In this paper we report the synthesis of 2-((E)-1-(2-((E)-1-(2-hydroxyphenyethylideneamino) phenylamino) ethyl) phenol.In addition to its synthesis we present AM1 and B3LYP/6-31G* calculations to characterize the physical properties of this molecule. Finally, the antifungal and antibacterial activities of this derivative have been evaluated Introduction Schiff bases are an important class of li...

nine is excreted on giving tryptophan to rats with a simple thiamine deficiency. 3. It is therefore concluded that thiamine is concerned in the conversion of tryptophan into formylkynurenine. 4. Similar experiments combining biotin and pyridoxine deficiencies suggest that biotin is unlikely to be concerned in any stage in the conversion of tryptophan into hydroxykynurenine. 5. Considerable adva...

In this work firstly CoFe2O4 nanoparticles were synthesized via a hydrothermal method. The temperature, surfactant and capping agent effects on the size of CoFe2O4 nanoparticles were investigated. 2-hydroxyacetophenone used as a good capping agent to produce cubic-like nanostructure. When SDBS used as surfactant, particles had spherical morphology. Nanoparticle was studied by scanning electron ...

Pico- and nanosecond time-resolved resonance Raman (TR3) spectroscopy have been utilized to study the dynamics and structure of p-hydroxyacetophenone (HA) and the p-hydroxyphenacyl-caged phototrigger compound p-hydroxyphenacyl diethyl phosphate (HPDP) in acetonitrile solution. Transient intermediates were detected and attributed to the triplet states of HA and HPDP. Nanosecond-TR3 measurements ...

p-Hydroxyacetophenone was coupled to epoxy-activated Sepharose 6B to generate an afflnity chromatographic matrix to purify aldehyde dehydrogenase. Purified beef liver mitochondrial aldehyde dehydrogenase specifically bound to the support and could be eluted with phydroxyacetophenone. A post-ammonium sulfate (3045%) fraction of bovine liver was applied to the affinity gel column and aldehyde deh...
