Effect of oleic acid content and chemical crosslinking on the properties of palm oil‐based polyurethane coatings
Authors: Velayutham T. S. , Abd Majid W. H. , Ng B. K. , Gan S. N. 
Published: November 2012

AbstractPolyurethanes (PU) were prepared by reacting palm oil‐based polyols and aromatic diisocyanate (toluene 2, 4 diisocyanates). The content of oleic acid was varied in the polyester polyols and the hydroxyl value was fixed to be 140 mg KOH g−1. The NCO/OH ratios were varied to 1.2, 1.4, and 1.6. Crosslinking density of the PU was measured by swelling in toluene at room temperature. It was found that the crosslinking increased with decreasing oleic acid content and increasing NCO/OH ratio. The samples were assessed by thermogravimetric analysis, differential scanning calorimetric, and short‐term creep measurements. The highest rupture strength of the PU films was 36 MPa and thermostability improved as the oleic acid content and the NCO/OH ratios were increased in the sample. © 2012 Wiley Periodicals, Inc. J.

Morphological Study of the Sinus Node and Its Artery in Yak
Authors: Duan Deyong , Yu Sijiu , Cui Yan 
Published: November 2012

AbstractThe sinus node of yak has been studied by the histological methods and transmission electron microscopy. The sinus node artery of yak was also determined by the injection‐corrosion casting technique, the angiography, and histological methods. The results showed that the sinus node of yak contained an extensive framework of collagen and two main type cells: pacemaker cells (P cells) and transitional cells (T cells). The P cells had a perinuclear clear zone, contained less myofibrils, and appeared smaller mitochondria than T cells. The T cells were longer and slender than P cells, and had a variety of shapes. At the periphery of sinus node there were many nerve fibers and ganglions. Gap junction did not reveal reaction with anti‐connexin43, but it was detected by electron microscopy in the central part of sinus node of yak. The sinus node artery of yak originated from left coronary artery more frequently (98%) than by right (2%). The artery located at the periphery of sinus node. It had an internal elastic membrane throughout its course, and a large nerve bundle was found running in a longitudinal direction. Anat Rec, 2012. © 2012 Wiley Periodicals, Inc.
Immunocytochemical Localization of the Translocase of the Outer Mitochondrial Membrane (Tom20) in the Human Cochlea

Published: November 2012

AbstractMitochondrial degeneration in the inner ear is likely a contributing factor in age‐related hearing loss and other otopathologies such as Meniere's disease. Most mitochondrial proteins are synthesized in the cytosol and imported through the mitochondrial membranes by translocators. The translocase of the outer membrane (Tom) is the universal entry gate for all proteins that are imported into mitochondria. Altered function of the translocator could alter protein transport into the mitochondria, and disrupt function. In this study, we determined the immunolocalization of Tom20, a major mitochondrial protein import receptor, in microdissected human cochlea frozen sections obtained from postmortem autopsy and celloidin‐embedded archival specimens. We used affinity purified rabbit polyclonal antibodies against Tom20. We also determined the Tom20 immunolocalization in the mouse inner ear. In the human and mouse cochlea, Tom20 was ubiquitously distributed in the organ of Corti, allowing well‐delineated visualization of inner and outer hair cells. Tom20 immunoreactivity localized in the cytoplasm of spiral ganglia neurons. In the inner ear of aged subjects with Meniere's disease, there was decreased expression of Tom20. These results suggest that Tom20 can be used in the inner ear as a marker for mitochondrial protein import. Anat Rec, 2013. © 2012 Wiley Periodicals, Inc.

AbstractVia a Mannich reaction involving a dibenzyliminium species and the titanium enolates of Evans' chiral acylated oxazolidinones the β2‐amino acids (R)‐ and (S)‐Fmoc‐β2homovaline and (R)‐Fmoc‐β2homoleucine are synthesized. These building blocks were used, in combination with commercially available α‐ and β3‐amino acids, for the synthesis of the cyclo‐(αβ3αβ2α)2 peptide 2 and the cyclo‐(αβ2αβ3α)2 peptides 3–5. The peptides 2–5 were screened for their ability to inhibit a small panel of Gram‐negative and Gram‐positive bacterial strains.
Total Synthesis of the Peptaibols Hypomurocin A3 and Hypomurocin A5, and Their Conformation Analysis
Authors: Pradeille Nicolas , Tzouros Manuel , Möhle Kerstin , Linden Anthony , Heimgartner Heinz 
Published: November 2012

