title: Psammaplysin C: a new cytotoxic dibromotyrosine-derived metabolite from the marine sponge Druinella (= Psammaplysilla) purpurea.
abstract: The new, cytotoxic dibromotyrosine-derived metabolite psammaplysin C [3], in addition to the two known psammaplysins A [1] and B [2], was isolated from the marine sponge Druinella purpurea. All three compounds were found to possess moderate in vitro cytotoxicity towards the human colon tumor cell-line HCT116.
