Complete assignments of the 1H and 13C resonances of 40-epi-(N1-tetrazolyl)-rapamycin and revised 13C assignments for rapamycin.
Complete 1H and 13C assignments of 40-epi-(N1-tetrazolyl)-rapamycin (ABT-578) in DMSO-d6 were made using 1H, 13C, DQCOSY, ROESY, TOCSY, HSQC and HMBC spectra. Comparing the assignments with those of rapamycin showed that in the published 13C assignments of rapamycin in DMSO-d6 the shifts for C-12 and C-42 have been interchanged, as well as the shifts for C-1 and C-8.
