(57) [Summary] [Structure] A peptide analog obtained from APP (β amyloid protein precursor) and comprising a minimum activity unit for inhibiting gelatinase A activity, or a peptide analog containing the same, as an active ingredient. It is related to agents. [Effects] Gelatinase A is an in-vivo enzyme involved in cancer metastasis and the like, and if it can inhibit the activity of this gelatinase A, it is expected to prevent cancer metastasis. In addition, gelatinase A, which is one of the inhibitors according to the present invention, Gelatinase A can be qualitatively and quantified using an activity inhibitor. |
