[{"from": "human", "value": "Create a molecule that satisfies the conditions outlined in the description. The molecule is the hydrobromide salt form of pibrozelesin, a semisynthetic water-soluble derivative of the antineoplastic antibiotic duocarmycin B2, with antineoplastic activity. Activated by carboxyl esterase, pibrozelesin alkylates DNA by binding to adenine-thymine (A-T)-rich sequences in the minor groove of DNA, thereby inhibiting DNA replication and inducing apoptosis."}, {"from": "gpt", "value": "[C][C][=C][Branch2][=Branch1][Branch2][C][=C][C@@H1][Branch2][Branch1][S][C][N][Branch2][Ring1][=C][C][Ring1][Branch1][=C][C][=Branch1][#Branch1][=C][Ring1][=Branch2][N][Ring1][N][O][C][=Branch1][C][=O][N][C][C][N][Branch1][Branch1][C][C][Ring1][=Branch1][C][C][=Branch1][C][=O][C][=C][C][=C][C][=Branch1][P][=C][Branch1][N][C][=Branch1][#Branch1][=C][Ring1][=Branch1][N][Ring1][=Branch2][O][C][O][C][O][C][C][Br][C][=Branch1][C][=O][O][C].[Br]"}]
