Amphimedosides A–C: Synthesis, Chemoselective Glycosylation, And Biological Evaluation
摘要:
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 IC50 values ranging from 3.0 mu M to greater than 100 mu M.
