Docking and quantum mechanic studies on cholinesterases and their inhibitors

Docking studies and density functional theory (DFT) calculations were made for 88 N-aryl derivatives and for some acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) residues. Based on this information, some compounds were synthesized and tested kinetically in vitro as AChE inhibitors. Finally, some chemical properties of the N-aryl derivatives were calculated: partition coefficient (pi) and molecular electrostatic potentials (MESPs) whereas their electronic effects (rho) were taken from the literature. The results showed that all compounds act inside the AChE gorge, making pi-pi interactions and hydrogen bonds with Trp86 and Ser203 and by high HOMO energies of Ser2003 and high LUMO energies of N-aryl derivatives. These theoretical calculations for AChE are in agreement with the experimental data, whereas such calculations for BChE do not show the same behavior which could be due to in spite of both cholinesterase enzymes displaying similar functional activities they do possess important structural differences at their catalystic sites.

Thermal and electrical behavior of hybrid thermosets based on epoxy and maleimide resins cured with p-aminobenzoic acid

Two thermoset systems based on maleimides and diglycidyl ether of bisphenol A (DGEBA) cured with p-aminobenzoic acid were characterized in terms of thermal and electrical behavior. Thermal characterization has been undertaken by means of thermogravimetric analysis in nitrogen atmosphere up to 600C using simultaneous thermogravimetric/Fourier transform infrared/mass spectrometry (TG/FT-IR/MS) analysis. In the first stage of thermal degradation, the global kinetic parameters [activation energy (Ea) and preexponential factor (log A1 (s?1))] were calculated using the isoconversional method of Friedman. The energies variation as well as the shape of the differential thermal analysis curves suggests that the thermal decomposition process occurred in multiple stages. The evolved gases analysis was conducted by simultaneous TG/FT-IR/MS coupled techniques. Dielectric relaxation spectroscopy characterization was also made.

Synthesis and evaluation of novel 2,3,5-triaryl-4H,2,3,3a,5,6,6a- hexahydropyrrolo[3,4-d]isoxazole-4,6-diones for advanced glycation end product formation inhibitory activity

The synthesis of some biologically interesting pyrrolo-isoxazolidine derivatives was accomplished by the 1,3-dipolar cycloaddition reaction of substituted azomethine N-oxides 1 with substituted N-aryl maleimides 2 leading to the formation of new stereoisomeric 2,3,5-triaryl-4H,2,3,3a,5,6,6a- hexahydropyrrolo[3,4-d]isoxazole-4,6-dione derivatives 3 in excellent yields. The synthesized compounds have been screened for their advanced glycation end (AGE) product formation inhibitory activity on the basis of their ability to inhibit the formation of AGEs in the bovine serum albumin (BSA)-glucose assay. All the synthesized compounds have been found to exhibit significant activity against AGE formation.

Solid-phase synthesis of cleavable N-arylmaleimides: Applications in 1,3-dipolar cycloaddition and in thiol scavenging

(matrix presented) An efficient solid-phase synthesis of polymer-supported N-arylmaleimides has been developed. Various N-arylmaleimidobenzoic acids (MBA) were elaborated onto Rink and SASRIN resins by reaction of the aniline precursors with maleic anhydride followed by facile cyclative dehydration of the resulting maleimic acids. Applications of these acid-cleavable MBA resins in the solid-phase synthesis of highly decorated pyrrolidines and as thiol scavengers are presented.

Selectivity control by chemical modification of the recognition sites in two-point binding molecularly imprinted polymer

We demonstrated the possibility of modifying the selectivity of a two-point binding imprinted polymer by chemical modification of the binding sites inside the cavities. We used a thermally reversible bond for the preparation of the monomer-template complex, which allowed us to remove the template easily by means of a simple thermal reaction and to simultaneously introduce various functional groups into the cavity. A phenylmaleimide having an azidocarbonyl group was reacted with diethylstilbestrol (DES, template) to yield a monomer, where the template was linked to two polymerizable maleimido groups via a thermally reversible urethane bond. The polymerization of the monomer was carried out in the presence of ethylene glycol dimethacrylate (EGDMA) by the initiation with 2,2-azobis(isobutyronitrile) (AIBN) at 54C in DMF. The polymers were refluxed in 1,4-dioxane in the presence of a nucleophile such as water, methanol, or aniline. In this extraction step, the template molecules were removed from the polymer matrix, and simultaneously the isocyanato groups, which were generated by the thermal cleavage of the urethane bond, were converted to amino, urethane, or urea groups through their reaction with water, methanol, or aniline, respectively. The specific recognition ability of the imprinted polymers for the template and its structural analogues was dependent on the space between the two binding points as well as on the nature of the functional group. This method is especially propitious for developing artificial receptors for molecules lacking strongly interactive groups.

Synthesis and properties of 1,3,4-oxadiazole-containing high-performance bismaleimide resins

Two novel bismaleimide (BMI) monomers containing 1,3,4-oxadiazole, i.e., 5-tert-butyl-1,3-di[5-(4-maleimidophenyl)-1,3,4-oxadiazole-2-yl]benzene (Buoxd) and 4,4?-[5-(4-maleimidophenyl)-1,3,4-oxadiazole-2-yl]diphenyldimethyl silane (Sioxd), were designed, synthesized and copolymerized with 4,4?-bismaleimidodiphenylmethane (BMDM) to yield a new series of high-performance bismaleimide resins. Both monomers obtained are readily soluble in common organic solvents, such as dichloromethane and chloroform, enabling an easy solution processing. The thermal properties of the two monomers were carefully studied by the differential scanning calorimetry (DSC), optical microscopy and thermogravimetric analysis (TGA, simultaneous DSC). The BMI resins based on a mixture of Buoxd (or Sioxd) and BMDM in a weight ratio of 10% were prepared. DSC investigations showed that the thermal curing of the BMI resins could be accomplished at a lower temperature than the thermal curing temperatures of Buoxd and Sioxd, and the thermal processing window, i.e., the temperature range between the melting transition and thermal curing process, was over 26 C. The thermal properties and thermal mechanical properties of the resulting BMI resins were investigated by DSC, thermogravimetric analysis (TGA) and dynamic mechanical analysis (DMA). No glass transition temperature was found in the range of 50-350 C, and very good thermal stability (Td > 490 C in nitrogen) and high thermo-oxidative stability (Td > 460 C in air) were revealed. Composites composed of the above BMI resins and glass cloth were also prepared, which showed high bending modulus (>1.6 GPa) at a very high temperature (e.g., 400 C).
