Based on a series of 1 H -indol-5-ylamines substituted in the pyrrole ring, the corresponding N -(indol-5-yl)trifluoroacetamides and indol-5-ylaminium trifluoroacetates were prepared. An in silico study showed a wide range of their biological activity, including antimicrobial, antiviral, antiprotozoal, anthelmintic, and antifungal effects. The resu...

A kinetic study of the effect of thermoheliox (inhalation of a helium and oxygen mixture, 70 °C) on the functional hemodynamics of the human brain by functional magnetic resonance imaging was carried out. The dynamic responses of the BOLD signal were found to be biphasic. An empirical equation describing the first phase of the hemodynamic response ...

Effects of irradiation with visible light on the process of self-assembly in an aqueous l -cysteine-silver solution (CSS) and hydrogels based on were investigated using a set of physico-chemical methods. It was found that the exposure to light of CSS and hydrogels based on l -cysteine and silver acetate colors them firstly into yellow and subsequen...

Under UV-A light and anaerobic conditions, the photodegradation of kynurenic acid and tryptophan significantly decreases with an increase in the viscosity of the medium without significant changes in the composition of the formed products. The recombination products of tryptophan radicals (covalently linked dimeric forms) exhibit the most pronounce...

The temperature dependence of the degenerate electron exchange (DEE) between the guanosine-5′-monophosphate cation and its short-lived radical dication in an aqueous solution was studied by the chemically induced dynamic nuclear polarization (CIDNP) method with the microsecond time resolution. Based on the simulation of the CIDNP kinetic data, the ...

New compounds with the rosiaite type structure LaM1/3Sb5/3O6, M = Co, Ni, and Cu, were synthesized. The compounds belong to quasi-two-dimensional magnets, in which magnetic interactions occur in the layers with a honeycomb structure. It is shown that there is no long-range magnetic order in these compounds. The temperature and field dependences of ...

Glycyrrhizic acid (GA) is the active ingredient in licorice root, which exhibits a wide range of biological activities, including anti-inflammatory and antiviral activities. In particular, the virus-inhibiting effect of GA on SARS-associated coronavirus was demonstrated. In addition, GA was found to be capable of increasing bioaccessibility of othe...

1,3,5-Tris(2-diphenylphosphoryl-4-ethylphenoxymethyl)benzene (L′), a phosphorylcontaining tripodand, was synthesized for the first time in order to find extraction systems for efficient recovery of lanthanides. The main regularities of extraction of lanthanide(III) ions with mixtures of L′ and 4-benzoyl-5-methyl-2-phenyl-3-pyrazolone (HL) into CHCl...
