a new magnetic nanocatalyst has been prepared using immobilization of vanadate onto aminopropyl functionalized sio2/fe3o4(vo3-/nh3+-sio2/fe3o4). the obtained magnetic catalyst was characterized by ft-ir, xrd, vsm and sem techniques and used for sulfoxidation of sulfide compounds to the correspondingsulfoxides in presence of h2o2 as oxidant at room temperature. the optimum of reaction conditions...

Behavioral stimulants have widespread potential application in the treatment of affective disorders, disorders of vigilance, and disorders of sleep. Most behavioral stimulants, however, must be used with extreme caution because of undesirable side effects that include stereotypy, anxiolytic effects, and addiction. Adrafinil, developed in France by Louis Lafon Laboratories, is a novel pharmaceut...

A simple and rapid normal-phase HPLC method for enantiospecific separation of a psychostimulant, adrafinil (ADL), and its metabolite modafinil (MDL) in rat serum and urine was developed. The separation was accomplished on a normal-phase polysaccharide stationary phase Chiralcel OJ-H using n-hexane-ethanol (62:38 v/v) as a mobile phase at a flow rate of 1.0 mL/min. Detection was carried out at 2...

four conformationally restricted analogues of pentamidine were prepared. then, different concentrations (0.039, 0.078, 0.156, 0.312 and 0.625 mg/ml) of each compound and two positive controls (amphotericin b and pentamidine, 0.625 mg/ml), one negative control (culture medium) and one solvent control (dmso) were prepared and placed in 24-well plates containing 50000 parasite per well. promastigo...

Objective(s) In recent years highly selective COX-2inhibitors were withdrawn from the market because of an increased risk of cardiovascular complications. In this study we were looking for potent compounds with moderate selectivity for cox-2. So, four analogues of 4, 5-diaryl-2-(2-alkylthio-5-imidazolyl) imidazole derivatives were synthesized and their anti-inflammatory and anti-nociceptive ac...

Moclobemide is a selective and reversible monoamine oxidase-A inhibitor, which is used as an antidepressant. Three moclobemide analogues were synthesized by replacing moclobemide phenyl ring with substituted imidazoles. So, N-[(4-morpholinyl) ethyl)]-1-benzyl-2-(alkylthio)-1H-imidazole-5-carboxamides (7a-c) were synthesized and studied for the antidepressant activity using forced swimming test ...

chromanone derivatives demonstrate remarkable cytotoxity against a varieties of cancer cell lines. novel 9-[hydroxy(substitutedphenyl)methyl]-2,2-dimethyl-2,3,8,9- tetrahydro-4h,10h-pyrano[2,3-f]chromene-4,10-diones as glyasperin analogues were synthesized in four steps from known 4-chromone 1. the key step was the preparation of chromane dione 5a by regioselective intramolecular cyclization re...

it is important to determine whether a candidate molecule is capable of penetrating the plasma-brain barrier indrug discovery and development. the aim of this paper is to establish a predictive model for plasma-brainbarrier penetration using simple descriptors the usefulness of the quantum chemical descriptors, calculated atthe level of the dft and he theories using 6-310* basis set for qsar st...
