Methods for increasing D-Serine concentration and reducing concentration of the toxic products of D-Serine oxidation, for enhancing learning, memory and/or cognition, or for treating schizophrenia, Alzheimer's disease, ataxia or neuropathic pain, or preventing loss in neuronal function characteristic of neurodegenerative diseases involve administering to a subject in need of treatment a therapeutically effective amount of a compound of formula I, or a pharmaceutically acceptable salt or solvate thereof:
wherein
    • [0001]
    • R1 and R2 are independently selected from hydrogen, halo, nitro, alkyl, acyl, alkylaryl, and XYR5;
    • [0002]
    • or R1 and R2, taken together, form a 5, 6, 7 or 8-membered substituted or unsubstituted carbocyclic or heterocyclic group;
    • [0003]
    • X and Y are independently selected from O, S, NH, and (CR6R7)n;
    • [0004]
    • R3 is hydrogen, alkyl or M+; M is aluminum, calcium, lithium, magnesium, potassium, sodium, zinc ion or a mixture thereof;
    • [0005]
    • Z is N or CR4;
    • [0006]
    • R4 is from selected from hydrogen, halo, nitro, alkyl, alkylaryl, and XYR5;
    • [0007]
    • R5 is selected from aryl, substituted aryl, heteroaryl and substituted heteroaryl;
    • [0008]
    • R6 and R7 are independently selected from hydrogen and alkyl; n is an integer from 1 to 6;
    • [0009]
    • at least one of R1, R2 and R4 is other than hydrogen; and
    • [0010]
    • at least one of X and Y is (CR6R7)n. D-serine or cycloserine may be coadministered along with the compound of formula I.

Method for quantitatively detecting content of intermediate in production process of recombinant human interferon alpha by affinity chromatography,

The invention relates to a method for quantitatively detecting the content of an intermediate in the production process of recombinant human interferon alpha by affinity chromatography. The method forquantitatively detecting the content of the intermediate in the production process of the recombinant human interferon alpha by affinity chromatography comprises the following steps that (1) engineering bacteria expressing the recombinant human interferon alpha is constructed; and (2) the engineering bacteria is fermented, and the target protein expressed in the form of soluble protein or an inclusion body is separated and purified, wherein the protein purification comprises crude purification and refined purification, a crude protein is obtained by ammonium sulfate salting-out precipitation,the crude protein is purified by DEAE anion exchange column chromatography to obtain the intermediate, the content of the recombinant human interferon alpha in the intermediate is quantitatively detected by a monoclonal antibody affinity chromatography column. The method is suitable for quantitatively detecting the intermediate in the production process of recombinant human interferon alpha and recombinant integrated interferon, and has the advantages of simple, rapid and accurate operation, and can improve the cognition degree and control degree of people on the production process accordingto the obtained interferon concentration data, so that reliable, rapid, direct and easy evaluation of key links of interferon production is achieved so as to realize the purpose of accurate quality control.
