[{"from": "human", "value": "What can you tell me about this molecule? [C][N][Branch1][Ring2][C][C][Cl][C][C][Cl]"}, {"from": "gpt", "value": "The molecule is a nitrogen mustard and antineoplastic agent that has been in clinical use for more than 60 years, given systemically in combination with other antineoplastic agents to treat Hodgkin disease, chronic leukemias, lung cancer and polycythemia vera. Currently, however, it is used largely as a topical gel for therapy of cutaneous T-cell lymphomas and mycosis fungoides. Given parenterally in combination with other antineoplastic agents it was associated with low rates of serum enzyme elevations during therapy, but mechlorethamine has not been implicated specifically in cases of acute, clinically apparent injury."}]
