Studies on the synthesis and the antimicrobial and antioxidant activities of a novel class of fluorescein-based glycosides
摘要:
Facile glycosylation of a fluorescein diol derivative with per-O-acetylibenzoyl sugar derivatives using BF3 center dot Et2O catalyst resulted in the formation of the expected glycosides in 54-66% yield. The biological screening of the glycosides against different microbes shows good inhibitory activity. The antioxidant activity of the fluorescein-based glycosides shows remarkable inhibition (IC50 similar to 80%). (C) 2011 Elsevier Ltd. All rights reserved.
