The present invention relates to an antiviral composition comprising any one selected from the group consisting of chlorine, phosphocholine, cytidine triphosphate, CDP-choline, phosphorylcholine, and phosphatidylcholine. The antiviral composition is harmless to the human body and exhibits an excellent inhibitory effect on virus proliferation. Therefore, it can be applied to a pharmaceutical composition for preventing or treating viral diseases as well as a health functional food, a quasi-drug composition, and a feed composition for preventing or ameliorating viral diseases.

Antiviral composition containing material involved in phosphatidylcholine synthesis pathway

The present invention relates to a flavonoid compound having an antiviral activity, more particularly to a flavonoid compound obtained by extractingwith methanol and separating/purifying with chromatography, a method for efficient extraction and purification of the same and an antiviral composition comprising the compound as an active ingredient.

Flavonoid compound having an antiviral activity

The present invention relates to a monoclonal antibody specific for N-myc downstream regulated gene 2 (NDRG 2) protein, a cell line producing the monoclonal antibody, a method for measuring a quantity and quality of NDRG 2 protein, and a protein chip using the same. In the present invention, NDRG 2, a cancer-related factor is specifically expressed in dendritic cells differentiated from a monocyte of human peripheral blood. Accordingly, the monoclonal antibody specific for the NDRG 2 protein, the protein chip comprising the same and the method for measuring a quantity and quality of the NDRG 2 protein by using the same can be applied to elucidate characteristics of the dendritic cell and perform a research on the NDRG 2. Therefore, the present invention may help clinically to investigate and treat intractable diseases and cancers using the dendritic cell.
