Cyanobacteria blooms can pose an extremely serious threat to human health (970-972), and some of the causative toxins contain halogen. The fresh water toxic cyanobacterium Oscillatoria agardhii produces oscillaginin A (916), which features the novel 3-amino-10-chloro-2-hydroxydecanoic acid, and is the source of the micro-cystins, which are heptatoxins (973). The prolific cyanobacterium Lyngbya majuscula from Curacao has furnished the novel barbamide (917) (974) and dechlorobarbamide (918) (975). Extensive biosynthetic studies show that the amino acids leucine, cysteine, and phenylalanine are involved in barbamide production (976-982). The chlorination of leucine is of great interest and may involve a radical mechanism (976, 980-983).

Figure 3.6. A microcystin containing 2-amino-2-butenoic add (Dhb), isolated from Oscillatoria agardhii. It also contains Adda, D-Ala, d-G1u, D-Asp and two L-Arg residues. It is, strictly speaking, an isopeptide, since the aspartic and glutamic add residues are linked through their side-chain carboxy groups.

The genus Oscillatoria (order Oscillatoriales, 64 compounds total) has a much broader distribution of isolated compounds among different species as compared to the other genera of cyanobacteria 30% comes from undetermined species, 28% from Oscillatoria agardhii, 19% from Oscillatoria nigroviridis, and 13% from Oscillatoria spongelia. The species Oscillatoria raoi and Oscillatoria acutissima are responsible for 3% each and Oscillatoria rosea and Oscillatoria amphibia each accounts for 2%.
