The Hantzsch synthesis of novel imidazo[1,2-b]isoxazolyl-N-arylthiazolamines analogs were described. Reaction of 3-amino-5-methylisoxazole with substituted phenacyl bromides in dry ethanol afforded the corresponding 6-methyl-3-arylimidazo[1,2-b]isoxazoles in good yields. The latter compounds on reaction with chloroacetyl chloride in 1,4-dioxane furnished the corresponding 2-chloro-1-(6-methyl-3-arylimidazo[1,2-b]isoxazol-2-yl)ethanones. These compounds on heating with N-arylthioureas in an oil bath underwent cyclization to afford the title compounds viz., imidazo[1,2-b]isoxazolyl-N-arylthiazolamines in moderate to good yields by Hantzsch synthesis.

Li, Feng published the artcilePolymethylene Brushes via Surface-Initiated C1 Polyhomologation, Quality Control of 5034-06-0, the publication is Journal of the American Chemical Society (2021), 143(47), 19873-19880, database is CAplus and MEDLINE.

Surface-initiated polymerization reactions are a powerful tool to generate chain-end-tethered polymer brushes. This report presents a synthetic strategy that gives access to structurally well-defined hydrocarbon polymer brushes of controlled mol. weights, which can be further modified to generate more complex surface-attached polymer architectures. The hydrocarbon brushes reported in this study are polymethylene brushes that are obtained via surface-initiated C1 polyhomologation of dimethylsulfoxonium methylide. The strategy outlined here is based on the use of an alkylboronic acid pinacol ester initiator, which allows for controlled, unidirectional chain growth by monomer insertion into only the C-B bond of the initiator and which presents the polymerization active group at the growing polymer chain end. This surface-initiated C1 polyhomologation methodol. is compatible with photopatterning strategies and can be used to generate micropatterned polymethylene brush films. Furthermore, conversion of the boronic ester chain-end functionalities to hydroxyl groups allows for selective chain-end modification and enables access to a variety of surface-anchored block copolymer architectures by chain extension via, for example, ring-opening or atom transfer radical polymerization chemistries.

Barnash, Kimberly D. published the artcileDiscovery of Peptidomimetic Ligands of EED as Allosteric Inhibitors of PRC2, Computed Properties of 6313-54-8, the publication is ACS Combinatorial Science (2017), 19(3), 161-172, database is CAplus and MEDLINE.

The function of EED within Polycomb repressive complex 2 (PRC2) is mediated by a complex network of protein-protein interactions. Allosteric activation of PRC2 by binding of methylated proteins to EED’s aromatic cage is essential for full catalytic activity, but details of this regulation are not fully understood. EED’s recognition of the product of PRC2 activity, histone H3 lysine 27 trimethylation (H3K27me3), stimulates PRC2 methyltransferase activity at adjacent nucleosomes leading to H3K27me3 propagation and, ultimately, gene repression. By coupling combinatorial chem. and structure-based design, we optimized a low affinity methylated Jarid2 peptide to a smaller, more potent peptidomimetic ligand (Kd = 1.14 ± 0.14 μM) of the aromatic cage of EED. Our strategy illustrates the effectiveness of applying combinatorial chem. to achieve both ligand potency and property optimization. Furthermore, the resulting ligands, UNC5114 and UNC5115, demonstrate that targeted disruption of EED’s reader function can lead to allosteric inhibition of PRC2 catalytic activity.

Blake, Steven published the artcileSalicylanilide Analog Minimizes Relapse of Clostridioides difficile Infection in Mice, Product Details of C6H3ClFNO2, the publication is Journal of Medicinal Chemistry (2020), 63(13), 6898-6908, database is CAplus and MEDLINE.

Clostridioides difficile infection (CDI) causes serious and sometimes fatal symptoms like diarrhea and pseudomembranous colitis. Although antibiotics for CDI exist, they are either expensive or cause recurrence of the infection due to their altering the colonic microbiota, which is necessary to suppress the infection. Here, we leverage a class of known membrane-targeting compounds that we previously showed to have broad inhibitory activity across multiple Clostridioides difficile strains while preserving the microbiome to develop an efficacious agent. A new series of salicylanilides was synthesized, and the most potent analog was selected through an in vitro inhibitory assay to evaluate its pharmacokinetic parameters and potency in a CDI mouse model. The results revealed reduced recurrence of CDI and diminished disturbance of the microbiota in mice compared to standard-of-care vancomycin, thus paving the way for novel therapy that can potentially target the cell membrane of C. difficile to minimize relapse in the recovering patient.

Takale, Balaram S. published the artcileSustainable and Cost-Effective Suzuki-Miyaura Couplings toward the Key Biaryl Subunits of Arylex and Rinskor Active, COA of Formula: C7H7BClFO3, the publication is Organic Letters (2020), 22(12), 4823-4827, database is CAplus and MEDLINE.

Challenging Suzuki-Miyaura cross couplings associated with novel crop protection active ingredients from Corteva Agriscience, Arylex and Rinskor, can be performed in water using ppm (ppm) levels of a Pd catalyst. Each coupling required a distinct set of reaction conditions to achieve maximum selectivities and chem. yields. By way of comparison, this chem. is not only performed under environmentally responsible aqueous micellar conditions, but also involves lowering loadings (3-5 times) of endangered palladium than used previously to attain a more sustainable process.

Jamal Ahamed, V. S. published the artcileRadical polymerization of methyl methacrylate (MMA) initiated by KHSO₅-BTBAC system – a kinetic study, Name: N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Journal of Polymer Research (2012), 19(2), 1-8, database is CAplus.

Kinetics of free radical polymerization of Me methacrylate using potassium peroxomonosulfate as initiator in the presence of benzyltributylammonium chloride (BTBAC) as phase transfer catalyst was studied. The polymerization reactions were carried out under nitrogen atm. and unstirred conditions at a constant temperature of 60°C in Et acetate/water bi-phase system. The role of concentrations of monomer, initiator, catalyst, temperature, acid and ionic strength on the rate of polymerization (R_p) was ascertained. The orders with respect to monomer, initiator and phase transfer catalyst were found to be 1.5, 0.5 and 0.5 resp. The rate of polymerization (R_p) is independent of ionic strength and pH. Based on the kinetic results, a suitable mechanism is proposed.

Ciganek, M. published the artcileModification of glass capillary inner surface for chromatography, Product Details of C9H20Cl2Si, the publication is Chemical Papers (1991), 45(1), 81-9, database is CAplus.

Conditions of glass capillary (50 μm inner diameter) inner surface modification by an aqueous solution of ammonia were studied. The resulting silica gel porous layer was modified chem. by methyloctyldichlorosilane. Under given etching conditions (temperature 250-300° for 16 h), a 5-10 volume% aqueous solution of ammonia was optimal. The static way of silylation by 10 volume% silane solution in toluene for 16 h at 250-280° with the column filled to 50-70% of its volume is optimal. This method provides a mech. stable porous layer 1-10 μm thick.
