    A stilbene dimer and flavonoids from the aerial parts of Chromolaena odorata with proprotein convertase subtilisin/kexin type 9 expression inhibitory activity[Pubmed: 32335358]
    Investigation of components of the chloroform-soluble and ethyl acetate-soluble extracts of the aerial parts of Chromolaena odorata L. selected by PCSK9 mRNA expression monitoring assay in HepG2 cells led to the isolation of a new stilbene dimer, (+)-8b-epi-ampelopsin A (1), and 30 known compounds (2-31). The structures of the isolates were established by interpretation of NMR spectroscopic data and the stereochemistry of the new stilbene (1) was proposed based on ECD and NMR calculations. Among the isolates, 1, 5,6,7,4'-tetramethoxyflavanone (6), 5,6,7,3',4'-Pentamethoxyflavanone (7), acacetin (18), and uridine (21) were found to inhibit PCSK9 mRNA expression with IC50 values of 20.6, 21.4, 31.7, 15.0, and 13.7 μM, respectively. Furthermore, the most abundant isolate among the selected compounds, 6, suppressed PCSK9 and low-density lipoprotein receptor protein expression in addition to downregulating the mRNA expression of HNF-1α.

    Synthesis and anti-proliferative activities of 5,6,7-trimethoxyflavones and their derivatives[Pubmed: 34353180]

Their anti-proliferative activity in vitro was evaluated against a panel of four human cancer cell lines (Aspc-1, HCT-116, HepG-2 and SUN-5) by the CTG assay. The results showed that most of the synthetic compounds exhibited moderate to high anti-proliferative activities. In particular, compound 3c possess IC50 (5.30 μM) values below 10 μM against Aspc-1 cells and are worthy of further investigation.

    Polymethoxyflavones in peel of Citrus reticulata 'Chachi' and their biological activities[Pubmed: 28551233]
    Citrus polymethoxyflavones (PMFs) have been of increasing interest due to their extensive biological activities. In the present study, a total of eight PMFs were isolated from the peel of Citrus reticulata 'Chachi' (CRC). They were individually identified as 5-hydroxy-6,7,8,4'-tetramethoxyflavone (1), 5,6,7,3',4'-Pentamethoxyflavanone (2), 5-hydroxy-6,7,8,3',4'-pentamethoxyflavone (3), 3,5,6,7,8,3',4'- heptamethoxyflavone (4), 5,6,7,8,3',4'-hexamethoxyflavone (5), 5,6,7,8,4'-pentamethoxyflavone (6), 6,7,8,3',4'-pentamethoxyflavanone (7) and 5,6,7,3',4'-pentamethoxyflavone (8) by nuclear magnetic resonance and mass spectroscopic analysis. 6,7,8,3',4'-Pentamethoxyflavanone was isolated from the peel of CRC for the first time. The content of PMFs was firstly quantified in both the peel of CRC and PMF-rich extract by HPLC analysis. Furthermore, the biological activities of PMF compounds were investigated. 3,5,6,7,8,3',4'-Heptamethoxyflavone demonstrated potent sterol regulatory element-binding proteins inhibition activity and 5-hydroxy-6,7,8,3',4'-pentamethoxyflavone exhibited strong antiproliferative activity against tumor cell lines. The isolated PMF compounds could also significantly inhibit NO production and the effect varied mainly depending on the number of methoxy groups.
