[{"from": "human", "value": "Synthesize a molecule that matches the given characteristics. The molecule is only found in individuals that have used or taken this drug. It is a vasoconstrictor found in ergot of Central Europe. It is an alpha-1 selective adrenergic agonist and is commonly used in the treatment of migraine disorders. Ergotamine acts on migraine by one of two proposed mechanisms: 1) activation of 5-HT<sub>1D</sub> receptors located on intracranial blood vessels, including those on arterio-venous anastomoses, leads to vasoconstriction, which correlates with the relief of migraine headache, and 2) activation of 5-HT<sub>1D</sub> receptors on sensory nerve endings of the trigeminal system results in the inhibition of pro-inflammatory neuropeptide release."}, {"from": "gpt", "value": "[C][C@@][Branch2][Ring2][#Branch1][C][=Branch1][C][=O][N][C@H1][Branch2][Ring1][Branch1][C][=Branch1][C][=O][N][C][C][C][C@H1][Ring1][Branch1][C@@][Ring1][#Branch2][Branch1][Ring2][O][Ring1][=C][O][C][C][=C][C][=C][C][=C][Ring1][=Branch1][N][C][=Branch1][C][=O][C@H1][C][N][Branch2][Ring1][Branch2][C@@H1][C][C][=C][N][C][=C][C][=C][C][=Branch1][=Branch1][=C][Ring1][=Branch2][Ring1][=Branch1][C][Ring1][N][=C][Ring1][S][C]"}]
