Used as a key intermediate in the semi-synthesis of paclitaxel, a widely used chemotherapy drug. It is extracted from the needles of the European yew tree and serves as a starting material for producing paclitaxel derivatives. These derivatives are essential in treating various cancers, including ovarian, breast, and lung cancers. Its role in the synthesis process helps reduce reliance on direct extraction from yew bark, promoting sustainability and efficiency in drug production. Additionally, it is studied for its potential in developing new anticancer agents with improved efficacy and reduced side effects.
