Cytosolic sequestration of the vitamin D receptor as a therapeutic option for vitamin D-induced hypercalcemia

The bioactive vitamin D-3, 1 alpha ,25(OH)(2)D-3, plays a central role in calcium homeostasis by controlling the activity of the vitamin D receptor (VDR) in various tissues. Hypercalcemia secondary to high circulating levels of vitamin D-3 leads to hypercalciuria, nephrocalcinosis and renal dysfunctions. Current therapeutic strategies aim at limiting calcium intake, absorption and resorption, or 1 alpha ,25(OH)(2)D-3 synthesis, but are poorly efficient. In this study, we identify WBP4 as a new VDR interactant, and demonstrate that it controls VDR subcellular localization. Moreover, we show that the vitamin D analogue ZK168281 enhances the interaction between VDR and WBP4 in the cytosol, and normalizes the expression of VDR target genes and serum calcium levels in 1 alpha ,25(OH)(2)D-3-intoxicated mice. As ZK168281 also blunts 1 alpha ,25(OH)(2)D-3-induced VDR signaling in fibroblasts of a patient with impaired vitamin D degradation, this VDR antagonist represents a promising therapeutic option for 1 alpha ,25(OH)(2)D-3-induced hypercalcemia. Current therapeutic strategies for vitamin D-induced hypercalcemia are poorly efficient. Here the authors identify a new interaction between the vitamin D receptor (VDR) and WBP4 controlling the subcellular localization of VDR and show that ZK168281, a VDR antagonist, enhances the interaction between VDR and WBP4 blunting VDR signalling and normalizing calcium levels in vitamin D-intoxicated mice.

Optimization and computational studies evaluating molecular dynamics of EDA cored polymeric dendrimer

In this work we report the results acquired from molecular dynamics simulations as well as the optimization of different generations of polyamidoamine dendrimer. The analysis data revealed synthesized dendrimer as a suitable nanostructured candidate suitable for neutral as well as charged molecule delivery due to the presence of both electrostatic potential and van der Waals forces. The methyl ester terminating groups of half-generation dendrimers with characteristic IR peaks for carbonyl at 1670.41 cm(-1) tends to shift to 1514.17 cm(-1) on conversion to amide group of full-generation dendrimer. The study includes the usage of detailed analysis, demonstrating how molecular dynamics affect the dendrimer complexation. The present investigations provide an unprecedented insight into the computational and experimental system that may be of general significance for the clinical application of dendrimers.

Antiprotozoal activities of Triterpenic Acids and Ester Derivatives Isolated from the Leaves of Vitellaria paradoxa

Leaves of Vitellaria paradoxa , also called Shea butter tree, are used in traditional medicine to treat various symptoms including malaria fever, dysentery, or skin infections. Composition of the dichloromethane extract of V. paradoxa leaves possessing antiparasitic activities was investigated. Five pentacyclic triterpenic acids together with 6 ester derivatives were isolated and identified by standards comparison, MS and (1) H-NMR analysis. Corosolic, maslinic, and tormentic coumaroyl esters and their corresponding triterpenic acids were isolated from this plant for the first time. The antiparasitic activities of the 11 isolated compounds were evaluated in vitro on Plasmodium falciparum, Trypanosoma brucei brucei , and Leishmania mexicana mexicana and their selectivity determined by cytotoxicity evaluation on WI38 cells. None of the isolated compounds showed good antiplasmodial activity. The antitrypanosomal activity of individual compounds was in general higher than their antileishmanial one. One isolated triterpenic ester mixture in equilibrium, 3- O – p-E/Z -coumaroyltormentic acids, showed an attractive promising antitrypanosomal activity (IC (50) =0.7 mu M) with low cytotoxicity (IC (50) = 44.5 mu M) compared to the corresponding acid. Acute toxicity test on this ester did not show any toxicity at the maximal cumulative dose of 100mg/kg intraperitoneally on mice. In vivo efficacy evaluation of this compound, at 50mg/kg by intraperitoneal route on a T.b. brucei -infected mice model, showed a significant parasitemia reduction on day 4 post-infection together with 33.3% survival improvement. Further bioavailability and PK studies are needed along with mode of action investigations to further assess the potential of this molecule.

