The present invention relates to a method for purifying an immunoglobulin, and more particularly, to a method for purifying an immunoglobulin, which comprises: dissolving immunoglobulin-containing plasma protein fraction I + II +III or fraction II + III; adding caprylate to the solution to cause precipitation; performing dialysis and concentration after removal of the precipitate; performing anion exchange resin and ceramic cation exchange resin purification processes to effectively remove a solvent and detergent added to inactivate viruses; and performing elution while maintaining salt concentration at a constant level to maintain the immunoglobulin polymer content at a low level. According to the method for preparing the intravenous immunoglobulin according to the present invention, a precipitation step of preparing fraction II from fraction I + II + III or fraction II + III as a starting material can be omitted, and problems, including a complicated process and a low yield, which occur in the conventional preparation process employing the polyethylene glycol treatment process, can be solved by use of first sodium caprylate precipitation, anion exchange chromatography and cation exchange chromatography. In addition, when the immunoglobulin purification method according to the present invention is used, the efficiency with which impurities and thrombotic substances are removed can be increased and the immunoglobulin polymer content can be maintained, and thus a stable immunoglobulin with increased quality can be produced.

A composition containing wall teichoic acid-attached peptidoglycan (WTA-PGN) as an active ingredient, a method for preventing or treating Staphylococcus aureus infectious diseases using the composition, and a method for preparing a soluble WTA-PGN which can be used as an active ingredient in the composition are provided. The composition of the present invention can be effectively used for preventing or treating Staphylococcus aureus infectious diseases by opsonophagocytosis due to antigen-antibody reaction and neutrophil-mediated phagocytosis due to T cell activation at the early stage of infection.

The present invention relates to a method for purifying an immunoglobulin, and more particularly, to a method for purifying an immunoglobulin, which comprises: dialyzing and concentrating an immunoglobulin-containing plasma protein fraction II paste; removing thrombotic substances from the dialyzed and concentrated fraction by a purification process using ceramic cation exchange resin; and performing elution while maintaining salt concentration at a constant level to maintain the polymer content of the immunoglobulin at a low level. When the immunoglobulin purification method according to the present invention is used, the efficiency with which impurities and thrombotic substances are removed can be increased and the polymer content of the immunoglobulin can be maintained, and thus a stable immunoglobulin with improved quality can be produced.


A composition comprising recombinant iduronate-2-sulfatase (IDS) and a method for producing a purified recombinant IDS are provided. The glycosylation pattern and formylglycine content of the IDS composition are different from those of ELAPRASE and have superior pharmaceutical efficacy and are safer than the conventional agent and thus can be effectively used for the therapy of Hunter syndrome.


The present invention relates to a composition for preventing and treating cancer-related fatigue, characterized by containing a new processed ginseng powder or a new processed ginseng extract having an increased amount of a ginsenoside constituent, which was previously minute, by preparing a saponin-decomposing enzyme and subsequently using hydrolysis by the prepared saponin-decomposing enzyme and an organic acid. The composition according to the present invention can be very effectively used for preventing and treating cancer-related fatigue, the most destructive and universal side effect, which is caused by cancer itself or occurs in association with the treatment of cancer.


Provided is pyrazole derivatives as a TNIK (Traf2- and NCK-interacting kinase), IKK (I-kappa-B kinase epsilon) and TBK1 (TANK-binding kinase 1) inhibitor; the pyrazole derivative according to the present invention effectively inhibits TNIK, IKK and TBK1, and thus is useful not only as an anticancer agent for the treatment of various cancers including colorectal cancer, breast cancer, CNS cancer, colon cancer, non-small cell lung cancer, kidney cancer, prostate cancer, ovarian cancer, uterus cancer, stomach cancer, liver cancer, skin cancer, lung cancer, brain cancer, bladder cancer, esophageal cancer, pancreatic cancer, thyroid cancer, head and neck cancer, squamous cell carcinoma, osteosarcoma, B-cell or T-cell lymphoma, acute or chronic leukemia and multiple myeloma, but as a therapeutic agent for chronic inflammation.

The present invention relates to a method for diagnosing myotonic dystrophy type 1 or a method for identifying myotonic dystrophy type 1 patients by using a computer processor. The method of the present invention is an early diagnosis method of a genetic disorder having no effective prevention method except prevention in the early months of pregnancy, and can be applied to a method for diagnosing various dominant or recessive genetic disorders in which a specific repeating base sequence of a specific gene is abnormal. According to the method of the present invention, it is possible to take suitable measures related to symptoms, which will occur later, by classifying a genetic carrier and first to third risk groups according to the repetition number of the CTF sequence of 3-noncoding region of the DDMPK gene. Particularly, the method of the present invention numerically provides a genetic carrier or the approximate prevalence of a disease with respect to an unborn baby, thereby allowing the risk of disorders to be accurately understood.


Provided are 7-azaindole or 4,7-diazaindole derivatives as an IKK (I-kappa-B kinase epsilon) and TBK1 (TANK-binding kinase 1) inhibitor. The 7-azaindole or 4,7-diazaindole derivative effectively inhibits IKK and TBK1, and thus is useful not only as an anticancer agent for the treatment of various cancers including colorectal cancer, breast cancer, CNS cancer, colon cancer, non-small cell lung cancer, kidney cancer, prostate cancer, ovarian cancer, uterus cancer, stomach cancer, liver cancer, skin cancer, lung cancer, brain cancer, bladder cancer, esophageal cancer, pancreatic cancer, thyroid cancer, head and neck cancer, squamous cell carcinoma, osteosarcoma, B-cell or T-cell lymphoma, acute or chronic leukemia and multiple myeloma, but as a therapeutic agent for chronic inflammation.

Disclosed are an epitope specific to hepatitis B virus (HBV) and use thereof. The disclosed epitope is a conservative position on which mutagenesis does not occur and, therefore, a composition including an antibody to the foregoing epitope or a vaccine composition including the epitope has very low possibility of causing degradation of curing efficacy due to HBV mutation, thus being very useful for HBV treatment.


Provided is a compound of formula (I) as a TNIK (Traf2- and NCK-interacting kinase), IKK (I-kappa-B kinase epsilon) and TBK1 (TANK-binding kinase 1) inhibitor; the compound according to the present invention effectively inhibits TNIK, IKK and TBK1, and thus is useful not only as an anticancer agent for the treatment of various cancers including colorectal cancer, breast cancer, CNS cancer, colon cancer, non-small cell lung cancer, kidney cancer, prostate cancer, ovarian cancer, uterus cancer, stomach cancer, liver cancer, skin cancer, lung cancer, brain cancer, bladder cancer, esophageal cancer, pancreatic cancer, thyroid cancer, head and neck cancer, squamous cell carcinoma, osteosarcoma, B-cell or T-cell lymphoma, acute or chronic leukemia and multiple myeloma, but as a therapeutic agent for chronic inflammation.
