Sen, Partha Pratim;Roy, Vishal Jyoti;Raha Roy, Sudipta research published 《 Metal-free regioselective bromination of imidazo-heteroarenes: the dual role of an organic bromide salt in electrocatalysis》, the research content is summarized as follows. An electrochem. transformation was represented by demonstrating the dual role of an organic bromide salt, i.e., tetra-n-butylammonium bromide (TBAB), as a brominating agent and as an electrolyte for the regioselective bromination of several imidazo heteroaromatic motifs, e.g., I. Instead of using a transition metal/external oxidant, this methodol. utilized electron holes and electrons by means of anodic oxidation and cathodic reduction to form the desired products in good to excellent yields at ambient temperature The method was simple, environment friendly and compatible with various functional groups. The significance of this sustainable greener bromination technique relies on the fact that the readily available cost-effective electrodes (C(+)/C(-)) could be reused up to forty times without loss of any electrochem. activities. The electro-oxidative method could efficiently be scaled up and can be extended to chlorination as well. Moreover, this electro-synthetic strategy was extrapolated to the domino organo-electrochem. bromination technique for the synthesis of a brominated imidazo heteroaromatic moiety directly starting from substituted 2-bromoacetophenone and 2-aminopyridine by using catalytic amounts of electrolyte.

Sebris, Armands;Novosjolova, Irina;Traskovskis, Kaspars;Kokars, Valdis;Tetervenoka, Natalija;Vembris, Aivars;Turks, Maris research published 《 Photophysical and Electrical Properties of Highly Luminescent 2/6-Triazolyl-Substituted Push-Pull Purines》, the research content is summarized as follows. New push-pull N(9)-alkylated 6-piperidino-2-triazolylpurine and 2-piperidino-6-triazolylpurine derivatives are synthesized, and their optical and optoelectronic properties are comprehensively characterized with exptl. and computational methods. The compounds possess intense violet or blue fluorescence with fluorescence quantum yields of up to 91% in solution and 40% in host-free films. Depending on their structural composition, the compounds have ionization energy in the range of 5.25-6.04 eV, electron affinity of 2.18-3.15 eV, and triplet energy of 2.52-2.95 eV. Due to the presence of hole-transporting purine and electron-transporting triazole fragments, compounds exhibit bipolar charge-transportation ability. Despite the favorable emissive properties of the studied push-pull purines, their electroluminescence in thin films is quenched owing to large current densities that are present even at a moderate driving voltage. This marks application directions related to a predominantly charge-transportation functionality as the most suitable for this compound class.

The profound efficacy, yet associated toxicity of pan-BET inhibitors is well documented. The possibility of an ameliorated safety profile driven by significantly selective (>100-fold) inhibition of a subset of the eight bromodomains is enticing, but challenging given the close homol. Herein, we describe the X-ray crystal structure-directed optimization of a novel weak fragment ligand with a pan-second bromodomain (BD2) bias, to potent and highly BD2 selective inhibitors. A template hopping approach, enabled by our parallel research into an orthogonal template (15, GSK046, I), was the basis for the high selectivity observed This culminated in two tool mols., 20 (GSK620) and 56 (GSK549), which showed an anti-inflammatory phenotype in human whole blood, confirming their cellular target engagement. Excellent broad selectivity, developability, and in vivo oral pharmacokinetics characterize these tools, which we hope will be of broad utility to the field of epigenetics research.

Industrially, the main methods for producing nitriles are ammoxidation and hydrocyanation. 105-34-0, formula is C4H5NO2, Name is Methyl 2-cyanoacetate. Both routes are green in the sense that they do not generate stoichiometric amounts of salts. Application of C4H5NO2.

