The Palauan deep-water (500 m) marine actinomycete Salinispora pacifica has yielded cyanosporasides A (1731) and B (1732), which feature a chlorine on an unactivated benzene ring (1658). The authors suggest a novel biosynthesis from an enediyne precursor. Related to the previously known nosto-cyclophanes (1) are the new carbamidocyclophanes A-E, of which A (1733), B (1734), C (1735), and D (1736) are chlorinated, being isolated from the Vietnamese cyanobacterium Nostoc sp. (1659). These compounds exhibit cytotoxicity against MCF-7 (breast) and FI (amniotic epithelial) human cancer cells.

MAAs have not been studied as extensively in freshwater as in marine species, but these compounds have been reported in freshwater cyanobacteria, microalgae, invertebrates, and chordates (fish).106 116 130-133 There may be several MAAs unique to freshwater organisms. Aqueous extracts from the cyanobacterium Nostoc commune contain a mixture of UV-absorbing compounds with two distinct chromophores that have maximum absorbance at 312 and 335 nm.134 135 These compounds are comprised of the usual mycosporine cyclohexenone ring structure however, it is...

Reports on anti-HIV compounds isolated from marine algae also included proteins. Cyanovirin N, an 11-kDa protein, was identified in the search for antiviral agents [29]. Boyd et al. [30] isolated and sequenced this protein from cultures of the cyanobacterium Nostoc ellipsosporum. Cyanovirin N irreversibly inactivated diverse laboratory strains and... 

A marine Pseudomonas species WAK-1 produced extracellular glycosaminoglycan and showed anti-HSV-1 activity in RPMI 8226 cells [105], while the water-soluble fraction of the marine diatom Haslea ostrearia delayed HSV-1-induced syncitia formation [17]. A novel acid PS, nostoflan, was isolated from the cyanobacterium Nostoc jlagelliforme, which had a broad antiviral spectrum against enveloped viruses, including HSV-1 and HSV-2, whose cellular receptors are carbohydrates [106]. Two new...
