The rearrangement of aldoximes to primary amides has been studied using the com. available bis(allyl)-ruthenium(IV) complex [{RuCl(μ-Cl)(η³:η³-C₁₀H₁₆)}₂] (1; C₁₀H₁₆ = 2,7-dimethylocta-2,6-diene-1,8-diyl) as a catalyst under thermal and microwave heating. The reactions proceeded cleanly in a mixture of water/glycerol (1:1) at 120-150°, without the assistance of any cocatalyst, affording the desired amides in moderate to high yields and short times. The process was operative with aromatic, heteroaromatic, aliphatic, and α,β-unsaturated aldoximes and tolerated the presence of several functional groups in the substrates. In addition, the recyclability of catalyst 1 (up to six consecutive runs) could be demonstrated.

Li, Ze-lin published the artcilePd/Ni catalyzed selective N-H/C-H methylation of amides by using peroxides as the methylating reagents via a radical process, COA of Formula: C7H8FNO2S, the publication is Organic Chemistry Frontiers (2017), 4(11), 2207-2210, database is CAplus.

A palladium/nickel catalyzed selective N-H/C-H methylation of amides such as benzenesulfonamide, nicotinamide, benzamide, etc. by using peroxides to provide N-methylation products such as N-methylbenzenesulfonamide, N-methylnicotinamide, N-methylbenzamide, etc. and C-methylation products such as 2-methylbenzenesulfonamide, 2-methylnicotinamide, 2-methylbenzamide, etc. in moderate to good yields was described. In this procedure, peroxides play a dual role, serving as both the Me source and radical initiator. This protocol tolerated a broad range of substrates, not only various sulfonamides but also methanamides. Mechanistic investigations involving a radical process are also described.

Blencowe, Anton published the artcileSynthesis of hyperbranched poly(aryl ether)s via carbene insertion processes, Category: amides-buliding-blocks, the publication is Macromolecules (2007), 40(4), 939-949, database is CAplus.

Homopolymerization of alkylaryl carbenes derived from diazirine monomers that featured benzyl alc. or phenol residues was found to lead to the production of soluble hyperbranched poly(aryl ether)s. The polymerization process was influenced by the solvents employed, monomer concentration, and the reaction time. An increase in the monomer concentration and reaction time was found to lead to an increase in the mol. weight characteristics of the resulting polymers as determined by gel permeation chromatog. (GPC). The composition and architecture of the polyethers were determined by NMR spectroscopic anal. and were found to be highly complex and dependent on the structure of the monomers used. All of the polymers were found to contain ether linkages formed via carbene insertion into O-H bonds, although polymers derived from phenolic carbenes also contained linkages arising from C-alkylation.

Melting temperatures of DNA duplexes containing the phenoxazine (P) and G-clamp (X) cytosine analogs exhibited a strong and unusual dependence on the nucleoside flanking the modified nucleobase, and the same trend was observed in PNA-DNA duplexes incorporating X in the PNA chain. Mol. dynamics simulations of the DNA duplexes show that generalized stacking (including secondary interactions of the ammonium group of X) and hydrogen bonding are good descriptors of the different duplex stabilities.

Trobe, Melanie published the artcileA modular synthesis of teraryl-based α-helix mimetics, part 4: Core fragments with two halide leaving groups featuring side chains of proteinogenic amino acids, Recommanded Product: 2-Chloroacetamide, the publication is European Journal of Organic Chemistry (2022), 2022(17), e202101279, database is CAplus and MEDLINE.

Teraryl-based α-helix mimetics have proven to be useful compounds for the inhibition of protein-protein interactions (PPI). We have developed a modular and flexible approach for the synthesis of teraryl-based α-helix mimetics using a benzene core unit featuring two halide leaving groups of differentiated reactivity in the Pd-catalyzed cross-coupling used for teraryl assembly. The use of para-bromo iodoarene core fragments resolved the issue of hydrolysis during cross-coupling that was observed when using triflate as a leaving group. We report a complete set of para-bromoiodoarene core fragments decorated with side chains of all proteinogenic amino acids relevant for PPI (Ala, Arg, Asn, Asp, Cys, Gln, Glu, His, Ile, Leu, Lys, Met, Phe, Ser, Thr, Trp, Tyr and Val). In order to be compatible with general cross-coupling conditions, some of the nucleophilic side chains had to be provided in a protected form to serve as stable building blocks.

