Wild ruminants, including deer species (cervids) have incorrectly been regarded as refractory to yew (Taxus) intoxication. This assumption has been based upon anecdotal observations of individual deer browsing on yew over time without apparent adverse effect. A single case of yew intoxication was
Taxus baccata (L) known as Sthauneyaka in Sanskrit(1) has wide range of biological activities including analgesic, anti-malarial, anti-rheumatic, sedative, anti-spasmodic, aphrodisiac and anti-asthmatic. In the present study, the dried and powdered bark of Taxus baccata (L) was extracted with 95%
Current study was conducted to identify constituents of Taxus wallichiana Zucc. that might be responsible for its folk use in anti-inflammatory conditions. Taxusabietane A was isolated from the bark extract of Taxus wallichiana Zucc. Taxusabietane A was analyzed for in-vitro and in-vivo
Plants of the genus Taxus are common ornamental shrubs that contain cardiotoxic alkaloids. Gross lesions consistent with heart failure are frequently reported in fatal cases; however, microscopic lesions in the heart have not been well characterized. The current report describes 2 related outbreaks
Four taxoids (taxusin, baccatin VI, baccatin III and 1beta-hydroxybaccatin I) and five lignans (lariciresinol, taxiresinol, 3'-demethylisolariciresinol-9'-hydroxyisopropylether, isolariciresinol and 3-demethylisolariciresinol) were isolated from the heartwood of Taxus baccata L. (Taxaceae) growing
Already the Celts and ancient Germanic peoples knew about the poisonousness of the yew, which played an important part in the mythology of these civilizations. For hunting, the arrows were made poisonous with yew juice, and yew leaves were used for homicide and suicide. In modern times taxine is
Docetaxel is a complex diterpene obtained from Taxus Brevifolia, and it is one of the most widely used anticancer agents. The main mechanism of citotoxic action depends on stabilization of microtubules leading to cell mitotic arrest. Independently from the schedule, the primary dose limiting
Thirty-five privately owned 1- to 2-year-old mixed-breed steers and heifers, weighing 340 to 454 kg, died from accidental ingestion of English yew (Taxus baccata). Estimated dosages ranged from 0.36 to 0.70 g of fresh plant/kg of body weight. Clinical signs of poisoning and death began 2 to 3 hours
BACKGROUND
Docetaxel (Taxotere) is prepared from a noncytotoxic precursor extracted from the needles of the Taxus baccata. Preclinical investigations have demonstrated that docetaxel is very active in colon adenocarcinoma murine models. Phase I studies revealed granulocytopenia to be the
Plants are used worldwide for the treatment of diseases, and novel drugs continue to be developed through research from plants. There are more than 20,000 species of plants used in traditional medicines, and these are all potential reservoirs for new drugs. Cucurbitapepo has been used in traditional
It is impossible to predict what compounds of pharmacological interest may be present in an unexamined species. The extinction of such species may result, therefore, in the loss of therapeutically significant compounds. The fact that science will never know what has been lost does not lessen the
