[{"from": "human", "value": "Based on the given information, design a molecule that meets the desired specifications. The molecule is a nucleoside 3',5'-cyclic phosphorothioate having 8-bromoguanine as the nucleobase (the Sp-stereoisomer). It has a role as a protein kinase agonist. It is a nucleoside 3',5'-cyclic phosphorothioate, an organobromine compound and a member of purines. It is functionally related to a 3',5'-cyclic GMP."}, {"from": "gpt", "value": "[C][C@@H1][C@H1][Branch2][Ring2][C][C@H1][Branch2][Ring1][=N][C@@H1][Branch1][Ring2][O][Ring1][Branch1][N][C][=C][Branch1][=N][C][=Branch1][C][=O][N][C][=Branch1][Ring2][=N][Ring1][#Branch1][N][N][=C][Ring1][O][Br][O][O][P][=Branch1][C][=S][Branch1][Branch1][O][Ring2][Ring1][#Branch1][O]"}]
