Urea-free reactive printing of viscose fabric with high color performance for cleaner production

Urea-free reactive printing has gained popularity as part of cleaner production in the textile printing industry. Printing additives containing little to no nitrogen are being explored as substitutes for urea. In this study, the hygroscopicity, ability to swell fibers, and ability to solubilize reactive dyes of various additives were compared to explore the intrinsic connections between the structures and the above-mentioned properties. The hydrogen-bond interactions between the reactive dye and additives were characterized by H-1 NMR and DSC. Additives with good hygroscopic, swelling, and solubilizing properties were selected for their potential application in urea-free reactive deep printing on viscose fabric. Results showed that among various kinds of additives, glycerol had the best hygroscopicity, 1,4-butanediol had the best ability to swell viscose fibers, and the amides had the best ability to solubilize reactive turquoise K-GL. Hygroscopicity was considered as the most important factor, followed by the ability to swell fibers. When the mixed ratio of glycerol and 1,4-butanediol was 5:5, the color performances of the binary nitrogen-free compound were higher than those of a commercial alternative. Its printing performances came close to those of urea, exhibiting great potential as a substitute for urea. Nitrogen-free alternatives will remarkably reduce the ammonia-nitrogen pollutants emitted into the environment by the reactive printing process.

Organocatalyzed C-N bond-forming Reactions for the Synthesis of Amines and Amides

The synthesis of organonitrogen compounds via C-N bond formation emerges as a versatile route for drug discovery. Most of the pharmaceuticals and natural products, which are predominantly used generally contain amine functionalities and amide linkages in their structure. Traditionally, the synthesis is done by using several metal catalysts and hazardous chemicals. The organocatalyzed synthetic protocol provides a sustainable and eco-compatible route for the synthesis of organonitrogen compounds and at the same time also avoids metal contamination. The main aim of this Review is to provide an overview of the organocatalyzed amine and amide synthesis via C-N bond formation reactions. We hope this Review provides valuable information about the organocatalyzed reaction to enable the development of more sustainable routes to form these linkages.

N-Annulated perylene-based organic dyes sensitized graphitic carbon nitride to form an amide bond for efficient photocatalytic hydrogen production under visible-light irradiation

In this work, two new N-annulated perylene-based organic sensitizers (PY-1 and PY-2) have been developed for dye-sensitized graphitic carbon nitride (g-C3N4) to remarkably enhance photocatalytic hydrogen production under visible-light irradiation (420 nm <= lambda <= 780 nm). The results showed that the H-2 production rates of the PY-1/g-C3N4/Pt and PY-2/g-C3N4/Pt were up to 5508.1 mu mol h(-1) g(-1) and 11,855.4 mu mol h(-1) g(-1) respectively, which were 8.98 and 19.3 times higher than that of the g-C3N4/Pt, respectively. Specifically, an impressive record apparent quantum efficiency (AQY) of 27.16% for PY-2/g-C3N4/Pt system was achieved at lambda = 550 nm monochromatic light irradiation. Moreover, the formation of amide bonds between dye molecules and g-C3N4 was firstly confirmed by FTIR spectrum and theoretical calculation. The amide bonds provided the electron transfer channels to significantly improve interface charge transfer and separation, thus resulting in a more efficient hydrogen production. More importantly, PY-1/g-C3N4/Pt and PY-2/g-C3N4/Pt displayed good stability under long-term irradiation and was favorable and significant for practical application. Our work indicated that dye sensitized g-C3N4 to form an amide bond is a promising strategy to realize the effective conversion of solar energy to hydrogen energy through molecular engineering. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.

