Since poly-gamma-glutamic acid (gamma-PGA) has been known as a potential biosorbent for removal of heavy metals from aqueous solutions, mucilage extracted from wasted natto (fermented soybeans) composed mainly of poly-glutamic acid and fructan can be expected as a low-cost gamma-PGA based biosorbent. The removal capacity of natto mucilage for biosorption of toxic heavy or rare-earth metal Nd chosen as a model heavy metal from aqueous solutions was studied. The Nd removal efficiency with the natto mucilage dosage of 500 mg L-1 was found to be comparable to that with the reagent-grade gamma-PGA dosage of 100 mg L-1. Although the maximum biosorption capacity of 51.3 mg-Nd(g-natto mucilage)(-1) is around a quarter of that for reagent-grade PGA or calcium alginate-poly glutamic acid hybrid gels reported in the literature, the estimated cost of the natto mucilage extracted from wasted natto using ethanol is less than one-tenth of the cost of the reagent-grade PGA. The spectra of FT-IR and XPS confirmed that the adsorption of Nd onto natto mucilage took place by electrostatic interaction with carboxylate anions and the Nd binding with amide and carboxylate anion groups of gamma-PGA and functional groups on the surface of fructan also contributed to removal of Nd by natto mucilage. The present results confirmed that natto mucilage is a promising low-cost poly-gamma-glutamic acid based biosorbent for removal of heavy metals from aqueous solutions.

Application of 138-41-0, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 138-41-0 is helpful to your research.

Hunting small molecules as anti-inflammatory agents/drugs is an expanding and successful approach to treat several inflammatory diseases such as cancer, asthma, arthritis, and psoriasis. Besides other methods, inflammatory diseases can be treated by lipoxygenase inhibitors, which have a profound influence on the development and progression of inflammation. In the present study, a series of new N-alkyl/aralky/aryl derivatives (7a-o) of 2-(4-phenyl-5-(1-phenylcarbamoyl)piperidine-4H-1,2,4-triazol-3-ylthio)acetamide was synthesized and screened for their inhibitory potential against the enzyme 15-lipoxygenase. The simple precursor ethyl piperidine-4-carboxylate (a) was successively converted into phenylcarbamoyl derivative (1), hydrazide (2), semicarbazide (3) and N-phenylated 5-(1-phenylcarbamoyl)piperidine-1,2,4-triazole (4), then in combination with electrophiles (6a-o) through further multistep synthesis, final products (7a-o) were generated. All the synthesized compounds were characterized by FTIR, H-1, C-13 NMR spectroscopy, EIMS, and HREIMS spectrometry. Almost all the synthesized compounds showed excellent inhibitory potential against the tested enzyme. Compounds 7c, 7f, 7d, and 7g displayed potent inhibitory potential (IC50 9.25 +/- 0.26 to 21.82 +/- 0.35 mu M), followed by the compounds 7n, 7h, 7e, 7a, 7b, 7l, and 7o with IC50 values in the range of 24.56 +/- 0.45 to 46.91 +/- 0.57 mu M. Compounds 7c, 7f, 7d exhibited 71.5 to 83.5% cellular viability by MTT assay compared with standard curcumin (76.9%) when assayed at 0.125 mM concentration. In silico ADME studies supported the drug-likeness of most of the molecules. In vitro inhibition studies were substantiated by molecular docking wherein the phenyl group attached to the triazole ring was making a pi-delta interaction with Leu607. This work reveals the possibility of a synthetic approach of compounds in relation to lipoxygenase inhibition as potential lead compounds in drug discovery.

