[C][=C][Branch1][=C][C][=Branch1][#Branch2][=C][C][=Branch1][Branch1][=C][Ring1][=Branch1][O][O][O][C][C][N]"}, {"from": "gpt", "value": "The molecule is an antagonist of the neurotransmitter dopamine with potential antineoplastic activity. 6-Hydroxydopamine (6-HOD) can be taken up by selective adrenergic terminals, thereby causing acute degeneration of adrenergic terminals that leads to depletion of norepinephrine, and of dopamine in the dopamine-sensitive sites. This agent is auto-oxidated at physiological pH that leads to the formation of reactive free radicals, thereby leading to cytotoxicity in neural cells.  6-Hydroxydopamine is often used to induce CNS and sympathetic neural lesions that model aging and various nervous disorders in animal systems."}]
