Valtrate is a principle compound isolated from Valeriana jatamansi Jones, a traditional Chinese folk medicine originally used to treat various nervous disorders. Here, we found that valtrate exhibited significant anti-cancer activity in vitro, especially in human breast cancer cells, while displayed
Identification of novel chemotherapeutic agents from traditional medicines and elucidation of the molecular basis of their anticancer effects are critical and urgently needed for modern pharmacotherapy. We previously found that analogs of the compounds present in Valeriana jatamansi, a traditional
Hairy root cultures of Valeriana officinalis var. sambucifolia were established by infection of sterile plantlets with Agrobacterium rhizogenes strain R1601 The transformed roots were grown in 10 different, hormone-free liquid media and the isovaltrate, valtrate, didrovaltrate,
Valeriana glechomifolia is a plant species endemic to southern Brazil that accumulates valepotriates, which are terpene derivatives, in all of its organs. Valepotriates are the presumed sedative generic components of the pharmaceutically used species of Valeriana. The influence of various
BACKGROUND
Valepotriates (epoxy iridoid esters) represent an important group of constituents that contribute to pharmacological effects for the genus Valeriana. Storage and extraction of valepotriates is a demanding task, as these compounds are thermolabile and unstable: even when decomposition
Valtrate, DIA-valtrate, acevaltrate, 1-beta-acevaltrate and didrovaltrate have been quantitatively estimated by reversed-phase HPLC in the leaves, flowers, stems and roots of Valeriana glechomifolia Meyer, V. catharinensis Graebn., V. chamaedryfolia Cham. & Schltdl., V. eichleriana (C.A.Mull.)
Four new diene valepotriates, sorbifolivaltrates A-D ( 1- 4), and the known compounds isovaltrate ( 5), valtrate ( 6), seneciovaltrate ( 7), valtrate hydrine B3 ( 8), and valtrate hydrine B7 ( 9), have been isolated by bioassay-guided fractionation of the cytotoxic hexanes and methyl ethyl ketone
Different in vitro cultures of Valerianaceae were analysed for valepotriate content [(iso)valtrate, acevaltrate, didrovaltrate] in a study on properties of production in vitro (plant species, growth conditions, differentiation level, valepotriate content of the medium after growth). The in vitro
Nonalcoholic fatty liver disease (NAFLD) is a common risk factor for metabolic syndrome that increases the risk of future cardiovascular disease, stroke, and diabetes. Recently, autophagy has been proposed as a means to prevent NAFLD. We investigated whether substances with autophagy-inducing
Valepotriates are iridoids found in variable amounts in Valerianaceae and might be among the bioactive compounds which confer anxiolytic properties to the Valeriana species. On the other hand, unspecific cytotoxicity has also been described. Presently, however, no particular molecular target has
Ethnopharmacological relevance: For many centuries, Mexican Valerian (Valeriana edulis ssp. procera) has been an important plant in folk medicine. It has been considered useful to control epilepsy; however, electroencephalographic
The valepotriates isovaltrate and valtrate, and the essential oil compound valeranone caused a suppression of rhythmic contractions in a closed part of the guinea-pig ileum in-vivo. The same compounds and didrovaltrate relaxed potassium stimulated contractures and inhibited BaCl2 contractions in