Induction of Caspase-Mediated Apoptosis in HepG2 Liver Carcinoma Cells Using Mutagen-Antioxidant Conjugated Self-Assembled Novel Carbazole Nanoparticles and In Silico Modeling Studies

In this study, novel self-assembled carbazole-thiooctanoic acid nanoparticles (CTNs) were synthesized from amino carbazole (a mutagen) and thiooctanoic acid (an antioxidant). The nanoparticles were characterized using hyperspectral techniques. Then, the antiproliferative potential of CTNs was determined in HepG2 liver carcinoma cells. This study employed a solvent-antisolvent interaction method to synthesize a spherical CTN of size less than 50 nm. Moreover, CT was subsequently capped to gold nanoparticles (AuNPs) in the additional comparative studies. The CT derivative was synthesized from carbazole and lipoic acid by the amide bond formation reaction using a coupling agent. Furthermore, it was characterized using infrared (IR), H-1 nuclear magnetic resonance, dynamic light scattering (DLS), and transmission electron microscopy techniques. The CT-capped gold nanoparticles (CTAuNPs) were prepared from CT, chloroauric acid, and NaBH4. The CTAuNPs were characterized using ultraviolet-visible, high-resolution TEM, DLS, and Fourier transform IR techniques. The cytotoxicity and apoptosis-inducing ability of both nanoparticles were determined in HepG2 cells. The results demonstrate that CTNs exhibit antiproliferative activity in the cancerous HepG2 cells. Moreover, molecular docking and molecular dynamics studies were conducted to explore the therapeutic potential of CT against human EGFR suppressor protein to gain more insights into the binding mode of the CT, which may show a significant role in anticancer therapy.

Topological control of supramolecular crystal structures of phenylene bis-monothiooxamate derivatives and in vitro anticancer activity

This paper describes the synthesis, physical characterization, X-ray crystal structures and antitumoral activity against human carcionogenic cells of three new diethyl ester acid derivatives of phenylene bismonothiooxamate compounds, namely Et2H2opbta (1), Et(2)H(2)mpbta (2) and Et(2)H(2)ppbta (3) [opbta = N,N’-1,2-phenylenebis(2-thiooxamate), mbpta = N,N’-1,3-phenylenebis(2-thiooxamate) and ppbta = N,N’-1,4-phenylenebis(2-thiooxamate)]. Compounds 1-3 were obtained under mild conditions by reaction of the corresponding N,N’-phenylenebis(oxamate) analogues and Lawesson’s reagent resulting in the formation of C=S bonds at the carbonyl amide functions. Crystal structures of 1-3 consist of 1D supramolecular assemblies of centrosymmetric H2Et2ppbta (3) or noncentrosymmetric chiral H(2)Et(2)opbta (1) and H(2)Et(2)mpbta (2) molecules with opposite helical chirality (M and P enantiomers) resulting from intermolecular N H center dot center dot center dot O (1 and 3) or N H center dot center dot center dot S (2) hydrogen bonds between the amide hydrogen atoms and the carbonyl ester oxygen or thionyl amide sulfur atoms from the thiooxamate moieties respectively, together with weak S center dot center dot center dot S bonds between the thionyl amide sulfur atoms (1). The cytotoxicity of H(2)Et(2)xpbta [x = o (1), m (2) and p (3)] against chronic myelogenous leukemia cells was evaluated and the bioactivity follows the order 1 >> 2 > 3, compound 1 being six and ten times more active than 2 and 3, respectively.

The Ritter Reaction of 2-Oxoaldehydes at Room Temperature: Divergent Behaviour towards Acid Strength

An efficient, novel, atom economical and selective amidation method for the generation of mono and di-Ritter products using 2-oxoaldehydes under acidic environment at room temperature was successfully developed. The di-Ritter products obtained are accessed in good yields when stirred in the presence of 20 mol % H2SO4, and the mono products were selectively obtained in moderate yields with CuOTf as catalyst. However, the yields of the latter were optimized by the addition of SeO2.

