User: I have a question about the molecule with SMILES CCC1NC(=O)[C@@H](NC(=O)c2ncccc2O)[C@@H](C)OC(=O)[C@H](c2ccccc2)NC(=O)[C@@H]2CC(=O)[C@H](CS[C@@H]3CN4CCC3CC4)CN2C(=O)[C@H](Cc2ccc(N(C)C)cc2)N(C)C(=O)[C@@H]2CCCN2C1=O.
Assistant: How can I help?
User: Please describe this drug.
Assistant: The answer is Quinupristin is a semi-synthetic derivative of pristinamycin, a natural occurring type B streptogramin. Quinupristin binds to the bacterial 50S ribosomal subunit, thereby inhibiting peptide chain elongation, and causing early termination of normal bacterial protein synthesis. Quinupristin is primarily effective against gram-positive cocci.
