A new method is being proposed for preparing MALDI target plates with a hydrophobic polymer coating and hydrophilic anchors The particles of the MALDI matrix were pre-mixed with a poly[4 5-chfluoro-2 2-bis(trifluoromethyl)-1 3-dioxole-co-tetrafluoroethylene] solution prior to their placement on a mass-spectrometric sample support This technique led to the formation of matrix microspots with a diameter of less than 1 mm inside the polymer The polymer and matrix concentration as well as the amount of suspension placed on the target plate influenced the size and quality of microspots to a great extent The sensitivity of the mass-spectrometric analysis was confirmed by obtaining the mass spectra of fmole concentrations of an apomyoglobin tryptic digest The potential proteomic application of this type of MALDI surface preparation was demonstrated by performing the redox cycle using glutathione and its analogue All reactions were carried out directly on a MALDI plate which accommodates low volumes of reagents and prevents sample loss (C) 2010 Elsevier B V All rights reserved

The 1:1 intermediate generated by the addition of triphenylphosphine to dialkyl acetylenedicarboxylates is trapped by alizarin to produce alkyl 6,11-dihydro-12-hydroxy-2,6,11-trioxo-2H-naphtho[2,3-g]chromene-4-carboxylates in good yields. When ethyl propiolate was used, the reaction afforded ethyl 6,11-dihydro-6,11-dioxoanthra[1,2-d][1,3]-dioxole-2-acetate. The reaction of dialkyl acetylenedicarboxylates, alizarin, and trialkyl phosphites produced dialkyl 2-(dialkoxyphosphoryl)-3-(9,10-dihydro-1-hydroxy-9,10-dioxoanthracen-2-yloxy)succinates.

Catalytic reactions of alpha, beta-conjugated carbonyl compounds have been a practical tool towards the synthesis of different useful heterocyclic compounds. Despite the numerous reactions with carbon-carbon double bond conjugated carbonyls, reactions of acetylenic carbonyls are limited. In this study, efficient dioxole synthesis was carried out via acetylenic aldehydes and butadiene formation was preferred over cyclopropene formation via acetylenic esters as different functional groups on these substrates change the product distribution. Both reaction conditions (such as solvent and temperature) and electrophilic structure of metal carbenoids alter the product distribution; acceptor (A), donor-acceptor (DA), and acceptor-acceptor (AA) functionalized diazo compounds yield different product types over different mechanisms.

The kinetics of entry into and exit from the cavity of cucurbit[7]uril (CB7) was studied by the stopped-flow method in water at various temperatures using pharmaceutically important natural isoquinoline alkaloids as guest compounds. The rate constant of the alkaloid-CB7 complex dissociation was separately determined exploiting the very strong competitive binding of the 1-adamantylammonium cation to CB7. The enthalpy and entropy of activation for the release of berberine from CB7 were significantly lower than those found in the case of the other alkaloids, suggesting different dissociation dynamics. CB7 initially moved from the energetically most stable position encompassing the isoquinoline moiety of berberine to the smaller benzodioxole part, which could leave the macrocycle with less structural distortion. Despite the same thermodynamic parameters of berberine and palmatine inclusion, the latter compound was encapsulated in and set free from CB7 much slower due to the more substantial steric hindrance. The most rapid entry into CB7 and the most exothermic binding were found for epiberberine and coptisine, the alkaloids substituted with the less spacious dioxole ring on their isoquinoline moiety.

Molecular modeling techniques are applied to study the cavity size distributions and transport properties of two very permeable polymers, poly (1-trimethylsilyl-1-propyne) (PTMSP) and a random copolymer of tetrafluoroethylene and 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole (TFE/BDD), which have very similar and large fractional free volumes, but very different permeabilities. Using atomistic models, cavity size (free volume) distributions determined by a combination of molecular dynamics and Monte Carlo methods are consistent with the observation that PTMSP is more permeable than TFE/BDD. The average spherical cavity size in PTMSP is 11.2 angstrom, whereas it is only 8.2 angstrom in TFE/BDD. These cavity size distributions determined by simulation are also consistent with free volume distributions determined by positron annihilation lifetime spectroscopy (PALS). The diffusivity, solubility and permeability Of CO2 in these polymers were also obtained through molecular simulation. The diffusivity and permeability Of CO2 in PTMSP are higher than in TFE/BDD. Good agreement is observed between the simulation and experimental data.

