A reaction from various kinds of nitroquinoline with hydroxylamine in potassium hydroxide alkalinity produced a novel product, furazanoquinoline, besides the known amino derivatives. The products obtained were furazano [3,4-f] quinoline (5) from 5-nitroquinoline (1) and 6-nitroquinoline (6), and furazano [3,4-h] quinoline (10) from 7-nitroquinoline (8) and 8-nitroquinoline (11). The reaction me...

From the time immemorial, sodium borohydride has been used for the reagent of choice for reducing various carbonyl compounds and acid chlorides in protic solvents. Over the past decades the utility of sodium borohydride has been greatly expanded and various modifications have been developed. Reductive dechlorination of aromatic halo nitro compounds have a great significance in the field of orga...

Aims: To examine the properties of hydrazide compounds shown to inhibit Mycobacterium tuberculosis. To identify properties that affect efficiency of bacterial inhibition. Study Design: Utilizing data from previous studies of compounds that inhibit Mycobacterium tuberculosis, then statistical and pattern recognition methods are applied to identify interrelationships. Place and Duration of Study:...

Simple synthesis of modafinil derivatives and their biological activity are described. The key synthetic strategies involve substitution and coupling reactions. We determined the anti-inflammatory effects of modafinil derivatives in cultured BV2 cells by measuring the inhibition of nitrite production and expression of iNOS and COX-2 after LPS stimulation. It was found that for sulfide analogues...

Pro-aromatic molecules have higher-energy diradicaloid states that are significantly influenced by resonance structures in which conjugated rings take on Hückel-aromatic character. Recently, it has been argued there also pro-aromatic adopt central units with 4nπ-electron Baird-aromatic character the T1 state, although detailed analysis suggests these compounds better labelled as Hückel–Baird hy...

Aromatic compounds are widely distributed in nature. They are found as lignin components, aromatic amino acids, and xenobiotic compounds, among others. Microorganisms, mostly bacteria, degrade an impressive variety of such chemical structures. Various aerobic aromatic catabolic pathways have been reported in bacteria, which typically consist of activation of the aromatic ring through oxygenases...

A self-developed and newly re-designed chemical SAW sensor system composed of four polymer-coated differently modified nano-diamond-coated sensors was applied to measure aromatic compounds in gasoline a low-cost, fast, easy way. An additional short packed column at the inlet improve selectivity for various possible fuel applications. The allows direct sampling liquid fuels pre-separates differe...

We designed and studied hydrocarbon model compounds by high-resolution noncontact atomic force microscopy. In addition to planar polycyclic aromatic moieties, these novel model compounds feature linear alkyl and cycloaliphatic motifs that exist in most hydrocarbon resources - particularly in petroleum asphaltenes and other petroleum fractions - or in lipids in biological samples. We demonstrate...

The aromatic polyketones 3a-d are versatile compounds for the synthesis of the multi-1,2,3-selenadiazole aromatic derivatives 1a-d. The preparation starts with the reaction between the multi-bromomethylene benzene derivatives 2a-d and 4-hydroxy- acetophenone to give compounds 3a-d which are transformed through the reaction with semicarbazide hydrochloride or ethyl hydrazine carboxylate into the...
