AGROPINE: A REVISED STRUCTURE

Article abstract of DOI:10.1016/S0008-6215(00)82224-7

The product known as agropine from crown-gall tumour is shown to be indistinguishable in all of its properties ( physical, chemical, and biological) from N²-(1'-deoxy-D-mannitol-1'-yl)-L-glutamine, 1,2'-lactone, a C₁₁H₂₀N₂O₇ compound produced by cyclisation of N²-(1'-deoxy-D-mannitol-1'-yl)-L-glutamine.Two prior assignments of a C₁₁H₁₇NO₇ formula obtained by high-resolution electronimpact mass spectrometry have been shown by field-desorption mass spectrometry to correspond to a fragment produced by the rapid loss of ammonia from the parent molecular species.
