Chemistry of bleomycin. XVIII. Carbon-13 NMR studies.

Abstract

During chemical studies of bleomycin, many fragments and derivatives have been isolated and characterized. The 13C-NMR spectra of these compounds were taken and analyzed for structural information, and the complete assignment of the spectra was achieved. The 13C-chemical shift map thus obtained contains information about the structure and conformation and will be useful for studies on the chemistry and biology of bleomycin and related compounds.
