Taste signaling is a complex process that is linked to obesity and its associated metabolic syndromes. The sweet taste is mediated through a heterodimeric G protein coupled receptor (GPCR) in a species-specific manner and at multi-tissue specific levels. The sweet receptor recognizes a large number of ligands with structural and functional diversities to modulate different amplitudes of downstream signaling pathway(s). The human sweet-taste receptor has been extremely difficult to study by biophysical methods due to the difficulty in producing large homogeneous quantities of the taste-receptor protein and the lack of reliable in vitro assays to precisely measure productive ligand binding modes that lead to activation of the receptor protein. We report here a multimodal high throughput assay to monitor ligand binding, receptor stability and conformational changes to model the molecular ligand-receptor interactions. We applied saturation transfer difference nuclear magnetic resonance spectroscopy (STD-NMR) complemented by differential scanning calorimetry (DSC), circular dichroism (CD) spectroscopy, and intrinsic fluorescence spectroscopy (IF) to characterize binding interactions. Our method using complementary NMR and biophysical analysis is advantageous to study the mechanism of ligand binding and signaling processes in other GPCRs.

Millet plays a major role in food security in Africa and Asia. In addition to being a rich source of nutrients, millet contains many phytochemicals that are potentially beneficial for human health, and several of these compounds are related to its cooking properties. In this study, 172 metabolites and 3 cooking quality traits of millet from the same two cultivars grown both organically and conventionally were analyzed. The results indicated that the differences in the metabolities and cooking quality of the millets could be attributed mostly to the cultivar and whether the millet was grown conventionally or organically. Organic growing conditions only enhanced the accumulation of some carbohydrates such as fructose and glucose. Therefore, cultivar selection was important in organic millet cultivation. The relationships between metabolites and cooking quality traits showed that, overall, 57.43% of the variation in the cooking quality matrix was explained by metabolome matrix, which indicated that some chemical compounds could also be used to evaluate the cooking qualities of millet. These results could contribute to breeding millet to improve its the nutritional properties and cooking qualities.

Xanthine oxidase (XO) is the key enzyme in humans which is related to a variety of diseases such as gout, hyperuricemia and cardiovascular diseases. In this work, a series of 2-arylbenzo[b]furan derivatives were synthesized based on salvianolic acid C, and they were evaluated for xanthine oxidase inhibitory and antioxidant activities. Compounds 5b, 6a, 6e and 6f showed potent xanthine oxidase inhibitory activities with IC50values ranging from 3.99 to 6.36 muM, which were comparable with that of allopurinol. Lineweaver-Burk plots analysis revealed that the representative derivative 6e could bind to either xanthine oxidase or the xanthine oxidase-xanthine complex, which exhibited a mixed-type competitive mechanism. A DPPH radical scavenging assay showed most of the hydroxyl-functionalized 2-arylbenzo[b]furan derivatives possessed the potent antioxidant activity, which was further validated on LPS-stimulated RAW 264.7 macrophages model. The structure-activity relationships were preliminary analyzed and indicated that the structural skeleton of 2-arylbenzo[b]furan and phenolic hydroxyl groups played an important role in maintaining xanthine oxidase inhibitory effect and antioxidant property for the series of derivatives. Meanwhile, molecular docking studies were performed to further confirm the structure-activity relationships and investigate the proposed binding mechanisms of compounds 5d, 6d and 10d binding to the protein.

The activation of the beta-class carbonic anhydrases (CAs, EC 4.2.1.1) from the bacteria Brucella suis and Francisella tularensis with amine and amino acids was investigated. BsuCA 1 was sensitive to activation with amino acids and amines, whereas FtuCA was not. The most effective BsuCA 1 activators were L-adrenaline and D-Tyr (KAs of 0.70?0.95 muM). L-His, L-/D-Phe, L-/D-DOPA, L-Trp, L-Tyr, 4-amino-L-Phe, dopamine, 2-pyridyl-methylamine, D-Glu and L-Gln showed activation constants in the range of 0.70?3.21 muM. FtuCA was sensitive to activation with L-Glu (KA of 9.13 muM). Most of the investigated compounds showed a weak activating effect against FtuCA (KAs of 30.5?78.3 muM). Many of the investigated amino acid and amines are present in high concentrations in many tissues in vertebrates, and their role in the pathogenicity of the two bacteria is poorly understood. Our study may bring insights in processes connected with invasion and pathogenic effects of intracellular bacteria.

The beta-carbonic anhydrase from Saccharomyces cerevisiae (CA, EC 4.2.1.1), scCA, which is encoded by the Nce103 gene, is an effective catalyst for CO2 hydration to bicarbonate and protons, with a kcat of 9.4 x 105 s-1, and kcat/KM of 9.8 x 107 M-1.s-1. Its inhibition with anions and sulfonamides has been investigated, as well as its activation with amines and amino acids. Bromide, iodide and sulfamide, were the best anion inhibitors, with KIs of 8.7 – 10.8 muM. Benzenesulfonamides substituted in 2-, 4- and 3,4-positions with amino, alkyl, halogeno and hydroxyalkyl moieties had KIs in the range of 0.976 – 18.45 muM. Better inhibition (KIs in the range of 154 – 654 nM) was observed for benzenesulfonamides incorporating aminoalkyl/carboxyalkyl moieties or halogenosulfanilamides; benzene- 1,3-disulfonamides; simple heterocyclic sulfonamides and sulfanilyl-sulfonamides. The clinically used sulfonamides/sulfamate (acetazolamide, ethoxzolamide, methazolamide, dorzolamide, topiramate, celecoxib, etc.) generally showed effective scCA inhibitory activity, with KIs in the range of 82.6 – 133 nM. The best inhibitor (KI of 15.1 nM) was 4-(2-amino-pyrimidin-4-yl)-benzenesulfonamide. Ladrenaline and some piperazines incorporating aminoethyl moieties were the most effective scCA activators. These studies may lead to a better understanding of the role of this enzyme in yeasts/fungi, and since the Nce103 gene is also present in many pathogenic organisms (Candida spp., Cryptococcus neoformans, etc) they may be useful to develop antifungal drugs.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Electric Literature of 153-94-6, you can also check out more blogs about153-94-6

