Angolamycin (1) and two novel analogues (2 and 3) were isolated from the culture broth of a Streptomyces strain. NMR and MS analysis proved that 2 is the 18-dihydro-, while 3 is the 18-deoxo-18-dihydro derivative of angolamycin. Full experimental assignment of the 1H and the 13C NMR spectra of these compounds was obtained from 1D and 2D chemical shift(More)
A thin-layer chromatographic method has been developed for the detection of major nebramycin components, for the separation of tobramycin from other components and for studying the hydrolysis of carbamoyl derivatives and procedures for isolation and purification. A sensitive method has also been established for the detection of kanamycin B in tobramycin and(More)
