Заглавие : Peptide ligands on the PEGylated nanoparticle surface and human serum composition are key factors for the interaction between immune cells and nanoparticles
Место публикации : Colloids and Surfaces B: Biointerfaces. - 2023. - Vol. 221. - С. 112981
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: The architecture of a nanoparticles' surface formed due to a modification with a ligand and protein corona formation in biofluids is critical for interactions with cells in vivo. Here we studied interactions of immune cells with magnetic nanoparticles (MNPs) covalently modified with polyethylene glycol (PEG) and their counterparts conjugated with peptides: a pH (low) insertion peptide (pHLIP) and cycloRGD as a targeting ligand in human serum. The conjugation of MNPs-PEG with pHLIP, but not with cycloRGD, enhanced the association of these particles with mononuclear phagocytic cells in vitro and in vivo. We did not find a clear difference in protein corona composition between the pHLIP-modified and parental PEGylated nanoparticles. Analysis of the effect of autologous human serum on MNP uptake by monocytes showed that the efficiency of endocytosis varies among healthy donors and depends on intrinsic properties of serum. Nevertheless, using classic blood, coagulation, biochemical tests, and anti-PEG IgG serum level, we failed to identify the cause of the observed interdonor variation. These individual differences should be taken into consideration during testing of nanotherapeutics.

Заглавие : Expanding 1,2,4-triketone toolbox for use as fluorinated building blocks in the synthesis of pyrazoles, pyridazinones and β-diketohydrazones
Место публикации : Journal of fluorine chemistry. - 2022. - Vol. 253. - Ст.109932
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Fluorinated lithium β-diketonates bearing a methyl acetal group behave in the condensation reactions with hydrazines as trielectrophilic building blocks for the preparation of pyrazoles, pyridazinones and β-diketohydrazones. For the first time, solvent-induced regioisomeric and heterocyclic ring size-controlled formation was observed for 1,2,4-triketone analogues. Fluoroalkylated acetyl NH-pyrazoles or substituted 5-RF-pyrazoles were obtained from the acid-catalyzed cyclocondensation of lithium β-diketonates with (aryl)hydrazines in ethanol. In methanol solvent acetyl-containing 3-CF3-pyrazoles were isolated because of inverse nucleophilic attack of arylhydrazines. The use of aprotic acetonitrile in the condensation resulted in regioselective trifluorinated pyridazinones and fluorinated β-diketohydrazones formation via initial acetal fragment interaction with N,N-dinucleophile.

Ключевые слова (''Своб.индексиров.''): isomerization--spectroscopy--elemental analysis
Аннотация: 1-Phenyl-4,5-dihydroxy-4,5-bis(trifluoromethyl)imidazolidin-2-one was synthesized by the reaction of perfluorobiacetyl with phenylurea. Reaction of the former with urea was studied in comparison with the similar interaction of N-methyl-substituted and unsubstituted analogues. N-phenylimidazolidine was shown to yield trifluoromethylated imidazooxazol and hydantoin when heated with urea in dimethylacetamide, in contrast to unsubstituted analog which gives trifluoromethylated glycoluril under the same conditions. The similar reaction in dioxane led to isomerization of cis-isomers of the starting imidazolidines to corresponding trans-isomers. Structure of the reaction products was proved by IR, 1H, 13C and 19F spectroscopy, HR mass spectrometry, elemental analysis and XRD analysis.

Заглавие : Influence of the structure of the aminoalkyl group in polysiloxane on the selectivity of its interaction with metal ions
Место публикации : Russian Journal of Applied Chemistry. - 2021. - Vol. 94, № 4. - С. 478-485
ББК : Г
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Polysiloxanes containing nonchelating 3-aminopropyl and chelating N-(2-aminoethyl)-3-aminopropyl groups with the degree of functionalization of 28 and 24%, respectively, were prepared by sol–gel synthesis. The polysiloxanes obtained showed comparable activity in sorption of Pd(II), Pt(IV), Fe(III), Cd(II), Zn(II), Co(II), Ni(II), Cu(II), Mn(II), Pb(II), Ca(II), and Mg(II) ions from model multicomponent solutions. At pH 3,3-aminopropylpolysiloxane selectively takes up platinoid ions. The chelating structure of N-(2-aminoethyl)-3-aminopropyl groups leads to a decrease in the selectivity of the interaction with Pd(II) ions but increases the affinity for Fe(III), Ni(II), and Cu(II). Preconcentration in the dynamic mode allows quantitative sorption of Pd(II) and Pt(IV), followed by virtually quantitative elution of the metal ions from the sorbent surface.

