Britten, Collin N.;Lason, Kristen;Walters, Keisha B. research published 《 Facile Synthesis of Tertiary Amine Pendant Polymers by Cu⁰-Mediated ATRP under Aqueous Conditions》, the research content is summarized as follows. Cu⁰-mediated atom transfer radical polymerization (ATRP) in aqueous media is extended to tertiary amine-pendant methacrylate polymers with poly([2-dimethylamino]ethyl methacrylate) (PDMAEMA) serving as a model polymer. By increasing concentration of deactivating Cu^II species, reducing reaction temperature, and increasing supporting halide concentration to 1 M, polymers with well-defined mol. weight distributions (MWDs) are achieved in under 4 h. MWDs show good agreement with theor. values, with polydispersity indexes (D) as low as 1.14. Furthermore, this reaction system shows a remarkable tolerance to dissolved oxygen, with little to no deleterious effects observed for polymerizations run without degassing prior to initiation. Syntheses at mildly acidic pH of 3.5 demonstrate excellent retention of active end groups as demonstrated by chain extensions at near-quant. conversion and extends the system to 2-(diethylamino)ethyl methacrylate (DEAEMA) and 2-(diisopropyl)ethyl methacrylate (DPAEMA). This work presents a new aqueous method for the rapid and facile synthesis of tertiary amine-pendant polymers with well-defined MWDs.

Buerger, Marcel;Ehrhardt, Nadine;Barber, Thomas;Ball, Liam T.;Namyslo, Jan C.;Jones, Peter G.;Werz, Daniel B. research published 《 Phosphine-Catalyzed Aryne Oligomerization: Direct Access to α,ω-Bisfunctionalized Oligo(ortho-arylenes)》, the research content is summarized as follows. A phosphine-catalyzed oligomerization of arynes using selenocyanates was developed. The use of JohnPhos as a bulky phosphine is the key to accessing α,ω-bisfunctionalized oligo(ortho-arylenes) with RSe as substituent at one terminus and CN as substituent at the other. The in situ formation of R₃PSeR’ cations, serving as sterically encumbered electrophiles, hinders the immediate reaction that affords the 1,2-bisfunctionalization product and instead opens a competitive pathway leading to oligomerization. Various optimized conditions for the predominant formation of dimers, but also for higher oligomers such as trimers and tetramers, were developed. Depending on the electronic properties of the electrophilic reaction partner, even compounds up to octamers were isolated. Optimization experiments revealed that a properly tuned phosphine as catalyst is of crucial importance. Mechanistic studies demonstrated that the cascade starts with the attack of cyanide; aryne insertion into n-mers leading to (n+1)-mers was ruled out.

It is an inhibitor of γ-secretase, which is responsible for cleaving the amyloid precursor protein (APP), and it has shown efficacy against biphenyl, an anticancer drug that binds to benzodiazepine receptors. 2-Bromophenylboronic acid is also an enantiopure compound because all four substituents are different from each other., 244205-40-1.

Barsbay, Murat;Caylan Ozgur, Tansu;Sutekin, S. Duygu;Guven, Olgun research published 《 Effect of brush length of stabilizing grafted matrix on size and catalytic activity of metal nanoparticles》, the research content is summarized as follows. The rationale of this work is to investigate the effect of chain length of stabilizing polymer brushes attached to silica surface on the formation and catalytic activity of metallic palladium nanoparticles (Pd NPs). Poly(vinyl pyrrolidone) (PVP) brushes forming a very thin shell were grafted on silica microparticles (PVP@SiO₂) via RAFT mediated graft polymerization, thus controlling the mol. weights and structures of PVP grafts. Pd nanoparticles were formed in PVP stabilizing matrix by gamma-induced reduction of polymer-bound Pd(II) ions to yield Pd(0) decorated core-shell particles (PVP-PdNP@SiO₂). SEC and TGA results indicated the formation of PVP brushes with different mol. weights on silica substrate. DLS and TEM measurements revealed that particle growth was sterically blocked by the increase in PVP brush length, thereby forming a greater number of small Pd nanoparticles rather than larger ones. PVP-PdNP@SiO₂ samples with different PVP chain lengths and Pd sizes were evaluated for their catalytic activity and reusability in the reduction of 4-nitrophenol to 4-aminophenol. Although the nanoparticles formed in the presence of longer grafted chains are smaller, their leakage into the solution has been found to be more effectively prevented by these long grafts. Thus, PVP-PdNP@SiO₂ samples with longer PVP grafts showed more stable catalytic activity in repeated reaction cycles. These findings are particularly important for heterogeneous catalysis systems in that they show the effect of the size of surface-bound polymeric stabilizers on metal NP formation and catalytic activity.

The 3,9-diazaspiro[5.5]undecane-based compounds 2027 and 018 have previously been reported to be potent competitive γ-aminobutyric acid type A receptor (GABA_AR) antagonists showing low cellular membrane permeability. Given the emerging peripheral application of GABA_AR ligands, we hypothesize 2027 analogs as promising lead structures for peripheral GABA_AR inhibition. We herein report a study on the structural determinants of 2027 in order to suggest a potential binding mode as a basis for rational design. The study identified the importance of the spirocyclic benzamide, compensating for the conventional acidic moiety, for GABA_AR ligands. The structurally simplified m-methylphenyl analog 1e displayed binding affinity in the high-nanomolar range (K_i = 180 nM) and was superior to 2027 and 018 regarding selectivity for the extra synaptic α₄βδ subtype vs. the α₁– and α₂– containing subtypes. Importantly, 1e was shown to efficiently rescue inhibition of T cell proliferation, providing a platform to explore the immunomodulatory potential for this class of compounds

Bayaraa, Tenuun;Kurz, Julia L.;Patel, Khushboo M.;Hussein, Waleed M.;Bilyj, Jessica K.;West, Nicholas P.;Schenk, Gerhard;McGeary, Ross P.;Guddat, Luke W. research published 《 Discovery, Synthesis and Evaluation of a Ketol-Acid Reductoisomerase Inhibitor》, the research content is summarized as follows. Ketol-acid reductoisomerase (KARI), the second enzyme in the branched-chain amino acid biosynthesis pathway, is a potential drug target for bacterial infections including Mycobacterium tuberculosis. Here, we have screened the Medicines for Malaria Venture Pathogen Box against purified M. tuberculosis (Mt) KARI and identified two compounds that have K_i values below 200 nM. In Mt cell susceptibility assays one of these compounds exhibited an IC₅₀ value of 0.8μm. Co-crystallization of this compound, 3-((methylsulfonyl)methyl)-2H-benzo[b][1,4]oxazin-2-one (MMV553002), in complex with Staphylococcus aureus KARI, which has 56% identity with Mt KARI, NADPH and Mg²⁺ yielded a structure to 1.72 Å resolution However, only a hydrolyzed product of the inhibitor (i.e. 3-(methylsulfonyl)-2-oxopropanic acid, missing the 2-aminophenol attachment) is observed in the active site. Surprisingly, Mt cell susceptibility assays showed that the 2-aminophenol product is largely responsible for the anti-TB activity of the parent compound Thus, 3-(methylsulfonyl)-2-oxopropanic acid was identified as a potent KARI inhibitor that could be further explored as a potential biocidal agent and we have shown 2-aminophenol, as an anti-TB drug lead, especially given it has low toxicity against human cells. The study highlights that careful anal. of broad screening assays is required to correctly interpret cell-based activity data.
