摘要:
Die vorliegende Erfindung betrifft ein Verfahren zur Stabilisierung eines Enzyms durch Lagerung des Enzyms in Gegenwart eines stabilisierten Coenzyms. Weiterhin betrifft die vorliegende Erfindung ein mit einem stabilisierten Coenzym stabilisiertes Enzym sowie dessen Verwendung in Testelementen zum Nachweis von Analyten.
摘要:
Compounds of the general formula: wherein R is H, an acyl group or a hydrocarbyl group containing up to 6 carbon atoms, have cytotoxic activity against several tumours. The 4-hydroxylamino compound can be obtained directly from the corresponding 2,4-dinitro compound by selective chemical reduction or by the action of a nitroreductase obtainable from Walker tumour cells. The 2,4-dinitro compound is substantially devoid of cytotoxic activity except in relation to Walker tumour cells and hence can act as a prodrug in regimes where a prodrug is localised in vivo in the regions of a tumour to be treated and is then activated to the cytotoxic 4-hydroxylamino compound under the influence of the enzyme.
摘要:
The present invention relates to a method for stabilizing an enzyme by storing an enzyme in the presence of a stabilized coenzyme. The present invention further relates to an enzyme stabilized with a stabilized coenzyme and to the use thereof in test elements for detecting analytes.
摘要:
The present invention provides a method capable of effectively treating various diseases associated with energy excess, such as obesity, diabetes, metabolic syndromes, degenerative diseases and mitochrondrial dysfunction-related diseases, via elevation of an NAD(P) + ZNAD(P)H ratio by increasing an NAD(P) + concentration in vivo or in vitro through use of NAD(P)H as a substrate or coenzyme by oxidoreductase such as NAD(P)H:quinine oxidoreductase (NQO1), a method of screening a drug for the same and a therapeutic drug.
摘要:
Les composés de la formule générale (I), dans laquelle R représente H, un groupe acyle ou un groupe hydrocarbyle contenant jusqu'à 6 atomes de carbone, ont une activité cytotoxique contre plusieurs tumeurs. On peut obtenir directement le composé 4-hydroxylamino à partir du composé 2,4-dinitro correspondant par réduction chimique sélective ou par l'action d'une nitroréductase que l'on peut obtenir à partir de cellules tumorales de Walker. Le composé 2,4-dinitro est sensiblement dépourvu d'activité cytotoxique excepté à l'égard des cellules tumorales de Walker, et donc il peut faire office de promédicament dans des régimes dans lesquels un promédicament est localisé in vivo dans les régions d'une tumeur à traiter, il est alors activé pour devenir le composé 4-hydroxylamino cytotoxique sous l'effet de l'enzyme.

Embodiments of the present disclosure relate to NADP-dependent oxidoreductase compositions, and electrodes, sensors and systems that include the same. Also provided are methods for making the compositions and for detecting and/or measuring analytes with NADP-dependent oxidoreductase compositions.
摘要:
Disclosed is a method for purifying a protein, comprising steps of: preparing a sample containing a fusion protein containing an amino acid sequence of a peptide tag and an amino acid sequence of a target protein; and separating contaminant proteins contained with the fusion protein in the sample and the fusion protein in the sample, wherein the peptide tag contains 12 or more acidic amino acid residues.
