Cytotoxic and other compounds from Didymochlaena truncatula from the Madagascar rain forest. (1/8)
Bioassay-guided fractionation of the EtOH extracts obtained from a plant identified as Didymochlaena truncatula led to the isolation of two cytotoxic alkaloids, camptothecin and 9-methoxycamptothecin. A second plant collection yielded three lignan derivatives, didymochlaenone A (1), didymochlaenone B (2), and (-)-wikstromol, one stilbene, (E)-3-methoxy-5-hydroxystilbene, and two stigmasterol derivatives, stigmast-4-en-3beta-ol and stigmast-4-en-3-one, but no camptothecins, and it is probable that a coding error led to a mistaken identification of the original extract. The structures of the new compounds 1 and 2 were established on the basis of extensive interpretation of one- and two-dimensional NMR spectroscopic data.

AIM: To search for new antiviral agents from traditional Chinese medicine, specifically anti-enteroviruses agents. METHODS: The aqueous extracts (AE) of more than 100 traditionally used medicinal plants in China were evaluated for their in vitro anti-Coxsackie virus B3 activities with a MTT-based colorimetric assay. RESULTS: The test for AE of 16 plants exhibited anti-Coxsackie virus B3 activities at different magnitudes of potency. They can inhibit three steps (inactivation, adsorption and replication) during the infection. Among the 16 plants, Sargentodoxa cuneata (Oliv.) Rehd. et Wils., Sophora tonkinensis Gapnep., Paeonia veitchii Lynch, Spatholobus suberectus Dunn. and Cyrtomium fortunei J. sm. also have activity against other enterovirus, including Coxsackie virus B5, Polio virus I, Echo virus 9 and Echo virus 29. Cell cytotoxic assay demonstrated that all tested AE had CC50 values higher than their EC50 values. CONCLUSION: The sixteen traditionally used medicinal plants in China possessed antiviral activity, and some of them merit further investigations.

Propionibacterium acnes and Staphylococcus epidermidis are pus-forming bacteria that trigger inflammation in acne. The present study was conducted to evaluate the antimicrobial activities of Jeju medicinal plants against these etiologic agents of acne vulgaris. Ethanol extracts of Jeju plants were tested for antimicrobial activities by disc diffusion and broth dilution methods. The results from the disc diffusion assays revealed that four medicinal plants, Mollugo pentaphylla, Angelica anomala, Matteuccia orientalis, and Orixa japonica inhibited the growth of both pathogens. Among these, A. anomala had strong inhibitory effects. Its MIC values were 15.6 microg/ml and 125 microg/ml against P. acnes and S. epidermidis, respectively. The cytotoxic effects of the four extracts were determined by colorimetric MTT assays using two animal cell lines: human dermal fibroblasts and HaCaT cells. Although the M. orientalis root extract had moderate cytotoxicity in HaCaT cells at 200 microg/ml, most extracts exhibited low cytotoxicity at 200 microg/ml in both cell lines. In addition, the extracts reduced the P. acnes-induced secretion of interleukin-8 and tumor necrosis factor-alpha (TNF-alpha) in THP-1 cells, an indication of their anti-inflammatory effects. Based on these results, we suggest that M. pentaphylla, A. anomala, M. orientalis, and O. japonica are attractive acne-mitigating candidates for topical application.

Five new compounds (1-5), were isolated from the rhizomes of Matteuccia orientalis (HOOK.) TREV. The structures of new compounds were elucidated on the basis of their 1D-, 2D-NMR, MS, IR and circular dichroism (CD) data. (+info)Sensitive fern (Onoclea sensibilis) extract suppresses proliferation and migration of vascular smooth muscle cells inflamed by neighboring macrophages. (5/8)
Vascular smooth muscle cell (SMC) migration and proliferation contribute to arterial wound repair and thickening of the intimal layer in atherosclerosis. SMC can physically interact with monocytes and macrophages within the intima. This study evaluated whether macrophages modulated proliferation and migration of SMC in close proximity, which was suppressed by 1-25 microg/ml sensitive fern (Onoclea sensibilis) extract (SFE) inhibiting protein-tyrosine phosphatase-1B activity. The addition of conditioned media of THP-1-derived macrophages substantially promoted human aortic smooth muscle cell (HAoSMC) proliferation by approximately 30%. HAoSMC proliferation was significantly attenuated by >/=10 microg/ml SFE most likely due to its diminution of platelet derived growth factor (PDGF)-BB secreted by neighbor macrophages. HAoSMC migration was also enhanced by culturing in THP-1 macrophage conditioned media, as evidenced by a scratch wound assay. However, the presence of >/=10 microg/ml SFE did not allow such migaration. When SFE was treated to THP-1 macrophages, the secretion of the adipokines, visfatin and resistin, was abrogated. SFE at 1-25 microg/ml dose-dependently diminished resistin-stimulated secretion of collagen IV and connective tissue growth factor (CTGF) in HAoSMC, indicating that macrophage resistin plays a role in the extracellular matrix (ECM) production of vascular SMC. These results demonstrate that SFE disturbed proliferation and migration of SMC instigated by inflammatory macrophages in close proximity. Therefore, this study provides novel information that SFE has the potential capability to prevent atherosclerosis involving SMC proliferation, migration and fibrogenic activation within the vessels.

(+info)"Dryopteris" is a genus of ferns in the family Dryopteridaceae. It includes many species commonly known as wood ferns or buckler ferns. These ferns are characterized by their tough, leathery fronds and their ability to tolerate dry conditions better than some other ferns. They are found in a variety of habitats around the world, including forests, mountains, and rocky areas. Some species of Dryopteris have been used in traditional medicine, but it is important to note that the use of wild plants as medicine should only be done under the guidance of a qualified healthcare professional.
Dryopteridaceae is a family of ferns in the order Polypodiales, also known as the "wood fern" family. It includes several genera of terrestrial and epiphytic ferns, characterized by having typically large, divided fronds with sori (spore cases) protected by an indusium on the underside of the leaf. Examples of genera in this family include Dryopteris, Polystichum, and Athyrium. These ferns are found in a variety of habitats around the world, including temperate and tropical forests.
