[C][P][=Branch1][C][=O][Branch1][=Branch2][C][=C][C][NH2+1][C][C][Ring1][=Branch1][O-1]"}, {"from": "gpt", "value": "The molecule is a selective antagonist of GABAC receptors (also known as GABA-\u03c1 or GABAA-\u03c1 receptors). GABAC receptors are found primarily in the retina, although they may be present in other tissues, including the hippocampus, spinal cord, superior colliculus, pituitary and the gut. TPMPA is used as a pharmacological probe for the investigation of GABAC receptor function."}]
