Characterization and evaluation of nanoencapsulated diethylcarbamazine in model of acute hepatic inflammation

Previous studies from our laboratory have demonstrated that Diethylcarbamazine (DEC) is a potent anti-inflammatory drug. The aim of the present study was to characterize the nanoencapsulation of DEC and to evaluate its effectiveness in a model of inflammation for the first time. C57BL/6 mice were divided into six groups: 1) Control; 2) Carbon tetrachloride (CCl4); 3) DEC 25 mg/kg + CCl4; 4) DEC 50 mg/kg + CCl4; 5) DEC-NANO 05 mg/kg + CCl4 and 6) DEC-NANO 12.5 mg/kg + CCl4. Liver fragments were stained with hematoxylin-eosin, and processed for Western blot, ELISA and immunohistochemistry. Serum was also collected for biochemical measurements. Carbon tetrachloride induced hepatic injury, observed through increased inflammatory markers (TNF-alpha, IL-1beta, PGE2, COX-2 and iNOS), changes in liver morphology, and increased serum levels of total cholesterol, triglycerides, TGO and TGP, LDL, as well as reduced HDL levels. Nanoparticles containing DEC were characterized by diameter, polydispersity index and zeta potential. Treatment with 12.5 nanoencapsulated DEC exhibited a superior anti-inflammatory action to the DEC traditional dose (50 mg/kg) used in murine assays, restoring liver morphology, improving serological parameters and reducing the expression of inflammatory markers. The present formulation of nanoencapsulated DEC is therefore a potential therapeutic tool for the treatment of inflammatory hepatic disorders, permitting the use of smaller doses and reducing treatment time, while maintaining high efficacy.

Designing antifilarial drug trials using clinical trial simulators

Lymphatic filariasis and onchocerciasis are neglected tropical diseases (NTDs) targeted for elimination by mass (antifilarial) drug administration. These drugs are predominantly active against the microfilarial progeny of adult worms. New drugs or combinations are needed to improve patient therapy and to enhance the effectiveness of interventions in persistent hotspots of transmission. Several therapies and regimens are currently in (pre-)clinical testing. Clinical trial simulators (CTSs) project patient outcomes to inform the design of clinical trials but have not been widely applied to NTDs, where their resource-saving payoffs could be highly beneficial. We demonstrate the utility of CTSs using our individual-based onchocerciasis transmission model (EPIONCHO-IBM) that projects trial outcomes of a hypothetical macrofilaricidal drug. We identify key design decisions that influence the power of clinical trials, including participant eligibility criteria and post-treatment follow-up times for measuring infection indicators. We discuss how CTSs help to inform target product profiles.

Arginine and proline applied as food additives stimulate high freeze tolerance in larvae of Drosophila melanogaster

The fruit fly Drosophila melanogaster is an insect of tropical origin. Its larval stage is evolutionarily adapted for rapid growth and development under warm conditions and shows high sensitivity to cold. In this study, we further developed an optimal acclimation and freezing protocol that significantly improves larval freeze tolerance (an ability to survive at -5C when most of the freezable fraction of water is converted to ice). Using the optimal protocol, freeze survival to adult stage increased from 0.7% to 12.6% in the larvae fed standard diet (agar, sugar, yeast, cornmeal). Next, we fed the larvae diets augmented with 31 different amino compounds, administered in different concentrations, and observed their effects on larval metabolomic composition, viability, rate of development and freeze tolerance. While some diet additives were toxic, others showed positive effects on freeze tolerance. Statistical correlation revealed tight association between high freeze tolerance and high levels of amino compounds involved in arginine and proline metabolism. Proline- and arginine-augmented diets showed the highest potential, improving freeze survival to 42.1% and 50.6%, respectively. Two plausible mechanisms by which high concentrations of proline and arginine might stimulate high freeze tolerance are discussed: (i) proline, probably in combination with trehalose, could reduce partial unfolding of proteins and prevent membrane fusions in the larvae exposed to thermal stress ( prior to freezing) or during freeze dehydration; (ii) both arginine and proline are exceptional among amino compounds in their ability to form supramolecular aggregates which probably bind partially unfolded proteins and inhibit their aggregation under increasing freeze dehydration.

Effects of mono- and dialkylglucosides on the characterisation and blood circulation of lipid nanoemulsions

Aim: Effects of two cosurfactants, n-alkylglycosides with mono- or disaccharide groups?N-nonyl beta-D-glucopyranoside (N-Glu) and N-decyl beta-D-maltoside (D-Mal)?were studied to the stability in saline solution, interaction with serum albumin, and blood circulation of the lipid nanoemulsion (LNE). Methods: The LNEs composed of soybean oil, phosphatidylcholine, and sodium palmitate were prepared without (Control-LNE) and with N-Glu or D-Mal (NG-LNE and DM-LNE, respectively). Results: In saline solution, NG-LNE exhibited a smaller droplet size than Control-LNE, while the size of DM-LNE was significantly increased compared with the other LNEs. The fluorescence resonance energy transfer method showed that the order of albumin interaction was DM-LNE > NG-LNE > Control-LNE. In vivo blood circulation in mice, showed greater fractions of both NG-LNE and DM-LNE remaining in blood over time compared with Control-LNE. Conclusions: The nature of high stability in saline solution and high affinity for serum albumin led to the prolonged circulation of LNE.

