Synthesis, in vitro and in vivo anti-Trypanosoma cruzi and toxicological activi...
Almeida, Tamires Cunha; Ribeiro, Luis Henrique Gonzaga; Santos, Luiza Braga Ferreira dos; Silva, Cleiton Moreira da; Branquinho, Renata TupinambáChagas disease is a major health problem not only in Latin America but also in Europe and North America due to the spread of this disease into nonendemic areas. In terms of global burden, this major tropical infection is considered to be one of the most neglected diseases, and there are currently only two available chemotherapies: benznidazole and nifurtimox. Unfortunately, although these chemotherapies are ben...
Increased body exposure to new anti-trypanosomal through nanoencapsulation.
Branquinho, Renata Tupinambá; Lana, Gwenaelle Elza Nathalie Pound; Milagre, Matheus Marques; Guimarães, Dênia Antunes Saúde; Vilela, José Mário CarneiroLychnopholide, a lipophilic sesquiterpene lactone, is efficacious in mice at the acute and chronic phases of Chagas disease. Conventional poly-ε-caprolactone (PCL) and long-circulating poly(D,L-lactide)-block-polyethylene glycol (PLA-PEG) nanocapsules containing lychnopholide were developed and characterized. Lychnopholide presented high association efficiency (>90%) with the nanocapsules. A new, fast and simpl...
Biodegradable polymeric nanocapsules prevent cardiotoxicity of anti-trypanosoma...
Branquinho, Renata Tupinambá; Roy, Jérôme; Farah, Charlotte; Garcia, Giani Martins; Aimond, Franck; Guennec, Jean Yves LeChagas disease is a neglected parasitic disease caused by the protozoan Trypanosoma cruzi. New antitrypanosomal options are desirable to prevent complications, including a high rate of cardiomyopathy. Recently, a natural substance, lychnopholide, has shown therapeutic potential, especially when encapsulated in biodegradable polymeric nanocapsules. However, little is known regarding possible adverse effects of l...
Avaliação da eficácia de lactona sesquiterpênica nanoestruturada em modelo expe...
Branquinho, Renata TupinambáOs objetivos deste trabalho foram isolar desenvolver, caracterizar e validar formulações farmacêuticas nanoestruturadas (NC) com lactona sesquiterpênica (LS), licnofolida (LIC) obtida de Lychnophora trichocarpha com atividade anti- T.cruzi “in vitro”. Partes aéreas da planta foram coletadas e secadas e suas frações acetato de etila separadas em coluna cromatográfica de sílica gel até a obtenção da LIC pura. A L...
