The ruthenium-catalyzed synthesis of diarylmethane compounds was realized under exceedingly mild photoredox conditions without the use of exogenous photocatalysts. The versatility and robustness of the ruthenium-catalyzed C-H benzylation was reflected by an ample scope, including multifold C-H functionalizations, as well as transformable pyrazoles, imidates and sensitive nucleosides. Mechanistic studies were indicative of a photoactive cyclometalated ruthenium complex, which also enabled versatile C-H allylations.

Bretschneider, Leonore published the artcileCationically modified 6-deoxy-6-azido cellulose as a water-soluble and reactive biopolymer derivative, Product Details of C7H16ClNO2, the publication is Polymer Bulletin (Heidelberg, Germany) (2015), 72(3), 473-485, database is CAplus.

Cellulose p-toluenesulfonic acid ester was obtained by conversion of cellulose with p-toluenesulfonic acid chloride and triethylamine in N,N-dimethylacetamide/LiCl solution Further reaction with sodium azide afforded the corresponding 6-deoxy-6-azido cellulose with almost complete displacement of the sulfonate groups. Conversion of 6-deoxy-6-azido cellulose with carboxypropyltrimethylammonium chloride in the presence of N,N’-carbonyldiimidazole yielded 6-deoxy-6-azido cellulose-2,3-O-[4-(N,N,N-trimethylammonium)]butyrate chloride with the degree of substitution of cationic groups up to 0.24. Alternatively, conversion of 6-deoxy-6-azido cellulose with 4-bromobutyltrimethylammonium bromide in the presence of sodium hydroxide in 2-propanol slurry afforded 6-deoxy-6-azido-2,3-O-(4-trimethylammonium)butyl cellulose bromide with a DS of cationic groups up to 0.30. The resulting products are water soluble provided that the content of cationic groups is sufficiently high. Etherification was found to influence the d.p. much more than esterification. Utilization of DMSO and sodium hydride caused predominant polymer degradation

Pashynska, V. A. published the artcileModel mass spectrometric study of competitive interactions of antimicrobial bisquaternary ammonium drugs and aspirin with membrane phospholipids, Safety of N1,N10-Bis(2-((2-isopropyl-5-methylcyclohexyl)oxy)-2-oxoethyl)-N1,N1,N10,N10-tetramethyldecane-1,10-diaminium chloride, the publication is Biopolymers and Cell (2013), 29(2), 157-162, database is CAplus.

Aim: The aim of the study is to reveal mol. mechanisms of possible activity modulation of antimicrobial bisquaternary ammonium compounds (BQAC) and aspirin (ASP) through noncovalent competitive complexation under their combined introduction into the model systems with membrane phospholipids. Methods: Binary and triple systems containing either decamethoxinum or ethonium, or thionium and aspirin, as well as dipalmitoylphosphatidylcholine (DPPC) have been investigated by electrospray ionization mass spectrometry. Results: Basing on the anal. of associates recorded in the mass spectra, the types of nonocovalent complexes formed in the systems studied were determined and the supposed role of the complexation in the BQAC and ASP activity modulation was discussed. The formation of associates of BQA C dications with ASP anion is considered as one of the possible ways of deactivation of ionic forms of the medications. The formation of stable complexes of BQAC with DPPC and ASP with DPPC in binary systems as well as the complexes distribution in triple-components systems BQACASP:DPPC point to the existence of competition between drugs of these two types for the binding to DPPC. Conclusions: The results obtained point to the competitive complexation in the model mol. systems containing the BQAC, aspirin and membrane phospholipids. The observed phenomenon testifies to the possibility of nodularizing the activity of bisquaternary antimicrobial agents and aspirin under their combined usage, due to the competition between the drugs for binding to the target membrane phospholipid mols. and also due to the formation of stable noncovalent complexes between BQAC and ASP.

Pashynska, V. A. published the artcileDimethyl sulfoxide as a functional agent for antimicrobial drug’s transport facilitating: mechanistic study by mass spectrometry, Synthetic Route of 38146-42-8, the publication is Functional Materials (2022), 29(1), 100-106, database is CAplus.

