Provided are methods and compositions for treating hepatitis virus infections in mammals, especially humans. The methods comprise (1) administering N-substituted-1,5-dideoxy-1,5-imino-D-glucitol compounds in combination with nucleoside antiviral agents, nucleotide antiviral agents, mixtures thereof, or immunomodulating/immunostimulating agents, or (2) administering N-substituted-1,5-dideoxy-1,5-imino-D-glucitol compounds in combination with nucleoside antivirals agents, nucleotide antiviral agents, or mixtures thereof, and immunomodulating/immunostimulating agents.

A method is disclosed for the in vivo treatment of patients having a lysosomal storage disease with a significant central nervous system (CNS) involvement. Said method comprises administration to said patient a small but storage-inhibitory effective amount of an N-alkyl derivative of a 1,5-iminosugar in which said alkyl group contains from about 2 to about 8 carbon atoms and said 1,5-iminosugar is 1,5-dideoxy-1,5-imino-D-glucitol, or 1,5-dideoxy-1,5-imino-D-galactitol, or an O-acylated pro-drug of said 1,5-iminosugar. In an illustrative example, CNS storage of GM2 ganglioside is inhibited in Tay-Sachs mice by administration of 1,5-(butylimino)-1,5-dideoxy-D-glucitol.

摘要:
The invention relates to a method for the long-term stable and well-reproducible spectrometric measurement of the concentrations of components of aqueous solutions, especially of dialysates of interstitial tissue fluids, especially the glucose concentration. The inventive method comprises splitting a measuring beam into two partial beams by means of a beam splitter (2), and guiding one partial beam through a measuring cuvette (3), that is separated from the solution to be measured for example by a diaphragm, or that is connected to a pump system with an exchange path that is separated from the solution to be measured by a diaphragm. The other partial beam is guided through a reference cuvette (4) that is filled with a reference solution. The light intensity of both partial beams is measured and the measured signals are subjected to a symmetrical signal processing, optionally after suitable amplification. The invention further relates to a device for carrying out the inventive method, which device can be especially miniaturized.
摘要:
Disclosed are methods of cell surface activation and inhibition that involve the interaction of an inhibitor of matrix metalloprotease known as TIMP-2, with the enzyme, gelatinase-A (GelA). Critical to the methods of the invention is the discovery of a unique TIMP-2 binding site on the surface of the C-terminal domain (GelA-CTD) of the enzyme, which has been determined to be Asp656, but which can also include other residues in the Ge1A-CTD domain with which Asp656 forms a contiguous surface, namely Gly?651, Phe650¿, and Tyr636. Identification of this binding site provides a useful target for the screening of MMP inhibitors and for prognosis and treatment of diseases in which MMPs are implicated. Compounds which are candidate MMP inhibitors can be structured to competitively inhibit cell surface activation.
