Cells sensitive to the cytocidal effect of tumor necrosis factor (TNF) were protected against this effect when growth in the presence of elevated concentrations of tryptophan. Several other indole derivatives also provided protection against TNF cytotoxicity. Most effective were indole itself and
A dietary carcinogen, 3-amino-1,4-dimethyl-5H-pyrido[4,3-b]indole (Trp-P-1) at 20 microM activates caspase-3-like proteases as an apoptotic marker in rat splenocytes. The present study demonstrated 100 microM Trp-P-1 induced necrosis with activation of caspase-3-like proteases. The activation in
N,N'-bis(diethylenetriamine pentaacetic acid)-3,3'-(benzylidene)-bis-(1H-indole-2-carbohydrazide) (bis-DTPA-BI) was radiolabeled with (99m)Tc(CO)(3). The resulting (99m)Tc(CO)(3)-bis-DTPA-BI was characterized (LC-MS) and evaluated as a potential SPECT tracer for imaging of necrosis in Wistar rats
The aim of the present study was to develop a (68)Ga labeled bis-DOTA derivative of benzylidene-bis-indole and compare the in vivo stability and biodistribution with that of the previously reported bis-DTPA derivate for in vivo imaging of necrosis using PET. Uptake of the tracer was evaluated in a
Potent and selective inhibitors of tumor necrosis factor-alpha converting enzyme (TACE) were discovered with several new heterocyclic P1' groups in conjunction with cyclic beta-amino hydroxamic acid scaffolds. Among them, the pyrazolopyridine provided the best overall profile when combined with
Opening of mitochondrial permeability transition pore and Ca2+ overload are main contributors to myocardial ischemia-reperfusion injury, which paradoxically causes a wide variety of myocardial damage. We investigated the protective role of a novel necrosis inhibitor (NecroX-7; NecX) against
Renal ischemia-reperfusion injury (IRI) is involved in multiple diseases, such as kidney transplantation or contrast-induced nephropathy, and leads to acute kidney injury. However, there are no pharmacological agents available to prevent IRI. In this study, we investigated the effects of necroX-7
Renal fibrosis is closely related to chronic inflammation and is under the control of epigenetic regulations. Because the signaling of transforming growth factor-β1 (TGF-β1) and tumor necrosis factor-α (TNF-α) play key roles in progression of renal fibrosis, dual blockade of TGF-β1 and TNF-α is
Nrf2 is a basic leucine zipper transcriptional activator essential for the coordinated transcriptional induction of phase-2 and antioxidant enzymes. Brassica vegetables contain phytochemicals including glucoraphanin, the precursor of sulforaphane (SFN) and glucobrassicin, the precursor of
The solution structure of the Escherichia coli-expressed extracellular domain, residues 12-172, of the human 55 kDa type I tumor necrosis factor receptor (TNFR) has been probed by Raman (514.5 nm) and ultraviolet-resonance Raman (244 nm) excitations. The Raman spectra have been collected from both
p38alpha Mitogen Activated Protein Kinase (MAP kinase) is an intracellular soluble serine threonine kinase. p38alpha kinase is activated in response to cellular stresses, growth factors and cytokines such as interleukin-1 (IL-1) and tumor necrosis factor alpha (TNF-alpha). The central role of
We have previously demonstrated super-induced expression of the Grin2c gene encoding the N-methyl-D-aspartate receptor 2C subunit during the process of liver enlargement induced by phenobarbital, clofibrate, piperonyl butoxide, or lead nitrate. In the present study, hepatic Grin2c gene expression
Isatin is an endogenous indole that is increased in stress, inhibits monoamine oxidase (MAO) B and improves bradykinesia and striatal dopamine levels in rat models of Parkinson's disease. Consequently, it has been suggested that isatin might be a possible treatment for Parkinson's disease although
The cytoprotective effect of the natural dietary constituent indole-3-carbinol (I-3-C) on carbon tetrachloride (CCl4) mediated hepatotoxicity in mice was examined. I-3-C pretreatment by gavage 1 hr prior to intraperitoneal injection of CCl4 produced a 63% decrease in CCl4-mediated centrolobular
A rapid route to a series of naphthoquinone-fused indole derivatives via irradiation in a modified commercial domestic microwave is reported. The desired products were produced in high yields and short reaction times. The naphthoquinone-fused indole derivatives were evaluated for their
