| sequestration of host plant-derived compounds by geometrid moth, milionia basalis, toxic to a predatory stink bug, eocanthecona furcellata. | a predatory stink bug, eocanthecona furcellata, died after feeding on milionia basalis larvae. the compounds toxic to e. furcellata were isolated from the hemolymph of m. basalis larvae and identified as inumakilactone a, nagilactone c, and nagilactone c glucoside. the concentrations of inumakilactone a, nagilactone c, and nagilactone c glucoside in the hemolymph of the final instar larvae were 130, 50, and 770 microg/ml, respectively. nagilactone c showed the highest insecticidal activity again ... | 2001 | 11504032 |
| s(r)-podolactone d, a new sulfoxide-containing norditerpene dilactone from podocarpus macrophyllus var. maki. | s(r)()-podolactone d (1), a new norditerpene dilactone having a methylsulfoxide moiety, was isolated from the leaves of podocarpus macrophyllus d. don var. maki endl. along with known podolactone d (2, s(s)()-podolactone d). the structures and absolute configurations of compounds 1 and 2 were elucidated by spectral methods (hreims, ir, (1)h, (13)c, and 2d nmr) and finally confirmed by single-crystal x-ray analyses. the cytotoxic effects of compounds 1 and 2 on p388 murine leukemia cells were als ... | 2003 | 12608867 |
| a rhizobia strain isolated from root nodule of gymnosperm podocarpus macrophyllus. | symbiotic nitrogen fixation of rhizobia and leguminous plants is considered as the most important biologic nitrogen fixation system on earth. symbiotic nodulation of gymnosperm podocarpus macrophyllus and rhizobia has never been reported. in this study, 11 endophytic bacteria strains were isolated from root nodules of p. macrophyllus and its variation p. macrophyllus var. maki. the plant infection tests on these strains indicated that the isolated strains could be nodulated on p. macrophyllus pl ... | 2007 | 17447030 |
| new constituent from podocarpus macrophyllus var. macrophyllus shows anti-tyrosinase effect and regulates tyrosinase-related proteins and mrna in human epidermal melanocytes. | a new biflavonoid, 2,3-dihydro-4',4'''-di-o-methylamentoflavone (5), and five known compounds, (-)-catechin (1), quercetin (2), 2,3-dihydrosciadopitysin (3), sciadopitysin (4), and isoginkgetin (6), were isolated from podocarpus macrophyllus var. macrophyllus (podocarpaceae). these compounds were evaluated their ability to inhibit cellular tyrosinase activity and for their melanin inhibitory activity in human epidermal melanocytes (hemn). in the melanin synthesis assay, 2,3-dihydro-4',4'''-di-o- ... | 2007 | 17473463 |
| antibacterial novel phenolic diterpenes from podocarpus macrophyllus d. don. | two new sempervirol type diterpenes, inumakiols a, b, and six new totarol type diterpenes, inumakiols c-h, were isolated from a methanolic extract of bark of podocarpus macrophyllus (podocarpaceae), along with one known abietane, two known totarol type diterpenes, and one known totarol type diterpene dimer. the structures of the new compounds were elucidated by the spectroscopic methods. some of them possessed antibacterial activity against oral pathogenic microorganisms with minimum inhibitory ... | 2008 | 19043241 |
| cytotoxic bisnor- and norditerpene dilactones having 7alpha,8alpha-epoxy-9,11-enolide substructure from podocarpus macrophyllus d. don. | fourteen new bisnor- and norditerpene dilactones, makilactones e-r, having a 7alpha : 8alpha-epoxy-9,11-enolide substructure, were isolated from a methanolic extract of the root and the bark of podocarpus macrophyllus d. don (podocarpaceae) with thirteen known bisnor- and norditerpenoids, and the structures of those new bisnor- and norditerpenoids were determined on the basis of their spectroscopic studies. of the thirteen known ones isolated, the structures of two, i.e., podolactone b and inuma ... | 2009 | 19571410 |
| Phthalide derivatives with antifungal activities against the plant pathogens isolated from the liquid culture of Pestalotiopsis photiniae. | Three new phthalide derivatives (1-3) named 5-(3'-methyl-2'-butenyl)-2-hydroxy-3-methoxy-4-methylbenzoic acid (1), 5-(3'-carboxyl-3'-methyl-2E-allyloxy)-3-methoxy-4-methylphthalide (2) and 5-(3',3'-dimethylallyloxy)-2-methoxycarbonyl-3-methoxy-4-methylbenzoic acid (3) together with six known phthalide derivatives named 5-(3',3'-dimethylallyloxy)-3-methoxy-4-methylphthalide (4), zinnimidine (5), 5-(3',3'-dimethylallyloxy)-3-methoxy-4-methylphthalide (6), 5-(3',3'-dimethylallyloxy)-3-methoxy-4-met ... | 2011 | 21915132 |
