The structure of sibirosamine — A new amino sugar from the antibiotic sibiromycin

  • 35 Accesses


1. It has been shown that the antitumoral antibiotic sibiromycin is a glycoside of a new amino sugar which has been called sibirosamine.

2. It has been established that sibirosamine is a 3-C-methyl-4-methylamino-4,6-dideoxyhexopyranose, i.e., a new amino sugar differing from all the amino sugars known hitherto by the branching of the carbon skeleton.