The potential role of nine thiols as chemical protectors against the toxicity of paracetamol (acetaminophen, APAP) and its meta analogue N-acetyl-m-aminophenol (AMAP) was investigated using the density functional theory. They are glutathione (GSH), N-acetylcysteine (NAC), NAC amide (NACA), tiopronine (TPR), dihydrolipoic acid (DHL), 6-mercaptopurine (6MP), 6-thioguanine (6TG), 2,3-dimercaprol (DMC), and D-penicillamine (PNA). The investigation was focused on the toxic effects derived from protein arylation at cysteine residues, induced by the quinone imines formed from APAP and AMAP. On the basis of both thermochemical and kinetic considerations, with the exceptions of 6MP and 6TG, the investigated thiols may be useful in protecting the chemical integrity of cysteine residues in proteins from arylation by quinone imines. The order of efficiency for that purpose is predicted to be NAC > GSH > TPR > NACA > DMC > DHL. However, considering physicochemical properties that may affect bioavailability and cell permeability, DHL seems to be the best prospect to be orally supplied.

The first synthesis of isoxazole-4-carboxylic acid derivatives by domino isoxazole-isoxazole isomerization is reported. Fe(II)-catalyzed isomerization of 4-acyl-5-methoxy-/5-aminoisoxazoles (dioxane, 105 degrees C) leads to the formation of isoxazole-4-carboxylic esters and amides in good yields. 4-Formyl-5-methoxyisoxazoles give methyl oxazole-4-carboxylates under the same reaction conditions. Fe(II)-catalyzed isomerization of 4-acyl-5-methoxyisoxazoles under milder conditions (MeCN, 50 degrees C) allows the preparation of transient 2-acyl-2-(methoxycarbonyl)-2H-azirines. The azirines isomerize quantitatively either into isoxazoles under catalytic conditions (dioxane, 105 degrees C) or into oxazoles under noncatalytic thermolysis (o-dichlorobenzene, 170 degrees C). The mechanism of the isomerization and dependence of the reaction routes on substituents at starting isoxazole core and reaction conditions are discussed on the basis of DFT calculations.

The objective of this study was to establish and validate an UHPLC-MS/MS method for simultaneous determination of advanced glycation endproducts (AGEs) in either free or bound form in milk powder. The target analytes in free form in milk powder were extracted by 1% trichloroacetic acid, while target analytes in bound form were hydrolyzed by hydrochloric acid to cleave the protein amide bond and consequently dissociated. After extraction and purification, N-epsilon-(carboxymethyl)lysine (CML) and N-epsilon-(1-carboxyethyl)lysine (CEL) were quantified by internal standard method and pyrraline (Pyr) was by external standard method. Results revealed that three target analytes displayed excellent linearity in their corresponding concentration ranges. Limits of quantifications (LOQs) were in the range of 20-95 mu g/kg. The average recoveries of three target analytes spiked at three concentration levels were in the ranges of 81.8-107.2% with relative standard deviations (RSDs) of 3.5-8.1%. Finally, the described method was proved to be suitable for the quantification of these AGEs in milk powder products.

Four new amide derivatives, designated as cordycepiamides A-D (1-4), together with 14 known compounds (5-18), were isolated from the EtOAc-soluble fraction of the 95% EtOH extract of long-grain rice fermented with the endophytic fungus C. ninchukispora BCRC 31900, derived from the seeds of medicinal plant Beilschmiedia erythrophloia Hayata. Their structures were elucidated by means of spectroscopic and mass-spectrometric analyses, particularly 1D and 2D NMR spectroscopy as well as HRESIMS. All known isolates except 11, were isolated for the first time from this species. The antiinflammatory activities of selected isolated 10 compounds (1, 2, 4-6, 9-12, and 14) were evaluated as inhibitory activities against lipopolysaccharide (LPS) induced nitric oxide (NO) production in RAW264.7 cell lines. Compound 3 -> 4 was shown to have modest anti-inflammatory effects through inhibition of NO production in LPS-stimulated RAW264.7 cells.

