Five new (2, 3, 5, 7, and 9) and four known rotenoids (1, 4, 6, and 8) were isolated from a methanol extract of Boerhaavia diffusa roots. The structures of the new rotenoids were elucidated by spectroscopic data interpretation. The 70% ethanol extract, a rotenoid-rich fraction, and all isolated
BACKGROUND
Boerhavia diffusa L. (Nyctaginaceae) roots are used in Ayurveda for treating inflammatory diseases. Generally poor oral bioavailability is a major problem associated with herbal drugs.
OBJECTIVE
To develop a phospholipid complex of rotenoid-rich fraction (RRF) and evaluate its in vivo
OBJECTIVE
Deguelin is a natural rotenoid that shows anti-inflammatory and antimicrobial activities. Rotenoids prevent oxidative damage and potentiate natural antioxidant activity in diabetic conditions, suggesting utility in treating diabetes and its complications. Here, we evaluate the potential
Five structurally related rotenoids were isolated from the roots of Clitoria fairchildiana. The antiinflammatory activity was investigated using a capillary permeability assay. The protective effect was measured as the inhibition in vascular permeability produced by acetic acid in the peritoneal
The seeds of Clitoria fairchildiana provided a new rotenoid, 6-hydroxy-2,3,9-trimethoxy-[1]benzopyrano[3,4-b][1]benzopyran-12(6H)-one. The structural elucidation was performed using detailed analyses of H- and 13C-NMR spectra including 2DNMR spectroscopic techniques (1H-13CHETCOR) and by comparison
OBJECTIVE
Free radicals are implicated in the aetiology of some gastrointestinal disorders such as gastric ulcer, colorectal cancer and inflammatory bowel disease. In the present study we investigated the antioxidant and genoprotective activity of some rotenoids (i.e. boeravinones) isolated from the
Excessive bone resorption by osteoclasts (OCs) plays an important role in lytic bone diseases, such as osteoporosis. Although the pharmacological treatment of osteoporosis has been extensively developed, alternative treatments are still needed. Deguelin, a rotenoid isolated from several plant
A new isoflavone, 4'-gamma,gamma-dimethylallyloxy-5,7,2',5'-tetramethoxyisoflavone, brandisianin A (1), was isolated from the leaves of Millettia brandisiana, along with one synthetically known isoflavone, 7,4'-di-O-prenylgenistein (2) and twelve known compounds. The structures were elucidated on
The main goal of adequate organ preservation is to avoid further cellular metabolism during the phase of ischemia. However, modern preservation solutions do rarely achieve this target. In donor organs hypoxia and ischemia induce a broad spectrum of pathologic molecular mechanisms favoring primary
Among the several rotenoids, amorphigenin is isolated from the leaves of Amopha Fruticosa and it is known that has anti-proliferative effects and anti-cnacer effects in many cell types. The main aim of this study was to investigate the effects of amorphigenin on osteoclast differentiation in vitro
Several natural compounds, especially plant products and dietary constituents, are able to exhibit 'angiopreventive' (anti-angiogenic chemoprevention) activities both in vitro and in vivo. Deguelin is a rotenoid of the flavonoid family with chemopreventive activities able to decrease tumor incidence
BACKGROUND
The genus Boerhavia is widely distributed in tropical, subtropical and temperate regions of the world including Mexico, America, Africa, Asia, Indian Ocean Islands, Pacific Islands and Australia. The genus Boerhavia is extensively used by local peoples and medicinal practitioners for
The liver is the most important organ that plays an important role in maintaining various physiological processes in the body. Hepatitis is an inflammation of the liver and is characterized by the presence of inflammatory cells in the tissue of the organ. There are five main viruses, referred to as
