[{"from": "human", "value": "Generate a molecule based on this description. The molecule is a water-soluble prodrug of the cyanoguanidine compound GMX1778 with potential antineoplastic activity. In vivo, apoptosis inducer GMX1777 is rapidly converted into GMX1778 through hydrolytic cleavage of a carbonate ester bond. Although the exact mechanism of action has yet to be fully elucidated, GMX1778 appears to antagonize nuclear factor-kappa B (NF-kB) transcription, resulting in the induction of tumor cell apoptosis."}, {"from": "gpt", "value": "[C][O][C][C][O][C][C][O][C][C][O][C][C][O][C][=Branch1][C][=O][O][C][N+1][=C][C][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][N][C][=Branch2][Ring1][Ring2][=N][C][C][C][C][C][C][O][C][=C][C][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][Cl][N][C][#N].[Cl-1]"}]
