[{"from": "human", "value": "Create a molecule with the structure as the one described. The molecule is only found in individuals that have used or taken this drug. It is an antineoplastic antibiotic produced by Streptomyces caespitosus. It is one of the bi- or tri-functional alkylating agents causing cross-linking of DNA and inhibition of DNA synthesis. Mitomycin is activated in vivo to a bifunctional and trifunctional alkylating agent. Binding to DNA leads to cross-linking and inhibition of DNA synthesis and function. Mitomycin is cell cycle phase-nonspecific."}, {"from": "gpt", "value": "[C][C][=C][Branch2][Ring2][Branch2][C][=Branch1][C][=O][C][=C][Branch1][Branch1][C][Ring1][#Branch1][=O][N][C][C@H1][C@@H1][Branch2][Ring1][C][C@@][Ring1][Branch1][Branch1][O][C@@H1][Ring1][#Branch2][C][O][C][=Branch1][C][=O][N][O][C][N][Ring1][N][N]"}]
