Abstract: The present invention relates to a composition including an anthocyanin-fucoidan complex formed by ionic bond between anthocyanin and fucoidan as an active ingredient, and more particularly, it is confirmed that the anthocyanin-fucoidan complex in which anion of the fucoidan, which is a natural extract having high biocompatibility and biodegradability, is ionically bonded with a cation of the anthocyanin improves the stability and the solubility of the anthocyanin even in acidic conditions in vivo, thereby increasing the immune activity in vivo and therefore it is intended to provide the anthocyanin-fucoidan complex as an immune enhancer, an immune-cancer agent and an anticancer adjuvant composition for alleviating side effects of anti-cancer agents.

Abstract: The present invention relates to a use of an anthocyanin-anionic polysaccharide complex for preventing or treating influenza virus A infection and, more specifically, to a pharmaceutical composition, a food/health functional food/health aid food composition, and a quasi-drug composition, each comprising an anthocyanin-anionic polysaccharide complex as an active ingredient for preventing or treating influenza virus A infection diseases. A composition comprising an anthocyanin-anionic polysaccharide complex as an active ingredient provided in the present invention exhibits excellent anti-viral activity against influenza virus A and as such, can find very advantageous applications in developing an agent for prevention or treatment of diseases caused by influenza virus A infection.

Abstract: The present invention relates to a composition for preventing, ameliorating, or treating gastritis or peptic ulcer, comprising an anthocyanin-negatively charged polysaccharide complex as an active ingredient and, more specifically, to a composition for preventing, ameliorating, or treating gastritis or peptic ulcer, comprising an anthocyanin-negatively charged polysaccharide complex as an active ingredient, the composition exhibiting a synergistic effect as compared to anthocyanins or each of negatively charged polysaccharides. The composition comprising an anthocyanin-negatively charged polysaccharide complex as an active ingredient provided by the present invention exhibits a significantly excellent effect of relieving lesions of gastritis or peptic ulcer, and thus can be very effectively used in the development of a composition for preventing, ameliorating, or treating gastritis or peptic ulcer.

Abstract: The present invention relates to a compound having TrkA inhibitory activity and a pharmaceutical composition for preventing or treating pain containing the same as an active ingredient. The compound provided in one aspect of the present invention has excellent TrkA inhibitory activity and exhibits excellent pain inhibitory effects in an animal model of pain after a surgery, and thus can be effectively used as an analgesic.
