We considered it timely to test the applicability of transferable multipole pseudo-atoms for restoring inner-crystal electronic force density fields. The procedure was carried out on crystal 1,3-bis(2-hydroxyethyl)-6-methyluracil, and some derived properties scalar potential vector fields were compared with those obtained from experimental model aspherical pseudo-atom parameters fitted calculated structure factors. shown accurately replicate general vector-field behavior, peculiarities...
Abstract Novel 6‐methyluracil derivatives with ω‐(substituted benzylethylamino)alkyl chains at the nitrogen atoms of pyrimidine ring were designed and synthesized. The numbers methylene groups in alkyl varied along electron‐withdrawing substituents on benzyl rings. compounds are mixed‐type reversible inhibitors cholinesterases, some them show remarkable selectivity for human acetylcholinesterase (hAChE), inhibitory potency nanomolar range, more than 10 000‐fold higher that...
A series of bisuracils, in which uracil and 3,6-dimethyluracil moieties were bridged with a polymethylene spacer, the moiety contained pentamethylene radical ionic non-ionic aminobenzyl groups, synthesised. These bisuracils have been identified as cholinesterase inhibitors exceptional selectivity for acetylcholinesterase (AChE) over butyrylcholinesterase (BuChE). highly effective AChE inhibitors, demonstrated activity at nano- sub-nanomolar concentrations, BuChE. In kinetic studies lead 2b...
A series of 5'-phosphorylated (dialkyl phosphates, diaryl phosphoramidates, H-phosphonates, phosphates) 1,2,3-triazolyl nucleoside analogues in which the 1,2,3-triazole-4-yl-β-D-ribofuranose fragment is attached via a methylene group or butylene chain to N-1 atom heterocycle moiety (uracil quinazoline-2,4-dione) was synthesized. All compounds were evaluated for antiviral activity against influenza virus A/PR/8/34/(H1N1). Antiviral assays revealed three compounds, 13b, 14b, and 17a, showed...
In this study, novel derivatives based on 6-methyluracil and condensed uracil were synthesized, namely, 2,4-quinazoline-2,4-dione with ω-(ortho-nitrilebenzylethylamino) alkyl chains at the N atoms of pyrimidine ring. series synthesized compounds, polymethylene varied from having tetra- to hexamethylene chains, secondary NH, tertiary ethylamino, quaternary ammonium groups introduced into chains. The molecular modeling compounds indicated that they could function as dual binding site...
The series of novel pyrimidine-containing amphiphiles were examined as catalysts for cleavage phosphonates having various hydrophobicities. Kinetic data showed marked substrate specificity three different types (i) inhibition both substrates, (ii) catalysis more hydrophobic phosphonate and less phosphonate, (iii) substrates. highest acceleration (more than 11 times in comparison with the reaction absence amphiphile) has been reached case dicationic amphiphile tails.
The crystal and electronic structure of an isocyanuric acid derivative was studied by high-resolution single-crystal X-ray diffraction within the Hansen–Coppens multipole formalism. observed deformation electron density shows signs thermal smearing. experimental picture meaningfully assigned to consequences unmodelled anharmonic atomic motion. Straightforward simultaneous refinement all parameters, including Gram–Charlier coefficients, resulted in more significant distortion apparent static...
A series of 1,2,3-triazolyl nucleoside analogues in which 1,2,3-triazol-4-yl-β-d-ribofuranosyl fragments are attached via polymethylene linkers to both nitrogen atoms the heterocycle moiety (uracil, 6-methyluracil, thymine, quinazoline-2,4-dione, alloxazine) or C-5 and N-3 6-methyluracil was synthesized. All compounds synthesized were evaluated for antiviral activity against influenza virus A/PR/8/34/(H1N1) coxsackievirus B3. Antiviral assays revealed three compounds, 2i, 5i, 11c, showed...
Alzheimer's disease (AD) is the major age-related progressive neurodegenerative disorder. The brain of AD patients suffers from loss cholinergic neurons and decreased number synapses [1]. caused by an imbalance between Aβ production clearance, resulting in increased amount various forms [2]. Reduction increasing clearance pathogenic are key targets development potential therapeutic agents for treatment. Unfortunately, only nosotropic approaches treatment currently effective humans. These...
A series of 1,2,3-triazolyl nucleoside analogues bearing N-acetyl-D-glucosamine residue was synthesized by the copper-catalyzed alkyne-azide cycloaddition (CuAAC) reaction N1-ω-alkynyl derivatives uracil, 6-methyluracil, thymine and 3,4,6-tri-O-acetyl-2-deoxy-2-acetamido-β-D-glucopyranosyl azide. Antiviral assays revealed lead compound 3f which showed both same activity against influenza virus H1N1 (IC50=70.7 µM) as antiviral drug Rimantadine in control (IC50=77 good Coxsackievirus B3...
С применением комплекса физико-химических методов (тензиометрия, кондуктометрия, динамическое и электрофоретическое рассеяние света, флуориметрия, спектрофотометрия) изучена агрегирующая способность функциональная активность (солюбилизирующая способность, комплексообразование с декамером ДНК) дикатионного амфифильного пиримидинофана.Установлено, что протяженность степень насыщенности гидрофобного радикала в урациловом фрагменте не оказывает влияния на величину критической концентрации...
