Introduction: Orally disintegrating tablets (ODTs) provide an important treatment option for pediatric, geriatric and psychiatric patients. In our previous study, we have performed the initial studies for the formulation development and characterization of new ODT formulations containing a bitter taste drug, mirtazapine, coated with 6% (w/w) Eudragit E-100 (first group of formulations, FGF) without taste evaluation. In present study, coating ratio of the drug was increased to 8% (w/w) (second group of formulations, SGF) to examine the effect of increased coating ratio of drug on in vitro characterization of the formulations including in vitro taste masking study. Materials and methods: Coacervation technique using Eudragit E-100 was employed to obtain taste-masked mirtazapine granules. FGF and SGF were compared to original product (Remeron SolTab, an antidepressant drug which produced by pellet technology) in terms of in vitro permeability, in vitro taste masking efficiency which was performed by dissolution studies in salivary medium and dissolution stability. Also, the other tablet characteristics (such as diameter, thickness) of SGF were examined. Results and discussion: The disintegration time of the SGF were found as A1 < A2 < A3 < A5 < A4 (8% Eudragit E-100), but all of the formulations dissolved under 30 seconds and friability values were less than 1%. In vitro taste masking efficiency studies demonstrated that C2 formulation (in FGF) had the most similar dissolution profile to Remeron SolTab. Conclusions: According to these findings, B2 or C2 (with citric acid or sodium bicarbonate, respectively, with 6% Eudragit E-100) formulations could be promising alternatives to Remeron SolTab.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 64519-82-0, Name is (3R,4R,5R)-6-(((2S,3R,4S,5S,6R)-3,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexane-1,2,3,4,5-pentaol, Recommanded Product: 64519-82-0.

Dry foam technology was developed as alternative granulation technique to overcome insufficient oral bioavailability of poorly soluble and wettable active pharmaceutical ingredients (APIs). In recent studies the type of filler showed to have a distinct influence on dry foam morphology as well as dissolution characteristics. Isomalt for instance improved the initial dissolution rate of fenofibrate dry foam formulation tablets. In this study the hypothesis that fast dissolving low molecular weight fillers improve dissolution rate and alter dry foam morphology should be confirmed with two APIs with different aqueous solubility (indomethacin, orlistat), in three different filler combinations, namely maltodextrin 21D, isomalt and 1:1 mixture of mannitol and maltodextrin 21D. In addition the dissolution behaviour of dry foam tablets was compared to fluid bed granulation formulations with the same drug loading and to an orlistat marketed formulation (Alli 60. mg capsules) in FaSSIF using USP 2 paddle apparatus and HPLC analysis after filtration.Dry foams prepared with low molecular weight fillers revealed more compact and less porous structures compared to dry foams containing maltodextrin 21D. Interestingly, their rough surface still resulted in increased surface area compared to the other formulations. The initial dissolution behaviour of indomethacin and orlistat dry foam tablets was improved by using isomalt and the mannitol-maltodextrin mixture as filler. All indomethacin formulations reached complete dissolution of the applied dose, whereas the total amount of dissolved orlistat was increased compared to the fluid bed granule tablets and the marketed formulation Alli by using low molecular weight fillers in dry foam formulations. The improved dissolution behaviour of Orlistat dry foam tablets using low molecular weight fillers was additionally confirmed in USP monography dissolution medium.

Supramolecular organogels fabricated with dicarboxylic acids and primary alkyl amines: controllable self-assembled structures

Supramolecular organogels are soft materials comprised of low-molecular-mass organic gelators (LMOGs) and organic liquids. Owning to their unique supramolecular structures and potential applications, LMOGs have attracted wide attention from chemists and biochemists. A new superorganogel system based on dicarboxylic acids and primary alkyl amines (R-NH2) from the formation of organogels is achieved in various organic media including strong and weak polar solvents. The gelation properties of these gelators strongly rely on the molecular structure. Their aggregation morphology in the as-obtained organogels can be controlled by the solvent polarity and the tail chain length of R-NH2. Interestingly, flower-like self-assemblies can be obtained in organic solvents with medium polarity, such as tetrahydrofuran, pyridine and dichloromethane, when the gelators possess a suitable length of carbon chain. Moreover, further analyses of Fourier transformation infrared spectroscopy and(1)H nuclear magnetic resonance spectroscopy reveal that the intermolecular acid-base interaction and van der Waals interaction are critical driving forces in the process of organogelation. In addition, this kind of organogel system displays excellent mechanical properties and thermo-reversibility, and its forming mechanism is also proposed.

