Mitini-Nkhoma, Steven C. published the artcileIon transport modulators differentially modulate inflammatory responses in THP-1-derived macrophages, Recommanded Product: trans-4-((2-Amino-3,5-dibromobenzyl)amino)cyclohexanol hydrochloride, the publication is Journal of Immunology Research (2021), 8832586, database is CAplus and MEDLINE.

Ion transport modulators are most commonly used to treat various noncommunicable diseases including diabetes and hypertension. They are also known to bind to receptors on various immune cells, but the immunomodulatory properties of most ion transport modulators have not been fully elucidated. We assessed the effects of thirteen FDA-approved ion transport modulators, namely, ambroxol HCl, amiloride HCl, diazoxide, digoxin, furosemide, hydrochlorothiazide, metformin, omeprazole, pantoprazole, phenytoin, verapamil, drug X, and drug Y on superoxide production, nitric oxide production, and cytokine expression by THP-1-derived macrophages that had been stimulated with ethanol-inactivated Mycobacterium bovis BCG. Ambroxol HCl, diazoxide, digoxin, furosemide, hydrochlorothiazide, metformin, pantoprazole, phenytoin, verapamil, and drug Y had an inhibitory effect on nitric oxide production, while all the test drugs had an inhibitory effect on superoxide production Amiloride HCl, diazoxide, digoxin, furosemide, phenytoin, verapamil, drug X, and drug Y enhanced the expression of IL-1β and TNF-α. Unlike most immunomodulatory compounds currently in clin. use, most of the test drugs inhibited some inflammatory processes while promoting others. Ion pumps and ion channels could therefore serve as targets for more selective immunomodulatory agents which do not cause overt immunosuppression.

Pagola, G. I. published the artcileCould Electronic Anapolar Interactions Drive Enantioselective Syntheses in Strongly Nonuniform Magnetic Fields? A Computational Study, COA of Formula: C3H6O2, the publication is Journal of Chemical Theory and Computation, database is CAplus and MEDLINE.

It is shown that the anapolar interaction of the electrons of a mol. with an external uniform magnetic field B and a uniform curl C = ∇ × B′ determines different thermodn. stabilization of the ground state for the enantiomers and diastereoisomers of a chiral mol. A series of potential candidates for enantioselective syntheses have been investigated in a computational study via SCF-HF, B3LYP, and various coupled cluster approaches to determine the difference in energy between different enantiomers and diastereoisomers. The calculations show that these differences are very small for B and C presently available but approx. 3 orders of magnitude larger than those determined by parity violation effects. The chances that enantioselective synthesis may be attempted in the future are discussed. Recognition of anapolar interaction in chiral mols. via measurements of an induced magnetic dipole moment in the ordered phase may become possible in the presence of a nonuniform magnetic field with a strong gradient.

Martins, Marcia S. published the artcileOccurrence of Allergens in Cosmetics for Sensitive Skin, Quality Control of 111-29-5, the publication is Cosmetics (2022), 9(2), 32, database is CAplus.

Sensitive skin is characterized by symptoms such as stinging and tingling in response to stimuli that usually do not cause unpleasant sensations. Epidemiol. studies show that individuals with sensitive skin are more prone to developing skin allergies, although the link between both conditions is unknown. Aiming to evaluate the presence of allergens in facial-skin products for sensitive skin, a pool of 88 cosmetic products from international brands marketed in pharmacies and parapharmacies was analyzed. A list of allergens identified in product labels was compiled and grouped according to their function. Fragrances were the most common allergens, followed by skin-conditioning agents, surfactants, and preservatives. Fragrances presenting the highest use percentages were linalool, benzyl alc., geraniol, and citronellol. Overall, the majority of cosmetic formulations were absent of fragrance allergens, being present only in 7% of products. Other allergens were found in most products (95%). This finding should be interpreted with caution, since many of these compounds are rare sensitizers and studies demonstrating their risk for individuals with sensitive skin are lacking. With this study, useful information for health professionals is provided to support their advice and to help consumers choosing cosmetic products.

