[{"from": "human", "value": "Create a molecule with the structure as the one described. The molecule is a derivative of adenosine in which the 5'-hydroxymethyl group is replaced by N-ethylcarboxamido and one of the hydrogens of the exocyclic amino function is substituted by a 3-iodobenzyl group. It has a role as an adenosine A3 receptor agonist. It is a member of adenosines, an organoiodine compound and a monocarboxylic acid amide. It is functionally related to an adenosine."}, {"from": "gpt", "value": "[C][N][C][=Branch1][C][=O][C@@H1][C@H1][Branch2][Ring2][Branch2][C@H1][Branch2][Ring2][Ring1][C@@H1][Branch1][Ring2][O][Ring1][Branch1][N][C][=N][C][=C][Branch1][=Branch2][N][=C][N][=C][Ring1][=Branch1][Ring1][=Branch2][N][C][C][=C][C][=Branch1][=Branch1][=C][C][=C][Ring1][=Branch1][I][O][O]"}]
