A non-toxic analogue of the cyanotoxins cylindrospermopsin and 7-epi-cylindrospermopsin (the latter two have a hydroxy group attached to the carbon adjacent to the uracil ring), it is produced by several species of freshwater cyanobacteria, such as Cylindrospermopsis raciborskii. It has a role as a protein synthesis inhibitor. It is an alkaloid, a member of cylindrospermopsins, an organic sulfate, a pyrimidone and a triazaacenaphthylene. It is a tautomer of a deoxycylindrospermopsin zwitterion."}]