Schierle, Simone;Chaikuad, Apirat;Lillich, Felix F.;Ni, Xiaomin;Woltersdorf, Stefano;Schallmayer, Espen;Renelt, Beatrice;Ronchetti, Riccardo;Knapp, Stefan;Proschak, Ewgenij;Merk, Daniel research published 《 Oxaprozin Analogues as Selective RXR Agonists with Superior Properties and Pharmacokinetics》, the research content is summarized as follows. The retinoid X receptors (RXR) are ligand-activated transcription factors involved in multiple regulatory networks as universal heterodimer partners for nuclear receptors. Despite their high therapeutic potential in many pathologies, targeting of RXR has only been exploited in cancer treatment as the currently available RXR agonists suffer from exceptional lipophilicity, poor pharmacokinetics (PK), and adverse effects. Aiming to overcome the limitations and to provide improved RXR ligands, we developed a new potent RXR ligand chemotype based on the nonsteroidal anti-inflammatory drug oxaprozin. Systematic structure-activity relationship anal. enabled structural optimization toward low nanomolar potency similar to the well-established rexinoids. Cocrystal structures of the most active derivatives demonstrated orthosteric binding, and in vivo profiling revealed superior PK properties compared to current RXR agonists. The optimized compounds were highly selective for RXR activation and induced RXR-regulated gene expression in native cellular and in vivo settings suggesting them as excellent chem. tools to further explore the therapeutic potential of RXR.

P. research published 《 Reactivity of trifluoromethyl-tetrazolo[1,5-a]pyrimidines in click chemistry and hydrogenation》, the research content is summarized as follows. The synthetic potential of tetrazolo[1,5-a]pyrimidines to obtain new pyrimidine derivatives via click chem. and hydrogenation was reported. Click chem. reactions of trifluoromethyl-tetrazolo[1,5-a]pyrimidines with terminal acetylenes produced unprecedented trifluoromethylated triazolylpyrimidines at excellent yields (84-98%), and one of them was active against all tested microorganisms, with moderate min. inhibitory concentration values (62.5-15.62μg/mL). Hydrogenation was performed using Pd/C-H₂ in MeOH under conventional, photochem., and pressure (5 bar) conditions. Hydrogenation was an excellent method for obtaining 2-amino-6-aryl-4-trifluoromethylpyrimidines and/or 2-amino-6-aryl-4-trifluoromethyltetrahydropyrimidines with a preference for 2-aminopyrimidine formation. Photochem. hydrogenation was the only pathway for reducing aryl-brominated substrates without dehalogenation. The reduction of trifluoromethyl-substituted tetrazolo[1,5-a]pyrimidines furnished 2-amino-6-aryl-4-trifluoromethylpyrimidines instead of the corresponding tetrahydropyrimidines. However, the hydrogenation of non-trifluoromethylated tetrazolo[1,5-a]pyrimidines showed a preference for tetrahydropyrimidine formation.

Saska, Jan;Shevchenko, Nikolay E.;Gonel, Goktug;Bedolla-Valdez, Zaira I.;Talbot, Rachel M.;Moule, Adam J.;Mascal, Mark research published 《 Synthesis and characterization of solution processable, high electron affinity molecular dopants》, the research content is summarized as follows. p-Type mol. dopants are a class of high electron affinity (EA) mols. used to ionize organic electronic materials for device applications. It is extremely challenging to ionize high-performance, high-ionization energy (IE) polymers because the dopant mol. needs to be compatible with solution processing. Here, we describe the synthesis and characterization of two new solution processable mol. dopants with the highest EA values yet reported. These mols., based on the parent hexacyanotrimethylenecyclopropane (CN6-CP) structure, achieve solubility by the substitution of one or more of the cyano groups with esters, which both reduces the volatility relative to CN6-CP and allows for solution processing. The efficacy of these new mol. dopants, which have EA values up to 5.75 eV with respect to vacuum, was tested by performing sequential solution doping experiments with a series of thiophene and alternating diketopyrrolopyrrole polymers with IEs ranging from 5.10 eV to 5.63 eV. For completeness, the new dopant results are compared to a previously reported tri-ester substituted CN6-CP analog with an EA of 5.50 EV. The increased EA of these stronger dopants induces a 10-100 fold increase in film conductivity and saturation of the conductivity at 15-100 S cm^-1 for almost all polymers tested. These new dopant structures enable controlled solution doping at high doping levels for most alternating co-polymers of interest to the organic electronics community.
