Perennial broadleaves such as dandelion (Taraxacum officinale G.H. Weber ex Wiggers) and white clover (Trifolium repens L.) are known to be pervasive weeds in stands of maintained turfgrasses. The use synthetic herbicides is the most common effective method control for these weeds. As pesticide European countries, Canada, United States becoming more scrutinized, identification alternative weed ...
Novel 4-(4-substituted phenyl)-5-(3,4,5-trimethoxy/3,4-dimethoxy)-benzoyl-3,4-dihydropyrimidine-2(1H)-one/thione derivatives (DHP1-9) were designed, synthesized, characterized and evaluated for antitumor activity against cancer stem cells. The compounds were synthesized in one pot. Enaminones E1 and E2 were reacted with substituted benzaldehydes and urea/thiourea in the presence of glacial acet...
Crystals of Fd4 were grown by sitting drop vapour diffusion from a reservoir solution containing 25 % (w/v) of polyethylene glycol 400, 0.05 M cadmium chloride and 0.1 M of sodium acetate/acetic acid buffer, pH 4.6, in a flexible glove box (Coy Laboratories, Grass Lake, MI) at less than 1 ppm of oxygen. 1 μl of protein solution at a concentration of 10 mg·ml was mixed with 1 μl of this reservoi...
The effects of chloride, nitrate, perchlorate and sulfate ions on the rates of the decomposition of hydrogen peroxide and the oxidation of organic compounds by the Fenton's process have been investigated. Experiments were conducted in a batch reactor, in the dark at pH < or = 3.0 and at 25 degrees C. Data obtained from Fe(II)/H2O2 experiments with [Fe(II)]0/[H2O2]0 > or = 2 mol mol(-1), showed ...
vanadium supported on highly ordered nanoporous silica (vox-lus-1) was synthesized and characterized by xrd, nitrogen adsorption‑desorption isotherms and uv-visible spectrophotometer. direct oxidation of benzene to phenol in liquid phase by h2o2 peroxide were examined by using various solvents (methanol, acetone, acetic acid, acetonitryl). the maximum yield (25%) and selectivity (73%) of the ph...
Tomato plants were foliar sprayed with naphthalene acetic acid (0.02%) and calcium chloride (0.5%, 1%) individually as well as in combination to determine its effect on growth, nutrient uptake, incidence of blossom end rot, fruit yield, and enhancement of shelf life. The results showed increased absorption of calcium in tomato plants and fruits, which were treated with NAA in combination with C...
A new and non-infringing efficient one-pot process for the preparation of catechol-O- methyltransferase (COMT) enzyme inhibitors, entacapone 1 under mild condition, initially reaction 3-methoxy-4-hydroxy-5-nitro-benzaldehyde 5 with 2-cyano acetic acid 13 in presence organic base benzyl Trimethyl ammonium hydroxide, i.e. Triton-B which undergo Knoevenagel condensation to get intermediate 22 is t...
depressive disorders are more common among persons with chronic diseases such as inflammatory bowel disease and anti-inflammatory effect of some antidepressants such as amitriptyline has been reported. acetic acid colitis was induced in both reserpinised (depressed) and non-reserpinised (normal) rats. reserpinised groups received reserpine (6 mg/kg, i.p.) one hour prior to colitis induction. th...
