Task: Please create a description for a molecule.
Molecule SMILES: O=c1ccn([C@@H]2O[C@@H]3COP(=O)([O-])O[C@H]4[C@@H](O)[C@H](n5ccc(=O)[nH]c5=O)O[C@@H]4COP(=O)([O-])O[C@H]3[C@H]2O)c(=O)[nH]1
Constraint: Answer the question with complete sentences.
Result: The molecule is a cyclic pyrimidine dinucleotide that consists of two UMP units cyclised via 3',5'-linkages, major species at pH 7.3. It is an organophosphate oxoanion and a cyclic pyrimidine dinucleotide.
