Abstract

The combination of various heterocyclic systems with a wide range of properties is quite expedient and is, in practice, a justified direction for obtaining biologically active substances, which ultimately forms a favorable basis for the creation of drugs. In recent decades, the attention of scientists has been closely focused on nitrogen-containing heterocyclic compounds. Among such compounds, 1,2,4-triazole and pyrazole occupy a special place. Indeed, on the basis of these systems, a significant number of well-known drugs have been created, which are widely used at the present time.

The aim of the work was the synthesis of S-derivatives of 4-amino-5-(5-methylpyrazol-3-yl)-1,2,4-triazole-3-thiol, study of their physical and chemical properties, pre-screening studies with subsequent establishment of the feasibility of further pharmacological studies.

Materials and methods. Experimental methods of organic chemistry: synthesis using microwave activation, physical and chemical methods for the analysis of organic compounds (determination of the melting point, elemental analysis, 1H NMR, IR spectroscopy and chromatography-mass spectrometry). Methods for in silico pre-screening studies to establish the biological potential in several synthesized compounds (molecular docking).

Results. 10 new S-derivatives of 4-amino-5-(5-methylpyrazol-3-yl)-1,2,4-triazole-3-thiol were synthesized. The structure of the obtained compounds was confirmed by a set of physical and chemical methods of analysis. According to the results of prescreening studies, the main directions of research of biological properties of synthesized compounds were provided.

Conclusions. The expediency of using microwave irradiation in the synthesis of a series of S-alkyl derivatives of 4-amino-5-(5-methylpyrazol-3-yl)-1,2,4-triazole-3-thiol had been proved. Based on the results of in silico studies, the expediency of further studies of anti-inflammatory, antifungal and anticancer activities in several synthesized compounds had been substantiated.
