In this study, production of 3-HP via malonyl-CoA was investigated by using metabolically engineered Escherichia coli carrying heterogeneous acetyl-CoA carboxylase (Acc) from Corynebacterium glutamicum and codon-optimized malonyl-CoA reductase (MCR) from Chloroflexus aurantiacus. Three engineere...
The fatty acid biosynthetic pathway generates highly reduced carbon based molecules. For this reason fatty acid synthesis is a target of pathway engineering to produce novel specialty or commodity chemicals using renewable techniques to supplant molecules currently derived from petroleum. Malony...
Suppression of body weight and eating disorders, such as anorexia, are one of the major symptoms of psychiatric disorders such as depression. However, the mechanisms of weight loss and reduced appetite in depressive patients and in animal models of depression are largely unknown. In this study, ...
SummaryAlterations in cardiac energy metabolism after a myocardial infarction contribute to the severity of heart failure (HF). Although fatty acid oxidation can be impaired in HF, it is unclear if stimulating fatty acid oxidation is a desirable approach to treat HF. Both immediate and chronic m...
The effect of sporicidal fumigation with methyl bromide or methyl iodide on the functionality of valuable electronic equipment was evaluated using desktop computers as surrogates under target conditions of 200–250 mg/L fumigant for 48 h at 24–30 °C and 75–85% RH. Methyl iodide fumigation dam...
Titanium-containing zeolite-based catalysts have been synthesized and investigated as catalysts in methyl(phenyl)sulfide oxidation with hydrogen peroxide. A hierarchical TS-1 prepared by the secondary templating and a layered TS-1 without and with silica and silica-titania pillars have been stud...
Complex technologies in the production of fine chemicals bring together various connected processes, each bringing specific green chemistry challenges. A valuable mixture arises in the stereoselective hydrogenation of methyl-acetoacetate (MAA) to (R)- and (S)- methyl 3-hydroxybutyrate (∑MHB) ov...
Radiosynthetic optimization is crucial in routine PET production but is often neglected in literature. Small changes in the radiochemical procedure can increase the yield significantly and reduce time fluctuation within the synthetic procedure enabling better planning and product release on time...
The terminal > CS group in 1,3-dithiole-2-thione-4,5dithiolate (dmit) ligand of (dppe)Pt(dmit) (dppe: 1,2-bis(diphenylphosphino)ethane) is known to be coordinated to Hg2 + ion. This is clearly shown by the bathochromic shift of the π → π⁎ transition band in H2O/CH3CN solution (1:1 v/v). The b...
The Ullmann coupling of amines with aryl iodide and bromides has been carried out efficiently using Pd(OAc)2/1,2-bis(diphenylphosphino) ethane [DPPE] in toluene as a solvent. The effects of various parameters such as temperature, solvent, base, catalyst loading and metal–ligand ratio on the rea...
The reaction of mercury(II) halides with 1,2-bis(diphenylphosphino)ethane monoxide (dppeO) in 1:1 molar ratio yielded P,O-coordinated polymers having the empirical formula [HgX2(dppeO)]n [X = Cl (1), Br (2), I (3)]. In contrast, the reaction between the same reactants in a 1:2 molar ratio yielde...
A zinc coordination polymer, [ZnI2{Ph2P(O)-CH2CH2-P(O)Ph2}]n (1), has been prepared, which features a one-dimensional concavo-convex chain with alternative ZnI2 and 1,2-bis(diphenylphosphino)ethane dioxide (dppeO2) moieties. The dppeO2 ligand adopts the bridging coordination mode between two zin...
Radical anion salt {CoI(dppe)2CO}+(C60•−)⋅0.5C6H4Cl2⋅0.5C6H14 (1, dppe: bis(diphenylphosphino)ethane) has been obtained at the C60 and CoII(dppe)Cl2 reduction by NaCpCo(CO)2. Cobalt is positioned in the center of a triangular bipyramid in {CoI(dppe)2CO}+ with two phosphorus and one carbon equato...
Crystals in the isostructural series Au2(μ-dppe)X2 (dppe is 1,2-bis(diphenylphosphino)ethane, X = Cl, Br, I) form centrosymmetric, dimeric structures with two short Au⋯Au contacts between the component molecules. We found no evidence for a second polymorph for any member of the Au2(μ-dppe)X2 s...
A novel 1D square-helical coordination polymer [ZnI2(μ2-dppe)]n (1) was synthesized by the reaction of ZnI2 with 1,2-bis(diphenylphosphino)ethane (dppe), while zigzag chains [MX2(μ2-dppe)]n were obtained by using smaller anions (Cl− and Br−) and larger metal ions (Cd2+ and Hg2+).
The work described in this paper involves the synthesis and structural characterization of Ni(II) complexes derived from dihydroxybenzaldehyde thiosemicarbazones (H3L1, H3L2, H3L3, H3L4) and 1,2-bis(diphenylphosphino)ethane (dppe). Ligands and their Ni(II) complexes were characterized by element...
Hydrogen (H)-bonding interaction was introduced into a poly(ethylene oxide)-b-poly(tert-butyl acrylate) (PEO-b-PtBA) block copolymer (BCP) by partial hydrolysis of tBA units into acrylic acid (AA) ones, in order to compete with the segregation force between the PEO and PtBA blocks. It was found ...
Poly(tert-butyl acrylate) (PtBA) was grafted to the surface of poly(ethylene-co-acrylic acid) (EAA) film and the pendant groups of the tethered PtBA were modified to create chemically tailored surface modifying layers. The carboxylic acid groups in the copolymer film served as the grafting sites...
Hydrolysis and thermal decomposition of polyacrylamide tert-butyl acrylate (PAtBA) copolymer were investigated. Carbon-13 nuclear magnetic resonance (13C NMR) spectroscopy was used to monitor the structural changes of the PAtBA. Hydrolysis of the amide groups occurred only after the complete con...
Poly[(2-ethylhexyl acrylate)-ran-(tert-butyl acrylate)]-block-poly(2-cinnamoyloxyethyl acrylate) or P(EXA-r-tBA)-PCEA was synthesized by atom transfer radical polymerization. Reactivity ratios of EXA and tBA for copolymerization were determined. The specific refractive index increments of six di...
