Background Palmitoylethanolamide (PEA) is an endogenous fatty acid amide that has shown anti-inflammatory activity and neuroprotection and has been used for the treatment of compressive syndromes. The aim of this study is to investigate the clinical and electrophysiological effects of conservative treatment with PEA in low to moderate carpal tunnel syndrome (CTS). Materials and methods A prospective double-blinded randomized study was performed on 61 patients with a clinical and electrophysiologically confirmed diagnosis of low and moderate CTS. The patients were randomly assigned to two groups. Group N was given 300 mg of PEA twice a day over 60 days and Group P received a placebo with exactly the same appearance every 12 h for the same period. CTS was evaluated before and after treatment through clinical findings, Boston Carpal Tunnel Questionnaire, visual analog scale (VAS) and electrophysiological data. The results were evaluated with Student’s t test and chi-squared test. Results No differences were observed in either group compared to the initial status regarding Durkan’s test, Phalen’s test, VAS and electrophysiological data after treatment. The Boston Questionnaire showed better results in both groups, with an improvement in only the symptom severity scale (SSS; p = 0.002809) for group P and improvement in the functional status scale (FSS; p = 0.03334) and SSS (p = 0.005) for group N. Conclusions The results of this study suggest that treatment of CTS with PEA at a dose of 600 mg/day is not associated with an improvement of any clinical and electrophysiological parameters. However, we observed an improvement in the FSS in the Boston Questionnaire after treatment with PEA. Together with the results of other studies, we conclude that further studies of PEA in CTS at higher doses are necessary.

Spilanthol is the most abundant pharmacologic agent present in Acmella oleracea, a popular Amazonian plant usually called as Jambu. We performed an experimental and theoretical investigation on several electronic properties connected to the molecular structure of spilanthol (S1) and the other two analogs (S2 and S3). Our FT-IR analysis is not conclusive but suggests the existence of a resonance structure that oscillates between the NH = C – O to the NH – C = O conformations involving the amide nitrogen and carbon atom of the carbonyl group. We confirmed this proposal for all alkylamides by using appropriate DFT/6-311++G(d,p) level of theory and confirmed that the NH = C – O enters with greater width. Our analysis also shows that the UV-vis spectra are strongly affected by the number of C = C bonds, and suffer an uncommon blue shift from S1 to the S3 structure. Our nonlinear optical (NLO) investigation based on DFT methods shows that the chromophores could have some use in optoelectronic due to they present second-hyperpolarizability of similar to 72 x 10(-36) esu, in competition with urea, PNA, and some chalcones. The analysis of the global reactive descriptors shows that spilanthol and its two analogs are classified as strong electrophilic chromophores with omega > 1.5 eV. However, the systematic inclusion of the C C bonds from S1 to S3 turns the system less nucleophile. While spilanthol is a strong nucleophile with N > 3.0 eV, the remaining S2 and S3 chromophores can be classified as moderate nucleophilic systems with 2.0 <= N <= 3.0 eV. These results suggest that S2 and S3 molecules have great potential as pharmacological agents. (C) 2020 Elsevier B.V. All rights reserved.

The asymmetric syntheses of the N-terminal alpha-hydroxy-beta-amino acid components of microginins 612, 646 and 680 are reported. Conjugate addition of lithium (R)-N-benzyl-N-(alpha-methylbenzyl)amide to the requisite (E)-alpha,beta-unsaturated ester followed by in situ enolate oxidation with (-)-(camphorsulfonyl)oxaziridne (CSO) gave the corresponding anti-alpha-hydroxy-beta-amino esters. Sequential Swern oxidation followed by diastereoselective reduction gave the corresponding syn-alpha-hydroxy-beta-amino esters. Subsequent N-debenzylation (i.e., hydrogenolysis for microginin 612, and NaBrO3-mediated oxidative N-debenzylation for microginins 646 and 680) followed by acid catalysed ester hydrolysis gave the corresponding syn-alpha-hydroxy-beta-amino acids, the N-terminal components of microginins 612, 646 and 680, in good yield. An analogous strategy for elaboration of the enantiopure anti-alpha-hydroxy-beta-amino esters facilitated the asymmetric synthesis of the corresponding C(2)-epimeric alpha-hydroxy-beta-amino acids.

