Cyclic oligonucleotides and analogues (cONs) are highly specific ligands for DNA, RNA and proteins. cONs are described in several diagnostic and therapeutic applications, as well as in elucidating enzyme mechanisms and as lead structures for development of new drugs because of their unusual chemical and biological properties in comparison with linear counterparts. In numerous structural studies it has been shown tha Read More

Non-steroidal anti-inflammatory drugs (NSAIDs) are an important class of therapeutics, incorporate a heterocyclic core in their molecular structure and are used for the alleviation of pain and inflammation associated with several pathological conditions. NSAIDs exert anti-inflammatory effects by inhibiting cyclooxygenase enzymes (COXs) which, are useful in the synthesis of prostanoids generated from arachidonic acid. Selective C Read More

This article discusses advantages and limitations of the biotransformations with enzymes and whole-cell catalysts. It reviews biocatalytic synthesis of the chiral, organophosphorus compounds of different structures and characterizes their biological importance.

Recent investigations on silole derivatives have shown that materials based on siloles possess a number of intriguing properties, such as high charge carrier mobilities, high photoluminescence quantum yields, and good thermal stabilities, which are favorable for the applications in organic optoelectronic devices. Great achievements have been made in the silole-based conjugated materials for high performance optoelectro Read More

The reaction of 5-aminouracil with peroxyl radicals generated by the thermal decomposition of 2,2'-azo-bis(2- methylpropionitrile) (AIBN) and 2,2'-azo-bis(2-amidinopropane) dihydrochloride was studied at 50°C in ethanol and water (pH 7.0) solution respectively. The oxidation product of 5-aminouracil formed by peroxyl radicals was dihydro-5,5,6-trihydroxypyrimidine-2,4-dione. The relative rate constant of 5-aminouracil vs. Read More

The electrophilic amination of functionalized organocopper and organozinc reagents by N,N-dialkyl-O-benzoyl hydroxylamine derivatives to provide functionalized tertiary aryl amines has been accomplished efficiently at ambient temperature using in situ generated Fe(0) nanoparticles from Fe(acac)3. The formation and role of Fe(0)-nanoparticles were investigated. The mechanism involving Feassisted nucleophilic displacem Read More
