beta lapachone/inflammation

beta-Lapachone (LAPA) is a chemotherapeutic agent that can inhibit the expression of nitric oxide (NO) and inducible NO synthase (iNOS) in alveolar macrophages. No other information on the agent's anti-inflammatory activity has been reported. In the present study, we investigated the molecular

AMP-activated protein kinase (AMPK), a crucial regulator of energy metabolic homeostasis, is suggested to regulate inflammatory responses, but its precise mechanisms are not fully understood. It has been reported that pharmacological activation of AMPK induces heme oxygenase-1 (HO-1) expression.

Inflammation plays a significant role in the pathogenesis of chronic diseases. Inflammatory diseases such as bacterial diseases, Alzheimer's disease, rheumatoid arthritis, multiple sclerosis, and so on, impose huge costs on the health systems. On the other hand, some side effects have been reported

The clinical utility of cisplatin is limited by nephrotoxicity. Oh et al. report that β-lapachone prevents this nephrotoxicity but not cisplatin's cytotoxicity for cancers. In addition to its potential clinical importance, the beneficial effect of β-lapachone on cisplatin acute kidney injury may

β-Lapachone (β-LAPA), a natural product from the lapacho tree in South America, is a potential chemotherapeutic agent that exhibit a wide variety of pharmacological effects such as anti-virus, anti-parasitic, anti-cancer, and anti-inflammatory activities. In order to discover novel anti-inflammatory

OBJECTIVE The purpose of this study was to evaluate the anti-inflammatory and anti-arthritic activities of 3,4-dihydro-2,2-dimethyl-2H-naphthol[1,2-b]pyran-5,6-dione (β-lapachone; β-lap) and to elucidate its probable mode of action. METHODS Carrageenan-induced paw edema, cell migration evaluation

OBJECTIVE AMP-activated protein kinase (AMPK) is suggested to exert cytoprotective and anti-inflammatory effects in endothelial cells, but the precise mechanisms are not fully understood. It has been reported that pharmacological activation of AMPK induces endothelial heme oxygenase-1 (HO-1)

In this study, we investigated the effects of β-lapachone (β-lap) on the production of cytokines in C57BL/6 mice. The culture supernatants of splenocytes exposed to β-lap plus lipopolysaccharide or concanavalin A (Con A) were harvested to determine Th1 (tumor necrosis factor-α, interferon-γ,

Beta-lapachone, a plant product, has been shown to be a novel inhibitor of DNA topoisomerase. In this study, we performed experiments to examine the effects of beta-lapachone on lipopolysaccharide (LPS)-induced inducible nitric oxide (NO) synthase (iNOS) in rat alveolar macrophages and aortic rings.

β-Lapachone is a naturally occurring quinine, originally isolated from the bark of the lapacho tree (Tabebuia avellanedae) which is currently being evaluated in clinical trials for the treatment of cancer. In addition, recent investigations suggest its potential application for treatment of

β-lapachone, a major component in an ethanol extract of Tabebuia avellanedae bark, is a promising potential therapeutic drug for various tumors, including lung cancer, the leading cause of cancer-related deaths worldwide. In the first part of this study, we found that apoptotic cell death induced in

beta-lapachone, a quinone compound obtained from the bark of the lapacho tree (Tabebuia avellanedae), was reported to have anti-inflammatory and anti-cancer activities. In this study, we investigated novel functions of beta-lapachone in terms of anti-metastasis and anti-invasion abilities using

OBJECTIVE To investigate the ability of various topoisomerase I and II inhibitors to reverse the pro-survival effects of calcium pyrophosphate dihydrate (CPPD) crystals on human neutrophils, thereby identifying potential agents that may promote the resolution of neutrophil accumulation typical of

BACKGROUND β-Lapachone (β-LAP) is a natural naphthoquinone compound isolated from the lapacho tree (Tabebuia sp.), and it has been used for treatment of rheumatoid arthritis, infection, and cancer. In the present study, we investigated whether β-LAP has anti-inflammatory effects under in vitro and
