  • Publication number: 20040161399
    Abstract: The present invention discloses a hair growth promoting agent comprising a cyclosporin derivative having an excellent hair growth stimulating ability with little immunosuppressive effect as an active ingredient. In accordance with the invention, there is provided a hair growth promoting agent comprising a cyclosporin derivative represented by Chemical Formula 1 below. The derivatives of the invention were prepared by derivatization of cyclosporins at the amino acid residue 4, N-methyl-L-leucine, and hair growth promoting effects thereof were examined. Such a hair growth promoting agent, comprising a cyclosporin derivative as an active ingredient, exhibits an excellent hair growth effect, while it shows very weak immunosuppressive activity, compared to unmodified cyclosporin A.
