Nanocrystals: A perspective on translational research and clinical studies

Poorly soluble small molecules typically pose translational hurdles owing to their low solubility, low bioavailability, and formulation challenges. Nanocrystallization is a versatile method for salvaging poorly soluble drugs with the added benefit of a carrier-free delivery system. In this review, we provide a comprehensive analysis of nanocrystals with emphasis on their clinical translation. Additionally, the review sheds light on clinically approved nanocrystal drug products as well as those in development.

Synergism and aggregation behaviour in an aqueous binary mixture of cationic-zwitterionic surfactants: Physico-chemical characterization with molecular simulation approach

Aqueous interactions between a cationic surfactant benzyl dimethylhexadecylammonium chloride (BDHAC) and alkyldimethylammoniopropane sulfonates (CnDAPS) based three zwitterionic surfactants n = 10, 12, and 14 (abbreviated as C10DAPS, C12DAPS and C14DAPS, respectively) were studied using tensiometry, and fluorescence spectrophotometry techniques. The critical micelle concentration degree of synergism and various other parameters such as interaction parameter (beta), activity coefficients (fm) and interfacial parameters such as surface pressure (piCMC), packing parameter (P), surface excess concentration (Gammamax), surface tension at CMC (gammaCMC), and minimum area per molecule (Amin) were evaluated using the Regular Solution Theory (RST) of mixed systems. The results indicate a strong dependency on the mixed system and their composition. For the quantitative prediction, the molecular architecture of the surfactants in mixed systems and their synergistic interactions were investigated by computational simulation using Spartan’14 V1.1.8. The structural optimization results obtained were found to be in good agreement with the estimations made using RST. The reduction in surface tension indicates a certain efficiency in mixed micelle formation owing to electrostatic attraction between the cationic and zwitterionic surfactants. In addition, the binary surfactant systems evaluated by Maeda’s approach infer the mixed micelles are thermodynamically stable. The aggregation number (Nagg) appeared to be larger at the composition point where the efficiency of mixed micelle formation is greatest. The strength of the interaction between BDHAC and CnDAPS followed the order: C14DAPS > C12DAPS > C10DAPS indicating a greater synergism at 0.25 molar ratio of zwitterionic surfactants to cationic surfactants in the aqueous solution at 303.15 K.

Anisotropic gold nanoparticles: Preparation and applications in catalysis

Despite the high amount of scientific work dedicated to the gold nanoparticles in catalysis, most of the research has been performed utilising supported nanoparticles obtained by traditional impregnation of gold salts onto a support, co-precipitation or deposition-precipitation methods which do not benefit from the recent advances in nanotechnologies. Only more recently, gold catalyst scientists have been exploiting the potential of preforming the metal nanoparticles in a colloidal suspension before immobilisation with great results in terms of catalytic activity and the morphology control of mono- and bimetallic catalysts. On the other hand, the last decade has seen the emergence of more advanced control in gold metal nanoparticle synthesis, resulting in a variety of anisotropic gold nanoparticles with easily accessible new morphologies that offer control over the coordination of surface atoms and the optical properties of the nanoparticles (tunable plasmon band) with immense relevance for catalysis. Such morphologies include nanorods, nanostars, nanoflowers, dendritic nanostructures or polyhedral nanoparticles to mention a few. In addition to highlighting newly developed methods and properties of anisotropic gold nanoparticles, in this review we examine the emerging literature that clearly indicates the often superior catalytic performance and amazing potential of these nanoparticles to transform the field of heterogeneous catalysis by gold by offering potentially higher catalytic performance, control over exposed active sites, robustness and tunability for thermal-, electro- and photocatalysis.

Determination of benzalkonium chloride by chemical ionization mass spectroscopy

A new specific and sensitive method of analysis for samples of benzalkonium chlorides is presented. Chemical-ionization mass spectroscopy has been used to identify and determine the proportions of various alkyl chain lengths in commercial mixtures of benzalkonium chlorides. This method allows the direct and simultaneous determination of individual benzalkonium chlorides.

Influence of Anionic and Cationic Reverse Micelles on Nucleophilic Aromatic Substitution Reaction between 1-Fluoro-2,4-dinitrobenzene and Piperidine

The nucleophilic aromatic substitution (SNAr) reaction between 1-fluoro-2,4-dinitrobenzene and piperidine (PIP) were studied in two different reverse micellar interfaces: benzene/sodium 1,4-bis(2-ethylhexyl) sulfosuccinate (AOT)/water and benzene/benzyl-n-hexadecyl dimethylammonium chloride (BHDC)/water reverse micellar media. The kinetic profiles of the reactions were investigated as a function of variables such as surfactant and amine concentration and the amount of water dispersed in the reverse micelles, W0 = [H2O]/[surfactant]. In the AOT system at W0 = 0, no micellar effect was observed and the reaction takes place almost entirely in the benzene pseudophase, at every AOT and PIP concentration. At W0 = 10, a slight increment of the reaction rate was observed at low [PIP] with AOT concentration, probably due to the increase of micropolarity of the medium. However, at [PIP] ? 0.07 M the reaction rates are always higher in pure benzene than in the micellar medium because the catalytic effect of the amine predominates in the organic solvent. In the BHDC system the reaction is faster in the micellar medium than in the pure solvent. Increasing the BHDC concentration accelerates the overall reaction, and the saturation of the micellar interface is never reached. In addition, the reaction is not base-catalyzed in this micellar medium. Thus, despite the partition of the reactants in both pseudophases the reactions effectively take place at the interface of the aggregates. The kinetic behavior can be quantitatively explained taking into account the distribution of the substrate and the nucleophile between the bulk solvent and the micelle interface. The results were used to evaluate the amine distribution constant between the micellar pseudophase and organic solvent and the second-order rate coefficient of SNAr reaction in the interface. A mechanism to rationalize the kinetic results in both interfaces is proposed.

