Synthesis and vasorelaxant and platelet antiaggregatory activities of a new series of 6-Halo-3-phenylcoumarins
(MDPI, 2010)A series of 6-halo-3-hydroxyphenylcoumarins (resveratrol-coumarins hybrid derivatives) was synthesized in good yields by a Perkin reaction followed by hydrolysis. The new compounds were evaluated for their vasorelaxant ... -
Improving the solubility of the antichagasic drug benznidazole through formation of inclusion complexes with cyclodextrins
(Sociedade Brasileira de Química, 2011)This study describes unpublished research on improving the solubility of benznidazole by the formation of an inclusion complex. The cyclodextrins selected were αCD, βCD, γCD, HPβCD, RMβCD and SBβCD. All complexes were ... -
Ionic and Polyampholyte N-Isopropylacrylamide-Based Hydrogels Prepared in the Presence of Imprinting Ligands: Stimuli-Responsiveness and Adsorption/Release Properties
(MDPI, 2011)The conformation of the imprinted pockets in stimulus-responsive networks can be notably altered when the stimulus causes a volume phase transition. Such a tunable affinity for the template molecule finds interesting ... -
Benzopyran-2-ones as attractive scaffold for MAO inhibitors: synthesis, biological evaluation and docking studies
(MDPI, 2011)Neurodegenerative diseases are becoming prevalent pathologies in developed societies due to increasing average of life expectancy of the population. This fact has encouraged an active research in the development of new ... -
Synthesis of new phthalazinedione derivatives
(MDPI, 2011)In the past few decades, the synthesis of new heterocyclic compounds has been a subject of great interest due to their wide applicability. Among a large variety of heterocyclic compounds, heterocycles containing phthalazine ... -
New Gastropod Vectors and Tetrodotoxin Potential Expansion in Temperate Waters of the Atlantic Ocean
(MDPI, 2012)Tetrodotoxin is a potent low weight marine toxin found in warm waters, especially of the Indian and Pacific Oceans. Intoxications are usually linked to the consumption of the puffer fish, although TTX was already detected ... -
Exploring the efficiency of gallic acid-based dendrimers and their block copolymers with PEG as gene carriers
(Future Science, 2012-07-20)The synthesis of a new family of amino-functionalized gallic acid-triethylene glycol (GATG) dendrimers and their block copolymers with polyethylene glycol (PEG) has recently being disclosed. In addition, these dendrimers ... -
New Invertebrate Vectors for PST, Spirolides and Okadaic Acid in the North Atlantic
(MDPI, 2013)The prevalence of poisoning events due to harmful algal blooms (HABs) has declined during the last two decades through monitoring programs and legislation, implemented mainly for bivalves. However, new toxin vectors and ... -
A Polymer/Oil Based Nanovaccine as a Single-Dose Immunization Approach
(PLOS, 2013)The recognized necessity for new antigen delivery carriers with the capacity to boost, modulate and prolong neutralizing immune responses prompted our approach, in which we describe a multifunctional nanocarrier consisting ... -
Oral Toxicity of Okadaic Acid in Mice: Study of Lethality, Organ Damage, Distribution and Effects on Detoxifying Gene Expression
(MDPI, 2013)In vivo, after administration by gavage to mice and rats, okadaic acid has been reported to produce lesions in liver, small intestine and forestomach. Because several reports differ in the damage detected in different ... -
Surface Plasmon Resonance Biosensor Method for Palytoxin Detection Based on Na+,K+-ATPase Affinity
(MDPI, 2013)Palytoxin (PLTX), produced by dinoflagellates from the genus Ostreopsis was first discovered, isolated, and purified from zoanthids belonging to the genus Palythoa. The detection of this toxin in contaminated shellfish is ... -
Crambescidin-816 Acts as a Fungicidal with More Potency than Crambescidin-800 and -830, Inducing Cell Cycle Arrest, Increased Cell Size and Apoptosis in Saccharomyces cerevisiae
(MDPI, 2013)In this paper, we show the effect of crambescidin-816, -800, and -830 on Saccharomyces cerevisiae viability. We determined that, of the three molecules tested, crambescidin-816 was the most potent. Based on this result, ... -