The macronutrient potassium (K) has vital physiological functions in plants and its availability can strongly impact quality of crops like tomato. The impact of K nutrition on conventional tomato fruit quality parameters has been described several times, but detailed investigations on the effect of K supply on the fruit metabolite profile are still rare. To fill this gap, we investigated the influence of K fertilization on the metabolite profile of tomato fruits. For this purpose, an outdoor pot experiment with three different cocktail tomato cultivars was performed. A fertilization regimen with five K levels was applied, ranging from deficiency to sufficient supply. Fruit samples were analyzed by untargeted GC x GC-MS to cover the primary metabolite profile as well as some secondary metabolites. As verified using ICP-OES, fruit K content was highly proportional to the supplied amount of K. At the metabolite profile level, the most prominent and cultivar-independent effect of increased K fertilization was the rise of tricarboxylic acid (TCA) cycle intermediates. Further effects were more cultivar-specific, for example an increase of the mobile nitrogen pool (e.g. amines like putrescine and amides like asparagine), changes in the profile of minor sugars (especially disaccharides) as well as higher levels of some secondary metabolites. Pronounced response patterns were mainly observed in the cultivars Primavera and Yellow Submarine that were recently characterized as higher yielding, demanding a stronger consideration of cultivar differences in future studies.

A range of environmentally friendly solvents was evaluated in the Suzuki-Miyaura coupling of amides in an attempt to provide the first solvent selection guide for the powerful C-C coupling by amide bond cleavage. Of the 14 solvents and 10 Pd-NHC catalysts (NHC = N-heterocyclic carbene) considered, i-PrOAc was identified as the recommended, environmentally friendly solvent for the coupling. The obtained data permit an overall ranking of the recommended solvents in the Suzuki-Miyaura coupling of amides, with methyl t-butyl ether (MTBE), cyclopentyl methyl ether (CPME), diethyl carbonate (DEC), p-cymene, dimethylcarbonate (DMC), and anisole as alternative recommended solvents in terms of health, safety, and environmental ranking for the coupling. The data should facilitate the replacement of hazardous solvents with green organic solvents in the biorelevant manifold of amide bond coupling for the further implementation of amide bond activation methods.

Asymmetric Mannich-type addition of 3,5-disubstituted-4-nitroisoxazoles to isatin-derived Boc-protected imines has been realized by using 0.01 equiv of amide phosphonium salt as a phase transfer catalyst. Our current methodology allows for the formation of 3-isoxazolylmethyl-substituted 3-aminooxindoles in excellent yields with good to excellent enantioselectivities. The practical value of this methodology was exemplified by a gram-scale synthesis of 5an, a key intermediate for the formal synthesis (+)-AG-041R.

The benzimidazole-based derivatives 2a-c were designed and synthesized via C-N coupling reaction and experimentally characterized by infrared spectroscopy (FT-IR), nuclear magnetic resonance (H-1 NMR) spectroscopy and mass spectrometry (MS). The observed and calculated FT-IR frequencies correspond to C=O stretching of amide group are depicted at 1657, 1672 and 1682, 1689 and 1699, 1682 for 2a, 2b and 2c respectively and are in good agreement. The synthesized compounds 2a-c exhibit non-linear optical response with the first hyperpolarizability (beta(0)) at 783, 1550 and 694 au, respectively. Due to the presence of electron withdrawing -NO2 on the primary amine of 2b, the beta(0) value is estimated at 1550 au, which reduces the energy barrier hence increasing the beta(0) value, with maximum UV-vis absorption at 224 nm with TD-DFT method. The opposite behavior is demonstrated by the electron donor -OCH3 substituent. This study of NLO responses would be beneficial to the development of high-performance NLO materials.

