Abstract
The amphimedosides, discovered in 2006, are the first examples of naturally occurring glycosylated alkoxyamines. We report syntheses of amphimedosides A-C that feature a stereoselective oxyamine neoglycosylation and found that these alkaloids display modest cytotoxicity toward seven diverse human cancer cell lines, exhibiting IC(50) values ranging from 3.0 μM to greater than 100 μM.
