Abstract:

Biocatalysts are increasingly prevalent in the large-scale synthesis of enantiomerically pure compounds. However, many sought-after reactions lack a suitable enzymatic production route. This work describes the development of a novel amine dehydrogenase through the application of directed evolution altering the substrate specificity of an existing leucine dehydrogenase scaffold. Eleven rounds of directed evolution completely altered the enzyme’s specificity and successfully created amination activity. The resulting amine dehydrogenase asymmetrically catalyzes methyl isobutyl ketone and free amm

Abstract:

The intercalation of primary, secondary, tertiary, and aromatic amines into layered TiOCl have been investigated by a variety of methods. The intercalation reaction does not appear to be a redox process. A key step for intercalation of amines into host TiOCl is proposed to be a coordination via nitrogen lone electron pair to Ti$\sp{3+}$ metal centres. Subsequent substitution of the interlayer chloride ions of TiOCl by the amine molecules is strongly dependent on the properties of the organic compounds and their ability to form ammonium salts. Based on X-ray diffraction, fluorescence, elemental

Abstract:

The development of cost-effective and sustainable catalytic methods for the production of enantiomerically pure chiral amines is a key challenge facing the pharmaceutical and fine chemical industries. There is an increasing demand for broadly applicable synthetic methods which deliver the desired amine product in high yield and enantiomeric excess (e.e.). Previously we have described the development of variants of monoamine oxidase from Aspergillus niger (MAO-N) which are able to mediate the complete conversion of racemic amines to the corresponding enantiomerically pure products in a single s

Abstract:

In view of the rising amounts of greenhouse gases in the atmosphere, preventing CO2 emissions has become increasingly important. The combustion of fossil fuels for energy production and transportation is a large contributor to the problem. One of the ways to reduce the amounts of CO2 being released from combustion is carbon capture and storage (CCS). Post-combustion is the capturing method which has been deemed the easiest to apply to existing power plants in a short period of time. Absorption of CO2 by MEA is the most common method used in post-combustion carbon capture, but there are still

Abstract:

The metabolites of the basic tertiary arylaliphatic amine N,N,α-trimethyl-7-phenylbenzenepropanamine (RecipavrinR) from male Wistar rats were characterized by gas chromatography-mass spectrometry (GCMS). The work was undertaken in an attempt to determine the source of a novel metabolite, N-(1-methyl-3,3-diphenylpropyl) formamide. The formamide metabolite was isolated from the bile of recipavrin dosed rats only after hydrolysis with the enzyme β-glucuronidase, suggesting that it arose from a glucuronide conjugated precursor. Recipavrin was chosen for the study based on structural similarity to

Abstract:

<p>Enantiomerically pure amines and alcohols are particularly important synthons for the preparation of pharmaceuticals and agrochemicals. Notwithstanding the advances that have been achieved in asymmetric synthesis, resolution of racemates is probably the most current approach for the preparation of pure enantiomers. On the other hand, resolution processes suffer from disadvantages of low yields caused by the loss of at least 50% of the undesired isomer. Among the attractive methods for avoiding the drawbacks of resolution processes is inversion of configuration of the unwanted isomer. Althou

O trabalho foi realizado em duas etapas, sendo a primeira a obtenção dos derivados, seguido de estudos da interação com o plasmídeo VR 1412 (pDNA) que expressa a β-galactosidase. A primeira etapa de síntese envolve a modificação de quitosana pela introdução de grupos amino, seguido pela ligação de

Abstract:

O processo de destilação do petróleo bruto é geralmente sujeito à atividade corrosiva dos equipamentos pelos ácidos, naturalmente presentes no petróleo. Este problema da corrosão pode ser atenuado pela adição de misturas de aminas neutralizantes que são inibidores da corrosão. Porém, esta adição significa um custo adicional ao processamento de petróleo. Para reduzir este custo direto da injeção de aminas o presente trabalho tem como objetivo aplicar a minimização do custo de misturas de aminas, utilizando dois diferentes métodos numéricos de otimização. Para isto foi utilizado um software dese
