Task: Please answer the following question about the molecule with SMILES Cn1cc(NC(=O)c2cc(NC(=O)c3cc(NC(=O)c4ccc(N(CCCl)CCCl)cc4)cn3C)cn2C)cc1C(=O)NCCC(=N)N.
Request: Please describe this drug.
Result: Tallimustine is a benzoyl mustard derivative of the antiviral agent distamycin A with potential antineoplastic activity. Tallimustine selectively binds to A-T rich regions in the minor groove of DNA and alkylates at the N3 position of adenine in a highly sequence-specific manner. This prevents DNA replication, inhibits cellular proliferation and triggers apoptosis. Moreover, unlike other clinical nitrogen mustards, tallimustine does not carry out guanine-N7 alkylation in the major groove of DNA, which may lead to a high selectivity of action.
