چکیده
A newly reErranged 2(3.20)abeotaxane diterpenoid with a unique 6/1016 skeleton was isolated from the bark of the Chillese yew, Taxus mairei. The structure was established as being 7fi,13(M-diacetoxy-2or,5a,10fi-trihydrexy-9keto-2(3 -20)abeotaxane on the basis of 1-D and 2-D N"M data. The relative stereochemistry was defined from the results of a NOESY experiment. This is the first reported isolation of a rearranged 2(3.20)abeetaxane from Ttzxus

The objective of this study was to isolate endophytic fungi producing paclitaxel from yew for the purpose of paclitaxel manufacture. Surface sterilized bark of Taxus wallichiana var. mairei was used as source material and potato dextrose agar culture medium was used in isolation of endophytic fungi. Fungal cultures were extracted with a mixture of chloroform / methanol (1:1, v/v) and the paclit...

We describe a novel, simple and low-cost protein microarray strategy wherein the microarrays are generated by printing expression ready plasmid DNAs onto slides that can be converted into protein arrays on-demand. The printed expression plasmids serve dual purposes as they not only direct the synthesis of the protein of interest; they also serve to capture the newly synthesized proteins through...
متن کاملCytochrome P450 mono-oxygenases in conifer genomes: discovery of members of the terpenoid oxygenase superfamily in spruce and pine.
Diterpene resin acids, together with monoterpenes and sesquiterpenes, are the most prominent defence chemicals in conifers. These compounds belong to the large group of structurally diverse terpenoids formed by enzymes known as terpenoid synthases. CYPs (cytochrome P450-dependent mono-oxygenases) can further increase the structural diversity of these terpenoids. While most terpenoids are charac...
