Molecule ID: 135400191

IUPAC Name: [(4S,5R,6S,8S,10R)-10-[(S)-(2,4-dioxo-1H-pyrimidin-6-yl)-hydroxymethyl]-5-methyl-2,11,12-triazatricyclo[6.3.1.04,12]dodec-1(11)-en-6-yl] hydrogen sulfate

Description: The molecule is a triazaacenaphthylene that is 2,2a,3,4,5,5a,6,7-octahydro-1H-1,8,8b-triazaacenaphthylene which is substituted at positions 3, 4, and 7 by methyl, sulfooxy, and (2,6-dioxo-1,2,3,6-tetrahydropyrimidin-4-yl)(hydroxy)methyl groups, respectively (the 2aS,3R,4S,5aS,7R stereoisomer in which the carbon bearing the hydroxy group has S configuration). It is a cyanotoxin produced by several species of freshwater cyanobacteria, such as Aphanizomenon ovalisporum. It has a role as a cyanotoxin, a protein synthesis inhibitor, a genotoxin and a hepatotoxic agent. It is an alkaloid, a member of cylindrospermopsins, an organic sulfate, a pyrimidone, a secondary alcohol and a triazaacenaphthylene. It is a tautomer of a 7-epi-cylindrospermopsin zwitterion.
