  • Epithelial cell growth promoter
    Patent number: 8304393
    Abstract: It is intended to provide a novel oligopeptide which can be relatively easily produced, has not only a hair growth-stimulating effect but also an effect of promoting the growth of epithelial cells (for example, skin regeneration) and can easily pass through the horny layer to thereby reach the desired target cells in which its effects are to be exerted. Namely, water-soluble oligopeptides containing a proryl isoleucyl glycyl unit or an isoleucyl glycyl serine unit and having from 3 to 7 amino acids and water-soluble salts thereof.
    Type: Grant
    Filed: May 3, 2010
    Date of Patent: November 6, 2012
    Assignee: Patent Technology Development Inc.
    Inventors: Syuichi Oka, Akinori Tsuruda, Yasuhiro Kawano, Mitsuo Suzuki, Satoshi Nakazato

  • UV-induced dermatitis inhibitor and atopic dermatitis inhibitor
    Patent number: 7820625
    Abstract: At least one substance selected from the group consisting of a water-soluble peptide comprising at least one unit selected from the group consisting of an isoleucylglycylseryl unit, a prolylisoleucylglycylseryl [SEQ ID NO: 2] unit, a glycylprolylisoleucylglycylseryl [SEQ ID NO: 6] unit, a glycylprolylisoleucylglycylthreonyl [SEQ ID NO: 7] unit, a prolylisoleucylglycyl unit and a glycylprolylisoleucylglycyl [SEQ ID NO: 1] unit and a water-soluble salt thereof can be used as an UV-induced dermatitis inhibitor or atopic dermatitis inhibitor.
