摘要 |
The present invention relates to novel 10-deacetyl- 14.beta.-hydroxybaccatine III derivatives in accordance with formula 1. The novel derivatives, having cytotoxic and antitumour activity, are prepared from this synton after functionalization of the hydroxyls at 1-, 14- as thiocarbonate, iminocarbonate and sulfite and possible oxidation of the hydroxyl at C10. These derivatives are subjected to a subsequent esterification at position 13- with a variously substituted isoserine chain. The products of the invention can be administered by the injective or oral route, when suitably formulated. (See formula I)
