DescriptionCylindrospermopsin (abbreviated to CYN, or CYL) is a cyanotoxin produced by a variety of freshwater cyanobacteria. CYN is a polycyclic uracil derivative containing guanidino and sulfate groups. It is also zwitterionic, making it highly water soluble. CYN 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.

Chemical Taxonomy
Description belongs to the class of organic compounds known as pyridopyrimidines. Pyridopyrimidines are compounds containing a pyridopyrimidine, which consists of a pyridine fused to a pyrimidine. Pyridine is 6-membered ring consisting of five carbon atoms and a nitrogen atom. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions.