Gold Nanoparticles Functionalized with Fully Conjugated Fullerene C60 Derivatives as a Material with Exceptional Capability of Absorbing Electrons

We report a highly electron-absorbing material (“electron-sponge”) obtained by coupling gold nanoparticles (AuNPs, 8 nm in diameter) with fullerene C60 spheres by fully conjugated linker molecules. This goal has been achieved through synthesis of a new class of conducting thionoester-substituted and thioketone-substituted azahomo-[60]fullerenes. The obtained C60 derivatives have been found to possess the capability of binding covalently to the surface of gold. Thus, for the first time, we show that thioketone and thionoester moieties can be successfully employed as new anchoring groups for conjugated fullerene derivatives. High-resolution X-ray photoelectron spectroscopy studies have revealed that the ligands are attached to the gold surface of AuNPs through strong Au-S bonding. One of the synthesized C60 derivatives, O-butyl 4-(azahomo(C60-Ih)fullerene)benzothioate (C60-BCT-OBu), has been investigated in detail. The C60-BCT-OBu-coated AuNPs form a highly insoluble precipitate, which can be easily dissolved in toluene into individual AuNPs using cationic surfactants. The precipitate has been found to exhibit an extraordinary capability of absorbing electrons. A single AuNP can absorb on average about 4500 electrons in an experimental condition in which tetrahydrofuran suspension of the precipitate of the C60-BCT-OBu-coated AuNPs is charged in a lithium naphthalide-mediated process. The electrical properties of the AuNPs are successfully explained by a model in which the C60-BCT-OBu-coated AuNP is represented by an equipotential heterostructure composed of C60 spheres connected with the gold AuNP core by conducting linkers.

Quantitative structure activity relationships. II. A mixed approach, based on Hansch and Free Wilson analysis

Based on the theoretical and numerical equivalence of Hansch’s linear multiple regression model and the modified Free Wilson model a mixed approach is developed. The mixed approach is a combination of both models which makes use of the advantages of each model and widens the applicability of Hansch and Free Wilson analysis. The Free Wilson approach now is applicable also in the case of parabolic dependence of biological activity on a particular physical property, e.g., log P or pi. A rational explanation is given for the use of dummy variables in Hansch equations and the derivation of Hansch correlations for de novo group contributions obtained from Free Wilson analysis. Some examples illustrate the mixed approach and demonstrate its usefulness to establish biologically meaningful structure activity relationships.

Liquid chromatography-tandem mass spectrometry multiresidue method for the analysis of quaternary ammonium compounds in cheese and milk products: Development and validation using the total error approach

Quaternary ammonium compounds (QACs) are both cationic surfactants and biocidal substances widely used as disinfectants in the food industry. A sensitive and reliable method for the analysis of benzalkonium chlorides (BACs) and dialkyldimethylammonium chlorides (DDACs) has been developed that enables the simultaneous quantitative determination of ten quaternary ammonium residues in dairy products below the provisional maximum residue level (MRL), set at 0.1mgkg-1. To the best of our knowledge, this method could be the one applicable to milk and to three major processed milk products selected, namely processed or hard pressed cheeses, and whole milk powder. The method comprises solvent extraction using a mixture of acetonitrile and ethyl acetate, without any further clean-up. Analyses were performed by liquid chromatography coupled with electrospray tandem mass spectrometry detection (LC-ESI-MS/MS) operating in positive mode. A C18 analytical column was used for chromatographic separation, with a mobile phase composed of acetonitrile and water both containing 0.3% formic acid; and methanol in the gradient mode. Five deuterated internal standards were added to obtain the most accurate quantification. Extraction recoveries were satisfactory and no matrix effects were observed. The method was validated using the total error approach in accordance with the NF V03-110 standard in order to characterize the trueness, repeatability, intermediate precision and analytical limits within the range of 5-150mugkg-1 for all matrices. These performance criteria, calculated by e.noval 3.0 software, were satisfactory and in full accordance with the proposed provisional MRL and with the recommendations in the European Union SANTE/11945/2015 regulatory guidelines. The limit of detection (LOD) was low (<1.9mugkg-1) and the limit of quantification (LOQ) ranged from 5mugkg-1 to 35mugkg-1 for all matrices depending on the analytes.The validation results proved that the method is suitable for quantifying quaternary ammoniums in foodstuffs from dairy industries at residue levels, and could be used for biocide residues monitoring plans and to measure the exposition consumer to biocides products. The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 122-18-9 is helpful to your research. Synthetic Route of 122-18-9
