User: I want to know more about the compound with SMILES Cc1ccc(NC(=O)c2ccc(CN3CCN(C)CC3)cc2)cc1Nc1nccc(-c2cccnc2)n1.
Assistant: Interesting, how can I help?
User: Please describe this drug.
Assistant: The answer is Imatinib is an antineoplastic agent that inhibits the Bcr-Abl fusion protein tyrosine kinase, an abnormal enzyme produced by chronic myeloid leukemia cells that contain the Philadelphia chromosome.  Imatinib also inhibits the receptor tyrosine kinases for platelet-derived growth factor (PDGF) and stem cell factor (SCF)/c-kit; the SCF/c-kit receptor tyrosine kinase is activated in gastrointestinal stromal tumor (GIST).  This agent inhibits proliferation and induces apoptosis in cells that overexpress these oncoproteins.
