Abstract: A composition comprising a naphthoquinone-based compound as an active ingredient and uses thereof are disclosed. The composition is effective for preventing or ameliorating fatigue, cachexia, pain, cognitive decline, and hematopoietic stem cell reduction which are side effects related to anticancer drug treatment. The naphthoquinone-based compounds, dunnione and ?-lapachone, reduce the secretion and production of inflammatory cytokines which are increased by the anticancer drug treatment, and prevent fatigue, cachexia, cognitive decline, and hematopoietic stem cell reduction which are side effects associated with anticancer drug treatment.

Abstract: A pharmaceutical composition containing, as active ingredients, a naphthoquinone-based compound, and at least one selected from among an immune checkpoint inhibitor and an immunogenic cell death inducer, is disclosed. The pharmaceutical composition has a significantly higher anticancer effect compared to the case where each formulation is administered alone. Accordingly, an anticancer synergistic effect of inhibiting the growth in cancer cells and inhibiting the metastasis of the cancer cells, in which an anticancer effect is insignificant when the existing anticancer agent is administered alone, may be expected. Therefore, the composition containing the naphthoquinone-based compound may be usefully used as a drug for preventing or treating cancer, together with the immune checkpoint inhibitor and/or the immunogenic cell death inducer.

Abstract: A new use of dunnione compound, a pharmaceutically acceptable salt thereof, a prodrug thereof, a solvate thereof, or an isomer thereof as an effective ingredient for prevention or alleviation of hair loss is disclosed. The dunnione compound, a pharmaceutically acceptable salt thereof, a prodrug thereof, a solvate thereof, or an isomer thereof, in an animal model, showed an effective reduction of hair thinning as well as an effective reduction in loss of hair follicles and inner root sheaths. Thus, the duunione compound, a pharmaceutically acceptable salt thereof, a prodrug thereof, a solvate thereof, or an isomer thereof can be used effectively to treat hair loss and/or loss of hair follicles and inner root sheaths, promoting hair regrowth. The hair loss may be caused by anticancer therapy.

Abstract: Disclosed is a prevention and treatment of pancreatitis including administering a naphthoquinone-based compound, a pharmaceutically acceptable salt, a prodrug, a solvate, or an isomer thereof. Particularly, the naphthoquinone-based compounds ?-lapachone and dunnione can reduce the pancreatic weight/body weight ratio, which is increased by pancreatitis; reduce the increased activities of digestive enzymes (amylase and lipase); reduce the expressions of cytokines (IL-1? (interleukin-1? and MCP-1); reduce or inhibit the inflammation, edema, and cell necrosis of the pancreatic tissues; and inhibit the lung damage caused by pancreatitis. Therefore, the naphthoquinone-based compound, pharmaceutically acceptable salt, prodrug, solvate, or isomer thereof can be effectively used for the prevention and treatment of pancreatitis mediated diseases.

Abstract: The present invention relates to a composition comprising a naphthoquinone-based compound as an active ingredient, for preventing or ameliorating fatigue, cachexia, pain, cognitive decline, and hematopoietic stem cell reduction which are side effects related to anticancer drug treatment.

Abstract: The present invention relates to a composition for the prevention and treatment of pancreatitis comprising a naphthoquinone-based compound, a pharmaceutically acceptable salt, a prodrug, a solvate, or an isomer of the same. Particularly, the naphthoquinone-based compounds ?-lapachone and dunnione can reduce the pancreatic weight/body weight ratio, which is increased by pancreatitis; reduce the increased activities of digestive enzymes (amylase and lipase); reduce the expressions of cytokines (IL-1? (interleukin-1?) and MCP-1); reduce or inhibit the inflammation, edema, and cell necrosis of the pancreatic tissues; and inhibit the lung damage caused by pancreatitis. Therefore, the naphthoquinone-based compound, the pharmaceutically acceptable salt, the pro-drug, the solvate, or the isomer thereof can be effectively used as a composition for the prevention and treatment of pancreatitis.

Abstract: The present invention relates to a composition for treating or preventing hearing loss comprising naphthoquinone-based compounds.

Abstract: The present invention provides polynucleotides derived from cDNA of novel type of hepatitis C virus named Korean type hepatitis C virus (KHCV), polypeptides encoded therein, and antibodies directed against the polypeptides; and also provide diagnostics and vaccines employing any of the above materials as active ingredient(s).

Abstract: The present invention relates to the epitopes of hepatitis C virus (HCV) core protein and non-structural 3 protein (NS3), and the epitopes of envelope protein, epitopes of non-structural 4 protein, and the epitopes of HCV non-structural 5 protein and a recombinant protein comprising the same; processes for producing the recombinant proteins; an agent for diagnosing antibodies against hepatitis C virus in a putative serum sample, which comprises said recombinant proteins; and a process for diagnosing hepatitis C by using the agent.

Abstract: A novel saponin component having a molecular weight of about 956 daltons, a process for isolating the saponin component from the bark of Quillaja saponaria Molina, a vaccine formulation comprising the saponin component as an immune adjuvant, a method for increasing the immune response to an antigen by employing an adjuvant composition comprising saponin component and a second adjuvant.
