Taxus cuspidata (Japanese yew) pollen nasal allergy.
We have investigated the Taxus cuspidata pollinosis that has never been studied before. We applied immunoblotting method in order to detect specific IgE antibody against T. cuspidata using its pollen itself. Out of 18 patients with seasonal allergic rhinitis suffering mainly in April and May, 5 patients were sensitized with this pollen. Furthermore, we were able to diagnose one case as T. cuspi...
متن کاملMolecular cloning and characterization of the yew gene encoding squalene synthase from Taxus cuspidata.
The enzyme squalene synthase (EC 2.5.1.21) catalyzes a reductive dimerization of two farnesyl diphosphate (FPP) molecules into squalene, a key precursor for the sterol and triterpene biosynthesis. A full-length cDNA encoding squalene synthase (designated as TcSqS) was isolated from Taxus cuspidata, a kind of important medicinal plants producing potent anti-cancer drug, taxol. The full-length cD...
متن کاملHistone Deacetylase Inhibitory and Cytotoxic Activities of the Constituents from the Roots of Sophora Pachycarpa
Four prenylated flavonoids including isosophoranone, sophoraflavanone G, alopecurone J, alopecurone P and a resveratrol derivative HPD (2-(4-hydroxyphenyl)-2,3-dihydrobenzo[b] furan-3,4,6-triol), were isolated from the roots of Sophora pachycarpa. The cytotoxic activity of obtained compounds was evaluated against A2780, A549, HeLa, and HCT116 human cancer cell lines. We also evaluated their his...
متن کاملNew taxane diterpenoids from the roots of Taiwanese Taxus mairei.
Five new taxane diterpenoids, taxumairols G (1), H (2), I (3), J (4), and L (5) were isolated from extracts of the roots of Taiwanese Taxus mairei (LEMEE & LEVL.) S. Y. Hu. Compounds 1-4 belong to the new 11(15-->1)-abeo-taxene system, having a tetrahydrofuran ring along carbons C-2, C-3, C-4 and C-20. Compounds 3 and 4 contain an isopropenyl group at C-1 while compounds 1 and 2 are attached wi...