Ru-Catalyzed Cross Dehydrogenative Coupling Leading to Si-O and Si-S Bond Formations and Also Stimulating an Alternative Scope for Hydrogenation of C=O, C=N and N=N Bonds

Reaction pathways involved in catalytic Cross Dehydrogenative Coupling (CDC) reactions leading to formation of Si-O and Si-S bonds have been formulated and explored theoretically using Density Functional Theory (DFT). The advantage of the weak Si-H bond has been exploited to carry out coupling with water, alcohol and thiol, along with H-2 release. Ru complex, [K(dme)(2)][Ru(H)(trop(2)dad)] when reacts with water generates a neutral complex, [Ru(trop(2)dad)]. This neutral complex has been employed to act as a catalyst in CDC reactions. It has also been found that the complex, [Ru(H-2)(trop(2)dad)] formed within the catalytic cycle may also be used for hydrogenation of C=O, C=N and N=N bonds. The optimized geometries of all the complexes and transition states have been obtained using wB97xd functional in conjunction with 6-31++G(d,p) basis set. The whole assisting phenomena in solvent medium has been investigated through the implementation of conductor-like screening solvation model (COSMO) considering tetrahydrofuran as the bulk solvent medium. The Turnover frequency (TOF) has been calculated by Energetic Span Model. The theoretical investigation extends the role of the ruthenium catalyst to the regime of ‘element to element’ bond formation, along with H-2 release, which may be significant in the field of energy storage, and also triggers an alternative possibility of hydrogenation of carbonyls, imines and diazo compounds.

Investigation on thermophysical properties of binary systems of [C(4)mim [NTf2] with cyclic ethers: Application of PFP and ERAS theories

Room temperature ionic liquids (RTILs) have been researched as a novel substitute for volatile organic solvents since their inception two decades ago. The high viscosity and cost of pure !Bare major constrains for their industrial application which can be overcome by the addition of small amount of organic solvent. The introduction of organic solvents in pure ILs makes noticeable alteration in thermophysical properties of pure IL through variations in the molecular interactions. This manuscript deals with the excess molar volumes V-m(E), excess molar isentropic compressibili ties K-s,m(E) and logarithm of viscosi ties In eta(m) for binary systems of 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C(4)mim][NTf2]) with two cyclic ethers: tetrahydrofuran (THF) and 1,4 dioxane (D10), at entire mole fraction range of IL and temperature between 298.15 K to 323.15 K. The V-m(E), K-s,m(E) and In eta(m) were calculated from the experimental values of densities, rho, speeds of sound, u, and viscosities, eta, respeclively. The Redlich-Kister polynomial equation was utilized to obtain fitting parameters for V-m(E), K-s,m(E) and In eta(m). The values of V-m(E), K-s,m(E) and In eta(m) were negative. The negative deviation from ideality was ascribed to efficient packing and presence of strong-ion dipole interactions in the binary systems. The negative deviation was more pronounced in binary system of [C(4)mim][NTf2] + THE than [C(4)mim][NTf2] + DIO. The values of In eta(m) decrease with rise in the temperature for both systems. The Prigogine-Flory-Patterson (PEP) theory and Extended Real Association Solution Model (ERAS) were employed to correlate experimental V-m(E). (C) 2020 Elsevier B.V. All rights reserved.

