The dysideathiazoles (420-424) were also reported from the same sponge and their structures were determined by spectroscopic methods and X-ray analyses [326]. More recently, new variations of this type of unique marine metabolite were obtained. Herbamide A (425) [327] was isolated from a collection of D. herbacea, presumed to be rich in cyanobacteria because of the rich presence of chrorophyll, and barbamide (426) [328] was obtained from the cyanobacterium Lyngbya majuscula.

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). 

Reports on the anti-influenza virus effects of extracts from marine algae from all over the world have been found in the literature [115]. These results show that the blue-green algae (cyanobacterium) are able to produce compounds with anti-influenza activity that may be of potential clinical interest. For example, aqueous and methanolic extracts of cultured cyanobacteria of several genera. Microcystis, Nodularia, Oscillatoria, Scytonema, Lyngbya and Calothrix were evaluated for their in vitro antiviral activity against the influenza A virus in Madin Darby kidney cells [116,117]. The further analysis of methanolic extracts of cultured strains of genus Microcystis revealed a remarkable antiviral...
