  • Patent number: 10568931
    Abstract: Provided is a treatment composition for damage treatment and regeneration promotion of corneal epithelial cells containing gintonin as an active ingredient which is glycolipoprotein or its aggregate isolated from ginseng. Since the gintonin as a drug containing high-concentration LPA has an effect of increasing the concentration of LPA in damaged cornea and inducing the proliferation of corneal epithelial cells to rapidly and significantly restore the damage of the cornea, the composition of the present disclosure can be usefully used as drugs for treatment of corneal erosion and corneal ulcer or equivalent therapeutic agents for corneal injury in humans and animals.
    Type: Grant
    Filed: March 8, 2017
    Date of Patent: February 25, 2020
    Assignee: GINTONIN KU BIOTECH CO., LTD.

  • Publication number: 20140234868
    Abstract: The present invention relates to glycolipoprotein gintonin, isolated and identified from ginseng, as a natural medicinal-plant-derived ligand acting on LPA1 (lysophosphatidic acid; 1- or 2-acyl-sn-glycerol-3-phosphate), LPA2, LPA3, LPA4 and LPA5 receptors whose efficacy is exhibited physiologically/pharmaceutically via an interaction with subset receptors [LPA1(edg-2), LPA2(edg-4), LPA3(edg-7), LPA4, PLA5] in the EDG (endothelial differentiation gene) family in G protein-coupled receptors (GPCRs) present in the cell membranes of animals including humans.

  • Patent number: 8748422
    Abstract: The present invention relates to a pharmaceutical composition containing one or more quinazoline compounds as an active ingredient, which has antagonistic activity against serotonin 5-HT3A and is effective for the prevention and treatment of central nervous system (CNS) diseases, including emesis, nausea, alcoholism, drug abuse, depression, compulsive neurosis, anxiety, seizure, Alzheimer's disease, Parkinson's disease, Huntington's chorea, psychosis, schizophrenia, suicidal tendency, sleep disorder, appetite disorder and migraine.

  • Patent number: 8563052
    Abstract: Disclosed are the novel glycolipoprotein gintonin isolated and identified from ginseng, a method for preparing the same, and uses thereof. Gintonin causes a transient increase in intracellular free Ca2+ level, which in turn activates endogenous Ca2+-activated chloride channel to elevate intracellular calcium levels. Therefore, the novel glycolipoproteins are useful in the therapy and prophylaxis of calcium deficiency-associated diseases as well as effectively inducing calcium-dependent physiological activities, including adaptogenic activity, immunostimulatory activity, aphrodisiac activity, neuroprotection and neuroactivation, angiogenesis, and antidiabetic activity.
