Abstract |
Our research aims at understanding the chemical resistance mechanisms of durable woods against fungi. Our ultimate goal is to isolate and identify antifungal compounds from these woods that could be used for the treatment of human fungal diseases. We therefore screened highly durable Amazonian wood selected from technical databases [1] and demonstrated that bioactive secondary metabolites responsible of the natural durability of the woods [2] can also be used to treat mycoses. This screening has given a very high ... |

Abstract |
Comme les animaux, certaines plantes produisent de la chaleur. Leur température s'élève jusqu'à parfois 40 °C au-dessus de celle de l'air ambiant. Cette thermogenèse joue surtout un rôle dans les différentes étapes de la pollinisation. |

Formes, couleurs, odeurs… les mécanismes par lesquels les Aracées
attirent les pollinisateurs se sont tellement diversifiés qu’elles sont
devenues de passionnants “cas d’école” pour les évolutionnistes. Ils
commencent aujourd’hui à retracer cette histoire évolutive complexe où
les interactions avec les insectes ne se font pas toujours “au bénéfice de

Abstract |
The present work is part of the Agrocos EUFP7 project and aimed at identifying new promising plant species exhibiting agrochemical properties or cosmetic interest. French Guiana being one of the megadiverse area of the globe considering plant biodiversity, 300 plant parts from 64 families were collected for the project. Among the 600 extracts evaluated as antifungals against phytopathogens, insecticides against plant pests and herbicides, 10% revealed an interesting activity. 7 of these extracts, mostly from the Leguminosae family, are currently under investigation for isolation and evaluation of pure compounds. Concerning cosmetic activity, 8 extracts from 5 different families were selected for further study. These results may lead to the development of novel products headed to agrochemical and cosmetic industry. |

Abstract |
Psidium acutangulum Mart. ex DC is used exclusively by the Wayana Amerindians in French Guiana, more particularly for the treatment of malaria. To understand this specific use, we embarked upon evaluating the antimalarial and anti-inflammatory activities of this traditional remedy as prepared by the Amerindian users. The decoction exerted good antiplasmodial activity in vitro (IC50 4 µg/ml on P. falciparum FcB1) and in vivo (39.7% inhibition of P. berghei NK65 in the murine model at 2 × 150 µl/day), as well as a strong anti-inflammatory effect in vitro regarding IL-1β, IL-6 and IL-8. Fractionation of the ethyl acetate extract (IC50 < 1 µg/ml) led to the isolation of six pure compounds, two of them, guaijaverine and the new compound wayanine, being moderately active against P. falciparum FcB1 in vitro (IC50 5 – 7 µg/ml). Along with the absence of cytotoxicity of the decoction and pure compounds, these results support the traditional use of this plant. |
