[{"from": "human", "value": "Based on the given information, design a molecule that meets the desired specifications. The molecule is a member of the class of 4-pyridones that is nygerone B in which the N-phenyl substituent has been fluorinated at the para position. It has been isolated from Aspergillus niger ATCC 1015. It has a role as an Aspergillus metabolite. It is a monocarboxylic acid amide, a member of 4-pyridones, a member of monofluorobenzenes and a biaryl. It is functionally related to a nygerone B."}, {"from": "gpt", "value": "[C][=C][C][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][C][C][=C][C][=Branch1][C][=O][C][=Branch1][S][=C][N][Ring1][#Branch1][C][=C][C][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][F][C][=Branch1][C][=O][N]"}]
