Polyacetylene Glycosides: Isolation, Biological Activities and Synthesis

Abstract

Polyacetylene glycosides (PAGs) constitute a relatively small class of secondary metabolites characterized by the presence of a sugar unit anomerically connected to a polyacetylene. These compounds are found in fungi, seaweed, and more often in plants. PAGs exhibit a wide range of biological and pharmacological activities and, as a result, the literature of these compounds has grown exponentially in recent years.

Keywords: Polyacetylene glycosides; carbohydrates; natural products; polyynes; secondary metabolites.
