摘要:
The synthesis and biological activity of N-epsilon-Z-[Lys(3)]didemnin B are reported. This novel analogue retains antiproliferative, cytotoxic, and protein biosynthesis inhibition activities, but at reduced levels. This result suggests the use of [Lys(3)]didemnin derivatives as potential affinity probes for studying the molecular target(s) of the didemnin class of natural products.
