RESUMO
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.

Enulosides, carbohydrate derivatives containing an α,ß-unsaturated carbonyl unit, were designed and obtained in high yields and isomeric purity. All synthesized compounds exhibited antitumoral activity in micromolar range against four tested tumor cells lines, being the best results observed for HL-60 cells. These compounds open new possibilities to prepare an array of more active, site-specific or selective antitumor agents. 2016 Elsevier Ltd. All rights reserved.