Ring-Opening Reaction of Tetrahydrofuran on Ge(100) Surface

The adsorption structures and reaction mechanism of tetrahydrofuran on a Ge(100) surface were investigated through high-resolution photoemission spectroscopy (HRPES) and density functional theory (DFT) calculations. On the basis of our analysis of the HRPES spectra, two adsorption species consisting of a major Ge-(CH2)(4)-O-Ge structure formed via a ring-opening reaction and a minor molecularly adsorbed structure formed via O dative bonding were identified. Our DFT results provided not only the optimized adsorption structures and their corresponding adsorption energies but also the level of the transition state for the pathway from the molecularly adsorbed species to the major adsorption structure. The results confirmed that the adsorption of tetrahydrofuran on the Ge(100) surface is under both kinetic and thermodynamic controls. Our discovery of the ring-opening reaction is an unprecedented result in the field of Ge(100) surface chemistry.

Inorganic clusters as metalloligands: ligand effects on the synthesis and properties of ternary nanopropeller clusters

Redox-active multimetallic platforms with synthetically addressable and hemilabile active sites are attractive synthetic targets for mimicking the reactivity of enzymatic co-factors toward multielectron transformations. To this end, a family of ternary clusters featuring three edge metal sites anchored on a [Co6Se8] multimetallic support via amidophosphine ligands are a promising platform. In this report, we explore how small changes in the stereoelectronic properties of these ligands alter [Co6Se8] metalloligand formation, but also substrate binding affinity and strength of the edge/support interaction in two new ternary clusters, M3Co6Se8L6 (M = Zn, Fe; L(-) = Ph2PN(-)iPr). These clusters are characterized extensively using a range of methods, including single crystal X-ray diffraction, electronic absorption spectroscopy and cyclic voltammetry. Substrate binding studies reveal that Fe3Co6Se8L6 resists coordination of larger ligands like pyridine or tetrahydrofuran, but binds the smaller ligand (CNBu)-Bu-t. Additionally, investigations into the synthesis of new [Co6Se8] metalloligands using two aminophosphines, Ph2PN(H)Pr-i (L-H) and (Pr2PN)-Pr-i(H)Pr-i, led to the synthesis and characterization of Co6Se8L6H, as well as the smaller clusters Co4Se2(CO)(6)L-4(H), Co3Se(mu(2)-PPh2)(CO)(4)L-3(H), and [Co(CO)(3)((Pr2PN)-Pr-i(H)Pr-i)](2). Cumulatively, this study expands our understanding on the effect of the stereoelectronic properties of aminophosphine ligands in the synthesis of cobalt chalcogenide clusters, and, importantly on modulating the push-pull dynamic between the [Co6Se8] support, the edge metals and incoming coordinating ligands in ternary M3Co6Se8L6 clusters.

Explicit Representation of Cation-pi Interactions in Force Fields with 1/r(4) Nonbonded Terms

The binding energies for cation-pi complexation are underestimated by traditional fixed-charge force fields owing to their lack of explicit treatment of ion-induced dipole interactions. To address this deficiency, an explicit treatment of cation-pi interactions has been introduced into the OPLS-AA force field. Following prior work with atomic cations, it is found that cation-pi interactions can be handled efficiently by augmenting the usual 12-6 Lennard-Jones potentials with 1/r(4) terms. Results are provided for prototypical complexes as well as protein-ligand systems of relevance for drug design. Alkali cation, ammonium, guanidinium, and tetramethylammonium were chosen for the representative cations, while benzene and six heteroaromatic molecules were used as the pi systems. The required nonbonded parameters were fit to reproduce structure and interaction energies for gas-phase complexes from density functional theory (DFT) calculations at the.B97X-D/6-311++G(d,p) level. The impact of the solvent was then examined by computing potentials of mean force (pmfs) in both aqueous and tetrahydrofuran (THF) solutions using the free-energy perturbation (FEP) theory. Further testing was carried out for two cases of strong and one case of weak cation-pi interactions between druglike molecules and their protein hosts, namely, the JH2 domain of JAK2 kinase and macrophage migration inhibitory factor. FEP results reveal greater binding by 1.5-4.4 kcal/mol from the addition of the explicit cation-pi contributions. Thus, in the absence of such treatment of cation-pi interactions, errors for computed binding or inhibition constants of 10(1)-10(3) are expected.
