Cryptomoschatone D2 from Cryptocarya mandioccana: cytotoxicity against human cervical carcinoma cell lines
(Revista de Ciências Farmacêuticas Básica e Aplicada, 2009) [Artigo]
Among the substances isolated from Cryptocarya sp, some styrylpyrones, such as goniothalamin, demonstrate antiproliferative activity in a broad range of human cell lines. In the present study, we assessed the cytotoxicity ...
Improvement of Pro-Oxidant Capacity of Protocatechuic Acid by Esterification
(Plos One, 2014-10-23) [Artigo]
Pro-oxidant effects of phenolic compounds are usually correlated to the one-electron redox potential of the phenoxyl radicals. Here we demonstrated that, besides their oxidizability, hydrophobicity can also be a decisive ...

Alkyl caffeates as anti-helicobacter pylori and scavenger of oxidants produced by neutrophils
(Medicinal Chemistry, 2014-02-01) [Artigo]
Helicobacter pylori pathogenic action involves the colonization of the gastrointestinal tract and a large production of reactive oxygen species (ROS) by the neutrophils attracted to the site of infection. The aim of this ...
Caffeic Acid Phenethyl Ester: Consequences of Its Hydrophobicity in the Oxidative Functions and Cytokine Release by Leukocytes
(Evidence-based Complementary And Alternative Medicine, 2014-01-01) [Artigo]
Numerous anti-inflammatory properties have been attributed to caffeic acid phenethyl ester (CAPE), an active component of propolis. NADPH oxidases are multienzymatic complexes involved in many inflammatory diseases. Here, ...

Chemical and microbiological evaluation of the internal surfaces of aluminum tubes both unlined and lined with epoxi resin by means of the stereoscope and scanning electron microscope
(Brazilian Journal of Microbiology, 2001-12-01) [Artigo]
A superfície interna das bisnagas fabricadas com alumínio não revestido e revestido com resina epóxi, utilizadas para acondicionar cremes, pomadas, géis, etc., foram avaliadas quimicamente e por métodos microbiológicos ...
Salacia campestris root bark extract: peroxidase inhibition, antioxidant and antiradical profile
(Brazilian Journal of Pharmaceutical Sciences, 2009-01-01) [Artigo]
Reactive oxygen species (ROS) and free radical species have been implicated in initiating or accompanying many diseases in living organisms; there is thus, a continual need for antioxidants molecules to inactivate ROS/free ...
Flavonols from Pterogyne nitens and their evaluation as myeloperoxidase inhibitors
(Phytochemistry, 2008-05-01) [Artigo]
A myeloperoxidase inhibitory kaempferol derivative, namely pterogynoside (1), was isolated from fruits of Pterogyne nitens, along with six known flavonols, kaempferol, afzelin, kaempferitrin, quercetin, isoquercetrin and ...
