  • Publication number: 20210147482
    Abstract: The present invention relates to a peptide for inhibiting bone resorption and, more specifically, to a peptide for inhibiting bone destruction by inhibiting the differentiation and activity of osteoclasts. According to the present invention, a peptide for inhibiting bone resorption can inhibit bone destruction by inhibiting the differentiation and activity of osteoclasts, and thus can be used as a therapeutic agent for various bone diseases caused by an excessive increase in the activity of osteoclasts.

  • Patent number: 10821065
    Abstract: The present invention relates to: a composition for inhibiting biofilms, containing, as an active ingredient, a peptide derived from human ?-defensin-3; and a method for inhibiting biofilms by using the composition. The peptide according to the present invention inhibits bacterial biofilms even when used alone and exhibits a remarkably increased biofilm inhibitory effect when used in combination with a conventional dental therapeutic agent, and has an effect of preventing a tooth discoloration side effect caused by a conventional dental therapeutic agent.

  • Patent number: 9884084
    Abstract: The present invention relates to a bone regeneration or bone formation promoting pharmaceutical composition comprising muramyl dipeptide, an analog thereof, a derivative thereof or a pharmaceutically acceptable salt thereof. In contrast to existing passive therapeutic agents which center on bone absorption suppression based on mechanisms for reducing osteoclast functionality, the composition comprising muramyl dipeptide of the present invention promotes the differentiation of osteoblasts, which are bone forming cells, and can advantageously be used in various diseases where bone formation is required as an active therapeutic agent that does not affect osteoclast.
