Mass-directed fractionation based on a Trypanosoma brucei brucei active fraction from the Australian sponge Pseudoceratina sp. led to the isolation of a novel bromotyrosine alkaloid, pseudoceratinazole A (1). Compound 1 is the first dimeric bromotyrosine alkaloid containing an imidazole-bridging moi
Mass-directed isolation of the CH 2 Cl 2 /CH 3 OH extract from a marine sponge of the genus Pseudoceratina resulted in the purification of a new antimalarial bromotyrosine alkaloid, psammaplysin H (1), along with the previously isolated analogs psammaplysins G (2) and F (3). The structure of 1 was e
