Task: Answer the following question about the molecule with SMILES CNC(=O)[C@@H](NC(=O)[C@H](CC(C)C)[C@H](O)C(=O)NO)C(C)(C)C.
Question: Please describe this drug.
Result: Marimastat is a secondary carboxamide resulting from the foraml condensation of the carboxy group of (2R)-2-[(1S)-1-hydroxy-2-(hydroxyamino)-2-oxoethyl]-4-methylpentanoic acid with the alpha-amino group of N,3-dimethyl-L-valinamide. It has a role as an antineoplastic agent and a matrix metalloproteinase inhibitor. It is a secondary carboxamide and a hydroxamic acid.
