of natural constituents (including those for non-medical uses), synthesis and transformation (including biosynthesis and biotransformation) of natural products, pharmacognosy, and allied topics. Biological evaluation of crude extracts are acceptable only as supporting data for pure isolates with well-characterized structures.
All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymized refereeing by at least two expert referees.
