Echinacea preparations are widely used for common cold. Many consumers and healthcare professionals are not aware that products available under the term Echinacea may differ in their composition, due to the use of different species, plant parts, extraction methods and addition of other components. In 2005, a Cochrane review has been published to provide(More)
Agonists of the nuclear receptor PPARγ are therapeutically used to combat hyperglycaemia associated with the metabolic syndrome and type 2 diabetes. In spite of being effective in normalization of blood glucose levels, the currently used PPARγ agonists from the thiazolidinedione type have serious side effects, making the discovery of novel ligands highly(More)
Alkamides are the major lipophilic constituents of ECHINACEA preparations, which are widely used in some European countries and in North America for common colds. In earlier investigations they have been shown to possess stimulatory effects on phagocytosis. Recent experiments have demonstrated that alkamides are detectable in human blood in relevant(More)
The antimalarial artemisinin derivatives artesunate (ART), arteether (ARE), and artemether (ARM) reveal remarkable antineoplastic activity. In the present investigation, we identified mRNA expression profiles associated with the response of tumor cells to ART, ARE, and ARM. We performed correlation and hierarchical cluster analyses of inhibition(More)
Medicinal plants have historically proven their value as a source of molecules with therapeutic potential, and nowadays still represent an important pool for the identification of novel drug leads. In the past decades, pharmaceutical industry focused mainly on libraries of synthetic compounds as drug discovery source. They are comparably easy to produce and(More)
BACKGROUND Echinacea has been widely used as an herbal remedy for the common cold, but efficacy studies have produced conflicting results, and there are a variety of echinacea products on the market with different phytochemical compositions. We evaluated the effect of chemically defined extracts from Echinacea angustifolia roots on rhinovirus infection. (More)
Alkamides are the major lipophilic constituents of Echinacea angustifolia roots. Due to their structural similarity with anandamide, we have evaluated their ability to bind to rodent cannabinoid receptors CB1 and CB2 by a standard receptor binding assay using [(3)H]CP-55,940 as a radioligand. The alkamides exhibited selective affinity especially to CB2(More)
Advances in understanding the physiology and pharmacology of the endogenous cannabinoid system have potentiated the interest of cannabinoid receptors as potential therapeutic targets. Cannabinoids have been shown to modulate a variety of immune cell functions and have therapeutic implications on central nervous system (CNS) inflammation, chronic(More)
AIM OF THE STUDY For the assessment of the in vitro anti-protozoal potential of plants traditionally used in Ecuador in the treatment of leishmaniasis, a combined approach based on interviews with healers as well as a literature search was carried out. MATERIALS AND METHODS From three regions of Ecuador, 256 local healers called "Agents of Traditional(More)
