Synthesis and biological evaluation of the [d-MeAla(11)]-epimer of coibamide A.

Abstract：

:Coibamide A is a highly potent antiproliferative cyclic depsipeptide, which was originally isolated from a Panamanian marine cyanobacterium. In this study, the synthesis of coibamide A has been investigated using Fmoc-based solid-phase peptide synthesis followed by the cleavage of the resulting linear peptide from the resin and its subsequent macrolactonization. The peptide sequence of the linear coibamide A precursor was constructed on a solid-support following the optimization of the coupling conditions, where numerous coupling agents were evaluated. The macrocyclization of the resulting linear peptide provided the [d-MeAla(11)]-epimer of coibamide A, which exhibited nanomolar cytotoxic activity towards a number of human cancer cell lines.