Tambe, Suparna published the artcileStructure-performance relationships of phenyl cinnamic acid derivatives as MALDI-MS matrices for sulfatide detection, Related Products of amides-buliding-blocks, the publication is Analytical and Bioanalytical Chemistry (2017), 409(6), 1569-1580, database is CAplus and MEDLINE.

A key aspect for the further development of matrix-assisted laser desorption ionization (MALDI)-mass spectrometry (MS) is a better understanding of the working principles of MALDI matrixes. To address this issue, a chem. compound library of 59 structurally related cinnamic acid derivatives was synthesized. Potential MALDI matrixes were evaluated with sulfatides, a class of anionic lipids which are abundant in complex brain lipid mixtures For each matrix relative mean S/N ratios of sulfatides were determined against 9-aminoacridine as a reference matrix using neg. ion mass spectrometry with 355 and 337 nm laser systems. The comparison of matrix features with their corresponding relative mean S/N ratios for sulfatide detection identified correlations between matrix substitution patterns, their chem. functionality, and their MALDI-MS performance. Crystal structures of six selected matrixes provided structural insight in hydrogen bond interactions in the solid state. Principal component anal. allowed the addnl. identification of correlation trends between structural and phys. matrix properties like number of exchangeable protons at the head group, MW, logP, UV-Vis, and sulfatide detection sensitivity.

The high affinity leukotriene B₄ receptor, BLT1 mediates chemotaxis of diverse leukocyte subsets to the sites of infection or inflammation. Whereas the pathol. functions of LTB₄/BLT1 axis in allergy, autoimmunity and cardiovascular disorders are well established; its role in cancer is only beginning to emerge. In this review, we summarize recent findings on LTB₄/BLT1 axis enabling distinct outcomes toward tumor progression. In a mouse lung tumor model promoted by silicosis-induced inflammation, genetic deletion of BLT1 attenuated neutrophilic inflammation and tumor promotion. In contrast, in a spontaneous model of intestinal tumorigenesis, absence of BLT1 led to defective mucosal host response, altered microbiota and bacteria dependent colon tumor progression. Furthermore, BLT1 mediated CD8⁺ T cell recruitment was shown to be essential for initiating anti-tumor immunity in number of xenograft models and is critical for effective PD1 based immunotherapy. BLT2 mediated chemotherapy resistance, tumor promotion and metastasis are also discussed. This new information points to a paradigm shift in our understanding of the LTB₄ pathways in cancer.

Gless, Bengt H. published the artcileIdentification of autoinducing thiodepsipeptides from staphylococci enabled by native chemical ligation, Name: H-Lys(Boc)-OH, the publication is Nature Chemistry (2019), 11(5), 463-469, database is CAplus and MEDLINE.

Staphylococci secrete autoinducing peptides (AIPs) as signaling mols. to regulate population-wide behavior. AIPs from non-Staphylococcusaureus staphylococci have received attention as potential antivirulence agents to inhibit quorum sensing and virulence gene expression in the human pathogen Staphylococcus aureus. However, only a limited number of AIP structures from non-S. aureus staphylococci have been identified to date, as the minute amounts secreted in complex media render it difficult. Here, we report a method for the identification of AIPs by exploiting their thiolactone functionality for chemoselective trapping and enrichment of the compounds from the bacterial supernatant. Standard liquid chromatog. mass spectrometry anal., guided by genome sequencing data, then readily provides the AIP identities. Using this approach, we confirm the identity of five known AIPs and identify the AIPs of eleven non-S. aureus species, and we expect that the method should be extendable to AIP-expressing Gram-pos. bacteria beyond the Staphylococcus genus.