AbstractThe total syntheses of hypomurocin A3 and hypomuricin A5 (HM A3 and HM A5, resp.) in solution phase are described. These syntheses have been successfully achieved by applying the ‘azirine/oxazolone method’ to introduce the two Aib‐Pro units into the backbone of these undecapeptaibols in one step with methyl 2,2‐dimethyl‐2H‐azirine‐3‐prolinate as the ‘Aib‐Pro synthon’. The coupling of Z‐protected (Z=(benzyloxy)carbonyl) amino acids or peptide acids with amino acid tert‐butyl esters and of peptide segments was carried out according to the TBTU (=O‐(benzotriazol‐1‐yl)‐N,N,N′,N′‐tetramethyluronium tetrafluoroborate) and HOBt (=1‐hydroxybenzotriazole) protocol. Purification by reversed‐phase HPLC gave the peptides in pure form. The products were characterized by optical rotation, NMR and IR spectroscopy, mass spectrometry, and elemental analysis. The crystal structures of HM A3 and of an octapeptide fragment of HM A5 could be obtained. An NMR analysis was also carried out with HM A3 and HM A5 to determine their conformations in solution. A global structural comparison between the three sequences of HM A1, HM A3, and HM A5 was performed, as well as the HPLC correlation of the natural HM A family and the synthetic samples.
Analogs of the Antituberculous Agent Pyrazinamide Are Competitive Inhibitors of NADPH Binding to M. tuberculosis Fatty Acid Synthase I

Published: November 2012

AbstractAnalogs of pyrazinamide (=pyrazine‐2‐carboxamide; PZA), an essential component of short‐course antituberculous chemotherapy, such as 5‐chloropyrazinamide (5‐Cl‐PZA) act as competitive inhibitors of NADPH binding to purified mycobacterial fatty acid synthase I (FAS I) as shown by Saturation Transfer Difference (STD) NMR studies. In addition, pyrazinoic acid esters (POE) and 5‐Cl‐POE reversibly bind to FAS I with the relatively greater affinity of longer‐chain esters for FAS I, clear from the STD amplification factors. The competitive binding of PZA and 5‐Cl‐PZA clearly illustrates that both agents bind FAS. In contrast to PZA, at low NADPH concentrations 5‐Cl‐PZA is a cooperative inhibitor of NADPH binding.
Bacterial β‐Aminopeptidases: Structural Insights and Applications for Biocatalysis
Authors: Heck Tobias , Geueke Birgit , Kohler Hans‐Peter E. 
Published: November 2012

Abstractβ‐Aminopeptidases comprise a class of enzymes with functional and structural similarities. All members of the β‐aminopeptidases described to date were isolated from bacterial sources. Uniquely, they catalyze the hydrolysis of β3‐ and/or β2‐amino acid residues from amides and peptides that are otherwise considered proteolytically stable. Due to this unusual reactivity with β‐peptide substrates, β‐aminopeptidases have potential to be used as biocatalysts for β‐peptide synthesis and for the resolution of enantiomerically pure β‐amino acids from racemic substrate mixtures. β‐Aminopeptidases are formed from an inactive precursor by posttranslational autoproteolytic cleavage, exposing the catalytic nucleophile at the N‐terminus of the newly formed β‐polypeptide chain. Such an activation step is a characteristic trait of enzymes of the N‐terminal nucleophile (Ntn) hydrolase superfamily. However, classical Ntn hydrolases and β‐aminopeptidases differ by the fold of their catalytic cores and are hence likely to originate from distinct evolutionary ancestors. In this contribution, we review the existing literature on β‐aminopeptidases, including biochemical and functional studies, as well as structural investigations that recently allowed insights into the catalytic mechanisms of precursor processing and β‐peptide conversion.
Preparation of Recoverable Pd Catalysts for Carbonylative Cross‐Coupling and Hydrogenation Reactions

Published: November 2012

AbstractWe report on the synthesis, characterization and catalytic performance of new, supported PdII and Pd0 catalysts. The catalysts are characterized by TEM, XRD, FTIR, X‐ray photoelectron spectroscopy, and vibrating sample magnetometry. The catalysts are found to be active in both forms, PdII and Pd0, for the carbonylative cross‐coupling reaction of aryl iodides with arylboronic acids, and for the hydrogenation of aromatic nitro‐ and unsaturated compounds. The newly developed catalysts are prepared by a synthetic strategy that is similar to the one used for other supported catalysts but are easier to recover—they can be recycled by magnetic separation from liquid phase reactions—and can be used for at least 5 consecutive trials without any decrease in activity.
Palladium‐Catalysed Direct Polyarylation of Pyrrole Derivatives
Authors: Zhao Liqin , Bruneau Christian , Doucet Henri 
Published: November 2012

AbstractThe palladium‐catalysed direct polyarylation of 1‐methylpyrrole and 1‐phenylpyrrole was studied. As the C2 and C5 positions of pyrroles are more reactive for CH bond functionalisation than the C3 and C4 positions, the formation of 2,5‐diarylpyrroles was found to proceed selectively in the presence of 3 equiv. of a variety of aryl bromides. The sequential C2 arylation followed by C5 arylation to prepare non‐symmetrically substituted 2,5‐diarylpyrroles was also studied. For the synthesis of such pyrroles, higher yields were obtained for the couplings with electron‐deficient aryl bromides. The tetraarylation of 1‐methylpyrrole was also achieved. From 4 equiv. of 3,5‐bis(trifluoromethyl)bromobenzene, the 2,3,4,5‐tetraarylated pyrrole was obtained in good yield.