Gas sorption, diffusion, and permeation in poly(2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole-co-tetrafluoroethylene)

The solubility and permeability of H-2, O-2, N-2, CO2, CH4, C2H6, C3H8, CF4, C2F6, and C3F8 in TFE/BDD87, a random copolymer prepared from 87 mol % 2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole [BDD] and 13 mol % tetrafluoroethylene [TFE], are reported as a function of temperature and pressure. Sorption isotherms of all penetrants except hydrogen are concave to the pressure axis and are well described by the dual-mode model. Hydrogen exhibits linear sorption isotherms. In contrast to previous results in hydrocarbon-rich polymers, the solubility of perfluorocarbon penetrants is higher in TFE/BDD87 than that of their hydrocarbon analogues. The solubility of all penetrants in TFE/BDD87 decreases with increasing temperature. Enthalpies of sorption become more negative as penetrant size increases. Fluorocarbon enthalpies of sorption at infinite dilution are significantly more exothermic than those of their hydrocarbon analogues, suggesting more favorable interactions between fluorocarbon penetrants and perfluorinated TFE/BDD87 than between hydrocarbon penetrants and this polymer. Perfluorocarbon permeability coefficients are nearly an order of magnitude lower than those of their hydrocarbon analogues due to the larger size of the fluorocarbons and their subsequently lower diffusivities. The permeability of TFE/BDD87 increases with increasing temperature, indicating that activation energies of permeation (E-p) are positive. E-p values in TFE/BDD87 are smaller than those of conventional glassy polymers. Diffusion coefficients of the lower sorbing gases (O-2, N-2, CO2, CH4, CF4) exhibit a concentration dependence that is consistent with dual-mode transport in unplasticized glassy polymers. For more strongly sorbing C2H6, C3H8, C2F6, and C3F8, diffusion coefficients increase exponentially with increasing penetrant concentration, suggesting plasticization. Activation energies of diffusion in TFE/BDD87 are positive and increase linearly with penetrant diameter squared. Relative to conventional glassy polymers, E-D values in TFE/BDD87 are low. However, E-D is larger than Delta H-S. TFE/BDD87 is easily plasticized by the larger, more soluble penetrants and is susceptible to penetrant-induced conditioning. The level of conditioning is highest for the largest, most soluble penetrant examined (C3F8), and the conditioned state gradually relaxes toward that of the as-cast state.

Identification, Separation and Characterization of Process-Related Impurities of Bifendate Derivative (DB-6), an Investigational Agent Combating Acute Liver Failure

DB-6, with an IUPAC name of (Z)-5-(2,4-di-tert-butyl-6-((2,4-dioxothiazolidin-5-ylidene)methyl)phenyl)-5′-methyl-7,7′-dimethoxy-[4,4′-bibenzo[ d][1,3] dioxole]-5,5′-dicarboxylate,is an investigational agent for acute liver failure. The focus of this study is the identification and characterization of major unknown impurities in DB-6 bulk drug samples. Four major impurities of DB-6 were detected by a high-performance liquid chromatography (HPLC) method and designated as IMP-I, IMP-II, IMP-III and IMP-IV. Accurate masses of these impurities were determined by using a Q-TOF mass spectrometer. Based on chromatographic, spectrometric data and plausible chemical transformation mechanism, the structures of IMP-I, IMP-II, IMP-III and IMP-IV were identified, respectively, as bifendate, (E)-5-(2,4-ditert- butyl-6-((2,4-dioxothiazolidin-5-ylidene) methyl) phenyl)-5′-methyl-7,7′- dimethoxy-[4,4′-bibenzo[d][1,3] dioxole]-5,5′-dicarboxylate, (Z)-5( 3,5-di-tert-butyl-2-hydroxybenzylidene) thiazolidine-2,4-dione and bis(2,4-di-tert-butyl-6-((Z)-(2,4-dioxothiazolidin-5-ylidene) methyl)phenyl)- 7,7′-dimethoxy-[4,4′-bibenzo[d][1,3] dioxole]-5,5′-icarboxylate. The impurities were isolated by preparative-HPLC or preparative high-speed counter-current chromatography and their structures were confirmed by NMR spectroscopy.

Crystal chirality was assigned on the basis of the carbohydrate D-(-)-arabinose which was used to prepare the crystals. Chiral centers C2, C3 and C4 in D-(-)-arabinose are fixed in the densely oxygenated cyclopentane ring at the 1,3-dioxole ring fusion and at the C atom bearing the siloxy functionality. The molecules are involved in two kinds of hydrogen bonding: an intramolecular hydrogen bond exists between O6 and O8-H8′ [O8-H8’…O6; O8-H8′ = 0.76 (4), H8’…O6 = 2.04 (4), O8…O6 = 2.768 (4) angstrom and O8-H8’…O6 = 161 (5)-degrees]; H6′ bonds together two molecules related by a 2(1) screw axis along the a axis [O6-H6’…O8 (x – 0.5, – y + 1.5, – z); O6-H6′ = 0.84 (5), H6’…O8 = 2.08 (5), O6…O8 = 2.917 (4) angstrom and O6-H6’…O8 = 175 (4)-degrees]. The latter interaction results in infinite chains of hydrogen-bonded molecules in the a-axis direction.
