Task: Please create a text description for a molecule.
Molecule SMILES: CO[C@@]1(NC(=O)CCC[C@@H](N)C(=O)O)C(=O)N2C(C(=O)O)=C(COC(N)=O)CS[C@@H]21
Constraint: Answer the question with full sentences.
Result: The molecule is one of three naturally occurring cephamycin antibiotics, differing from the A and B forms in its carbamoyloxymethyl substituent at C-3.
