[{"from": "human", "value": "Based on the given information, design a molecule that meets the desired specifications. The molecule is a hydroxypyridine that is pyridine substituted by 4-aminobutanoyl and hydroxy groups at positions 3 and 6, respectively. It is a metabolite of nornicotine produced by Shinella sp. strain HZN7. It has a role as a bacterial xenobiotic metabolite. It is a hydroxypyridine, an aromatic ketone and a primary amino compound. It is a conjugate base of a 6-hydroxy-pseudooxy-nornicotinium."}, {"from": "gpt", "value": "[C][=C][C][=Branch1][C][=O][N][C][=C][Ring1][#Branch1][C][=Branch1][C][=O][C][C][C][N]"}]
