The organocatalytic cyclization of propargylic amines/amides with carbonyl sulfide (COS) was firstly achieved by employing COS adducts of Lewis base (LB) as organocatalysts, affording various functionalized 1,3-thiazolidine-2-ones, and 1,3-thiazolidine-2,4-diones derivatives in a highly chemo- and stereoselective manner. The isotope labeling and stoichiometric experiments suggested the LB-COS adducts preferentially mediated basic ionic pair mechanism. Furthermore, the practical application of this methodology was highlighted by the highly efficient synthesis of rosiglitazone using COS as sulfur source.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 13734-41-3, in my other articles.

An easy-to-make supramolecular polymer was successfully constructed by self-assembly of tripodal tri-(pyridine-4-yl)-functionalized trimesic amide (DTB) in DMSO-H2O binary solutions. The supramolecular polymer DTB showed strong white aggregation-induced emission (AIE) in the solid state as well as in water suspensions. DTB could also form a stable supramolecular polymer hydrogel (DTB-G) in pure water. Interestingly, DTB showed excellent coordination ability for rare earth metal ions (Tb3+, Eu3+, La3+, Th4+ and Ce3+) and formed the corresponding complexes (DTB-Ms). Interestingly, by introducing the above-mentioned rare earth metal ions, the fluorescence colour of the obtained DTB-Ms showed corresponding variations. By inseting UV-LED lamps ( = 365 nm) into different rare earth metal ion-coordinated xerogel DTB-Ms in small test tubes, a series of LED devices with multicolour lights were obtained. Therefore, DTB and DTB-Ms can act as fluorescence colour-tunable photoluminescence materials.

Derivatives of the new ring system benzo[f]pyrimido[1,2-d][1,2,3]triazolo[1,5-a][1,4]diazepinone and its cycloalkane and cycloalkene condensed analogues have been conveniently synthesized through a three-step reaction sequence. An atom-economical, one-pot, three-step cascade process engaging five reactive centers (amide, amine, carbonyl, azide, and alkyne) has been performed for the synthesis of alicyclic derivatives of quinazolinotriazolobenzodiazepine using cyclohexane, cyclohexene, and norbornene beta-amino amides. The stereochemistry and relative configurations of the synthesized compounds were determined by 1D and 2D NMR spectroscopy and X-ray crystallography. The reaction was also performed using enantiomeric starting materials leading to enantiomeric quinazolinotriazolobenzodiazepine with an ee of 95%. The synthesis of 9H-benzo[f]pyrimido[1,2-d][1,2,3]triazolo[1,5-a][1,4]diazepinone, a new heterocyclic system, was achieved in a good yield using a retro Diels-Alder (RDA) procedure.

We optimized our previously reported proline-based STAT3 inhibitors into an exciting new series of (R)-azetidine-2-carboxamide analogues that have sub-micromolar potencies. (5a) under bar, (5o) under bar, and (8i) under bar have STAT3-inhibitory potencies (IC50) of 0.55, 0.38, and 0.34 mu M, respectively, compared to potencies greater than 18 mu M against STAT1 or STATS activity. Further modifications derived analogues, including 7 (e) under bar, (7f) under bar, (7g) under bar, and (9k) under bar, that addressed cell membrane permeability and other physicochemical issues. Isothermal titration calorimetry analysis confirmed high-affinity binding to STAT3, with K-D of 880 nM ((7g) under bar) and 960 nM ((9k) under bar). (7g) under bar and (9k) under bar inhibited constitutive STAT3 phosphorylation and DNA-binding activity in human breast cancer, MDA-MB-231 or MDA-MB-468 cells. Furthermore, treatment of breast cancer cells with (7e) under bar, 7 (f) under bar , (7g) under bar, or (9k) under bar inhibited viable cells, with an EC50 of 0.9-1.9 mu M, cell growth, and colony survival, and induced apoptosis while having relatively weaker effects on normal breast epithelial, MCF-10A or breast cancer, MCF-7 cells that do not harbor constitutively active STAT3.

The reduction of ketones by SmI2-water has long been thought to proceed through a reversible initial electron transfer with the formation of organosamarium intermediates in a follow-up step. Kinetic experiments on the reduction of two model ketones and structurally similar ketones with a pendant alkene are shown to be consistent with a rate-limiting reduction by SmI2-water through a proton-coupled electron-transfer (PCET). Literature values for the rates of radical cyclizations and reduction of radicals by SmI2 and thermochemical data for radical reduction by SmI2-water further support a rate-limiting initial step for ketone reductions. These data suggest that discrete organosamarium species may not be intermediates in ketone reductions by SmI2-water.