Macchi, Marianela published the artcileAssessing interactions, predicting function, and increasing degradation potential of a PAH-degrading bacterial consortium by effect of an inoculant strain, Related Products of alcohols-buliding-blocks, the publication is Environmental Science and Pollution Research (2019), 26(25), 25932-25944, database is CAplus and MEDLINE.

A natural phenanthrene-degrading consortium CON was inoculated with an exogenous strain Sphingobium sp. (ex Sp. paucimobilis) 20006FA yielding the consortium called I-CON, in order to study ecol. interactions into the bacterial community. DGGE and proteomic profiles and analyses by HTS (High-Throughput Sequencing) technologies demonstrated inoculant establishment and changes on CON composition Inoculation increased degradation efficiency in I-CON and prevented intermediate HNA accumulation. This could be explained not only by the inoculation, but also by enrichment in Achromobacter genus at expense of a decrease in Klebsiella genus. After inoculation, cooperation between Sphingobium and Achromobacter genera were improved, thereby, some competition could have been generated, and as a consequence, species in minor proportion (cheaters), as Inquilinus sp. and Luteibacter sp., were not detected. Sequences of Sphingobium (corresponding to the inoculated strain) did not vary. PICRUSt predicted a network with bacterial phylotypes connected with enzymes, showing functional redundancy in the phenanthrene pathway, with exception of the first enzymes biphenyl-2,3-diol 1,2-dioxygenase and protocatechuate 4,5-dioxygenase that were only encoded in Sphingobium sp. This is the first report where a natural consortium that has been characterized by HTS technologies is inoculated with an exogenous strain in order to study competitiveness and interactions.

Macchi, Marianela published the artcileDesign and evaluation of synthetic bacterial consortia for optimized phenanthrene degradation through the integration of genomics and shotgun proteomics, Formula: C11H8O3, the publication is Biotechnology Reports (2021), e00588, database is CAplus and MEDLINE.

Two synthetic bacterial consortia (SC) composed of bacterial strains Sphingobium sp. (AM), Klebsiella aerogenes (B), Pseudomonas sp. (Bc-h and T), Burkholderia sp. (Bk) and Inquilinus limosus (Inq) isolated from a natural phenanthrene (PHN)-degrading consortium (CON) were developed and evaluated as an alternative approach to PHN biodegradation in bioremediation processes. A metabolic network showing the potential role of strains was reconstructed by in silico study of the six genomes and classification of dioxygenase enzymes using RHObase and AromaDeg databases. Network anal. suggested that AM and Bk were responsible for PHN initial attack, while Inq, B, T and Bc-h would degrade PHN metabolites. The predicted roles were further confirmed by physiol., RT-qPCR and metaproteomic assays. SC-1 with AM as the sole PHN degrader was the most efficient. The ecol. roles inferred in this study can be applied to optimize the design of bacterial consortia and tackle the biodegradation of complex environmental pollutants.

Paul, Aparup published the artcileDouble μ₂-(phenoxido)-bridged dinuclear and polynuclear nickel(II) complexes: Magnetic properties and DNA/protein interaction, Category: alcohols-buliding-blocks, the publication is Polyhedron (2019), 39-48, database is CAplus.

