Several 6-aryl-4-substituted benzylidene/furfurylidene pyridazin(2H)-3-one derivatives (4a-f) were synthesized and evaluated as analgesic and anti-inflammatory agents in mice and rats, respectively. All compounds were tested by using Eddy’s hot plate and the carrageenan-induced hind paw oedema method for the evaluation of analgesic and anti-inflammatory activities, respectively. Results showed ...
The synthesis of new N-(3-substituted-benzylidene-2-oxoindolin-5-yl) acetamide (5-14) derivatives along with their inhibitory activity against Src is reported. Among all compounds, only 10, 12 and 13 were found slightly active against Src with IC50 values of 3.55, 6.39 and 7.29 mM, respectively. Docking studies have been also performed to analyze the binding mode of compounds and the results sh...
A series of quinoidal thiophene based dye molecules were designed and their optoelectronic properties were studied for dye sensitized solar cell (DSSC) applications. The efficiency of the designed dye molecules was analyzed using various parameters such as the HOMO-LUMO energy gap, absorption spectra, light harvesting efficiency (LHE), exciton biding energy (Eb) and free energy change for elect...
Polar, noncentrosymmetric packing of directional, 1-D hydrogen-bonded networks of chiral, 4-amino-2,6-bis(oxazolinyl)pyridines (ampybox) occurs for isopropyl-substituted ampybox; in contrast, 1-D networks of methyl-substituted ampybox pack in an antiparallel arrangement.
The methoxy-substituted bis-1,2,3-dithiazolyl radical 4a thermally decomposes to afford the zwitterionic bis-1,2,3-dithiazolopyridone 5a; EPR spectroscopic analysis indicates a rearrangement of the radical prior to loss of the methyl group.
3-methyl-1-(4-sulfobuthyl)-1-h-imidazol-3ium hydrogen sulfate, as a dual acidic ionic liquid (dail), was found to be an efficient catalyst for the simple, rapid and green synthesis of substituted trisphenols from the condensation of different substituted phenols and 2,6-bis (methylol) phenols (bmp). dail catalyst efficiently promoted the reaction between phenols and bmps with a variety of funct...
α-Tropomyosin (Tm) carrying hypertrophic cardiomyopathy mutation D175N or E180G was expressed in Escherichia coli. We have assembled dimers of two polypeptide chains in vitro that carry one (αα*) or two (α*α*) copies of the mutation. We found that the presence of the mutation has little effect on dimer assembly, thereby predicting that individuals heterozygous for the Tm mutations are likely to...
BACKGROUND Recent studies have discovered that α-globin is expressed in blood vessel walls where it plays a role in regulating vascular tone. We tested the hypothesis that blood pressure (BP) might differ between normal individuals and those with α+thalassemia, in whom the production of α-globin is reduced. METHODS AND RESULTS The study was conducted in Nairobi, Kenya, among 938 adolescents a...
Eight different zirconium phenoxyimine complexes were synthesized, characterized and tested as catalysts for ethylene polymerization. The phenoxyimine compounds were prepared by condensation of substituted salicylaldehydes with aliphatic and aromatic amines, the substituted salicylaldehydes from ortho substituted phenols and paraformaldehyde. The introduction of iodo substituents was achieved e...
