-Y, or a pharmaceutically acceptable salt thereof. The peptides bind selectively to the somatostatin subtype receptor type-5 and elicit an agonist effect from the somatostatin subtype receptors. The peptides are useful for treating a variety of diseases, including Cushings Syndrome, gonadotropinoma, hyperparathyroidism, Paget's disease, VIPoma, nesidioblastosis, hyperinsulinism, gastrinoma, Zollinger-Ellison Syndrome, hypersecretory diarrhea related to AIDS and other conditions, irritable bowel syndrome, pancreatitis, Crohn's Disease, systemic sclerosis, thyroid cancer, psoriasis, hypotension, panic attacks, sclerodoma, small bowel obstruction, gastroesophageal reflux, duodenogastric reflux, Graves' Disease, polycystic ovary disease, upper gastrointestinal bleeding, pancreatic pseudocysts, pancreatic ascites, leukemia, meningioma, cancer cachexia, acromegaly, restenosis, hepatoma, lung cancer, melanoma, inhibiting the accelerated growth of a solid tumor, decreasing body weight, treating insulin resistance, Syndrome X, prolonging the survival of pancreatic cells, fibrosis, hyperlipidemia, hyperamylinemia, hyperprolactinemia and prolactinemia.
本发明涉及公式(I)的环肽:X-A1-cyclo(D-Cys-A3-A4-Lys-A6-A7)-A8-Y或其药学上可接受的盐。这些肽选择性地结合到生长抑素亚型受体类型5,并从生长抑素亚型受体引起激动剂效应。这些肽可用于治疗多种疾病,包括库欣综合症、促性腺激素瘤、甲状旁腺功能亢进症、帕盖特病、VIP瘤、内生胰岛瘤、高胰岛素血症、胃泌素瘤、佐林格-埃利森综合症、与艾滋病及其他疾病相关的高分泌性腹泻、肠易激综合症、胰腺炎、克罗恩病、系统性硬化症、甲状腺癌、银屑病、低血压、惊恐发作、硬皮病、小肠梗阻、胃食管反流、十二指肠胃反流、格雷夫斯病、多囊卵巢症、上消化道出血、胰腺假囊肿、胰腺腹水、白血病、脑膜瘤、癌症恶病质、嗜铬细胞瘤、再狭窄、肝癌、肺癌、黑色素瘤、抑制实体瘤的加速生长、减轻体重、治疗胰岛素抵抗、X综合症、延长胰岛细胞的存活、纤维化、高脂血症、高淀粉酶血症、高催乳素血症和催乳素血症。
