    Studies on coumarins from fruit of Cnidium monnieri and their cytotoxic activities.[Pubmed: 26983206]
    This study is to study is to investigate the coumarins from Fruit of Cnidium monnieri and their cytotoxic activities.
    The constituents were separated by column chromatography, and their structures were elucidated by spectroscopic data analyses. The isolated compounds were evaluated for their cytoxic activities by MTT method. Eleven compounds were isolated and identified as osthole (1), bergaptan (2), xanthotoxol (3), xanthotoxin (4), imperatorin (5), isopimpinellin (6), Osthenol (7), psoralen (8), 5,7-dimethoxycoumarin (9), oxypeucedaninhydrate (10), and swietenocoumarin F (11). Compounds 7, 9-11 were isolated from the Cnidium genus for the first time.
    Compounds 1,5,10 and 11 showed significant cytotoxic activities against L1210 cell lines at a concentration of 1 x 10(-5) mol x L(-1) with inhibitory rates of were 70.13, 63.10, 55.77, and 75.08% respectively.

    Antifungal activity of coumarins.[Pubmed: 18386483 ]

    The antifungal activity of 40 coumarins was tested against the fungal strains: Candida albicans (ATCC 14053), Aspergillus fumigatus (ATCC 16913) and Fusarium solani (ATCC 36031), using the broth microdilution method.
    Osthenol showed the most effective antifungal activity among all the compounds tested, with a MIC value of 125 microg/ml for Fusarium solani and 250 micro/ml for Candida albicans and Aspergillus fumigatus. The antifungal potential of this prenylated coumarin can be related to the presence of an alkyl group at C-8 position.

    Antibacterial activity of coumarins.[Pubmed: 16320610 ]

    The antibacterial activity of coumarin per se and other 45 coumarin derivatives was tested against strains of Bacillus cereus MIP 96016, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, and Staphylococcus aureus ATCC 25923. The inhibitory effects of coumarins were affected by their substitution patterns. Osthenol (44) showed the most effective antibacterial activity against Gram-positive bacteria with MIC values ranging between 125 and 62.5 microg/ml.
    These results suggested that the prenyl chain of 44 at position 8 and the presence of OH at position 7 of the benzenic ring are required for the antibacterial activity against these strains.

    Osthenol, a prenylated coumarin, as a monoamine oxidase A inhibitor with high selectivity.[Pubmed: 30686752]

    Osthenol (6), a prenylated coumarin isolated from the dried roots of Angelica pubescens, potently and selectively inhibited recombinant human monoamine oxidase-A (hMAO-A) with an IC50 value of 0.74 µM and showed a high selectivity index (SI > 81.1) for hMAO-A versus hMAO-B. Compound 6 was a reversible competitive hMAO-A inhibitor (Ki = 0.26 µM) with a potency greater than toloxatone (IC50 = 0.93 µM), a marketed drug. Isopsoralen (3) and bakuchicin (1), furanocoumarin derivatives isolated from Psoralea corylifolia L., showed slightly higher IC50 values (0.88 and 1.78 µM, respectively) for hMAO-A than 6, but had low SI values (3.1 for both). Other coumarins tested did not effectively inhibit hMAO-A or hMAO-B. A structural comparison suggested that the 8-(3,3-dimethylallyl) group of 6 increased its inhibitory activity against hMAO-A compared with the 6-methoxy group of scopoletin (4). Molecular docking simulations revealed that the binding affinity of 6 for hMAO-A (-8.5 kcal/mol) was greater than that for hMAO-B (-5.6 kcal/mol) and that of 4 for hMAO-A (-7.3 kcal/mol). Docking simulations also implied that 6 interacted with hMAO-A at Phe208 and with hMAO-B at Ile199 by carbon hydrogen bondings.
    Our findings suggest that Osthenol, derived from natural products, is a selective and potent reversible inhibitor of MAO-A, and can be regarded a potential lead compound for the design of novel reversible MAO-A inhibitors.

    Inhibitors of 5alpha -reductase type I in LNCaP cells from the roots of Angelica koreana.[Pubmed: 11859469]

    A prenylated coumarin, Osthenol (1) and a sesquiterpene, bisabolangelone (2) have been isolated as active principles with 5alpha-reductase type I inhibitory effects in LNCaP cells from the roots of Angelica koreana Max. by bioassay-guided chromatographic fractionation.
    Osthenol exhibited a highly potent inhibitory activity on 5alpha-reductase type I in LNCaP cells with an IC50 value of 0.1 microg/ml, which is about 200 times more potent than the positive control, finasteride (IC50 = 19.8 microg/ml). Bisabolangelone also inhibited the activity of 5alpha-reductase type I in LNCaP cells (IC50 = 11.6 microg/ml), indicating that these compounds are possible candidates for the development of new drugs to treat human endocrine disorders associated with overproduction of DHT by 5 alpha-reductase type I. In addition, four compounds isooxypeucedanin, oxypeucedanin hydrate, oxypeucedanin and isoimperatorin were also isolated and found to be inactive in the 5alpha-reductase assay systems used in the present study.

    Inhibitory effects of Angelica pubescens f. biserrata on 5-lipoxygenase and cyclooxygenase.[Pubmed: 9741298 ]

    Linoleic acid, osthol, Osthenol and two polyacetylenes, falcarindiol and 11(S),16(R)-dihydroxyoctadeca-9Z,17-diene-12,14-diyn-1 -yl acetate were found to be the most active compounds responsible for the inhibitory activity of the dichloromethane extract of the roots of Angelica pubescens f. biserrata on 5-lipoxygenase (5-LO) and cyclooxygenase (COX-1) in vitro.
    They showed prominent inhibitory effect on 5-LO with IC50 values of 27.9 microM, 36.2 microM, 43.1 microM, 9.4 microM and 24.0 microM, respectively. Linoleic acid, Osthenol, falcarindiol and 11(S), 16(R)-dihydroxyoctadeca-9Z,17-diene-12,14-diyn-1-yl acetate exhibited inhibitory activity on COX-1 with IC50 values of 13.3 microM, 64.3 microM, 66.0 microM and 73.3 microM.

    Antitumor-promoting activity of coumarins from citrus plants.[Pubmed: 15678381]

    In order to identify antitumor-promoting agents, we performed primary in vitro screening of 31 coumarins isolated from 11 plants of the Citrus species (Rutaceae), examining their possible inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) activation induced by 12- O-tetradecanoylphorbol-13-acetate (TPA) in Raji cells. Some of the 8-substituted coumarins, 8-formyl-7-hydroxycoumarin (5), Osthenol (7), demethylauraptenol (8), osthenon (9) and dihydroosthenon (10), were found to significantly inhibit EBV-EA activation (IC50: 129-207 mol ratio/32 pmol TPA).
    Osthenol (7) exhibited a marked inhibitory effect on mouse skin tumor promotion in an in vivo two-stage carcinogenesis test.