Ключевые слова (''Своб.индексиров.''): ftir--magnetic nanoparticles--mechanism of immobilization--pmida--tga--xps
Аннотация: The mechanism of N-phosphonomethyl iminodiacetic acid (PMIDA) binding with the Fe3O4 magnetic nanoparticle (MNPs) surface by Fourier transformed infrared spectroscopy, X-ray photoelectron spectroscopy and thermogravimetry was comprehensive studied. To study of microstructure, size and core structure of synthesized nanoparticles the scanning electron microscopy, X-ray diffraction analysis and Raman spectroscopy were carried out. A new scheme for the tridentate bonding of the phosphonomethyl derivative with surface Fe atoms involving unequal P–O–Fe bonds was proposed. The mechanism of thermal decomposition of PMIDA molecules on the MNP surface was studied using a thermogravimetric analyzer combined with infrared spectrometer. It was shown for the first time that during the thermal treatment of phosphonomethyl-modified MNPs, PMIDA molecules are not desorbed from the surface of MNPs but gradually decompose. We believe that obtained in this work data will be useful for a deeper understanding of the mechanisms of phosphonic acid derivatives interaction with MNPs, as well as in the design of new biomedical materials, in which the conjugation of biomolecules with carboxyl groups of PMIDA-modified MNPs is assumed.

Заглавие : Extended cavity pyrene-based iptycenes for the turn-off fluorescence detection of RDX and common nitroaromatic explosives

Ключевые слова (''Своб.индексиров.''): pyrene (chemical)--fluorescence--rdx (cyclonite)
Аннотация: Extended cavity pyrene-based iptycenes have been synthesized by using the Diels–Alder reaction between in situ generated dehydropyrenes and anthracene. The photophysical properties and the interaction of these iptycenes with nitro-explosive components were studied both in solution and in the solid state by using fluorescence spectroscopy and X-ray crystallography, respectively. Due to the presence of both the large iptycene cavity and the central pyrene core, an unprecedently high fluorescence-quenching response towards non-aromatic and non-planar 1,3,5-trinitroperhydro-1,3,5-triazine (RDX) has been observed both in solution (with an apparent Stern–Volmer constant value aKSV up to 1.53 × 103 M−1) and in the vapor phase (50–75% fluorescence quenching of the PU films doped with chemosensors). In the case of nitroaromatic explosives, nitrobenzene (NB), 2,4-DNT, TNT, and 2,4,6-trinitrophenol (TNP or picric acid, PA), pyrene-based iptycenes also demonstrate a good fluorescence-quenching response both in solutions (with apparent Stern–Volmer constant values aKSV = 0.4–8.0 × 103 M−1) and in the vapor phase (up to 90% fluorescence quenching of the PU films doped with chemosensors). The “sphere of action” fluorescence quenching model was suggested.

Ключевые слова (''Своб.индексиров.''): acetoacetamide-containing podands --dihydropyrimidine-containing podands--acetylketene
Аннотация: Reactions of aliphatic aminopodands having different length of the polyether chain with acetoacetic ester and 2,2,6-trimethyl-4H-1,3-dioxin-4-one were studied. The interaction of aminopodands with acetoacetic ester in toluene upon sonication (60A degrees D) or heating (90A degrees D) gave podands with terminal aminocrotonate fragments. The use of dioxinone at the same temperature allowed to transform aminopodands into aliphatic acetoacetamide-containing podands. An asymmetric podand with 2-pyridone fragment was isolated as byproduct from the reaction of dioxinone with 1,5-diamino-3-oxapentane. A three-component Biginelli reaction of acetoacetamidecontaining podands with benzaldehyde and urea in the presence of catalytic amounts of polyphosphoric acid immobilized on nanosized TiO2-SiO2 oxide surface enabled the synthesis of podands with 1,4-dihydropyrimidin-2-(1De)-one fragments.

Ключевые слова (''Своб.индексиров.''): acyclovir
Аннотация: New analogues of acyclovir have been prepared by reacting 1,2,4 -triazolo[1,5-a]pyrimidin-7-ones 1а-i and (2-acetoxyethoxy)methyl acetate 2 in the presence of trimethylsilyl trifluoromethanesulfonate as a catalyst. The interaction between the compounds 1а-е and 2 has led to a mixture of N3 and N4 isomers. In contrast, the reaction of compounds 1g-i and 2 proceeded selectively to form N3 isomers. In the case of compounds 1a-c the predominant product is the one with the acyclic moiety in azine ring (N4 isomer). Interaction between 1d-f and 2 has led to mixtures comprising mainly N3 isomer. It has been found that the ratio of glycosylation products 1 and 2 are thermodynamically controlled. The structure of the obtained compounds has been proved by 1Н, 13С, two-dimensional 1Н-13С NMR spectroscopy and X-ray analysis.

