The antiproliferative activities of several extracts from cultivated microalgae in France have been studied against bronchopulmonary and epithelial cell lines, respectively (A549, NSCLC-N6 and SRA… (More)
One new and eight previously described lupane-type metabolites were isolated for the first time from Acacia mellifera (Leguminosae). Based on spectral analyses, the structure of the new compound was… (More)
In this study, the antiproliferative activity of a crude extract isolated from Bifurcaria bifurcata (Velley) Ross, a common marine brown alga of the Atlantic shores of Europe, was investigated. Its… (More)
Three new pentacyclic triterpenoids: (20R)-3-oxolupan-30-al (1), (20S)-3-oxolupan-30-al (2) and (20R)-28-hydroxylupen-30-al-3-one (3), along with (20S)-3beta-hydroxylupan-30-al (4), the latter… (More)
Several extracts of Origanum dictamnus, an endemic plant of Greece growing only in the island of Crete and the bioassay-directed isolated ursolic acid, were tested in vitro against the P388 (murine… (More)
Despite our growing insight into carcinogenesis, treatment of tumors, especially nonsmall cell lung cancer (NSCLC), remains limited and it is urgent to develop strategies that target tumor cells and… (More)
Late endosomes are a major trafficking hub in the cell at the crossroads between endocytosis, autophagy, and degradation in lysosomes. Herein is disclosed the first small molecule allowing their… (More)
Two new pentacyclic triterpenoids, (20R) 3-oxolupane-30al (1), and (20S) 3-oxolupane-30al (2), along with six known metabolites; 30-hydroxylup-20 (29)-en-3-one (3), 30-hydroxylup20 (29)-en-3ß-ol (4),… (More)
A facile synthesis of the C4-substituted isoquinolines 5a-c and 6a-c is described. Commercially available 4-bromoisoquinoline is converted to the alpha,beta-unsaturated esters 8 and 10 on treatment… (More)
Non-small cell lung cancers remain difficult to treat and have a high death rate and poor 5-year survival. New therapeutic strategies are urgently needed, which should be more specific for the cancer… (More)
