Question: Please describe this drug.
 The Chemical can be represented with the SMILES COc1cccc2c1C(=O)c1c(O)c3c(c(O)c1C2=O)C[C@@](O)(C(=O)CO)C[C@@H]3O[C@H]1C[C@H](N)[C@H](O[C@@H]2CCCCO2)[C@H](C)O1.
Answer: Pirarubicin is an analogue of the anthracycline antineoplastic antibiotic doxorubicin.  Pirarubicin intercalates into DNA and interacts with topoisomerase II, thereby inhibiting DNA replication and repair and RNA and protein synthesis.  This agent is less cardiotoxic than doxorubicin and exhibits activity against some doxorubicin-resistant cell lines. (NCI04)
