Fractionation of an anti-inflammatory extract from Cayaponia tayuya roots yielded two active compounds, identified as 23,24-dihydrocucurbitacin B (1) and cucurbitacin R (2). Both were evaluated for their anti-inflammatory activity on several experimental models of pain and inflammation. In addition,
Certain natural products, derived from medicinal plants, exhibit anti-inflammatory properties, but the mechanism of action of many remains unclear. Borrelia burgdorferi spirochetes are responsible for causing Lyme arthritis through activation of the Toll-like receptor (TLR) signaling pathway. In
Psoriasis is a common skin disease, of which pathogenesis involves the increase of inflammatory reaction in epidermal cells. In an attempt to find therapeutics for psoriasis, we found that cucurbitacin B has an inhibitory potential on imiquimod-induced inflammation of keratinocytes. Cucurbitacin B
Cucurbitacin IIb (CuIIb) is one of the major active compounds in Hemsleyadine tablets which have been used for clinical treatment of bacillary dysentery, enteritis and acute tonsilitis. However, its action mechanism has not been completely understood. This study aimed to explore the
Wilbrandia ebracteata is a medicinal plant from South America used in folk medicine for the treatment of chronic rheumatic diseases. We have shown that the high performance liquid chromatography-characterized (HPLC) dichloromethane fraction isolated from Wilbrandia ebracteata (WEDC) inhibits the
The aim of this study was to investigate the effects of cucurbitacin R on an experimental model of adjuvant-induced arthritis in rats. The treatment of arthritic rats with cucurbitacin R (1 mg/kg p.o. daily) modified the evolution of the clinical symptoms, whereas the histopathology of paws
Cucurbitacin B (CuB) is a triterpenoid that is widely distributed in the plant kingdom and has a variety of biological activities. However, the immunomodulatory and anti-inflammatory effects of CuB have not been well characterized. Therefore, in this study, we investigated the effects of CuB on
BACKGROUND
Citrullus colocynthis (L.) Schrad is an important medicinal plant belonging to the family Cucurbitaceae. Cucurbitacin E glucoside (1) was isolated from Citrullus colocynthis fruits. A novel mono-ester of cucurbitacin-E and cinnamyl and caffeoyl-β-D-glucoside (2 and 3) was synthesized by
BACKGROUND
In this study, the bioactive compound in Lagenaria breviflora Roberty responsible for its anti-inflammatory and analgesic activities was isolated and chemically characterized.
METHODS
Compounds in the whole fruit, bark, pulp and seed of L. breviflora were partitioned utilizing their
OBJECTIVE
Cucurbitacin E (CuE), a triterpenoid compound isolated from Cucurbitaceae plants, possesses a wide range of biological activities including anti-inflammatory properties. The present study aimed to investigate the anti-inflammatory effect of CuE and the underlying mechanism of
Increasing studies indicated that Cucurbitacin E (CuE), a compound isolated from Cucurbitaceae, has been shown anti-inflammatory effect. However, the effect of CuE on rheumatoid arthritis (RA) inflammatory response and its potential molecular mechanism are still unknown. In this study, we
The anti-inflammatory and antinociceptive actions of the CH2Cl2 extract and semipurified fraction (F-III) from roots of Wilbrandia ebracteata Cogn. have been investigated in rats and mice. The CH2Cl2 extract (1-10 mg/kg, i.p.; ID50 5 mg/kg) and (3-30 mg/kg, p.o.; ID50 15 mg/kg) inhibited, in a
Asthma is a chronic inflammatory disorder of airway affecting people from childhood to old age, and is characterized by airway epithelial dysfunction. Cucurbitacin E (CuE), a tetracyclic triterpene isolated from Cucurbitaceae plants, has been recently proved to exert anti-inflammation and immunology
The in vivo and in vitro mechanistic anti-inflammatory actions of cucurbitacin E (CE) (Citrullus lanatus var. citroides) were examined. The results showed that LPS/INF-γ increased NO production in RAW264.7 macrophages, whereas L-NAME and CE curtailed it. CE did not reveal any cytotoxicity on
The present study investigated the improving effect of cucurbitacin B on liver fibrosis induced by concanavalin A in mice and explored its possible mechanism. AST, ALT and TB were detected by kits. ELISA was performed to detect the levels of IL 5, IL 6, IL 13 and TNF-α in serum. Haematoxylin-eosin