Halide anion free hydrophilic Deep Eutectic Solvent (DES) based on choline dihydrogen citrate and urea (1:2 mol ratio) was prepared and successfully employed for dissolution of uranium compounds. Dissolution study was carried out with oxides viz. UO2, UO3 and crude yellow cakes viz. magnesium diuranate, sodium diuranate. Novel route of in-situ, single step eutectic solvent preparation and U compound dissolution was found to be promising in terms of better dissolution efficiency and process simplification. The resultant systems were probed with electrochemistry and UV-Vis spectrophotometry to get an insight about the uranium species. In all the four systems prepared by in-situ mode, stabilization of uranium in U(VI) oxidation state in the form of oxo species was indicated. This halide anion free eutectic system was amenable to be used in SC CO2 extraction set-up. SC CO2 extraction of uranium dissolved in eutectic solvent was found to be influenced by various extraction conditions viz. pressure, temperature, static and dynamic time. Uranium extraction efficiency of upto 65% for oxide system was achievable by SC CO2 modified with TTA.

Biofilms cause a variety of pervasive problems in water treatment, distribution and reuse systems that are difficult to mitigate due to their resistance to disinfectants. We used magnetic phage-nanocomposite conjugates (PNCs) to target bacteria in biofilm inner layers for bottom-up eradication. Polyvalent Podoviridae phages PEB1 (54 nm) or PEB2 (86 nm) were covalently conjugated (via amide bonds) with magnetic colloidal nanoparticle clusters (CNCs) of different sizes (150, 250 or 500 nm). Smaller CNCs with higher density of amino groups loaded phages more efficiently than the largest CNCs (e.g., for PEB1, 60 +/- 4, 62 +/- 5, and 47 +/- 4 phages were loaded per mu m2). Smaller PNCs dispersed phages more evenly throughout the biofilm bottom, significantly disrupting the biofilm bottom layer and detaching the biofilm within 6 h. The biofilm removal efficiency was 98.3 +/- 1.4% for dual species biofilm (i.e., Escherichia coli and Pseudomonas aeruginosa) and 92.2 +/- 3.1% for multi-species biofilm (i.e., E. coli, P. aeruginosa, and non-hosts Bacillus subtilis and Shewanella oneidensis). Large PNCs caused higher physical disruption but lower corresponding removal efficiencies (i.e., 80.2 +/- 3.4% for dual species biofilm and 67.6 +/- 3.8% for multi-species biofilm) due to lower horizontal diffusion at the bottom of the biofilm. A semi-empirical numerical model corroborated the higher biofilm removal efficiency with smaller PNCs and inferred that PNC size influences the mode of phage propagation: Small PNCs facilitate biofilm bottom clearance with significant horizontal dispersion while large PNCs mainly enhance vertical propagation. Overall, this study demonstrates the importance of size control to enhance the biofilm eradication capability of PNCs as an alternative or complementary biofilm control strategy.

The first heterogeneous gold(I)-catalyzed direct C(sp(2))-C(sp) bond functionalization of arylalkynes through a nitrogenation process to amides has been achieved by using an ordered mesoporous silica (MCM-41)-immobilized phosphine gold(I) complex [MCM-41-PPh3-AuCl] as catalyst and silver carbonate (Ag2CO3) as cocatalyst with trimethylsilyl azide (TMSN3) as a nitrogen source, yielding a variety of amides in moderate to excellent yields under mild conditions. This heterogeneous phosphine gold(I) complex shows the same turnover numbers as the homogeneous chloro(triphenylphosphine)gold(I) (Ph3PAuCl) and can easily be recovered by simple filtration of the reaction solution and recycled at least eight times without significant loss of activity, providing a novel, efficient, practical and economic method for the synthesis of amides from alkynes.

The development of amino acid surfactants which are considered to be biodegradable and less toxic than traditional surfactants has been a subject of growing interests among chemists for the past 20 years. Within this category, N-acyl amino acid surfactants are popular due to their excellent interfacial properties and antimicrobial activities. In the present work, six new N-acyl amino acid surfactants were synthesized using vegetable oils (castor oil and cottonseed oil) and amino acids (glycine, alanine, and serine). Surface active properties of these surfactants were investigated. With the amide bonds acting as hydrogen bond donors and acceptors, globular and tubular vesicles were observed in the aqueous solutions of some prepared surfactants. The results indicated that hydroxyl groups on the hydrophobic tails for castor oil derivatives were associated with spherical vesicles formation, whereas serine residues bearing hydroxyl groups may be associated with the tubular vesicles.
