The present invention provides stable metastin derivatives having excellent biological activities (a cancer metastasis suppressing activity, a cancer growth suppressing activity, a gonadotropic hormone secretion stimulating activity, sex hormone secretion stimulating activity, etc.).
By substituting the constituent amino acids of metastin with specific amino acids, the metastin derivatives of the present invention achieve more improved blood stability, solubility, etc., reduced gelation tendency, improved pharmacokinetics, as well as exhibit an excellent cancer metastasis suppressing activity or a cancer growth suppressing activity. The metastin derivatives of the present invention also have a gonadotropic hormone secretion suppressing activity, sex hormone secretion suppressing activity, etc.
本发明提供了稳定的metastin衍生物,具有优异的生物活性(癌转移抑制活性、癌症生长抑制活性、促性腺激素分泌活性、性激素分泌刺激活性等)。通过用特定的氨基酸替换metastin的组成氨基酸,本发明的metastin衍生物实现了更好的血液稳定性、溶解度等,减少了凝胶化倾向,改善了药代动力学,并表现出优异的癌转移抑制活性或癌症生长抑制活性。本发明的metastin衍生物还具有抑制促性腺激素分泌活性、性激素分泌抑制活性等。
