BACKGROUND The aim of this experimental study was to investigate the role of apigenin in liver apoptosis, in an experimental model of hepatic ischemia-reperfusion in rats. MATERIALS AND METHODS Forty-eight Wistar rats (apigenin and control groups), 14 to 16 weeks old and weighing 220 to 350 g, were used. They were all subjected to hepatic ischemia by occlusion of the hepatic artery and portal...
Two series of apigenin [5,7-dihydroxy-2-(4-hydroxyphenyl)-4H-chromen-4-one] derivatives, 3a-3j and 4a-4j, were synthesized. The apigenin and alkyl amines moieties of these compounds were separated by C₂ or C₃ spacers, respectively. The chemical structures of the apigenin derivatives were confirmed using ¹H-NMR, ¹³C-NMR, and electrospray ionization mass spectroscopy. The in vitro antibacterial a...
Alzheimer's disease (AD) is one of the most prevalent neurodegenerative diseases, yet current therapeutic treatments are inadequate due to a complex disease pathogenesis. The plant polyphenol apigenin has been shown to have anti-inflammatory and neuroprotective properties in a number of cell and animal models; however a comprehensive assessment has not been performed in a human model of AD. Her...
Two flavones, apigenin and tangeretin, were studied for their ability to modulate gap junctional intercellular communication (GJIC) in the rat liver epithelial cell line REL. Their cytotoxicity was first determined by cell density and neutral red uptake assays: neither apigenin nor tangeretin are cytotoxic at 10 and 25 microM, the concentrations used in our experiments. We then studied GJIC usi...
Mortality associated with breast cancer is attributable to aggressive metastasis, to which TNFα plays a central orchestrating role. TNFα acts on breast tumor TNF receptors evoking the release of chemotactic proteins (e.g. MCP-1/CCL2). These proteins direct inward infiltration/migration of tumor-associated macrophages (TAMs), tumor-associated neutrophils (TANs), myeloid-derived suppressor cells ...
Recent studies involving phytochemical polyphenolic compounds have suggested flavones often exert pro-oxidative effect in vitro against wide array of cancer cell lines. The aim of this study was to evaluate the in-vitro pro-oxidative activity of apigenin, a plant based flavone against colorectal cancer cell lines and investigate cumulative effect on long term exposure. In the present study, tre...
The bark, leaves, and flowers of Paulownia trees have been used in traditional Chinese medicine to treat infectious and inflammatory diseases. We investigated the antiviral effects of Paulownia tomentosa flowers, an herbal medicine used in some provinces of P. R. China for the treatment of skin rashes and blisters. Dried flowers of P. tomentosa were extracted with methanol and tested for antivi...
The flavones apigenin (4',5,7,-trihydroxyflavone) and luteolin (3',4',5,7,-tetrahydroxyflavone) are plant secondary metabolites with antioxidant, antiinflammatory, and anticancer activities. We evaluated their impact on cell signaling pathways related to insulin-resistance and type 2 diabetes. Apigenin and luteolin were identified in our U-2 OS (human osteosarcoma) cell screening assay for micr...
Background: Doxorubicin has been used in the treatment of malignancies, including lymphoma, leukemia and breast cancer. Cardiotoxicity is the main adverse effect of doxorubicin. Apigenin, as a flavonoid, has antioxidant, anti-inflammatory and anti tumoral properties. The aim of this study is the assessment of the effect of apigenin on cardiotoxicity induced by doxorubicin. Materials and Method...
Introduction: Cognitive dysfunction is the most common problem of patients with Alzheimer disease (AD). The pathological mechanism of cognitive impairment in AD may contribute to neuronal loss, synaptic dysfunction, and alteration in neurotransmitters receptors. Mitochondrial synapses dysfunction due to the accumulation of amyloid beta (Aβ) is one of the earliest pathological features of AD. Th...
