Leishmanicidal activity of Morita-Baylis-Hillman adducts.

Leishmaniasis is a neglected disease that affects millions of people, mostly in developing countries. Although this disease has a high impact on public health, there are few drug options to treat the different leishmaniasis forms. Additionally, these current therapies have various adverse effects, including gastrointestinal disturbances, headache, pancreatitis, and hepatotoxicity.

Tissue oxygenation in peripheral muscles and functional capacity in cystic fibrosis: a cross-sectional study.

New Findings: What is the central question of this study? How do peripheral muscle tissue oxygenation and physical conditioning levels of children and adolescents with cystic fibrosis compare to demographically matched controls? What is the main finding and its importance? Children and adolescents with cystic fibrosis consumed more oxygen, more quickly and exhibited slower recovery, demonstrating that there may have been deficiencies in oxygen supply related to both oxygen uptake and oxygen transport.

Abstract: Cystic fibrosis affects skeletal muscle performance and functional capacity. However, it is currently unclear how peripheral muscle behaviour is affected, especially in children and adolescents.

Synthesis and evaluation of the anti-nociceptive and anti-inflammatory activity of 4-aminoquinoline derivatives.

In this paper, we describe the synthesis and pharmacological evaluation of a series of 4-aminoquinolines. The compounds were characterised and tested in models of pain and inflammation, using the writhing test with acetic acid, formalin test, peritonitis test by zymosan and arthritis test with Freund's adjuvant complete assay. The results revealed that all of the 4-aminoquinolines that were prepared promoted anti-nociceptive activity as well as acute and chronic anti-inflammatory effects, with marked activity in the derivates labelled with BAQ and 7-CF3-MAQ.

Antinociceptive and anti-inflammatory effects of flavonoids PMT1 and PMT2 isolated from Piper montealegreanum Yuncker (Piperaceae) in mice.

In this study, we identified the antinociceptive and anti-inflammatory effects of two flavonoids (PMT1 and PMT2) from Piper montealegreanum. The antinociceptive effect was evaluated using the classical tests: acetic acid-induced writhing, formalin and hot plate test. PMT1 and PMT2 (0.