Electrospray ionization mass spectrometry (ESI MS) study has been performed to examine biol. significant intermol. interactions between the mols. of DMSO (DMSO, known as a functional agent for transdermal and transmembrane drug’s transfer facilitation) and some antimicrobial drugs. Formation of stable noncovalent complexes of DMSO with the mols. of antibiotics levofloxacin (LEF) and cycloserine (CYS) in the polar solvent methanol has been revealed by ESI MS probing of model binary systems of DMSO with the mentioned drugs. At the same time ESI MS investigation of the similar model systems containing DMSO and antimicrobial chemotherapeutic preparation decamethoxinum (DEC) has shown that any peaks of the noncovalent complexes between DMSO and DEC are not recorded in the mass spectra, that points to the dependence of DMSO-drug complexation peculiarities on the drug’s structure. The data of ESI MS examining of DMSO+d ipalm itoylp hosphatidyl choline model system reveal that the DMSO mols. also do not form stable noncovalent clusters with the membrane phospholipid mols. in the polar surrounding. The obtained results as to formation of stable noncovalent complexes of DMSO with LEF and CYS in the polar solvent are proposed to be considered as one of the possible mol. mechanisms of action of DMSO as transdermal and transmembrane penetration enhancer in drug delivery. The current study confirms the ESI MS method applicability to examining the DMSO complexation with the drugs mole-cules and biomols. with the purpose to predict the DMSO usage efficiency as an agent for the drug’s transdermal and transmembrane transport facilitating.

Pashynska, V. A. published the artcileThe effect of cone voltage on electrospray mass spectra of the bisquaternary ammonium salt decamethoxinum, Formula: C38H74Cl2N2O4, the publication is Rapid Communications in Mass Spectrometry (2005), 20(5), 755-763, database is CAplus.

The effect of cone voltage (CV) variation on the mass spectral pattern of the bisquaternary ammonium salt decamethoxinum in the electrospray ionization (ESI) mode was studied. The advantage of decamethoxinum as a test compound in ESI mass spectrometry lies in the production of two types of precursor ions, i.e. the doubly charged organic dication Cat²⁺ and its singly charged cluster with a Cl^– counterion, Cat · Cl⁺. This makes it possible to monitor the fragmentation patterns of these ions under identical exptl. conditions. Pronounced qual. and quant. changes in the ESI mass spectra were observed upon a gradual increase of the CV. The model compound decamethoxinum allowed us to reveal the extreme situation, in which the mass spectra at a CV below and over approx. 100 V look quite different, in that they contain different product ions of Cat²⁺ and Cat · Cl⁺. While this effect may be much less pronounced for other classes of organic compounds, it should be properly taken into account for the adequate description of fragmentation pathways of bisquaternary ammonium compounds with ESI. Comparison of ESI, FAB-SIMS and MALDI mass spectra of decamethoxinum shows that taking into account CV effects also permits us to gain information on energy deposition into ions generated with the different ionization techniques.

Cardoso, David S. P. published the artcileAlkylated monoterpene indole alkaloid derivatives as potent P-glycoprotein inhibitors in resistant cancer cells, HPLC of Formula: 620-20-2, the publication is European Journal of Medicinal Chemistry (2021), 112985, database is CAplus and MEDLINE.

Aiming at generating a series of monoterpene indole alkaloids with enhanced multidrug resistance (MDR) reversing activity in cancer, two major epimeric alkaloids isolated from Tabernaemontana elegans, tabernaemontanine and dregamine, were derivatized by alkylation of the indole nitrogen. Twenty-six new derivatives were prepared by reaction with different aliphatic and aromatic halides, whose structures were elucidated mainly by NMR, including 2D NMR experiments Their MDR reversal ability was evaluated through a functional assay, using as models resistant human colon adenocarcinoma and human ABCB1-gene transfected L5178Y mouse lymphoma cells, overexpressing P-glycoprotein (P-gp), by flow cytometry. A considerable increase of activity was found for most of the derivatives, being the strongest P-gp inhibitors those sharing N-phenethyl moieties, displaying outstanding inhibitory activity, associated with weak cytotoxicity. Chemosensitivity assays were also performed in a model of combination chemotherapy in the same cell lines, by studying the in vitro interactions between the compounds and the antineoplastic drug doxorubicin. Most of the compounds have shown strong synergistic interactions with doxorubicin, highlighting their potential as MDR reversers. QSAR models were also explored for insights on drug-receptor interaction, and it was found that lipophilicity and bulkiness features were associated with inhibitory activity, although linear correlations were not observed
