Аннотация: Effects of new 1,3,4-thiadiazines on human platelet aggregation were studied in vitro. All 1,3,4-thiadiazines inhibited aggregation induced by ADP and arachidonic acid in a wide range of concentrations. The most active of the studied 1,3,4-thiadiazines were L-19, L-20, L-25, L-28, and L-31 in concentrations of 0.01-1 mM, effectively reducing platelet aggregation induced by arachidonic acid and ADP.

Заглавие : Antiviral properties, metabolism, and pharmacokinetics of a novel azolo-1,2,4-triazine-derived inhibitor of influenza A and B virus replication

Аннотация: Influenza viruses of types A and B cause periodic pandemics in the human population. The antiviral drugs approved to combat influenza virus infections are currently limited. We have investigated an effective novel inhibitor of human influenza A and B viruses, triazavirine {2-methylthio-6-nitro-1,2,4- triazolo[5,1-c]-1,2,4-triazine-7(4Í)-one} (TZV). TZV suppressed the replication of influenza virus in cell culture and in chicken chorioallantoic membranes, and it protected mice from death caused by type A and B influenza viruses. TZV was also effective against a rimantadine-resistant influenza virus strain and against avian influenza A virus H5N1 strains. The pharmacokinetic parameters and bioavailability of TZV were calculated after the administration of TZV to rabbits. The TZV metabolite AMTZV {2-methylthio-6-amino-1,2,4- triazolo[5,1-s]-1,2,4-triazin(e)-7(4Í)-one} was discovered inÍÅK 293T and Huh7 cell cultures, a liver homogenate, and rabbit blood after intragastric administration of TZV. AMTZV was nontoxic and inactive as an inhibitor of influenza virus in cell culture. Most likely, this metabolite is a product of TZV elimination

Аннотация: Triterpene derivatives with an α,β-alkenenitrile moiety in the five-membered ring A have been synthesized by nitrile anion cyclizations of 1-cyano-2,3-secotriterpenoids. Oxime-containing precursors, 2,3-secointermediates and five-membered ring A products of cyclizations were screened for in vitro antiviral activity against enveloped viruses – influenza A virus and human immunodeficiency virus type I (HIV-1). Lupane ketoxime and the 2,3-secolupane C-3 aldoxime which possess antiviral activities against both influenza A virus (EC50 12.9–18.2 μM) and HIV-1 (EC50 0.06 μM) were the most promising compounds.

Ключевые слова (''Своб.индексиров.''): alfa,beta- alkenenitriles--a-seco-triterpenoids--allobetulone
Аннотация: A-seco-triterpenoids with a methylketone group were synthesized from epimeric 3-hydroxy-3-methyl-1-cyano-2,3-seco-triterpenoids of the lupane and 19β,28-epoxy-18αH-oleanane types, which were formed by a Grignard reaction. The resulting methylketones underwent under base-catalysis conditions an intramolecular cyclization to form A-pentacyclic β-substituted alkenenitriles. The synthesized compounds included 3-methyl-1-cyano-19β,28- epoxy-2,3-seco-2-nor-18αH-olean-3-one and methyl 3-methyl-1-cyano-2- norlup-1(3),20(29)-dien-28-oate, which inhibited in vitro reproduction of human immunodeficiency virus type 1.

Ключевые слова (''Своб.индексиров.''): 2-arylhydrazinylidene-3-oxo-3-polyfluoroalkylpropionates--inhibitors--carboxylesterase
Аннотация: A series of alkyl 2-Arylhydrazinylidene-3-oxo-3-polyfluoroalkylpropionates was synthesized and their inhibitory activity with respect to porcine liver carboxylesterase (CaE, EC 3.1.1.1), human erythrocyte acetylcholinesterase (AChE, EC 3.1.1.7), and horse serum butyrylcholinesterase (BChE, EC 3.1.1.8) was studied. The molecular docking method was used to study the binding mode of the compounds in the active site of CaE. It was found that compounds containing the trifluoromethyl group in the third position of carbonyl chain are highly effective and selective inhibitors of CaE with nanomolar IC50 values, which agrees well with the results of molecular docking.

Аннотация: Particular success has been achieved in the synthesis of new products and in processes since the twelve principles of "green chemistry" were formulated in the 1990s. These products and processes are more compatible with human health, society, and the environment. In this review, a collection of research reports have been documented from the viewpoint of green chemistry. The main theme of this review is neat reactions, which are solvent and catalyst-free reactions. Neat reactions in the absence of any solvent or catalyst with concise summaries of microwave, ball milling, and neat reactions have been described.

Заглавие : Dataset of NMR-spectra pyrrolyl- and indolylazines and evidence of their ability to induce heat shock genes expression in human neurons
Место публикации : Data in Brief. - 2021. - № 39. - С. 107562
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Ключевые слова (''Своб.индексиров.''): pyrrolylazines--indolylazines--photocatalysis--nuclear magnetic resonance--green chemistry
Аннотация: These data are related to our previous paper “Synthesis and approbation of new neuroprotective chemicals of pyrrolyl-and indolylazine classes in a cell model of Alzheimer’s disease” (Dutysheva et al., 2021), in which we demonstrate neu-roprotective abilities of pyrrolyl- and indolylazines in a cell model of Alzheimer’s disease. Using a novel procedure of photocatalysis we have synthesized a group of new compounds. The current article presents nuclear magnetic resonance spectra including heteronuclear single quantum coherence spectra of chemicals synthesized by us. The effect of new compounds have on heat shock proteins genes expression in reprogrammed human neurons are presented. We also presented data that verify neuronal phenotype of reprogrammed cells.

Заглавие : Stimuli-responsive dual cross-linked N-carboxyethylchitosan hydrogels with tunable dissolution rate
Место публикации : Gels. - 2021. - Vol. 7, № 4. - Ст.188
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Ключевые слова (''Своб.индексиров.''): hydrogels--chitosan--salicylaldehyde
Аннотация: Here, we discuss the applicability of (methylenebis(salicylaldehyde)—MbSA) for the fabrication of the stimuli-responsive N-carboxyethylchitosan (CEC) hydrogels with a tunable dissolution rate under physiological conditions. In comparison with non-covalent salicylimine hydrogels, MbSA cross-linking via covalent bis(‘imine clip’) and non-covalent hydrophobic interactions allowed the fabrication of hydrogels with storage moduli 1 kPa at ten-fold lower aldehyde/CEC molar ratio with the preservation of pH- and amino-acid responsive behavior. Although MbSA-cross-linked CEC hydrogels were stable at neutral and weakly alkaline pH, their disassembly in cell growth medium (Dulbecco’s modified Eagle’s medium, DMEM) under physiological conditions was feasible due to transimination reaction with amino acids contained in DMEM. Depending on the cross-linking density, the complete dissolution time of the fabricated hydrogels varied from 28 h to 11 days. The cytotoxicity of MbSA cross-linked CEC hydrogels toward a human colon carcinoma cell line (HCT 116) and primary human dermal fibroblasts (HDF) was remarkably lower in comparison with CEC-salicylimine hydrogels. Fast gelation, relatively low cytotoxicity, and tunable stimuli-induced disassembly under physiological conditions make MbSA cross-linked CEC hydrogels promising for drug encapsulation and release, 3D printing, cell culturing, and other biomedical applications.