Binge Alcohol Exposure Transiently Changes the Endocannabinoid System: A Potential Target to Prevent Alcohol-Induced Neurodegeneration

Excessive alcohol consumption leads to neurodegeneration, which contributes to cognitive decline that is associated with alcohol use disorders (AUDs). The endocannabinoid system has been implicated in the development of AUDs, but little is known about how the neurotoxic effects of alcohol impact the endocannabinoid system. Therefore, the current study investigated the effects of neurotoxic, binge-like alcohol exposure on components of the endocannabinoid system and related N-acylethanolamines (NAEs), and then evaluated the efficacy of fatty acid amide hydrolase (FAAH) inhibition on attenuating alcohol-induced neurodegeneration. Male rats were administered alcohol according to a binge model, which resulted in a transient decrease in [H-3]-CP-55,940 binding in the entorhinal cortex and hippocampus following two days, but not four days, of treatment. Furthermore, binge alcohol treatment did not change the tissue content of the three NAEs quantified, including the endocannabinoid and anandamide. In a separate study, the FAAH inhibitor, URB597 was administered to rats during alcohol treatment and neuroprotection was assessed by FluoroJade B (FJB) staining. The administration of URB597 during binge treatment did not significantly reduce FJB+ cells in the entorhinal cortex or hippocampus, however, a follow up target engagement study found that NAE augmentation by URB597 was impaired in alcohol intoxicated rats. Thus, potential alcohol induced alterations in URB597 pharmacodynamics may have contributed to the lack of neuroprotection by FAAH inhibition.

Design, synthesis and biological evaluation of N-(3-(1H-tetrazol-1-yl)phenyl)isonicotinamide derivatives as novel xanthine oxidase inhibitors

In our previous study, we reported a series of N-phenylisonicotinamide derivatives as novel xanthine oxidase (XO) inhibitors and identified N-(3-cyano-4-((2-cyanobenzyl)oxy)phenyl)isonicotinamide (compound 1) as the most potent one with an IC50 value of 0.312 mu M. To further optimize the structure and improve the potency, a structure-based drug design (SBDD) strategy was performed to construct the missing H-bond between the small molecule and the Asn768 residue of XO. We introduced a tetrazole moiety at the 3′-position of the phenyl to serve as an H-bond acceptor and obtained a series of N-(3-(1H-tetrazol-1-yl)phenyl)isonicotinamide derivatives (2a-t and 6-8). Besides, to investigate the influence of the amide-reversal, some N-(pyridin-4-yl)-3-(1H-tetrazol-1-yl)benzamide derivatives (3c, 3e, 3l, 3k and 3u) were also synthesized and evaluated. Biological evaluation and structure-activity relationship analysis demonstrated that the 3′-(1H-tetrazol-1-yl) moiety was an excellent fragment for the N-phenylisonicotinamide scaffold; a substituted benzyloxy, especially, an m-cyanobenzyloxy (e.g., 2s), linking at the 4′-position was welcome for the potency; and the amide-reversal could damage the potency, so maintenance of the N-phenylisonicotinamide scaffold was essential. In summary, starting from compound 1, the SBDD effort successfully identified a promising XO inhibitor 2s (IC50 = 0.031 mu M), with a 10-fold gain in potency. Its potency was very close to the positive control topiroxostat (IC50 = 0.021 mu M). A Lineweaver-Burk plot indicated that compound 2s acted as a mixed-type XO inhibitor. Molecular docking and molecular dynamics simulations revealed that the tetrazole moiety could occupy the Asn768-sub-pocket with N-4 atom accepting an H-bond from the Asn768 residue, as expected.

Synthesis of Tetra-Substituted Trifluoromethyl-3,1-Benzoxazines by Transition-Metal-Catalyzed Decarboxylative Cyclization of N-Benzoyl Benzoxazinones

Efficient synthesis of N,O-heterocyclic tetra-substituted trifluoromethyl-3,1-benzoxazines via a transition-metal-catalyzed decarboxylative intramolecular cyclization was achieved. The decarboxylation of N-benzoyl trifluoromethyl-benzoxazinones generated the amide oxygen nucleophile, allowing a selective internal C-1-attack on Pd- or Cu-coordinated zwitterions, affording medicinally attractive tetra-substituted vinyl- or ethynyl-trifluoromethyl-3,1-benzoxazines. This protocol can be applied to the synthesis of perfluoroalkyl- and non-fluorinated 3,1-benzoxazines.
