    HPLC-fingerprints and antioxidant constituents of Phyla nodiflora.[Pubmed: 25140335]
    Phyla nodiflora is a creeping perennial herb, widely distributed in the most tropical and subtropical regions. It has been used as a folk medicine, herbal beverage, or folk cosmetic. For these usages, the development of a chemical quality control method of this plant is necessary. In the present study, ten compounds, namely, 3,7,4',5'-tetrahydroxy-3'-methoxyflavone (1), nodifloretin (2), 4'-hydroxywogonin (3), onopordin (4), Cirsiliol (5), 5,7,8,4'-tetrahydroxy-3'-methoxyflavone (6), eupafolin (7), hispidulin (8), larycitrin (9), and β-sitosterol were isolated from the methanolic extract of the aerial part of P. nodiflora (PNM) and their structures were identified by 1D-NMR comparing their spectra with the literature. The antioxidant activities of these compounds were evaluated by free radical scavenging activity and tyrosinase inhibitory effect in cell-free systems. Compounds 4, 5, and 7 showed strong antioxidant activity.

    Inhibitory effect of chemical constituents from Artemisia scoparia Waldst. et Kit. on triglyceride accumulation in 3T3-L1 cells and nitric oxide production in RAW 264.7 cells.[Pubmed: 24142543 ]
    We investigated the anti-obesity effect of the aerial part of Artemisia scoparia Waldst. et Kit. (Compositae). An 80 % aqueous EtOH extract of the aerial part inhibited triglyceride (TG) accumulation and the nitric oxide (NO) production activity. A new chromane derivative was isolated from the aerial part of A. scoparia Waldst. et Kit. along with 18 known compounds. The structure of the new chromane, scopariachromane (1), was elucidated by spectroscopic analyses. The inhibitory effects of the compounds on TG accumulation activity were examined. Among these, Cirsiliol (11) inhibited TG accumulation in 3T3-L1 preadipocytes. Jaceosidin (12) inhibited NO production in a murine macrophage-like cell line (RAW 264.7). These results indicate that the 80 % aqueous EtOH extract and compounds isolated from the aerial part of A. scoparia Waldst. et Kit. may improve obesity-related insulin resistance.

    Rhamnetin and cirsiliol induce radiosensitization and inhibition of epithelial-mesenchymal transition (EMT) by miR-34a-mediated suppression of Notch-1 expression in non-small cell lung cancer cell lines.[Pubmed: 23902763 ]
    Treatment with rhamnetin or Cirsiliol reduced the proliferation of NSCLC cells through the suppression of radiation-induced Notch-1 expression. Indeed, rhamnetin and Cirsiliol increased the expression of tumor-suppressive microRNA, miR-34a, in a p53-dependent manner, leading to inhibition of Notch-1 expression. Consequently, reduced Notch-1 expression promoted apoptosis through significant down-regulation of the nuclear factor-κB pathway, resulting in a radiosensitizing effect on NSCLC cells. Irradiation-induced epithelial-mesenchymal transition was also notably attenuated in the presence of rhamnetin and Cirsiliol. Moreover, an in vivo xenograft mouse model confirmed the radiosensitizing and epithelial-mesenchymal transition inhibition effects of rhamnetin and Cirsiliol we observed in vitro. In these mice, tumor volume was significantly reduced by combinational treatment with irradiation and rhamnetin or Cirsiliol compared with irradiation alone. Taken together, our findings provided evidence that rhamnetin and Cirsiliol can act as promising radiosensitizers that enhance the radiotherapeutic efficacy by inhibiting radiation-induced Notch-1 signaling associated with radioresistance possibly via miR-34a-mediated pathways.
