Abstract:
:Samoamide A is a cyclic octapeptide rich in proline and phenylalanine residues isolated from an American Samoa marine cyanobacterium, which exhibits potent activity against H460 human non-small-cell lung cancer cells (IC50 of 1.1 μM). The first total synthesis of samoamide A was achieved by employing a strategy of a solid-phase peptide synthesis (SPPS) and a head-to-tail cyclization selecting free steric-hinrance connection sites. Then the final product was purified and identified. This strategy not only provides a basis in producing potent cytotoxic agents for drug discovery, but also provides a reference to the total synthesis of proline-rich peptides.
