Several reports have indicated that nuclear factor-κB (NF-κB) is constitutively activated in a variety of cancer cells including hepatoma cells and plays a key role in their growth and survival. Dehydroxymethylepoxyquinomicin (DHMEQ) derived from the structure of an antibiotic epoxyquinomicin C is a novel NF-κB inhibitor. In the present study, we evaluated the effect of DHMEQ on the NF-κB activity in human hepatoma cells, Huh-7, HepG2 and Hep3B, and the anti-tumor effect of DHMEQ on these cells in vitro and in vivo. DHMEQ inhibited the steady-state transcriptional activity of NF-κB in all hepatoma cells. DHMEQ blocked the constitutive DNA-binding activity and TNF-α-mediated nuclear translocation of NF-κB in Huh-7 cells. DHMEQ (5-20 µg/ml) dose-dependently reduced the viable cell number of all hepatoma cells. DHMEQ (20 µg/ml) induced apoptosis in all hepatoma cells, especially in Hep3B cells, and cell-cycle arrest in Huh-7 and HepG2 cells. These effects were accompanied by downregulation ...

Insulin stimulated protein synthesis in L6 myoblasts but did not increase the labelling of DAG or the release of phosphocholine from phosphatidylcholine. The DAG lipase inhibitor, RHC 80267, more than doubled the amount of label appearing in DAG but did not stimulate protein synthesis. Even in the presence of the DAG lipase inhibitor insulin failed to have any effect on DAG labelling, and conversely RHC 80267 did not modify the insulin-induced increase in protein synthesis. These results suggest that endogenous DAG production is not involved in the stimulation of protein synthesis by insulin. However, exogenous diacylglycerols (1-oleoyl-2-acetyl glycerol and 1-stearoyl-2-arachidonoyl glycerol) both stimulated protein synthesis in L6 myoblasts. The efficacy of the former (arachidonatefree) DAG suggested that their action was by activation of protein kinase C rather than by arachidonate release and prostaglandin formation. Ibuprofen, an inhibitor of cyclo-oxygenase failed to block the effects of ...

Cyclohexanone oxime is used primarily as a captive intermediate in the synthesis of caprolactam for the production of polycaprolactam (Nylon-6) fibers and plastics and also in a variety of industrial applications. Cyclohexanone oxime was selected for study because of the potential for human exposure and the interest in oximes as a chemical class. Toxicity studies of cyclohexanone oxime (approximately 99% pure) were carried out in male and female B6C3F1 mice; the compound was administered in drinking water for 2 weeks or 13 weeks. In addition, the genetic toxicity of cyclohexanone oxime was evaluated by determining mutagenicity in Salmonella typhimurium and induction of chromosomal aberrations in cultured Chinese hamster ovary cells in vitro, with and without S9 activation. The frequency of micronucleated normochromatic erythrocytes in the bone marrow and peripheral blood of mice from the 13-week study was also determined.. In the 2-week study, groups of five male and five female mice were given ...

According to Regulation (EC) No. 1907/2006, Annex VIII, section 9.2.2.1, column 2, the study need not be conducted if the substance is highly insoluble in water or the substance is readily biodegradable. The water solubility of the test substance is 47 µg/L at 20 °C and is therefore classed as insoluble. Furthermore a Ready Biodegradability test shows 54.1% degradation after 28 days. Although this does not fulfill the minimum criteria set out by the OECD method, it does however indicate that the material achieved ,50 % within 30 days, highlighting its propensity for biodegradation. An inherent biodegradability test shows 80.5% degradation after 28 days, therefore it is considered that the material is inherently biodegradable and as such not persistent in environmentally significant conditions. Therefore given the poor solubility and propensity for biodegradation further studies are scientifically unjustified. ...

