[C][C][=Branch1][Branch2][=N][N][=C][Branch1][C][N][N][C][=N][N][=C][Branch1][C][N][N].[Cl].[Cl]"}, {"from": "gpt", "value": "The molecule is the hydrochloride salt of a guanylhydrazone with potential antineoplastic activity. Mitoguazone competitively inhibits S-adenosyl-L-methionine decarboxylase (SAMD), an enzyme involved in the synthesis of polyamines, resulting in decreased proliferation of tumor cells, antimitochondrial effects, and p53-independent apoptosis. Polyamines, specifically spermine and spermidine, are essential for thymidine kinase production, DNA synthesis, and cell proliferation."}]
