Hu, Le-Le published the artcilePredicting biological functions of compounds based on chemical-chemical interactions, Name: (3S,4R,5S)-3,4,5,6-Tetrahydroxy-2-oxohexanoic acid, the publication is PLoS One (2011), 6(12), e29491, database is CAplus and MEDLINE.

Given a compound, how can we effectively predict its biol. function. It is a fundamentally important problem because the information thus obtained may benefit the understanding of many basic biol. processes and provide useful clues for drug design. In this study, based on the information of chem.-chem. interactions, a novel method was developed that can be used to identify which of the following eleven metabolic pathway classes a query compound may be involved with: (1) Carbohydrate Metabolism, (2) Energy Metabolism, (3) Lipid Metabolism, (4) Nucleotide Metabolism, (5) Amino Acid Metabolism, (6) Metabolism of Other Amino Acids, (7) Glycan Biosynthesis and Metabolism, (8) Metabolism of Cofactors and Vitamins, (9) Metabolism of Terpenoids and Polyketides, (10) Biosynthesis of Other Secondary Metabolites, (11) Xenobiotics Biodegradation and Metabolism It was observed that the overall success rate obtained by the method via the 5-fold cross-validation test on a benchmark dataset consisting of 3,137 compounds was 77.97%, which is much higher than 10.45%, the corresponding success rate obtained by the random guesses. Besides, to deal with the situation that some compounds may be involved with more than one metabolic pathway class, the method presented here is featured by the capacity able to provide a series of potential metabolic pathway classes ranked according to the descending order of their likelihood for each of the query compounds concerned. Furthermore, our method was also applied to predict 5,549 compounds whose metabolic pathway classes are unknown. Interestingly, the results thus obtained are quite consistent with the deductions from the reports by other investigators. It is anticipated that, with the continuous increase of the chem.-chem. interaction data, the current method will be further enhanced in its power and accuracy, so as to become a useful complementary vehicle in annotating uncharacterized compounds for their biol. functions.

Ma, Guobin published the artcileMetal catalyst-free photo-induced alkyl C-O bond borylation, Synthetic Route of 608534-44-7, the publication is Chemical Communications (Cambridge, United Kingdom) (2020), 56(70), 10219-10222, database is CAplus and MEDLINE.

Metal catalyst free, blue visible light-induced C-O bond borylation of unactivated tertiary alkyl Me oxalates was developed to furnish tertiary alkyl boronates. From the secondary alcs. activated with imidazolylthionyl, moderate yields of boronates were attained under standard photo-induced conditions. Preliminary mechanistic studies confirmed the involvement of a (DMF)₂-B₂cat₂ adduct that weakly absorbs light at 437 nm so as to initiate a Bcat radical. A radical-chain process is proposed wherein the alkyl radical is engaged.

Wang, Le-Cheng published the artcileNickel-Catalyzed Four-Component Carbonylation of Ethers and Olefins: Direct Access to γ-Oxy Esters and Amides, Product Details of C12H20O6, the publication is Angewandte Chemie, International Edition (2022), 61(33), e202207970, database is CAplus and MEDLINE.

Multi-component carbonylation of olefins, a reaction that installs both a carbon-carbon(heteroatom) bond and a carbonyl group across the double bond, is an attractive strategy for alkene functionalization. Herein, a novel nickel-catalyzed four-component carbonylation of olefins with ethers under low CO gas pressure is developed. Using alcs. and amines as the reaction partner, diverse γ-oxy-substituted esters and amides were produced in good yields with excellent functional group tolerance. Notably, Naftidrofuryl, a medicine for the treatment of cerebrovascular disease (CVD), can be synthesized by this process straightforwardly.

Peng, Huige published the artcileReprogramming Tumor-Associated Macrophages To Reverse EGFR^T790M Resistance by Dual-Targeting Codelivery of Gefitinib/Vorinostat, Synthetic Route of 96345-79-8, the publication is Nano Letters (2017), 17(12), 7684-7690, database is CAplus and MEDLINE.

Gefitinib is a first-line therapy in the EGFR-mutated nonsmall cell lung cancer (NSCLC). However, the development of drug resistance is almost unavoidable, thus leading to an unsustainable regimen. EGFR^T790M mutation is the major cause responsible for the mol.-targeting therapy failure in NSCLC. Although the recently approved osimertinib is effective for the EGFR^T790M-pos. NSCLC, the osimertinib-resistant EGFR mutation is rapidly developed, too. In this study, we proposed a tumor-associated macrophage (TAM) reprogramming strategy for overcoming the EGFR^T790M-associated drug resistance via a dual-targeting codelivery system of gefitinib/vorinostat that acted on both TAM with overexpression of mannose receptors and the HER-2 pos. NSCLC cells. The trastuzumab-modified, mannosylated liposomal system was able to repolarize the protumor M2 phenotype to the antitumor M1 and cause the elevating ROS in the cancer cells, consequently modulating the intracellular redox balance via ROS/NOX3/MsrA axis. The suppressed MsrA facilitated the EGFR^T790M degradation through 790M oxidation by ROS, thus resensitizing the EGFR^T790M-pos. cells to gefitinib. The dual-targeting codelivery and TAM-reprogramming strategies provided a potential method for rescuing the EGFR^T790M-caused resistance to tyrosine kinase inhibitor treatment.

