[{"from": "human", "value": "Synthesize a molecule that matches the given characteristics. The molecule is an icosanoid anion resulting from the removal of a proton from the carboxy group of resolvin E1; major species at pH 7.3. It has a role as a human xenobiotic metabolite and an anti-inflammatory agent. It is an icosanoid anion, a hydroxy fatty acid anion, a long-chain fatty acid anion and a polyunsaturated fatty acid anion. It is a conjugate base of a resolvin E1."}, {"from": "gpt", "value": "[C][C][C@H1][Branch2][Ring1][=N][/C][=C][/C][=C][\\C][C@H1][Branch2][Ring1][Ring1][/C][=C][/C][=C][/C][=C][\\C@H1][Branch1][=Branch2][C][C][C][C][=Branch1][C][=O][O-1][O][O][O]"}]