One dinuclear and one 1-dimensional polymeric Ni(II) complex, {[Ni₂(HL)₂(pa)₂(H₂O)₂]·DMF} (1) and {[Ni₂(HL)₂(ppda)(H₂O)₂]·DMF·H₂O}_n (2) (H₂L = (E)-2-((1-hydroxybutan-2-ylimino)methyl)phenol, pa = 3-phenylacrylate, ppda = p-phenylenediacrylate) were synthesized and characterized by x-ray single crystal structure determination Complex 1 is double phenoxo-bridged dinuclear Ni(II) complex, whereas complex 2 is a 1-dimensional polynuclear chain where double phenoxo-bridged dinuclear units are connected through bridging ppda ligands. The variable temperature magnetic behavior of the complexes was studied using the Hamiltonian H = -JS₁S₂, S₁ = S₂ = S_Ni and confirms the presence of an overall antiferromagnetic interaction in both complexes. Good agreement between the exptl. and simulated curves were found using the parameters: g_Ni = 2.15, D_Ni = 4.0 cm^-1 and J_Ni-Ni = -0.60 cm^-1 for 1, and g_Ni = 2.15, D_Ni = 4.8 cm^-1 and J_Ni-Ni = -3 cm^-1 for 2. The interactions of the complexes with CT-DNA were studied using UV-visible absorption and fluorescence spectroscopic methods and both the complexes interact with CT-DNA. The intrinsic binding constants values for interaction with CT-DNA are 3.9(±0.10) × 10⁵ and 3.43(±0.09) × 10⁵ M^-1 for 1 and 2, resp. The interactions of the complexes with bovine serum albumins (BSA) and human serum albumins (HSA) were also studied using electronic absorption and fluorescence spectroscopic techniques and both complexes interact with the serum albumins via a ground state association process.

Higgins, Clare L. published the artcileSynthesis, characterisation, and performance evaluation of tri-armed phenolic antioxidants, Product Details of C9H21NO3, the publication is Tetrahedron Letters (2020), 61(28), 152127, database is CAplus.

In this study, a series of core units (glycerol, triethanolamine and triisopropanolamine derivatives) were investigated for their use in tri-armed phenolic antioxidants. The antioxidant ability of these tri-armed phenolic compounds featuring different core units were then evaluated in a hydrocarbon lubricant using differential scanning calorimetry (DSC) and compared to the com. available antioxidants Irganox L135 and Irganox L57. An impressive oxidation induction time of ∼9-12 min was observed for the glycerol based antioxidants when compared to the com. antioxidants (∼4-6 min), whereas in contrast in the case of triethanolamine and triisopropanolamine derived antioxidants, a solubilizing unit was incorporated to provide appropriate solubility within the hydrocarbon medium and revealed an excellent oxidation induction time of ∼11-12 min.

Bettinger, Holger F. published the artcileMetal-free conversion of methane and cycloalkanes to amines and amides by employing a borylnitrene, Synthetic Route of 25240-59-9, the publication is Angewandte Chemie, International Edition (2008), 47(25), 4744-4747, database is CAplus and MEDLINE.

C-H insertion: Borylnitrenes, which were generated in situ by photolysis of azides, convert unactivated alkanes by intermol. C-H insertion into aminoboranes, which in turn can be reacted further to give amines or amides. The boryl group serves two purposes: it converts the nitrene into a highly reactive BN vinylidene analog, and it is easily cleaved from the product. Caution: B azides may be explosive, and appropriate precautions must be taken when handling these compounds To study the reaction of catechol borylnitrene (C₆H₄O₂BN:, 1a) with methane, the authors isolated 2-azido-1,3,2-benzodioxaborole (C₆H₄O₂BN₃, 3a) in Ar doped with methane (1-2% CH₄ or CD₄) at 10 K. Photolysis of 3a using UV irradiation resulted in the complete disappearance of 3a, the concomitant formation of nitrene C₆H₄O₂BN: (1a) and of aminoborane C₆H₄O₂BN(H)Me (2a) according to IR spectra and DFT calculations of vibrational modes. Reaction of trimethylsilyl azide and 2-chloro-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (pinacolboron chloride (pinBCl)) gave 2-azido-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (3b, pinacolboron azide (pinBN₃)) in 96% yield. Photolysis of 3b in cycloalkane solutions at room temperature afforded the expected aminoboranes pinBN(H)R (R = cyclopentyl, cyclohexyl, cycloheptyl) in 79% to 85% yield. The aminoboranes can conveniently be transformed into the corresponding primary amines or amides by alcoholysis or acylation, resp. The mol. structures of pinBN(H)R (R = cyclopentyl, cyclohexyl) were determined by x-ray crystallog.
