[{"from": "human", "value": "Synthesize a molecule that matches the given characteristics. The molecule is a dibenzoxepin derivative and tricyclic antidepressant (TCA) with antipruritic, antidepressive and anxiolytic activities. Doxepin blocks the reuptake of norepinephrine and serotonin (5-HT) into presynaptic terminals thereby prolonging the availability of the monoaminergic neurotransmitters within the synaptic cleft and enhancing their neurotransmission. Doxepin also has antagonistic effects on histamine H1, 5-HT2, alpha-1 adrenergic, and muscarinic receptors. The antipruritic effect of this agent is mediated through inhibition of histamine receptors."}, {"from": "gpt", "value": "[C][N][Branch1][C][C][C][C][C][=C][C][=C][C][=C][C][=C][Ring1][=Branch1][C][O][C][=C][C][=C][C][=C][Ring1][=Branch1][Ring1][#C]"}]
