Cyanobacteria, also known as Blue-Green algae,  are aquatic photosynthetic procariotes. Some species of cyanobacteria produce toxins that affect animals and humans. People may be exposed to cyanobacterial toxins by drinking or bathing in contaminated water. Toxins from marine or sweet water blue-green algae may endanger marine and sweet-water biosphere. They may contaminate drinking water, water used in pools, water used in infusion solutions. Cyanotoxins are secondary metabolites produced by cyanobacteria, of varied chemical nature and toxic effects.  Among other classes of bioactivities, there are: neurotoxins such as anatoxin-a, anatoxin-a (S), paralytic shellfish toxins, β-methylaminopropionic acid, N-(2-aminoethyl) glycine and 2,4-diaminobutyric acid, cytotoxins/dermatotoxins  and hepatotoxins –cylindrospermopsins, microcystins and nodularins—with microcystins being the most frequently reported. Some Cyanobacterial toxins are cyclic peptides, other are alkaloids or non proteic amino acids, lipopolysacharides.

Description

Tricyclic alkaloid hepatotoxin from a cyanobacterium.

Cylindrospermopsin (abbreviated to CYN, or CYL) is a cyanotoxin produced by a variety of freshwater cyanobacteria. CYL is a polycyclic uracil derivative containing guanidino and sulfate groups. It is also zwitterionic, making it highly water soluble. CYL is toxic to liver and kidney tissue and is thought to inhibit protein synthesis and to covalently modify DNA and/or RNA.

It is not known whether cylindrospermopsin is a carcinogen, but it appears to have no tumour initiating activity in mice. (source: T3DB )

Description

Microcystin-LR (MC-LR) is a toxin produced by fresh water cyanobacteria. It is the most toxic of the microcystins, tumor promoter, potent and selective inhibitor of protein phosphatase 2A (PP2A). Considered to be cell-impermeable with the exception of hepatocytes which take it up via an organic anion pump. Strong hepatotoxin.
