Complete NMR characterization data have been measured for a series of fortimicin antibiotics, including the diamino-inositol component fortamine, fortimicins A, B, E, and isofortimicin. The data are comprised of 1D H-1 and C-13 NMR spectra, 1D H-1/N-15 HSQMBC, and 2D COSY, TOCSY, HSQC, and HMBC spectra. These data sets are under analysis. The 2D COSY and TOCSY are homonuclear H-1/H-1 data sets and are expected to confirm the H-1 NMR assignments. The 2D HSQC and HMBC spectra are heteronuclear H-1/C-13 data sets for confirmation of the C-13 assignments, while the 1D H-1/N-15 HSQMBC heteronuclear spectra contain information on the H-1/N-15 coupling constants.

已经测量了一系列Fortimicin抗生素的完整NMR表征数据，包括Diamino-氨基醇成分Fortamine，Fortimicins A，B，E和同二吡啶。数据包括1D H-1和C-13 NMR光谱，1D H-1/N-15 HSQMBC，以及2D COZY，TOCSY，HSQC和HMBC光谱。这些数据集正在分析中。 2D COZY和TOCSY是同核H-1/H-1数据集，并有望确认H-1 NMR分配。 2D HSQC和HMBC光谱是用于确认C-13分配的异核H-1/C-13数据集，而1D H-1/N-15 HSQMBC异核光谱包含有关H-1/N-15偶联常数的信息。
