Abstract
The dalbaheptide antibiotic INA 9301 was isolated from a culture of Amycolatopsis orientalis. By using a combination of mass spectrometry and NMR spectroscopy, INA 9301 was assessed as N,N-dimethylvancomycin. Detailed 13C NMR characteristics of INA9301 in D2O and DMSO-d 6 are presented, together with 2D 1H-1H ROESY and 1H-13C gHMBC data, which confirmed the configurations of the asymmetric centers and spatial conformational shape of the molecule in aqueous solution.
