The invention provides a stable metastin derivative having excellent biological activities (a cancer metastasis-inhibiting activity, a cancer proliferation-inhibiting activity, a gonadotropin secretion-promoting activity, a sex hormone secretion-promoting activity, etc.). By replacing the constituent amino acids of metastin with specific amino acids in the metastin derivative of the present invention, the blood stability and solubility of the metastin derivative can be more improved, the gel tendency of the metastin derivative can be reduced, the pharmacokinetics of the metastin derivative can be improved, and the metastin derivative can exhibit an excellent cancer metastasis-inhibiting activity and cancer proliferation-inhibiting activity. The metastin derivative can also exhibit a gonadotropin secretion-inhibiting activity, a sex hormone secretion-inhibiting activity, etc.
该发明提供了一种稳定的metastin衍生物,具有优秀的生物活性(如癌症转移抑制活性、癌细胞增殖抑制活性、促性腺激素分泌活性、促性激素分泌活性等)。通过将metastin的构成氨基酸替换为本发明的metastin衍生物中的特定氨基酸,可以进一步改善metastin衍生物的血液稳定性和溶解性,减少metastin衍生物的凝胶倾向,改善metastin衍生物的药代动力学,并使metastin衍生物表现出优秀的癌症转移抑制活性和癌细胞增殖抑制活性。metastin衍生物还可以表现出促性腺激素分泌抑制活性、促性激素分泌抑制活性等。
