[{"from": "human", "value": "Synthesize a molecule that matches the given characteristics. The molecule is an orally bioavailable, small-molecule, tryptophan hydroxylase (TPH) inhibitor prodrug, with potential antiserotonergic activity. Upon administration, telotristat etiprate is converted to its active moiety, telotristat (LP-778902), which binds to and blocks the activity of TPH. This may result in a reduction in peripheral serotonin (5-HT) production and improvement of serotonin-mediated gastrointestinal effects such as severe diarrhea. TPH, the rate-limiting enzyme in serotonin biosynthesis, is overexpressed in carcinoid tumor cells."}, {"from": "gpt", "value": "[C][C][O][C][=Branch1][C][=O][C@H1][Branch2][Branch1][=N][C][C][=C][C][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][C][=C][C][=Branch1][=Branch2][=N][C][=Branch1][Ring2][=N][Ring1][=Branch1][N][O][C@H1][Branch2][Ring1][Branch2][C][=C][Branch1][#Branch2][C][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][Cl][N][C][=C][C][=Branch1][Ring2][=N][Ring1][Branch1][C][C][Branch1][C][F][Branch1][C][F][F][N].[C][=C][C][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][C][=Branch1][C][=O][N][C][C][=Branch1][C][=O][O]"}]
