Provided herein is a taxane having a hydrocarbon attached at the 2′ and/or 7 positions, the hydrocarbon's alpha position being occupied by a “hydrolysis-promoting group” (“HPG”). In one embodiment, the hydrolysis promoting group is stereospecifically attached to the &agr;-carbon of the hydrophobic taxane. The Substitution of an HPG for the methylene unit ordinarily occupying the alpha position allows for enhanced in vivo hydrolysis of the hydrocarbon-taxane bond, and hence, for enhanced taxane therapeutic activity. Also provided herein are taxane-containing compositions, and methods of administering taxanes to animals, including those afflicted with cancers or inflammatory diseases.
本文提供了一种在 2′和/或 7 位连接有碳氢化合物的类
固醇,碳氢化合物的 α 位被 "
水解促进基"("H
PG")占据。在一个实施方案中,
水解促进基团立体定向地连接到疏
水紫杉烷的&agr;-碳上。用 H
PG 取代通常占据α位的亚甲基单元,可增强碳氢化合物-
紫杉烷键的体内
水解,从而增强
紫杉烷的治疗活性。本文还提供了含
紫杉烷的组合物,以及向动物(包括患有癌症或炎症疾病的动物)施用
紫杉烷的方法。
