Amphiphilic dipyrrinones: methoxylated [6]-semirubins

Replacing the typical beta-alkyl substituents of [6]-semirubin and [6]-oxosemirubin, two intramolecularly hydrogen-bonded bilirubin analogs, with methoxy groups produces amphiphilic dipyrrinones. Synthesized from the respective 9H-dipyrrinones prepared by base-catalyzed condensation of 3,4-dimethoxy-pyrrolin-2-one with the appropriate pyrrole alpha-aldehyde, the 2,3-dimethoxy and 2,3,7,8-tetramethoxy analogs of [6]-semirubin are yellow-colored dipyrrinones that form intramolecularly hydrogen-bonded monomers in CDCl3, as deduced from H-1 NMR NH chemical shifts. They are monomeric in CHCl3, as determined by vapor pressure osmometry. In contrast, in the solid, X-ray crystallography reveals supramolecular ribbons of intermolecularly hydrogen-bonded (dipyrrinone to dipyrrinone and acid to acid) 2,3,7,8-tetramethoxy-[6]-semirubin. The latter is approximately 20 times more soluble in water than the parent [6]-semirubin with four beta-methyl groups. (C) 2009 Elsevier Ltd. All rights reserved.

Tribological properties of hydrogenated nitrile rubber in confrontation with hard particles under different axial loads

The influence of different axial loads on the tribological properties of Hydrogenated Nitrile Rubber (HNBR) under oil-based mud containing hard particles is studied through experimental and theoretical approaches. Friction and wear tests were performed by using pin-on-disc friction pairs. The findings indicate that the tribological properties of HNBR vary with axial load and wear time. The total friction coefficient can be divided into an adhesion term, a hysteresis term and an abrasive term through the analysis of tribological mechanism. The hysteresis term is due to micro-strain on the HNBR surface and overall deformation of the HNBR specimen. The variation of tribological properties can be well explained through the above theory and the hysteresis term is the main influence factor.

Preparation and physical properties of intrinsic low-k polyarylene ether nitrile with enhanced thermo-stability

Polyarylene ether nitrile (PEN) random copolymers were prepared from 6AF, BHPF, and 2, 6-dichlorobenzonitrile according to the nucleophilic aromatic substitution polymerization. The chemical structure of PEN random copolymers was characterized by the FT-IR and H-1-NMR spectrum, respectively. The thermal properties of the PEN random copolymers were investigated by using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The resulting PEN copolymers have excellent thermal stability with high glass transition temperature (T-g) ranging from 187? to 271? and the 5% weight loss temperature (T-5%) of PEN copolymers greater than 490? in nitrogen atmospheres. Meanwhile, the PEN films have excellent mechanical property, the tensile strength ranges from 55 to 95 MPa. Moreover, the dielectric properties of the PEN random copolymers were investigated by dielectric tests. The dielectric constants (k) and loss tangent (tan delta) of PEN (PEN-6-AF/BHPF100) film is only 2.3 and 0.03 at 1 kHz, respectively. More importantly, the dielectric properties were found to be relatively stable until the T-g, which can be attributed to the existence of BHPF units in the molecular backbone.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 13472-00-9. Name: 4-(2-Aminoethyl)aniline.

Synthesis of Novel 3D-Rich alpha-Amino Acid-Derived 3-Pyrazolidinones

Synthetic approaches towards novel 3-pyrazolidinone derivatives functionalized at positions N(1) and/or C(5) were studied. 5-Aminoalkyl-3-pyrazolidinones were prepared in four steps from N-protected glycines via Masamune-Claisen homologation, reduction, O-mesylation, and cyclisation with a hydrazine derivative. The free amines were prepared by acidolytic deprotection. Title compound was also prepared by ‘ring switching’ transformation of N-Boc-pyrrolin-2(5H)-one with hydrazine hydrate. Hydrogenolytic deprotection of 5-(N-alkyl-N-Cbz-aminomethyl) pyrazolidine-3-ones followed by cyclisation with 1,1′-carbonyldiimidazole (CDI) gave two novel representatives of perhydroimidazo[1,5-b] pyrazole, which is an almost unexplored heterocyclic system. Amidation of 3-oxopyrazolidine-5-carboxylic acid gave the corresponding carboxamides in moderate yields. Diastereomeric non-racemic carboxamides obtained from (S)-AlaOMe and (S)-ProOMe were separated by MPLC.

Characterization of amino acid on glutathione adducts of cis-2-butene-1,4-dial, a reactive metabolite of furan

Metabolic activation of the hepatocarcinogen furan yields metabolites that react covalently with proteins, cis-2-Butene-1,4-dial is a microsomal metabolite of furan, This reactive aldehyde is thought to be the toxic metabolite that is responsible for the carcinogenic activity of furan. In order to characterize the chemistry by which this unsaturated dialdehyde could alkylate proteins, the products formed upon reaction of cis-2-butene-1,4-dial with model nucleophiles in PH 7.4 buffer were investigated, N-alpha-Acetyl-L-cysteine (AcCys) reacts with cis-2-butene-1,4-dial to form N-substituted pyrrolin-2-one adducts. N-Acetyl-L-cysteine (AcCys) reacts rapidly with cis-2-butene-1,4-dial to form multiple uncharacterized products. The inclusion of AcLys in this reaction mixture yielded an N-substituted 3-(S-acetylcysteinyl)pyrrole adduct which Links the two amino acid residues. Related compounds were isolated when cis-2-butene-1,4-dial and glutathione (GSH) were combined. In this case, cis-2-butene-1,4-dial cross-linked two molecules of GSH resulting in either cyclic or acyclic adducts depending on the relative GSH concentration. Incubation of furan with rat liver microsomes in the presence of [glycine-2-H-3]GSH led to the formation of radioactive peaks that coeluted with synthetic standards for the bisgluthathione conjugates. These studies demonstrate that the reactive cis-2-butene-1,4-dial formed during the microsomal oxidation of furan reacts rapidly and completely with amino acid residues to farm pyrrole and pyrrolin-2-one derivatives. Therefore, this metabolite is a likely candidate for the activated furan derivative that binds to proteins. The ease with which cis-2-butene-1,4-dial cross-links amino acids suggests that pyrrole-thiol cross-links may be involved in the toxicity observed following furan exposure.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
