observation that the activity of gonadotropin-releasing hormone III (GnRH-III) in the suppression of growth of MDA-MB-231 and MCF-7 breast cancer cells surpasses that of GnRH and other analogs thereof, analogs of GnRH-III were synthesized to investigate the structural basis for the improved antitumor activity. Compounds synthesized include analogs with changes in the central sequence in which GnRH-III differs
观察到促性腺激素释放激素III(GnRH-III)在抑制MDA-MB-231和MCF-7乳腺癌细胞生长方面的活性超过了GnRH及其类似物,GnRH-III的类似物为合成以研究改善的抗肿瘤活性的结构基础。合成的化合物包括在中心序列(其中GnRH-III与GnRH不同)和C端和N端区域发生变化的类似物。结果表明,Asp6和Lys8之间的盐桥稳定了GnRH-III的活性构象,并显示了Trp7的重要性。用D-Ala-NH2取代C端Gly-NH2的耐受性不高,但用乙酰胺替代则可耐受。
