Sugar-based bactericides targeting phosphatidylethanolamine-enriched membranes
Dias, Catarina; Pais, João P.; Nunes, Rafael; Blázquez-Sánchez, Maria-Teresa; Marquês, Joaquim T.; Almeida, Andreia F.; Serra, Patrícia; Xavier, Nuno M.Anthrax is an infectious disease caused by Bacillus anthracis, a bioterrorism agent that develops resistance to clinically used antibiotics. Therefore, alternative mechanisms of action remain a challenge. Herein, we disclose deoxy glycosides responsible for specific carbohydrate-phospholipid interactions, causing phosphatidylethanolamine lamellar-to-inverted hexagonal phase transition and acting over B. anthrac...
Synthesis of new sugar derivatives containing an α, β-unsaturated carbonyl syst...
Xavier, Nuno M.This PhD research work was focused on the synthesis and uses of bicyclic carbohydrate lactones, in the context of the access to new sugar derivatives containing an α,β- unsaturated carbonyl function. These molecular targets, chosen for the intrinsic bioactivity associated to the conjugated carbonyl system, were synthesized and submitted to biological evaluation, particularly their effect towards fungi and bacte...