Jadhav, Sandip B. published the artcileDiastereoselective Desymmetrization of p-Quinamines through Regioselective Ring Opening of Epoxides and Aziridines, SDS of cas: 57044-25-4, the publication is Organic Letters (2019), 21(24), 10115-10119, database is CAplus and MEDLINE.

A highly diastereoselective desymmetrization of p-quinamines via regioselective ring opening of epoxides and aziridines under mild conditions has been developed. A chairlike six-membered transition state with minimized 1,3-diaxial interactions explains the relative stereoselectivity of the cyclization reaction. This transition-metal free [3 + 3] annulation reaction provides rapid access to fused bicyclic morpholines and piperazines with a tetrasubstituted carbon center in high yields. In addition, it also allows the synthesis of enantioenriched products by using easily accessible chiral nonracemic epoxides and aziridines.

Youenou, Benjamin published the artcileIn vitro study to evaluate the antimicrobial activity of various multifunctional cosmetic ingredients and chlorphenesin on bacterial species at risk in the cosmetic industry, Computed Properties of 70445-33-9, the publication is Journal of Applied Microbiology (2022), 132(2), 933-948, database is CAplus and MEDLINE.

We evaluated the activity of the preservative chlorphenesin and of four antimicrobial cosmetic multifunctional ingredients against various strains of gram-neg. and gram-pos. human opportunistic pathogens. Growth kinetics, modeling growth parameters and statistical analyses enabled comparing bacterial behavior in the presence and in the absence of the compound Whatever compound tested (i.e. chlorphenesin, phenylpropanol, hexanediol, ethylhexylglycerin, hydroxyacetophenone) and strain origin (i.e. clin. vs. industrial), the growth of 42 strains belonging to Acinetobacter spp., Burkholderia cepacia complex and Stenotrophomonas maltophilia, was totally inhibited. On the opposite all of the P. aeruginosa strains (n = 13) as well as 4 and 6 out of 10 strains of Pluralibacter gergoviae grew in the presence of chlorphenesin and ethylhexylglycerin, resp. Some P. gergoviae and Staphylococcus hominis strains withstand hydroxyacetophenone. Within a species, the different strains show variable latency phase, growth rate (r) and carrying capacity (K). They can be similar, lower or higher than those measured in control conditions. Data showed differences in the antimicrobial activity of compounds Upon exposure, strains differed in their behavior between and within species. Whatever species and strains, compound sensitivity could not be related to antibiotic resistance. Most multifunctional ingredients showed significant antimicrobial properties against the wide panel of species and strains evaluated. This will help adjusting preservation strategies in the cosmetic industry.

Rout, Kanhu Charan published the artcileA copper(II) complex as selective turn-on fluorosensor for nitric oxide and its intracellular application, Category: alcohols-buliding-blocks, the publication is Inorganica Chimica Acta (2015), 201-206, database is CAplus.

A highly water soluble copper(II) complex, 1 of a fluorophore ligand 4-(2-hydroxybenzylamino)-5-hydroxynaphthalene-2,7-disulfonic acid (FL₁) was synthesized and characterized. In the complex, the fluorescence intensity of the ligand was found to quench due to the presence of paramagnetic Cu(II) center. In degassed methanol solution of complex 1, the Cu(II) center was found to undergo reduction in presence of nitric oxide. This resulted in the simultaneous formation of N-nitrosated ligand. In the process, the quenched fluorescence intensity of the ligand restored. The selective turn on fluorogenic nature of the complex 1 was used to study the endogenously produced NO in living cells.

Chatterjee, Maya published the artcileProduction of lactic acid mediated by compressed carbon dioxide on heterogeneous Ni(II) catalysts: a facile approach, Application of 2-Hydroxy-2-phenylacetic acid, the publication is Green Chemistry (2022), 24(16), 6145-6155, database is CAplus.

Lactic acid is one of the appealing platform mols. in organic synthesis, currently in high demand after the innovation of bio-plastics. The limitations of traditional manufacturing routes (microbial process and chem. synthesis using petroleum resources) directed us to develop economically and environmentally viable catalytic strategies exploring renewable resources to meet the expected demand. In this study, we demonstrated a method of lactic acid synthesis by fixing CO₂ as a waste gas into acetaldehyde used as a biobased feedstock on a highly active, recyclable heterogeneous Ni catalyst. The significance of the developed process lies in the transformation of easily available low-cost starting materials to a high-value product without harsh reaction conditions, extra sensitive reagents, and addnl. steps to derive the right starting material or to remove impurities, which is advantageous in terms of sustainability. Moreover, the optimization of different reaction parameters ensures achieving high yields (>80%) and an excellent production rate of 6700μmol g^-1 h^-1. In addition, the characterization of the catalyst by different spectroscopic techniques suggested an interaction between the substrate and the catalyst, which provides an indication of the possible reaction path, thus a mechanism would be outlined. The successful extension of this process to various aldehydes was possible to produce their corresponding hydroxycarboxylic acid with broad functional group tolerance. Altogether, this methodol. opens up a promising avenue for the production of biochems. from renewable resources, which is a key to develop a sustainable society.
