Polyoxypregnanes as safe, potent, and specific ABCB1-inhibitory pro-drugs to overcome multidrug resistance in cancer chemotherapy in vitro and in vivo

2021

Multidrug resistance (MDR) mediated by ATP binding cassette subfamily B member 1 (ABCB1) is significantly hindering effective cancer chemotherapy. However, currently, no ABCB1-inhibitory drugs have been approved to treat MDR cancer clinically, mainly due to the inhibitor specificity, toxicity, and drug interactions. Here, we reported that three polyoxypregnanes (POPs) as the most abundant constituents of Marsdenia tenacissima (M. tenacissima) were novel ABCB1-modulatory pro-drugs, which underwent intestinal microbiota-mediated biotransformation in vivo to generate active metabolites. The metabolites at non-toxic concentrations restored chemosensitivity in ABCB1-overexpressing cancer cells v…

La concepción del espacio-tiempo en la cosmología sarvāstivāda

2013

The present article focuses on the reconstruction of the cosmological models from the school of Kashmir (fourth century), as they are registered in the compendium of sarvāstivāda-vaibhāsika school, attributed to the Buddhist monk Vasubandhu and titled Abhidharmakośabhāsya. The articles identifies the different textual sources of the cosmological models and describes its general structure, based in three realms (sensible, subtle matter and immaterial). It analyzes the relevant characteristics of the concepts of Space and Time, discovering and unusual model in comparison with the contemporaries cosmologies from the Mediterranean.

De la parole aux actes dans la prise de décision : Analyse du lien entre les hymnes et la prise de décision dans le film "Des hommes et des dieux. »

2012

International audience; Axe Exemplarité, autorité et sacré ; pouvoir symbolique De la parole aux actes dans la prise de décision Analyse du lien entre les hymnes et la prise de décision dans le film Des hommes et des dieux Odile Riondet, MCF-HDR Rectorat de Lyon odile.riondet@wanadoo.fr La question de la prise de décision est centrale dans toute organisation. C'est sur une décision qu'une organisation peut jouer son avenir, sa pérennité, sa vie économique, mais aussi son image, sa fiabilité, sa réputation, son autorité, autrement dit sa vie symbolique. Entre ce qu'une organisation pose ou tente de poser (les mots de sa communication, de sa charte éthique) et sa manière de se conduire, les d…

Hairy Garlic (Allium subhirsutum) from Sicily (Italy): LC-DAD-MSn Analysis of Secondary Metabolites and In Vitro Biological Properties

2020

Allium subhirsutum, known as hairy garlic, is a bulbous plant widespread in the Mediterranean area and locally used as a food and spice. In the present study, the chemical profile of the ethanolic extracts from bulbs (BE) and aerial parts (APE) were analyzed by HPLC-ESI-MSn, and antioxidant properties were evaluated by DPPH, ABTS and TEAC assays. The traditional use in the diet, and the well documented biological activity of Allium species suggest a potential as a new nutraceutical. For this reason, the potential usefulness of this food can be considered in the treatment and prevention of degenerative Alzheimer disease. For this reason, acetylcholinesterase inhibitory property was investiga…
