New S-substituted 4-alkyl-5-((3-(pyridin-4-yl)-1H-1,2,4-triazole-5-yl)thio)methyl)-4H-1,2,4-triazole-3-thiol derivatives have been designed, synthesized and studied their antimicrobial activity on 11 standard Gram-positive and Gram-negative microorganism strains. Their spectral and physicochemical parameters were established using modern comprehensive methods of analysis, including 1H NMR spectroscopy, GC-MS and elemental analysis.It has been found that compound 2a exhibits strong suppression of 5 test strains (MBC = 15.6 µg/mL). Compound 4a showed moderate inhibition of Salmonella

About half of the drugs currently produced are chiral compounds, and about 90 % of these compounds are sold as racemates, consisting of an equimolar mixture of two enantiomers. Although they have the same chemical structure, most of the optical isomers of chiral substances show marked differences in biological activity. It is known that the presence of a single asymmetric atom has become almost an integral part of advanced drug design. The aim of this work was to determine the angle of rotation of the polarization plane of solutions of some S-derivatives of 4-R-5-((((3-(pyridin-4-yl)-1H-1,2,4-

In this work, we present the spectral analysis of 1 H- and 2 H-1,2,3-triazole vibrationally excited states alongside provisional and practical computational predictions of the excited-state quartic centrifugal distortion constants. The low-energy fundamental vibrational states of 1 H-1,2,3-triazole and five of its deuteriated isotopologues ([1-2H]-, [4-2H]-, [5-2H]-, [4,5-2H]-, and [1,4,5-2H]-1 H-1,2,3-triazole), as well as those of 2 H-1,2,3-triazole and five of its deuteriated isotopologues ([2-2H]-, [4-2H]-, [2,4-2H]-, [4,5-2H]-, and [2,4,5-2H]-2 H-1,2,3-triazole), are studied using millime

In pursuit of obtaining steroid derivatives containing a triazole moiety in their structure, a series of reactions was conducted (Figure 1). In these reactions, an intermediate compound was the corresponding azide 3, which was subsequently involved in a reaction with the required alkyne to form a 1,2,3-triazole. In click chemistry reactions, it is well-known that catalysts are one-valent copper salts, which can be generated in situ from copper(II) salts. However, the NMR spectra of the main product, isolated from the reaction mass, did not match the expected results.Figure 1. The procedure for