The ternary copper(II) complexes [Cu(l-trp)(bpy)](ClO4) (1) and [Cu(l-trp)(phen)] (ClO4) · 3H2O (2) (where l-trp = l-tryptophan, bpy = bipridyl, phen = phenanthroline) have been synthesized. The single crystal X-ray structures for these complexes revealed that the monocationic CuII-units are interlinked through Cu-OCO-Cu connectivity and exist as helical coordination polymers. The two different helical strands composed with Cu1 and Cu2 independently, possess a similar pitch distance of 7.713 A? in complex 1. For complex 2, existing in the hydrated form, the Cu(II) polymeric strand and the hydrated water molecules have gained a supramolecular helical architecture with a similar pitch distance of 8.133 A?. The two helical strands in complex 1 are associated with right handed (PP) supramolecular chirality, while the helical water chain and the CuII-strand in 2 are self assembled into left handed (MM) helicity in the solid state. The solid state CD recorded for 1 and the dehydrated form of 2 exhibit a positive optical sign at their respective d-d band [lambdamax = 667 nm, 1; lambdamax = 630 nm, 2], the solution state CD for both these complexes are found to be inverted into a negative optical sign, which could be attributed to inversion of their associated supramolecular helicity. The TGA curve illustrates two distinct weight losses at 60 C and 87 C, equivalent to one and two water molecules, respectively. The PXRD pattern for the hydrated and dehydrated forms of 2 indicated a change, on comparison with the simulated diffractograph. The fluorescence properties of both these complexes, possessing tryptophan and bipy/phen, were investigated.

This study explored the effect of the Maillard reaction on the Co-Hydrothermal Liquefaction (HTL) of two different microalgae strains for bio-crude production. Model compounds, glucose and soya protein were mixed at different ratios and HTL was run at different temperatures to investigate the mechanism of the Maillard reaction. Pure Nannochloropsis (Nan), Spirulina (Spi) and the mixture of the two microalgae strains at the ratio of 1 : 1 (oven dry weight basis) were hydrothermally converted under the same reaction conditions for comparison. The mixtures of model compound and microalgae were also subjected to HTL to investigate the effects of chemical compounds on bio-crude yield. The Co-HTL for Nan and Spi exhibited lower bio-crude yield than that of HTL for individual microalgae. A high protein content has a negative effect on the fatty acid recovery. The dosage of glucose could enhance the bio-crude yield during HTL because of the Maillard reaction with protein. In addition, the results of elemental analysis indicated that the glucose dosage had promoted the energy recovery during HTL; FTIR and GC-MS spectra of bio-crudes revealing that tailoring the ratio between glucose and protein could elevate the quality of bio-crude from microalgae, especially for the microalgae with a low lipid content.

An activation study of the human carbonic anhydrase (hCA, EC 4.2.1.1) isozymes VII and XIV using a small library of natural/non-natural amino acids and aromatic/heterocyclic amines is reported. hCA VII was efficiently activated by l-/d-His, dopamine and serotonin (KAs of 0.71-0.93 muM). The best hCA XIV activators were histamine (KA of 10 nM), l-Phe, l-/d-His and 4-amino-l-Phe (KAs of 0.24-2.90 muM). In view of the significant expression levels of CA VII and CA XIV in the brain, selective activation of these isoforms may be useful when developing pharmacologic agents for the management of major disorders such as epilepsy and Alzheimer’s disease.

The diversity of yeasts and filamentous fungi in muds from hypersaline alkaline lakes of Wadi El- Natrun and fresh water of the Nile River and Ibrahimia Canal was evaluated. The mean pH of saline water mud was 9.21, but fresh water mud registered 8.07. A total of 193 species (two varieties were distinguished in two of them) belonging to 67 genera were recovered from both muds investigated on DRBC (55 genera, 164 species), DG18 (36 genera, 117 species) and MY50G (23 genera, 76 species) media. From these, 17 species assigned to 12 genera were yeasts and 176 species and 2 varieties assigned to 55 genera were filamentous fungi. The highest numbers of fungal propagules were recovered on DRBC from freshwater mud, while the lowest on MY50G from saline water mud. Yeasts constituted a small proportion of all propagules from the two mud types on all three media, whereas filamentous fungi were the major component. However, freshwater mud samples yielded higher numbers of yeast genera and species using all three media. Candida was common in freshwater mud and rare in saline water mud, while Meyerozyma and Rhodotorula were infrequent in both muds. The remaining yeast species were recovered from freshwater mud only. Aspergillus (46 species) was the most common genus of filamentous fungi encountered in all samples, ranging in frequency from 39.82% to 96.62%; A. terreus, A. flavipes and A. niger dominated in both types of mud. Cladosporium (9 species), Fusarium (8 species), Penicillium (18 species) and Scopulariopsis (7 species) were encountered in both types of mud. Notably, 47 filamentous species were isolated only on the media with lower water activity (DG18, MY50G).
