title: PB-5266 A, B and C, new monobactams. II. Physico-chemical properties and chemical structures.
abstract: The chemical structures of three new monobactams, PB-5266 A, B and C, were elucidated by their physico-chemical properties and spectrometric studies. In contrast to previously described monobactams, they all possess a dehydroasparagine residue.
