Background Acute and chronic effects of nitric oxide on oxidative stress and neuronal demyelination have been reported in human and animal models. Objective Oxidative stress is involved in the pathogenesis of demyelinated animals; thus, this study investigated the effects of nitric oxide system and ethidium bromide on oxidative stress in the hippocampal formation. Methods This experimental...
OBJECTIVE To critically evaluate and summarize available information on the safety of potassium bromide in dogs. DESIGN Systematic review. SAMPLE 111 references reporting safety information relevant to potassium bromide published between 1938 and 2011. PROCEDURES PubMed searches without date limitations were conducted with the terms "potassium bromide" and "sodium bromide" in December 200...
In the title compound, C(12)H(24)N(+)·Br(-), both cyclo-hexane rings adopt the usual chair conformation. The cation and anion are linked by N-H⋯Br hydrogen bonds into a linear chain running along the c axis.
benzyltriphenylphosphonium bromide (btpb) has been applied as an efficient catalyst for the preparation of bis(indolyl)methanes (bims) via electrophilic substitution of indoles with aldehydes in the absence of solvent.
The crystal structure of the title compound, C(11)H(18)N(+)·Br(-), has been determined as part of an ongoing study of the influence of the alkyl chain length on amphiphilic activity of quaternary ammonium salts. The title salt forms a three-dimensional network of ionic contacts through weak C-H⋯Br hydrogen bonds, with donor-acceptor distances in the range 3.757 (2)-3.959 (2) Å, in which methyl ...
A series of indole-based aryl(aroyl)hydrazone analogs of antiplatelet indole-3-carboxaldehyde phenylhydrazone were synthesized by the Schiff base formation reaction and their antiplatelet activity was assessed using human platelet rich plasma. The platelet concentrate was obtained using a two-step centrifugation protocol and ADP, arachidonic acid and collagen were used as inducers of platelet a...
We synthesized 3-aroyl-1-arylpyrrole (ARAP) derivatives as potential anticancer agents having different substituents at the pendant 1-phenyl ring. Both the 1-phenyl ring and 3-(3,4,5-trimethoxyphenyl)carbonyl moieties were mandatory to achieve potent inhibition of tubulin polymerization, binding of colchicine to tubulin, and cancer cell growth. ARAP 22 showed strong inhibition of the P-glycopro...
Therapy with bronchodilators forms the pharmacologic foundation of the treatment of patients with COPD. Bronchodilators can significantly lessen dyspnea, increase airflow, improve quality of life, and enhance exercise performance. While bronchodilators decrease airway resistance and lessen dynamic hyperinflation in patients with COPD, they have not been shown to alter the rate of decline in FEV...
Condensation and cyclization of 5-hydroxy- 1,2,4- thiadiazol-2-yl hydrazine 1 with pyruvic acid, phenacyl bromide, propargyl bromide and ally1 bromide afforded compounds 2,5,7 3, 4 ,6 and 8 respectively, Reaction of 1 with epichforohydrine afforded 4-hydroxy-N-[5-hydroxy- 1 ,3,4-thiadiazoly1] pyrazolidine 9