Natural magnesium oxide (MgO) catalysts: A cost-effective sustainable alternative to acid zeolites for the in situ upgrading of biomass fast pyrolysis oil

The thermal and catalytic fast pyrolysis of biomass aims at the production of pyrolysis oil (bio-oil), which can be utilized as a source of chemicals or as a bio-crude for the production of hydrocarbon fuels. We investigated low-cost, naturally derived basic MgO materials as catalysts for the catalytic fast pyrolysis of lignocellulosic biomass as alternatives to classical acidic zeolite catalysts. The MgO catalysts were produced from natural magnesite mineral without any significant treatment besides calcination, crushing and sieving. Their structure, composition, porosity, morphology and surface properties were thoroughly examined by XRD, XRF, N2 porosimetry, SEM, TEM, TPD-CO2 and TPD-NH3. The physicochemical characteristics of the MgO catalysts depended mainly on the different production conditions (duration and temperature of calcination). Despite their negligible acidity, the MgO catalysts effectively reduced the oxygen content of the produced bio-oil and exhibited similar or even better performance compared to that of an industrial ZSM-5 catalyst formulation (i.e. non-catalytic pyrolysis: 38.9 wt.% organic bio-oil with 38.7 wt.% O2; ZSM-5 based catalyst: 20.7 wt.% organic bio-oil with 30.9 wt.% O2; selected natural MgO catalysts: 25.7 wt.% organic bio-oil with 31.0 wt.% O2 or 21.1 wt.% organic bio-oil with 28.4 wt.% O2). The basic sites of the MgO catalysts favored reduction of acids and deoxygenation via ketonization and aldol condensation reactions, as indicated by the product distribution and the composition of the bio-oil. Oxygen was removed mainly via the preferred pathway of CO2 formation, compared to CO and water as in the case of ZSM-5 zeolite. On the other hand, reaction coke slightly increased over the MgO catalysts as compared to ZSM-5; however, the MgO formed coke was oxidized/burnt at significantly lower temperatures compared to that of ZSM-5, thus enabling MgO regeneration by relatively mild calcination in air. A systematic correlation of product yields and oxygen content of bio-oil with the physicochemical properties of the MgO catalysts has been established.

Mononuclear mercury(II) complexes containing bipyridine derivatives and thiocyanate ligands: Synthesis, characterization, crystal structure determination, and luminescent properties

A series of mercury(II) complexes, [Hg(N[sbnd]N)(SCN)2] (N[sbnd]N is 4,4?-dimethyl-2,2?-bipyridine in 1, 5,5?-dimethyl-2,2?-bipyridine in 2, 6,6?-dimethyl-2,2?-bipyridine in 3 and 6-methyl-2,2?-bipyridine in 4), were prepared from the reactions of Hg(SCN)2 with mentioned ligands in methanol. Suitable crystals of these complexes were obtained for X-ray diffraction measurement by methanol diffusion into a DMSO solution. The four complexes were thoroughly characterized by spectral methods (IR, UV?Vis, 13C{1H}NMR, 1H NMR and luminescence), elemental analysis (CHNS) and single crystal X-ray diffraction. The X-ray structural analysis indicated that in the structures of these complexes, the mercury(II) cation is four-coordinated in a distorted tetrahedral configuration by two S atoms from two thiocyanate anions and two N atoms from one chelating 2,2?-bipyridine derivative ligand. Also, in these complexes intermolecular interactions, for example C[sbnd]H?N hydrogen bonds (in 1?4), C[sbnd]H?S hydrogen bonds (in 1, 2 and 4), pi ? pi interactions (in 2?4), Hg?N interactions (in 2) and S?S interactions (in 4), are effective in the stabilization of the crystal structures and the formation of the 3D supramolecular complexes. Furthermore, the luminescence spectra of the title complexes show that the intensity of their emission bands are stronger than the emission bands for the free bipyridine derivative ligands.

Cytotoxic titanium(IV) complexes of chiral diaminobis(phenolato) ligands: Better combination of activity and stability by the bipyrrolidine moiety

Racemic and enantiomerically pure titanium(IV) complexes with ortho-bromo-para-methyl-substituted diaminobis(phenolato) ligands were prepared with NH-, NMe-, and bipyrrolidine-based diamino bridges through ligand-to-metal chiral induction. The hydrolytic stability of the complexes was evaluated, and their cytotoxicity was measured using HT-29 human colon cancer cells based on the MTT assay. All stereochemical forms of the NMe-based complexes, although demonstrating the highest hydrolytic stability, were biologically inactive. For the NH and bipyrrolidine-based active complexes, the pure enantiomers exhibited high cytotoxicity whereas the racemic mixtures were inactive, supporting the involvement of a polynuclear active species. The bipyrrolidine complexes appear to provide the best combination of hydrolytic stability and biological activity, presumably by minimizing steric bulk and consequently enabling biological accessibility. Racemic and optically pure phenolato titanium(IV) complexes were prepared with NH, NMe, and bipyrrolidine-based diamino bridges. The optically pure bipyrrolidine complexes provide the best combination of hydrolytic stability and biological activity, presumably by maintaining small enough steric bulk to enable biological accessibility.
