Usage

Chemical Properties

white fine crystalline powder, odorless; soluble in acid or alkali solution, slightly soluble in water, insoluble in ethanol, ether and other organic solvents.

Uses

DL-asparagine is a racemic mixture of the non-essential amino acids, L and D-aparagine. It is generally used in growth-media for bacteria-growth. DL-Asparagine monohydrate can also be used to synthesize other salts such as DL-asparaginium perchlorate, DL-asparaginium nitrate and dimethyl DL-aspartate.

Preparation

DL-Asparagine monohydrate was synthesized by dissolving maleic anhydride in 1,4-dioxane solution and refluxing with benzylamine after ammonolysis, followed by catalytic hydrogenation.

Definition

ChEBI: An alpha-amino acid in which one of the hydrogens attached to the alpha-carbon of glycine is substituted by a 2-amino-2-oxoethyl group.

Preparation and purification method of amino acid compound

The invention relates to the field of industrial organic synthesis, in particular to a preparation and purification method of an amino acid compound. The method comprises the following steps that (1)alpha-amino nitrile compounds or hydantoin compounds or mixtures thereof are heated to react to obtain alpha-amino acid salt under the condition that volatile alkali and a suitable solvent exist; (2)after the alpha-amino acid salt obtained in step (1) is distilled, the alpha-amino acid salt is recrystallized in an organic solvent to obtain the alpha-amino acid compound. According to the method, reaction conditions are mild, materials can be recycled, and introduction of metal ions and use of ammonium carbonate salt are avoided, so that post-treatment is simple and no waste salt is generated.

Method for the production of high-level soluble human recombinant interferon alpha in e. coli and vectors useful for such a production

Method for the production of high-level soluble human recombinant interferon alpha protein (rhuIFNα) in E. coli and vectors useful for such a production. Said method comprises the steps of: (1) Transforming an E. coli selected in the group consisting of E. coli protease deficient host strains, and E. coli reductase deficient host strains, with a recombinant expression vector comprising the sequence encoding the glutathione-S-transferase (GST), a junction sequence including a recognition site for a specific protease and a sequence able to encode an interferon alpha (IFN alpha) protein under the control of an inducible promoter, said vector encoding a GST-IFN alpha fusion protein (2) Expressing said interferon alpha protein in conditions comprising the induction of the expression with 0.1 mM-0.5 mM IPTG and a growth temperature of 25° and/or 37°C, depending on said E. coli strain and (3) Isolating the expressed IFN alpha protein.
