A marine actinomycete (MST-MA190) isolated from a sample of beach sand coll
ected near Lorne on the southwest coast of Victoria, Australia, has yielded
two new aromatic amides, lorneamide A (1) and lorneamide B (2). The lornea
mides belong to a novel class of tri-alkyl-substituted benzenes, and their
structures were determined by spectroscopic methods.