Аннотация: New synthetic routes to trifluoromethylated N-heterocycles based on condensations of 2-methoxy-2-methyl-5-(trifluoromethyl)furan-3(2H)-one with bifunctional N-nucleophiles are described. For the first time, trifluoromethyl-containing pyrazoles, pyrazolines and isoxazolines bearing hydrazone or oxime groups could be obtained by a one-pot strategy based on reactions of 5-(trifluoromethyl)furan-3(2H)-one with two equivalents of the corresponding hydrazines or hydroxylamine in the presence of an acid. The interaction of furan-3(2H)-one with ureas proceeded under mild conditions to furnish 1H-furo[2,3-d]imidazol-2(3H)-one derivatives in good yield. Further, a trifluoromethyl-containing quinoxaline derivative was obtained by condensation of furan-3(2H)-one with ortho-phenylenediamine.

Ключевые слова (''Своб.индексиров.''): sodium aminoprusside --polymer ligands (chitosan)--polyallylamine
Аннотация: Here we report on synthesis of new organic–inorganic materials based on products of interaction between sodium aminoprusside and polymer ligands (chitosan (CS), N-2-(2-pyridyl)ethylchitosan (2-PC), N-2-(4-pyridyl)ethylchitosan (4-PC), N-(4-methyl-5-imidazolyl)methylchitosan (IC), N-(2-cyanoethyl)chitosan (CC), polyallylamine (PA), N-(2-pyridyl)methyl-polyallylamine (PMPA), N-2-(2-pyridyl)ethyl-polyallylamine (PEPA), N-(4-methyl-5-imidazolyl)methyl-polyallylamine (IPA) and poly(2-vinylpyridine) (PVP)). The composition of the obtained materials was characterized using the element analysis and X-ray diffraction; the Fourier transform infrared (FT-IR) spectroscopy and thermogravimetric analysis data were used to propose the structure of the formed complexes. It was established that ion and ligand exchange were the main reactions, through which sodium aminoprusside interacts with water-soluble polymer salts. Reactivity in complex formation reaction of unmodified polymers changes in a row: PA CS PVP. Modification of chitosan with 2-(4-pyridyl)ethyl and 2-cyanoethyl moieties enhances reactivity of chitosan to the level of PA, while introduction of 2-(2-pyridyl) and (4-methyl-5-imidazolyl)methyl moieties, on the contrary, decreases reactivity of chitosan to that of PVP. At the same time, functionalization of PA with 2-pyridylalkyl groups decreases its reactivity in reaction with aminoprusside ion. Thus, reactivity of all studied polymeric matrices changes in the row: PA ≈ 4-PC ≈ CC CS 2-PC ≈ IPA ≈ IC PMPA PVP PEPA. The distribution coefficients with respect to cesium ions have been determined for the synthesized complexes in cobalt(II) form. It has been shown that the complex of chitosan with pentacyanoferrate(II) has higher distribution coefficient with respect to Cs+ ions, as compared to its N-derivatives and synthetic polymers. Organic–inorganic materials obtained in the matrix of synthetic polymers have shown higher tendency to peptization and, therefore, lower sorption capacities and distribution coefficients

Ключевые слова (''Своб.индексиров.''): bacterial degradation--chemical modification--polyethylene glycols
Аннотация: Polychlorinated biphenyls (PCBs), also known by the trade name Sovol, are toxic industrial wastes. They have been subjected to chemical treatment by polyethylene glycols (PEGs) and potassium hydroxide. As a result of the interaction of the Sovol with various molecular mass PEGs (MMPEG-4 ∼ 200, MMPEG-22 ∼ 1000), water-soluble mixtures M1 and M2 containing mono(polyethylene glycol)oxy-derivatives (PCB-PEG-4 and PCB-PEG-22), polychlorobiphenylols, and unreacted PCB congeners (PCB 44, PCB 47, PCB 49, PCB 52, and PCB 66) were obtained. It was shown for the first time that mixtures M1 and M2 are susceptible to bacterial degradation without their fractionation. According to the gas-liquid chromatography with flame-ionization and mass-spectrometric detection, the Rhodococcus wratislaviensis KT112-7 strain degraded all of the chemical compounds occurring in the mixtures. In a 5-day experiment, it was found that the KT112-7 strain decomposes mono(polyethylene glycol)oxy-derivatives completely (by 100%) and polychlorobiphenylols and PCB congeners by 90–95% in the M1 and M2 mixtures. The culture medium did not contain transformation products, whereas free chlorine ions were accumulated (72–94% of the maximum possible amount). Thus, the use of the chemical modification and consecutive bacterial degradation provided an effective destruction of technical PCB mixtures with a high content of highly chlorinated congeners