The coordination chemistry of PdmBOX [2,5-bis(2-oxazolinyldimethylmethyl)pyrrole] pincer ligands, in which a dimethylmethylidene linker has been introduced to preclude rearrangements in the backbone, has been studied with 3d and 4d late transition metals. The in situ lithiated PdmBOX ligand was treated with MnCl2, FeCl2 and CoCl2 to give [(iPr)(PdmBOX)MCl] (M = Mn: 2; Fe: 3; Co: 4) which were found to adopt a distorted tetrahedral coordination geometry in the crystal. Addition of 2,6-dimethylphenylisocyanide to 3 gave the diamagnetic tris(isocyanide) derivative [(iPr)(PdmBOX)Fe(CNxyl)(3)]Cl (5) with the chloride as the counteranion. Complexes 2-4 were found to be precatalysts for the enantioselective hydrosilylation and hydroboration of acetophenone. The synthesis of PdmBOX-palladium(II) complexes was achieved by deprotonation of the protioligand with potassium bis(trimethylsilyl)amide (KHMDS) and subsequent reaction with [(cod)PdCl2] giving [(iPr)(PdmBOX)PdCl] (6) or by stirring (S)-(iPr)(PdmBOX)H with palladium acetate yielding the palladium acetato complex 7. Treatment of the latter with phenylsilane at 60 degrees C also led to the slow formation of the metal hydride complex which was the key species in the catalytic hydrosilylation of styrene oxide, albeit with low activity. The coordination of (S)-(iPr)(PdmBOX)H to rhodium(I) was accomplished by reaction with (acetylacetonato)dicarbonylrhodium(I) to give the corresponding PdmBOX-Rh complex 8 which reacted with methyl iodide to give the octahedrally coordinated rhodium(III) complex [(iPr)(PdmBOX)Rh(CH3)I(CO)] 9. Reaction of 8 with one equivalent of CsBr3 led to the full conversion to the dibromorhodium(III) complex [(iPr)(PdmBOX)Rh(CO)Br-2] 10. Upon reaction of 10 with N-bromosuccinimide (NBS), the pyrrole backbone in 10 was brominated to give complex 11. In a similar way, a selective conversion of [(iPr)(PdmBOX)NiCl] to the backbone-chlorinated [(iPr)((Cl)PdmBOX)NiCl] (12) was achieved by the treatment with N-chlorosuccinimide.

The apparent molar volumes of tetramethylurea (TMU) in the mixture of N,N-dimethylformamide (DMF) and water (W) have been determined within the temperature range: T = (293.15-308.15) K from density measurements. Based on Redlich-Meyer equation partial molar volumes and by coefficient describing the character of interactions were calculated. The results obtained for TMU showing hydrophobic properties have been compared with the corresponding results for urea that shows hydrophilic properties. This allowed us to analyze the solvation process of the investigated substances as well as to show an opposite behavior of urea in relation to TMU in the mixture DMF+W, particularly in the area of high water content.

Metabolites of methionine cycle, urea cycle and polyamine metabolism play important roles in regulating the metabolic processes and the development of diseases. It is rewarding and interesting to monitor the levels of the above metabolites in biological matrices to investigate pathological mechanisms. However, their quantitation is still unsatisfactory due to the poor retention behavior of the analytes on the traditional reversed-phase column. And never a single analytical method simultaneously quantify these three classes of metabolites. Besides, the concentrations of some metabolites are too low to be detected in the biological samples. In this study, we developed a UHPLC-ESI-MS/MS method to simultaneously determine the levels of 14 metabolites, including 4 methionine metabolism metabolites (methionine, homocysteine, S-adenosylmethionine and S-adenosylhomocysteine), 3 urea cycle intermediates (arginine, citrulline and ornithine) and 7 polyamines (putrescine, spermidine, spermine, N-1-acetylputrescine, N-1-acetylspermidine, N-1-acetylspermine and N-1,N-12-diacetylspermine). The chromatographic separation was performed on the BEH amide column within 14 min using water and acetonitrile (both with 0.1% formic acid) as the mobile phases. The results of method validation showed good selectivity, linearity (r(2) > 0.99), recovery (93.1%-112.1%), inter-day and intra-day precision (RSD < 13.6% and RSD < 11.0%, respectively), stability (RSD < 15.1%) and matrix effect (76.0%-113.2%). The method is simple, quick and sensitive without derivatization processes and the use of ion-pairing reagents. This approach was successfully applied in urine, serum and tissue matrices, as well as in identifying potential biomarkers for hyperthyroidism and hypothyroidism. The method is promising to provide more information on pathophysiological mechanisms in metabolomics study.
