[{"from": "human", "value": "Design a molecule that meets the criteria outlined in the description. The molecule is the combination of an antineoplastic pyrimidine analogue (trifluridine) with an inhibitor of its metabolism (tipiracil) that is used in the therapy of refractory, metastatic colorectal cancer. Trifluridine/tipiracil is associated with a low rate of transient serum enzyme elevations during therapy, but has not been implicated in cases of clinically apparent acute liver injury with jaundice."}, {"from": "gpt", "value": "[C][C@@H1][Branch2][Ring1][P][C@H1][Branch2][Ring1][O][O][C@H1][Ring1][Branch1][N][C][=C][Branch1][#Branch2][C][=Branch1][C][=O][N][C][Ring1][#Branch1][=O][C][Branch1][C][F][Branch1][C][F][F][C][O][O]"}]
