Erythromycin A (EryA) was studied by electrospray ionisation tandem mass spectrometry (ESI-MS/MS) with the aim of developing a methodology for the structural elucidation of novel erythromycins developed by biological synthetic methods. Skimmer dissociation along with sequential mass spectrometry stu

Erythromycin A (EryA), sec-butyl erythromycin B (SEryB), oleandomycin (Olean) and a synthetic derivative, roxithromycin (Rox), were used to investigate the fragmentation of polyketide macrolide antibiotics by collision induced dissociation (CID) tandem mass spectrometry (MS/MS). Analyses were perfor
The structural characterization of intact polysialogangliosides by electrospray-ionization mass spectrometry (ESIMS) and tandem mass spectrometry (MS/MS) is described. The negative-ion ESI mass spectra of gangliosides 1 such as a tetrasialoganglioside GQlb, showed molecularly related ions 2 with hig
