The aim of the work was to study antioxidant activity 4-R-3- (morpholinomethyl)-4H-1,2,4-triazole-5-thioles and their alkyl derivatives in vitro using method non-enzymatic initiation lipid peroxidation. Among 45 compounds studied, 8 showed varying degrees AOA. most pronounced AOA has 4-amino-3-(morpholinomethyl)-4H-1,2,4-triazole-5-thiol. It found that cases introduction alkyl-derivatives 4-R-3...

About half of the drugs currently produced are chiral compounds, and about 90 % these compounds sold as racemates, consisting an equimolar mixture two enantiomers. Although they have same chemical structure, most optical isomers substances show marked differences in biological activity. It is known that presence a single asymmetric atom has become almost integral part advanced drug design. The ...

The new ligands, 1-(4-isopropyl phenyl)-4-(2-pyridyl)-1,2,3-triazole, 1 and 1-(mesityl)-4-(2-pyridyl)-1,2,3-triazole, 2 were prepared by the reactions of the respective azides with 2-ethynylpyridine following the "click method". These ligands together with the reported ligands 1-(phenyl)-4-(2-pyridyl)-1,2,3-triazole, 3 and 1-(benzyl)-4-(2-pyridyl)-1,2,3-triazole, 4 were reacted with palladium a...

two novel 3-amino-5-(4-choloro-2-phenoxyphenyl)-4h-1,2,4-triazole derivatives were prepared and their anticonvulsant activity was measured by evaluation of the ability of these compounds to protect mice against convulsion induced by lethal doses of pentylenetetrazole (ptz). diazepam (sigma) was considered as a positive control drug with anticonvulsant effect [ed50 = 1.2 (0.5-1.9) mg/kg]. amongs...

Oligonucleotides containing internal triazole-3'-LNA linkages bind to complementary RNA with similar affinity and specificity to unmodified oligonucleotides, and significantly better than oligonucleotides containing triazole alone. In contrast LNA on the 5'-side of the triazole does not stabilise duplexes. Triazole-LNA confers great resistance towards enzymatic degradation relative to LNA alone.

Thiazolotriazole derivatives have a number of biological activities. Electrophilic intramolecular cyclization unsaturated alkyl 1,2,4-triazole under the action various electrophilic reagents (halogens, tetrahalides chalcogenides) is most effective and simple method synthesis thiazolotriazoles.
 It was previously reported that 3-metalylthio-4,5-diphenyl-1,2,4-triazole reacts with aryltellur...
