A pharmaceutical composition including a pharmaceutically acceptable excipient; and a natural isoflavone of formula (I), a derivative thereof, or a pharmaceutically acceptable salt thereof, the natural isoflavone, the derivative thereof, or the pharmaceutically acceptable salt threof being in a therapeutically effective amount for the treatment of mucopolysaccharidosis.

Provision of a method for accurate diagnosis of mucopolysaccharidoses, including determining the level of glycosaminoglycan in a biological sample with high sensitivity and with ease.A diagnostic method of mucopolysaccharidoses including the following steps (1) and (2):(1) a step including (a) filtering a biological sample with an ultrafiltration filter, digesting the sample on the filter with a glycosaminoglycan-specific enzyme, centrifuging the digested sample to obtain a filtrate, or (b) digesting a biological sample with a glycosaminoglycan-specific enzyme, filtering the sample with an ultrafiltration filter to obtain a filtrate, applying the filtrate obtained by (a) or (b) to a liquid chromatograph / mass spectrometer, and analyzing glycosaminoglycan-derived disaccharides, and(2) a step of diagnosing a subject as having mucopolysaccharidosis, chemically diagnosing effect of treatment of mucopolysaccharidoses, or determining types of mucopolysaccharidoses, on the basis of quantitative concentration data and disaccharide composition obtained in step (1).

This invention provides compositions of active highly phosphorylated human N-acetylgalactosamine-6-sulfatase (GALNS), and pharmaceutical compositions and formulations thereof, methods of producing and purifying GALNS, and its use in the diagnosis, prophylaxis, or treatment of diseases and conditions, including particularly lysosomal storage diseases that are caused by, or associated with, a deficiency in the GALNS enzyme, e.g., Mucopolysaccharidosis IVa (MPS IVa or Morquio A syndrome).

Provided herein are methods and compositions for treating a subject suffering from an enzyme deficiency in the central nervous system (CNS). The bifunctional fusion antibody provided herein comprise an antibody to an endogenous blood brain barrier (BBB) receptor and an enzyme deficient in mucopolysaccharidosis IIIB (MPS-IIIB). The fusion antibodies provided herein comprise alpha-N-acetylgulcosaminidase (NAGLU). The methods of treating an enzyme deficiency in the CNS comprise systemic administration of a fusion antibody provided herein.

The invention provides for nucleotide sequences encoding for a chimeric sulfatase, viral vectors expressing such sequences for gene therapy and pharmaceutical uses of the chimeric expressed protein. The invention is particularly applied in the therapy of mucopolysaccharidosis, preferably type IIIA.

The present invention provides a polypeptide therapeutic agent, useful in enzyme replacement therapy, with increased therapeutic benefits for the central nervous system. The invention provides a method of enhancing the effect of a polypeptide or protein on the central nervous system by the attachment of a short acidic amino acid sequence. Specifically the inventors disclose the attachment of a 4-15 acidic amino acid sequence to human β-glucuronidase by construction of a fusion protein. This molecule is useful in the treatment of type VII mucopolysaccharidosis when administered to a patient.

Disclosed are methods and compositions for reduced immunogenic proteins used in enzyme replacement therapy for lysosomal storage disorders. More specifically disclosed are genetically engineered variants of N-acetylgalactosamine-6-sulfatase (GALNS), which are less immunogenetic then wild-type GALNS, but maintain enzymatic activity, and may be used to treat Mucopolysaccharidosis IVA (Morquio A disease, MPS IVA).

The invention provides compositions and methods for treating Hunter Syndrome.

The invention provides compositions and methods for treating MPS I.

The invention of this patent provides a novel gene therapy drug construct that can be used for type 3A mucopolysaccharidosis, which can effectively express recombinant human heparan-N-sulfatase (SGSH), and is used to prepare genes mediated by adeno-associated virus vectors Therapeutic pharmaceutical products.

The present invention is comprised in the field of glycobiology. In particular, it relates to a method for separating, in biological samples, the fraction bound to or associated with sulfated glycosaminoglycans (GAGs), and the applications thereof in biomedicine, such as for identifying the profile of glycoproteins or the profile of lipids bound to or associated with sulfated GAGs, detecting an alteration in the pattern of glycosylation by sulfated GAGs, identifying biomarkers for the diagnosis, for the prognosis, for monitoring the progression of a disease or of the effect of a therapy, or for identifying compounds suitable for the treatment of a disease. The invention also relates to methods for diagnosing mucopolysaccharidosis and for diagnosing and determining the prognosis of a kidney disease.
