Biocalcium powder from precooked skipjack tuna bone: Production and its characteristics

Biocalcium (BC) powder from the bones of precooked skipjack tuna was produced and characterized, compared to calcined bone (CB) powder. Higher calcium (40.35%) and phosphorous (15.28%) contents were found in the CB powder, compared to BC powder (26.91 and 12.63%, respectively). Nevertheless, similar Ca/P ratio was observed (1.62-1.65). Mean particle sizes of both powders were 17.07-20.29 mu m. BC powder had higher b* (yellowness) with slightly lower L* (lightness) values than the CB counterpart (p<.05). Both samples showed a characteristic peak of hydroxyapatite in X-ray diffraction patterns, in which the crystallinities of the BC and CB powders were 45.19 and 74.69%, respectively. Amides I, II, and III peaks in Fourier transform infrared spectrum, hydroxyproline, and protein were detected only in the BC powder. BC powder had a low abundance of volatile compounds, including aldehydes, alcohols, and ketones. A negligible amount of volatiles was found in the CB powder. Practical applicationsCalcium supplementation has been increasingly used to alleviate the lack of calcium in the human body, particularly inadequate levels of calcium and poor absorption. Calcium associated with peptides or biocalcium (BC) has a higher advantage in terms of absorption than calcium alone. Precooked skipjack tuna is considered a promising source for BC production due to its abundance. BC with improved color and odor along with increased solubility in gastrointestinal tract can be used as an alternative calcium supplement to tackle the inadequate intake of dietary calcium. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Near-Infrared Fluorescent Probe with Remarkable Large Stokes Shift and Favorable Water Solubility for Real-Time Tracking Leucine Aminopeptidase in Living Cells and In Vivo

Leucine aminopeptidase (LAP) is a kind of proteolytic enzymes and associated closely with pathogenesis of cancer and liver injury. Accurate detection of LAP activity with high sensitivity and selectivity is imperative to detect its distribution and dynamic changes for understanding LAP’s function and early diagnosing the disease states. However, fluorescent detection of LAP in living systems is challenging. To date, rarely fluorescent probes have been reported for imaging LAP in vivo. In this study, a novel probe (TMN-Leu) was developed by conjugating a near-infrared dicyanoisophorone derivative fluorophore with LAP activatable L-leucine amide moiety for the first time. TMN-Leu featured large Stokes shift (198 nm), favorable water solubility, ultrasensitive sensitivity (detection limit of similar to 0.38 ng/mL), good specificity, excellent cell membrane permeability, low toxicity, and a prominent near-infrared emission (658 nm) in response to LAP. TMN-Leu has been successfully applied to track LAP of cancer cells and normal cells, monitor LAP changes in different disease models, and rapidly evaluate LAP inhibitor in cell-based assay. Notably, this probe firstly revealed that HCT116 cells with higher LAP activity were more invasive than LAP siRNA transfected HCT116 cells, suggesting that LAP might serve as an indicator reflecting the intrinsic invasion ability of cancer cells. Finally, TMN-Leu was also employed for in vivo real-time imaging LAP in living tumor-bearing nude mice with low background interference. All together, our probe possesses potential value as a promising tool for diagnostic application, cell-based screening inhibitors and in vivo real-time tracking enzymatic activity in preclinical applications.

Successive Protonation of an N-Heterocyclic Imine Derived Carbonyl: Superelectrophilic Dication Versus Masked Acylium Ion

Carbonyl cations are among the most commonly invoked reactive intermediates in organic synthesis. While Olah pioneered superacids to provide a stable ion environment for their study in situ, isolated examples are rare. Here, we disclose successive protonation of an N-heterocyclic imine (NHI) derived carbonyl compound (IDippN)(2)CO, 2, to the monocation [(IDippN)(IDippNH) CO](+), [3](+), and the doubly protonated dication [(IDippNH)(2)CO](2+), [4](2+). [3](+) represents a rare example of an N-protonated carbonyl cation and [4](2+) the first example of a superelectrophilic carbonyl dication. All three compounds have been characterized by X-ray crystallography and IR spectroscopy, revealing stepwise strengthening of the C=O bond on protonation. The unique stability of these systems is attributed to the enhanced basicity and steric profile provided by the NHI substituents. In addition, we report the related singly NHI-stabilized cation [IDippNCO](+), [5](+). Crystallographic and DFT analyses provide insight into the interaction between the carbonyl fragment and the NHI, which reveals that the [CNCO](+) unit (isoelectronic to CCCO) can be described as an acylium cation masked as a cumulene.

Estradiol Removal by Adsorptive Coating of a Microfiltration Membrane

This work demonstrates the enhancement of the adsorption properties of polyethersulfone (PES) microfiltration membranes for 17 beta-estradiol (E2) from water. This compound represents a highly potent endocrine-disrupting chemical (EDC). The PES membranes were modified with a hydrophilic coating functionalized by amide groups. The modification was performed by the interfacial reaction between hexamethylenediamine (HMD) or piperazine (PIP) as the amine monomer and trimesoyl chloride (TMC) or adipoyl chloride (ADC) as the acid monomer on the surface of the membrane using electron beam irradiation. The modified membranes and the untreated PES membrane were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), water permeance measurements, water contact angle measurements, and adsorption experiments. Furthermore, the effects of simultaneous changes in four modification parameters: amine monomer types (HMD or PIP), acid monomer types (TMC or ADC), irradiation dosage (150 or 200 kGy), and the addition of toluene as a swelling agent, on the E2 adsorption capacity were investigated. The results showed that the adsorption capacities of modified PES membranes toward E2 are >60%, while the unmodified PES membrane had an adsorption capacity up to 30% for E2 under similar experimental conditions, i.e., an enhancement of a factor of 2. Next to the superior adsorption properties, the modified PES membranes maintain high water permeability and no pore blockage was observed. The highlighted results pave the way to develop efficient low-cost, stable, and high-performance adsorber membranes.

Modifier-free separation of trivalent actinides and lanthanides from fast reactor simulated high-level liquid waste using N,N-di-octyl-2-hydroxyacetamide

The extraction behaviour of Am(III) and other metal ions present in the fast reactor simulated high- level liquid waste (FR-SHLLW) was studied using a modifier-free solvent phase composed of N,N-di-octyl-2-hydroxyacetamide (DOHyA) in n-dodecane. Quantitative extraction of Am(III) was achieved with the co-extraction of all lanthanides, Y(III) and Mo(VI) in the first five stages of a 20-stage mixer-settler. During the stripping run with 0.5 M HNO3, Am(III), Ln(III) and Y(III) were quantitatively transferred to the aqueous product in three stages. The other extracted metal ions were retained in organic phase. The results showed that the extraction performance of DOHyA was superior to other amide extractant systems reported in the literature.

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.
