  The Multiple Multicomponent Approach to Natural Product Mimics: Tubugis, N-Substituted Anticancer Peptides with Picomolar Activity

  摘要：

  The synthesis of a new generation of highly cytotoxic tubulysin analogues (i.e., tubugis) is described. In the key step, the rare, unstable, and synthetically difficult to introduce tertiary amide-N,O-acetal moiety required for high potency in natural tubulysins is replaced by a dipeptoid element formed in an Ugi four-component reaction. Two of the four components required are themselves produced by other multicomponent reactions (MCRs). Thus, the tubugis represent the first examples of the synthesis of natural-product-inspired compounds using three intertwined isonitrile MCRs.

  The present invention relates to novel tubulysin compounds (tubulysin analogues) as well as pharmaceutical formulations thereof. The present invention further relates to the use of such compounds for medicinal, agricultural, biotool or cosmetic applications. In particular, the novel tubulysin analogues show a cytostatic effect and can therefore be used for the treatment of proliferative disorders. The tertiary amide moiety of the tubulysin analogues (so-called tubugis) according to the present invention is generated by an Ugi-type reaction.
