New somatostatin analogs containing the fragments of adamantane, coumarin, tetrahydrocarbazole, and palmitic acid of the general formula R-Phe-D-Trp-Lys(Boc)-Thr-OMe have been synthesized. The structure of the conjugates combines a peptide fragment, which has affinity for somatostatin receptors (sstr), and a nonpeptide fragment, which potentially possesses antitumor activity. Presumably, the compounds
已经合成了含有金刚烷、香豆素、四氢咔唑和棕榈酸片段的新型生长抑素类似物,其通式为 R-Phe-D-Trp-Lys(Boc)-Thr-OMe。偶联物的结构结合了对生长抑素受体 (sstr) 具有亲和力的肽片段和具有潜在抗肿瘤活性的非肽片段。据推测,合成的化合物是sstr的激动剂。肽和非肽片段之间的酰胺键已使用碳二亚胺法和活化酯法形成。偶联物的结构已通过质谱法 (ESI+) 和 1H NMR 光谱法证实。通过对人肺腺癌 (A549)、人前列腺腺癌 (PC3)、人结肠癌 (HCT-116)、人乳腺癌 (MCF7) 和急性人 T 细胞白血病 (Jurkat) 细胞系。已经鉴定了选择性抑制 A549 细胞生长的化合物。
