User: I want to know more about the chemical with SMILES C(=N/NC1=NCCN1)\c1c2ccccc2c(/C=N/NC2=NCCN2)c2ccccc12.
Assistant: Sure, what is your question?
User: Please describe this drug.
Assistant: The answer is Bisantrene is an anthracenyl bishydrazone with antineoplastic activity. Bisantrene intercalates with and disrupts the configuration of DNA, resulting in DNA single-strand breaks, DNA-protein crosslinking, and inhibition of DNA replication.  This agent is similar to doxorubicin in activity, but unlike doxorubicin, does not exhibit cardiotoxicity. (NCI04)
