[{"from": "human", "value": "Create a molecule that satisfies the conditions outlined in the description. The molecule is a N-acylpiperidine that is piperidine substituted by a (1E,3E)-1-(1,3-benzodioxol-5-yl)-5-oxopenta-1,3-dien-5-yl group at the nitrogen atom. It is an alkaloid isolated from the plant Piper nigrum. It has a role as a NF-kappaB inhibitor, a plant metabolite, a food component and a human blood serum metabolite. It is a member of benzodioxoles, a N-acylpiperidine, a piperidine alkaloid and a tertiary carboxamide. It is functionally related to an (E,E)-piperic acid."}, {"from": "gpt", "value": "[C][C][C][N][Branch1][Branch1][C][C][Ring1][=Branch1][C][=Branch1][C][=O][/C][=C][/C][=C][/C][=C][C][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][O][C][O][Ring1][#Branch1]"}]
