Natural products have long been used worldwide as therapeutic agents, but it is only recently, in response to the new challenges posed by global population aging, that interest in research into potentially therapeutic natural products has reemerged. In this context, coumarins, chemical compounds
(E)-3-(4-chlorophenyl)-N-(7-hydroxy-6-methoxy-2-oxo-2H-chromen-3-yl) acrylamide (SC-III3), a newly synthesized derivative of scopoletin, was previously shown to reduce the viability of HepG2 cells and tumor growth of HepG2 xenograft mouse model. It induces the death of HepG2 cells by a way
Hypertriglyceridemia is an independent risk factor of cardiovascular diseases. It is caused by the imbalance between hepatic triglyceride production and peripheral removal. Lipoprotein lipase (LPL) plays a central role in the removal of plasma triglyceride. During the screening of possible
Forty-three deaths were recorded among pigs fed boiled cassava meal at a private piggery over a period of two years. There were signs of sudden death in some cases with blood exuding from the external nares, vomiting, muscular weakness and pain or reluctance to move, emaciation, and stunted growth.
The present study determined the anti-inflammatory activity of scopoletin in gout air pouch model and revealed the underlying mechanisms by in vitro assays. Monosodium urate (MSU) crystal-induced inflammation in mouse air pouch model, an experimental model for acute gout, was used to assess the
Scopoletin exists in nature as an anti-oxidant, hepatoprotective, and anti-inflammatory activities reagent. In this study, we have investigated the analgesic effects of the scopoletin using the models of acetic acid-induced writhing response and the formalin test, the anti-inflammatory effects of
Nicotiana tabacum Togt encodes a scopoletin glucosyltransferase (UDPglucose:scopoletin O -beta-D-glucosyltrans- ferase, EC 2.4.1.128) known to act in vitro on many different substrates including the 6-methoxy-7-hydroxy- coumarin scopoletin. This phenolic compound accumulates in vast amounts,
Scopoletin (6-methoxy-7-hydroxycoumarin) is a coumarin compound and a pharmacologically active agent that has been isolated from several plant species. However, as yet there is no clear explanation of how scopoletin affects the production of inflammatory cytokine. We therefore used cells from the
Hypertension is a disease of high prevalence and morbidity where vascular inflammation and associated oxidative stress (endothelial dysfunction) is the underlying cause of this pathology. We are reporting the antihypertensive activity of extracts and fractions of Malva parviflora in mice with
Irradiation of keratinocytes by ultraviolet B induces cytokine production, which in turn activates fibroblasts to produce cytokines and increase matrix metallopeptidase (MMP)‑1 protein expression. The present study investigated the effect and potential mechanisms of scopoletin on the regulation of
Adherent human mesangial cells (HMC) were unable to phagocytose serum-treated zymosan (STZ), nevertheless this stimulus (1 mg/ml) induced a marked immediate increase of H2O2 and O2- release at a rate of 3.15 +/- 0.35 and 3.40 +/- 0.12 nmol/10(6) HMC/hr, respectively. Zymosan alone resulted in no
The present study aimed to evaluate the protective effects of scopoletin (SC) on cerulein-induced acute pancreatitis (AP) and associated lung injury in mice.
Acute pancreatitis was induced in male Swiss mice by 6 consecutive hourly intraperitoneal injections of cerulein (50 μg/kg). Scopoletin was
An investigation of the aqueous ethanolic extract (AE) of the aerial parts of Torilis radiata Moench yielded two triterpenes (lupeol acetate (1) and α-amyrin (2)), a sterol (spinasterol (3)) from its n-hexane fraction (HF), a flavone (acacetin (4)), a coumarin (scopoletin (5)), a phenolic acid
We previously established that normal articular chondrocytes, like macrophages, express class II major histocompatibility antigens, present antigen, and induce mixed and autologous lymphocyte stimulation. In a recent study using the trapped indicator 2',7'-dichlorofluorescein diacetate, we were able
A sensitive peroxidase-dependent luminol-enhanced chemiluminescence (ECL) assay for determination of hydrogen peroxide (H2O2) generation by tumour cells was established. This test system allows determination of H2O2 in concentrations as low as 25 pmol (50 nmol/L) and yields results which are
