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...
Composition and in vitro antioxidants activity of Chamaerops Humilis L.
Coelho, Jose P.; Veiga, Jerson G.; Elvas-Leitao, Ruben; Brigas, Amadeu; Dias, Ana M.; Oliveira, Maria C.The aim of this work is to evaluate the polyphenols composition and the antioxidant activity of methanol extracts of Chamaerops humilis L. Methanol extracts from dried leaves of Chamaerops humilis were prepared using Soxhlet extraction and examined as potential sources of phenolic compounds. Different methods were used to evaluate antioxidant activity of the extracts, including colored (ABTS*+), DPPH radical sc...
