Abstract

Sweetness & light! The glycosyloxyamine glycoside of calicheamicin was exploited to form neo-D-ribosides in one efficient chemoselective step. Assessment of the neoglycosides revealed only slight reductions in cytotoxicity or ability to cleave DNA compared to the parent aglycons. This study exposes a previously unrecognized method for efficient calicheamicin bioconjugation amenable to a wide range of cancer- selective targeting modalities.
