[{"from": "human", "value": "Synthesize a molecule that matches the given characteristics. The molecule is a cyclic purine nucleotide that is cyclic ADP-ribose substituted at position O-2' by a phospho group. It has a role as a signalling molecule, a calcium channel agonist and a metabolite. It is a nucleotide-sugar and a cyclic purine nucleotide. It is functionally related to a cyclic ADP-beta-D-ribose. It is a conjugate acid of a 2'-phospho-cyclic ADP-ribose(3-)."}, {"from": "gpt", "value": "[C][C@@H1][C@H1][Branch2][=Branch1][#Branch2][C@H1][Branch2][Branch1][=N][C@@H1][Branch1][Ring2][O][Ring1][Branch1][N][C][=N][C][=C][Ring1][Branch1][N][=C][N+1][=Branch1][Branch1][=C][Ring1][=Branch1][N][C@H1][C@@H1][Branch2][Ring1][P][C@@H1][Branch2][Ring1][N][C@H1][Branch1][Ring2][O][Ring1][Branch1][C][O][P][=Branch1][C][=O][Branch1][=N][O][P][=Branch1][C][=O][Branch1][Branch1][O][Ring2][Ring1][=N][O][O][O][O][O][P][=Branch1][C][=O][Branch1][C][O][O][O]"}]