The hydrogenation of a number of unsaturated compounds containing carbon-oxygen bonds has been studied. In most cases the reactions were performed at 30C and one atmosphere pressure of hydrogen, over Adams platinum oxide catalyst, in 50ml. of a solvent, usually containing some acid. It has been concluded from the results obtained that :- (1). Hydrogenolysis of the carbon-oxygen bond is always prevalent when acid or acidified solvents are used with a substrate having a centre of unsaturation close to the carbon-oxygen link. Thus under these conditions phenols, benzyl alcohols, allylic alcohols and cyclohexanones cleave readily. Removal of the centre of unsaturation from the vicinity of the carbon-oxygen bond renders it less liable to hydrogenolysis, as shown by the considerably smaller cleavage of ?-phenyl ethyl alcohol. The kinetics of the hydrogenolysis of phenols and benzyl alcohols show marked similarities with the kinetics of the hydrogenolysis of the corresponding phenyl and benzyl ...

N2 - Xanthine oxidase (XO) is a key enzyme in purine metabolism with an important role in various pathologies. Several flavonoids have been reported for their capacity to inhibit this enzyme, and, for these compounds, the ability to adopt a planar 3D structure has been accepted as fundamental prerequisite for such activity. Here we report the in vitro investigation of a series of non-planar protoflavone derivatives as XO inhibitors, among which protoapigenone 1′-O-propargyl ether was found to be an efficient competitive inhibitor of the enzyme with an IC50 value of 3.61 μM, significantly (p ,0.001) stronger than the anti-gout drug allopurinol ...

Y1 - 1999/12/24. N2 - Cyclization of N-(2-aryl-2-cyclohexen-1-yl)trichloroacetamides by a copper catalyst was investigated. It is crucially important for successful cyclization under mild conditions that alkoxycarbonyl groups are introduced to the nitrogen atom of the N-allyltrichloroacetamides as well as that CuCl- (bipyridine) is used as the catalyst. Three compounds, N-(2-phenyl-2- cyclohexen-1-yl)-, N-[2-(3,4-dimethoxyphenyl)-2-cyclohexen-l-yl]-, and N-[2- (3,4-methylenedioxyphenyl)-2-cyclohexen-1-yl]trichloroacetamides, where the Cbz or MeO2C- group was attached to the nitrogen atom, were instantly converted to the corresponding trichlorinated cis-3a-aryloctahydroindol-2- ...
Isothiocyanates (ITCs), including benzyl isothiocyanate (BITC), phenethyl isothiocyanate (PEITC) and sulforaphane, compounds found in cruciferous vegetable, are highly effective in inducing cell cycle arrest and apoptosis in a variety of cancer cells and animal models. Although some studies indicate that ITC-induced reactive oxygen species (ROS) generation may underlie apoptosis induction, our recent studies show that covalent binding to target proteins may be an important event triggering apoptosis. In this study, we report that BITC and PEITC significantly inhibit proteasome activity in a variety of cell types. Further studies show that ITCs inhibit both the 26S and 20S proteasomes, presumably through direct binding, and that this inhibition is unrelated to either ROS generation or ITC-induced protein aggregation. The potency of ITC-induced proteasome inhibition correlates with the rapid accumulation of p53 (tumor suppressor) and IκB nuclear factor-kappaB (nuclear factor-kappaB inhibitor). ...
Cyclohexanone is an aliphatic cyclic ketone. Cyclohexanone derivatives have potent pharmacological activity in the treatment of a broad spectrum of medical conditions (Puetz et al., 2003). The cyclohexanone moiety constitutes an important structural feature in several anti-inflammatory, analgesic, local anesthetic and antihistaminic drugs (Rajveer et al., 2010). As part of our studies in this area (Fatima et al., 2013; Hema et al., 2006), we have undertaken a single-crystal structure determination of the title compound.. In the title compound, Fig. 1, the cyclohexene ring (C9-C14) adopts an envelope conformation with atom C13 as the flap: puckering parameters (Cremer & Pople, 1975) are Q = 0.464 (3) Å, θ = 52.3 (4) °, and ϕ = 232.2 (4) °. Its mean plane makes a dihedral angle of 7.20 (12)° with the benzene ring (C1-C6).. In the crystal, hydrogen bonded chains running along the a-axis direction are generated by connecting neighbouring molecules via C-H···O hydrogen bonds (Table 1 and ...
