[{"from": "human", "value": "Synthesize a molecule that matches the given characteristics. The molecule is a radioconjugate composed of PSMA-617, a human prostate-specific membrane antigen (PSMA)-targeting ligand, conjugated to the beta-emitting radioisotope lutetium Lu 177 (177Lu), with potential antineoplastic activity against PSMA-expressing tumor cells. Upon intravenous administration of lutetium Lu 177  vipivotide tetraxetan, vipivotide tetraxetan targets and binds to PSMA-expressing tumor cells. Upon binding, PSMA-expressing tumor cells are destroyed by 177Lu through the specific delivery of beta particle radiation. PSMA, a tumor-associated antigen and type II transmembrane protein, is expressed on the membrane of prostatic epithelial cells and overexpressed on prostate tumor cells."}, {"from": "gpt", "value": "[C][C][C][Branch2][Branch1][Ring2][C][C][C][Ring1][=Branch1][C][N][C][=Branch1][C][=O][C][N][C][C][N][Branch2][Ring1][O][C][C][N][Branch1][S][C][C][N][Branch1][Branch1][C][C][Ring1][N][C][C][=Branch1][C][=O][O-1][C][C][=Branch1][C][=O][O-1][C][C][=Branch1][C][=O][O-1][C][=Branch1][C][=O][N][C@@H1][Branch1][S][C][C][=C][C][=C][C][=C][C][=C][Ring1][=Branch1][C][=C][Ring1][#Branch2][C][=Branch1][C][=O][N][C][C][C][C][C@@H1][Branch1][=Branch1][C][=Branch1][C][=O][O][N][C][=Branch1][C][=O][N][C@@H1][Branch1][Branch2][C][C][C][=Branch1][C][=O][O][C][=Branch1][C][=O][O].[177Lu+3]"}]
