The syntheses of new tubulysin analogues are described, in which the central amino acid, tubuvaline, is replaced by the rather simple building blocks phenyltubuvaline and phenoxytubuvaline. These analogues can be obtained in only two to three steps from easily accessible starting materials. Although the new derivatives are less active than the tubulysins, their activities towards U-2 OS tumor cells
描述了新 tubulysin 类似物的合成,其中中心氨基酸 tubuvaline 被相当简单的结构单元 phenyltubuvaline 和 phenoxytubuvaline 取代。这些类似物只需两到三个步骤即可从易于获得的起始材料中获得。尽管新衍生物的活性不如微管溶素,但它们对 U-2 OS 肿瘤细胞的活性仍处于纳摩尔范围内。
