C. Loutelier et al., CONJUGATION REACTIONS OF CYCLODEPSIPEPTIDE TO GLUTATHIONYL ADDUCTS BYDIRECT IN-BEAM SYNTHESIS UNDER NEGATIVE-ION FAST-ATOM-BOMBARDMENT CONDITIONS, Rapid communications in mass spectrometry, 8(10), 1994, pp. 844-848
The conjugation products of E-destruxin (cyclodepsipeptide) with gluta
thione have been identified by fast-atom bombardment mass spectrometry
. Appropriate conditions were developed for cyclodepsipeptide substrat
e, which enabled the direct, dynamic mass spectra analysis of spontane
ous as well as glutathione-s-transferase catalyzed conjugation reactio
ns. Application to the most active cyclopeptide in the series of destr
uxins yielded glutathionyl adduct.
