The genus Verongia continues to yield tyrosine-derived bromo-compounds. The latest addition to this group is (227) from V. aurea 188). It represents a major departure from the previously reported compounds listed in Chart 1 in having a rearranged dibromotyrosine skeleton. The hypothesis of an oxime precursor of aerothionin (7), homoaerothionin (8) and the nitrile aeroplysinin-1 (4 and 5) (see 15 and 16) has received support by isolation of the oximinopyruvic acid (228) from a marine sponge Hymeniacidon sanguinea 189).
