Scytalidamide A, a cyclic heptapeptide that was recently isolated from a cultured marine fungus of the Genus Scytalidium, was shown to have selective anticancer activity toward CACA-2 colon carcinoma. The first solid-phase total synthesis of scytalidamide A was achieved using two different linker resins, a phenylalanine silane resin and a 4-methoxybenzaldehyde backbone linker resin.
