taxus mairei/抗癌药

The purpose of this work was to screen the endophytic fungi having antitumor or antifungal activity, which were isolated from the inner barks of three kinds of pharmaceutical plants, Taxus mairei, Cephalataxus fortunei and Torreya grandis, collected from Fujian province, China. Antitumor activity

Taxol is one of the most potent and effective anticancer drugs and is originally isolated from Taxus species. To investigate the specific regulatory mechanisms of taxol synthesis in Taxus wallichiana var. mairei, RNA-seq was conducted to reveal the differences in transcriptional

Paclitaxel is a medicinal ingredient with high anticancer activity and widely used in hospitals and clinics. In this study, we isolate endophytic fungi efficiently producing paclitaxel from yew for the purpose of paclitaxel manufacture.The bark of Taxus wallichiana var. mairei was surface sterilized

A new and 25 known taxane diterpenoids were isolated from the dried whole plants of Taxus wallichiana var. mairei cultivated in the southern area of the Yangtze River in China. The chemical structure of new compound 1, named taxiwallinine, was established by means of MS and NMR analyses. Among the

Taxus mairei (Lemee & Levl.) S.Y. Hu ex Liu is a giant evergreen tree native to Taiwan. T. mairei and the Pacific yew, T. brevifolia, produce taxol, a highly effective antitumor drug. Anthracnose was observed on cuttings and seedlings of T. mairei in nurseries and on larger plants grown in

To study on the 10-deacetyl baccatin III extract from the leaves and branches of Taxus mairei. A new method was proposed to extract and purify 10-DAB III, which was adopted as the parent nucleus of the high efficacious antitumour drug-taxol and docetaxel in the compositive synthesis. Optimization

The diterpenoid taxol is an important anticancer agent used widely in the clinic. The purpose of this work was to identify a taxol-producing endophytic fungus (strain TF5) isolated from Taxus mairei and study its anticancer activities. Strain TF5 was identified as a Tubercularia sp. according to the

Taxol is currently a valuable anticancer drug; however, the accumulated mixture of taxoids can vary greatly among Taxus species. So far, there is very little genomic information for the genus Taxus, except for Taxus baccata. Transcriptome analysis is a powerful approach to explore the different

Taxus species are well-known for paclitaxel, which exhibits antitumor activities and is used for treating various cancers. Although most Taxus species are widespread in many areas, few studies have characterized the variation in metabolism among different Taxus species. Using an integrated approach

The regional variability of Taxus rhizosphere bacterial community composition and diversity was studied by comparative analysis of three large 16S rRNA gene clone libraries from the Taxus rhizosphere in different regions of China (subtropical and temperate regions). One hundred and forty-six clones

BACKGROUND Illumina second generation sequencing is now an efficient route for generating enormous sequence collections that represent expressed genes and quantitate expression level. Taxus is a world-wide endangered gymnosperm genus and forms an important anti-cancer medicinal resource, but the

BACKGROUND Three species of yews Taxus contorta Griff., Taxus mairei (Lemée & Lév.) S.Y. Hu ex T.S. Liu and Taxus wallichiana Zucc. distributed in the Hindu Kush-Himalayan (HKH) region have been commercially exploited in recent decades to extract an anticancer chemotherapeutic drug 'Taxol'.