Digoxin Combined with Aerobic Interval Training Improved Cardiomyocyte Contractility

Digoxin is a cardiotonic that increases the cardiac output without causing deleterious effects on heart, as well as improves the left ventricular performance during physical exercise. We tested whether the association between chronic digoxin administration and aerobic interval training (AIT) promotes beneficial cardiovascular adaptations by improving the myocardial contractility and calcium (Ca (2+)) handling. Male Wistar rats were randomly assigned to sedentary control (C), interval training (T), sedentary digoxin (DIGO) and T associated to digoxin (TDIGO). AIT was performed on a treadmill (1h/day, 5 days/week) for 60 days, consisting of successive 8-min periods at 80% and 20% of VO (2) max for 2 min. Digoxin was administered by orogastric gavage for 60 days. Left ventricle samples were collected to analysis of Ca (2+) handling proteins; contractility and Ca (2+) handling were performed on isolated cardiomyocytes. TDIGO group had a greater elevation in fractional shortening (44%) than DIGO, suggesting a cardiomyocyte contractile improvement. In addition, T or TDIGO groups showed no change in cardiomyocytes properties after Fura2-acetoxymethyl ester, as well as in sarcoplasmic reticulum Ca (2+-) ATPase (SERCA2a), phospholamban and calcineurin expressions. The main findings indicate that association of digoxin and aerobic interval training improved the cardiomyocyte contractile function, but these effects seem to be unrelated to Ca (2+) handling.

Selective photoelectrocatalytic removal of dimethyl phthalate on high-quality expressed molecular imprints decorated specific facet of single crystalline TiO2 photoanode

Elimination of toxic phthalic acid esters from coexisting systems is of great environmental significance. A molecular imprinted highly exposed (111) facet TiO2 surface was constructed for the preferential photoelectrocatalytic oxidation removal of dimethyl phthalate (DMP). The construction of highly exposed (111) facet not only improved photoelectrochemical activity of catalyst, but also provided a uniform and smooth surface that benefits the growth of imprinted sites. During coexisting system with 10-fold concentration of natural organic matters, molecular imprinted (MI) TiO2, (111) NRs could specifically recognize the template and accelerate its oxidizing rate, while inhibit the oxidation of coexisted substances. Meanwhile, DMP can only be 58.3% oxidized on no-molecular imprinted (NI) TiO2, ((111)) NRs in the same system. In situ ATR-FTIR adsorption experiments show that the construction of MI sites significantly improved the adsorption capacity and the selectiveas well as efficient photoelectrocatalytic oxidation performance towards target pollutant by MI TiO2, (111) NRs.

Ester Hydrogenation with Bifunctional Metal-NHC Catalysts: Recent Advances

Hydrogenation of ester to alcohol is an essential reaction in organic chemistry due to its importance in the production of a wide range of bulk and fine chemicals. There are a number of homogeneous and heterogeneous catalyst systems reported in the literature for this useful reaction. Mostly, phosphine-based bifunctional catalysts, owing to their ability to show metal-ligand cooperation during catalytic reactions, are extensively used in these reactions. However, phosphine-based catalysts are difficult to synthesize and are also highly air- and moisture-sensitive, restricting broad applications. In contrast, N-heterocyclic carbenes (NHCs) can be easily synthesized, and their steric and electronic attributes can be fine-tuned easily. In recent times, many phosphine ligands have been replaced by potent sigma-donor NHCs, and the resulting bifunctional metal-ligand systems are proven to be very efficient in several important catalytic reactions. This mini-review focuses the recent advances mainly on bifunctional metal -NHC complexes utilized as (pre)catalysts in ester hydrogenation reactions.