Scarce knowledge on the behavior of vitamins in aqueous solutions in the presence of additives is often a limiting factor for industrial applications such as process design and optimization. Knowing the pH-solubility profiles of vitamins is fundamental for understanding and controlling their behavior in aqueous solutions. In the present work, pH-dependent solubilities of the vitamins ascorbic acid (VC), riboflavin (VB2), nicotinic acid (VB3(acid)), folic acid (VB9), and cyanocobalamin (VB12) were measured at T = 298.15 K and p = 1 bar. These results were compared to the pH-solubility profiles obtained with modified Henderson-Hasselbalch equations using pK(a) values from the literature. Further, the solubilities of poorly soluble VB2, VB9, and VB12 were increased by the addition of covitamins VC, VB3(acid), and nicotinamide (VB3(acid)). As observed, VB3(amide )increases the vitamin solubility much stronger than VC and VB3(acid). These covitamins are called hydrotropes in several works in the literature, and they increase the solubility of other vitamins by manipulating the pH of the saturated solutions and by molecular cross-interactions. The interplay between both pH and cross-interactions depends strongly on the kind and concentration of covitamin. At low concentrations, VC and VB3(amide) (<0.2 m) increased solubility by pH change. At higher concentrations of VC and VB3(amide) added, mainly cross-interactions between vitamin and covitamin determine the strength of solubility increase. To separate these effects and to further reduce experimental effort, electrolyte perturbed-chain statistical association fluid theory was used to predict vitamin solubility. The pH-solubility profiles and the solubilities of vitamins in water at T = 298.15 K and p = 1 bar upon addition of covitamins were predicted with reasonable accuracy. This success resulted from accounting for different charged and neutral vitamin species according to the pH and from considering explicitly the vitamin- water and vitamin-covitamin interactions. It could be shown that hydrotropic solubilization of a vitamin is the increase of vitamin solubility caused by pH shift and by cross-interactions between the saturated species of a vitamin and the added covitamin.

Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 33045-52-2, Name is Methyl 2-methoxy-5-sulfamoylbenzoate, molecular formula is C9H11NO5S, belongs to amides-buliding-blocks compound, is a common compound. In a patnet, author is Davies, Stephen G., once mentioned the new application about 33045-52-2, Computed Properties of https://www.ambeed.com/products/33045-52-2.html.

Mild hydrothermal treatment (245 degrees C) was used to break microalgal cell walls for lipids hydrolysis and solvent-free extraction in batch reactors to obtain biocrude for biodiesel production. Microalgal biocrude obtained through hydrothermal treatment for 10 min had the highest heating value (33.83 MJ/kg), the highest carbon and hydrogen contents (69.63% and 9.39%), and the lowest nitrogen content (3.56%). Fourier transform infrared spectroscopy showed that microalgal biocrude had increased long-chain alkane peaks and disappeared carbohydrate peaks compared to the original microalgal biomass. Thermogravimetric analysis implied that triglycerides in microalgal biomass were hydrolyzed into fatty acids through hydrothermal treatment, while fatty acids and protein hydrolysates reacted to produce amides with higher boiling points. After 10 min subcritical hydrothermal treatment with microalgal solid concentration of 5% at 245 degrees C and esterification reactions (100 degrees C)with methanol and H2SO4 catalysts, the solvent-free lipids extraction efficiency was improved from 69.9% (260 degrees C) to 95.0 wt% without losing the valuable unsaturated fatty acids in microalgae cells. The resulted main compositions of C16:0, C16:1 and C20:5 in microalgal biodiesel reached the highest of 22.7%, 24.1% and 16.2% (based on total lipids in microalgae), much higher than those lipids obtained from 260 degrees C treatment (C20:5 = 6.1%).
