[{"from": "human", "value": "Based on the given information, design a molecule that meets the desired specifications. The molecule is an N-substituted cadaverine that is cadaverine in which one of the amino groups has been converted to the corresponding acetamide. It has a role as a human metabolite. It is a secondary carboxamide, a primary amino compound, a member of acetamides and a N-substituted cadaverine. It is functionally related to a cadaverine. It is a conjugate base of a N-acetylcadaverine(1+)."}, {"from": "gpt", "value": "[C][C][=Branch1][C][=O][N][C][C][C][C][C][N]"}]
