Significance

The tubulysins are the most active tubulin-modifying agents known and are candidates for antibody conjugates. Three of the four amino acid components are non-proteinaceous. A key step in the synthesis depicted is the three-component coupling involving the Schöllkopf isonitrile E used to generate the thiazole ring in tubuvaline F.
