Abstract

Topicality. There is a tendency to increase the number of generics in comparison with the original drugs at the present national pharmaceutical market. A few new drugs registered which contain new substances. Thus, the already wellknown drugs appear under new names, while their pharmacological effect is not stronger and safer.
The aim of this work was to synthesize and to study structure confirmation of novel 5,5’-(R-diylbis(sulfanediyl)) bis(3-(thiophen-2-ylmethyl)-4H-1,2,4-triazole-4-amines).
Materials and methods. There are synthesized new 5,5’-(R diylbis(sulfanediyl))bis(3-(thiophen-2-ylmethyl)-4H- 1,2,4-triazole-4-amines). Structure of substances was established by the modern physical and chemical methods of analysis (Elemental analysis, 1H-NMR-spectroscopy, HPLC-MS).
Results and discussion. There are synthesized 5,5’-(R-diylbis(sulfanediyl))bis(3-(thiophen-2-ylmethyl)-4H-1,2,4-triazole-4-amines) and 5,5’-(R-1,3-diylbis(sulfandiyl))bis (N-R-iden-3-(thiophen-2-ylmethyl)-4H-1,2,4-triazole-4-amines.
Conclusions. The structure of synthesized substances was established by the modern physical and chemical methods of analysis (Elemental analysis, 1H-NMR-spectroscopy, HPLC-MS)