Effect of cooking temperature and time on total phenolic content, total flavonoid content and total in vitro antioxidant activity of garlic

Objective To investigate the effect of cooking temperature and time on the total phenolic content, total flavonoid content and antioxidant activity of aqueous and ethanolic extracts of garlic. Results The mean total phenolic content of fresh garlic were 303.07 +/- 6.58 mg gallic acid equivalent per 100 g (GAE/100 g) and 638.96 +/- 15.30 mg GAE/100 g of plant material for the aqueous and ethanolic extracts respectively. The mean total flavonoid content 109.78 +/- 6.78 mg quercetin equivalent per 100 g (QE/100 g) and 258.47 +/- 12.37 QE/100 g for aqueous and ethanolic extracts respectively. Fourier transform infrared spectral data showed absorptions in the range for carboxylic acids, hydroxyl group, esters, and alcohols, confirming the presence of phenols and flavonoids in the extracts. Cooking temperature had a significant effect on total phenolic content and total flavonoid content while cooking time did not have a significant effect on the phytochemicals and antioxidant activity.

Influence of Patagonian Lactiplantibacillus plantarum and Oenococcus oeni strains on sensory perception of Pinot Noir wine after malolactic fermentation

Background and Aims The aim of this work was to study the effect of two Patagonian malolactic starters, Oenococcus oeni UNQOe 73.2 and Lactiplantibacillus plantarum UNQLp 11, on the wine composition and sensory perception after MLF of Pinot Noir wine. Methods and Results Both strains increased the concentration of procyanidin, diminished the concentration of phenolic substances and increased the colour intensity of the wine after MLF. The volatile profile of both strains differed to that of the Control, particularly the esters, vanillin and some terpenes. The attributes acidity and astringency, black and dried fruits and spicy attributes were features of the wine fermented with both strains. Conclusions Both strains were able to conduct MLF, to increase colour intensity and to change the flavour of the wine with some differences. The wine fermented with UNQLp 11 had a greater frequency of bitterness, whereas the wine fermented with UNQOe 73.2 had a greater frequency of butter. Significance of the Study Knowledge of the effect of Patagonian starter cultures on consumer perception of the wine after fermentation has been improved.

Early Steps of Glycolonitrile Oligomerization: A Free-Energy Map

Building on our previous free-energy map (J. Phys. Chem. A 2018, 122, 6769-6779) examining the reactions of monomeric glycolonitrile, we explore the formation of its dimers and trimers in aqueous solution under neutral conditions. While 5-membered rings are kinetically favored, open-chain oligomers with ester or amide linkages are thermodynamically favored. Accessing the 5-membered rings also provides a potential route to glyoxal that bypasses preforming glycolamide, the thermodynamic sink for monomers. However, finding a kinetically accessible route to glycine starting from glycolonitrile in the absence of added ammonia at room temperature proved challenging; the best case involved an intramolecular nucleophilic substitution reaction in a dimer containing neighboring imine and amide groups. Our free-energy map also examines routes to experimentally proposed moieties, explaining why some are observed in low yield or not at all.

Microorganisms and cationic surfactants

Quaternary ammonium salts (QAS) as cationic surfactants with an amphiphilic structure show biocidal activity against non-pathogenic and pathogenic microorganisms (Gram-positive, Gram-negative bacteria, fungi, as well as lipophilic viruses) occurring in planktonic form or forming biofilms. They can also coat the surface of various materials (glass, metal, silicone, polyester) from which medical devices are made, such as: catheters, implants, heart valves, endoprostheses, and this allows inhibiting the adhesion of microorganisms to these surfaces. In their chemical structure, these surfactants contain labile bonds, e.g. ester or amide bonds, which enable the biodegradation of the compounds. Thanks to this, they are classified as green chemistry. Their biological activity depends on the length of the hydrophobic chain and the structure of the hydrophilic head of the compound. QAS have an affinity for the cell membrane by interacting with its lipids and proteins, which can lead to its disintegration. They have the ability to inhibit the activity of H+-ATPase of the cell membrane, the enzyme responsible for its electrochemical gradient and the transport of nutrients to the cell, e.g. amino acids. These compounds can influence the lipid composition (quantitative and qualitative) of the cell membrane of microorganisms. They are also inhibitors of respiratory processes and can induce the formation of reactive oxygen species. These surfactants are capable of forming micelles and liposomes in an aqueous environment. They are widely used in medicine (as disinfectants, DNA carriers in gene therapy), in industry and environmental protection (as biocides, preservatives) and in agriculture (as fungicides). The widespreaduse of QAS in many fields causes the growing resistance of microorganisms to these compounds. A common mechanism that generates reduced susceptibility to QAS is the presence of efflux pumps.
