In view of documented activities and potential extensive applications of the antagonistic and agonistic analogs of growth hormone-releasing hormone (GHRH) in various areas of medicine, including the treatment of cancer, infarcted heart, diabetes, wounds and eye diseases, these projects will continue. Our main goal will be further development of analogs of GHRH, which appear to be free of side effects. Newly synthesized antagonists of growth hormone-releasing hormone (GHRH) of AVR class with high antitumor activities will be evaluated for their inhibitory effects on growth of various malignancies, including castration resistant prostate carcinoma (CRPC), small cell and non-small cell lung carcinoma (SCLC and non-SCLC), pancreatic carcinoma, colorectal and gastric cancers, breast, ovarian and endometrial cancers, malignant brain tumors, as well as leukemia. All these cancers express receptors for GHRH to which the anti-tumor GHRH analogs are targeted. The oncological evaluations will be carried out in various human cancer lines xenografted into athymic mice and in vitro. The cancers selected represent major national and international health problems that all affect US veterans and are responsible for a large number of deaths. About 30,000 men with CRPC, die yearly in the USA. We will evaluate experimentally, new approaches for treatment of CRPC, based on new potent AVR class GHRH antagonists. The incidence of these cancers and the mortality rates in VA patients generally reflect similar rates for the US population of corresponding age groups. Therefore, the results of the proposed research will be of benefit to both the male and female VA patient population. Alzheimer’s disease is a serious global health problem. GHRH antagonists of Miami class, such as MIA-690 show beneficial effects in transgenic mouse models of Alzheimer’s disease (AD) and evaluation of the effects of new AVR class GHRH antagonists will continue in collaboration with several VA and non-VA groups. GHRH antagonists of MIA Class and AVR Class will be also tested in models of eye diseases, dyslipidemia, and lung diseases, like fibrosis and sarcoidosis. The investigator will also continue his work on agonists of GHRH of MR Class, such as MR-409, which have been previously synthesized. This work will include the evaluation in some cancers, especially CRPC of recently discovered anti-tumor effects of GHRH agonists mediated by downregulation of GHRH receptors. However, the main evaluations of GHRH agonists will be done in experimental studies in animals for uses in cardiology, treatment of diabetes, wound healing and eye diseases, such as uveitis. Both the agonists and antagonists of GHRH exert antioxidative anti- inflammatory effects. These preclinical studies will be carried out with several groups of expert collaborators. Agonists of GHRH act on cells with receptors for GHRH and in cardiology improve cardiac structure and function. Thus, in collaboration, agonists of GHRH of MR class, such as MR-409, will be subjected to cardiological investigations to determine their therapeutic potential in treatment of heart failure and/or left ventricular (LV) dysfunction, cardiac fibrosis and cardiac hypertrophy. Agonists of MR class will also continue to be evaluated in models of diabetes type I and II since they increase the proliferation of pancreatic islet cells after transplantation and augment insulin output of pancreatic islet cells. Wound healing affects millions of people, particularly veterans, and is improved by GHRH agonists. The overall program is aimed at improving the treatment for various cancers and other diseases and conditions by the use of GHRH analogs and to provide preclinical basis for clinical trials. The findings obtained will be important clinically and should lead to improvements in therapies. The preclinical information acquired will be used to start phase I, II and III clinical trials and apply for IND.

鉴于拮抗和激动类似物的记录活性和潜在的广泛应用， 生长激素释放激素（GHRH）在医学的各个领域，包括癌症的治疗， 在治疗心脏梗塞、糖尿病、创伤和眼疾方面，这些项目将继续进行。我们的主要目标将是进一步 开发GHRH类似物，似乎没有副作用。新合成的拮抗剂 将评价具有高抗肿瘤活性的AVR类生长激素释放激素（GHRH）的 对各种恶性肿瘤生长的抑制作用，包括去势抵抗性前列腺癌（CRPC）， 小细胞和非小细胞肺癌（SCLC和非SCLC）、胰腺癌、结肠直肠癌和 胃癌、乳腺癌、卵巢癌和子宫内膜癌、恶性脑肿瘤以及白血病。所有这些 癌症表达抗肿瘤GHRH类似物所靶向的GHRH受体。肿瘤学 将在异种移植到无胸腺小鼠中的各种人癌细胞系和体外进行评价。的 选定的癌症代表了所有影响美国退伍军人的主要国家和国际健康问题， 造成了大量的死亡在美国，每年约有30，000名CRPC患者死亡。我们将评估 在实验上，基于新的有效AVR类GHRH拮抗剂的治疗CRPC的新方法。 这些癌症的发病率和VA患者的死亡率通常反映了美国的相似率 相应年龄组的人口。因此，建议的研究结果将有利于 男性和女性VA患者人群。阿尔茨海默病是一个严重的全球性健康问题。GHRH 迈阿密类拮抗剂如MIA-690在阿尔茨海默氏症的转基因小鼠模型中显示出有益的作用 将继续合作研究新的AVR类GHRH拮抗剂的作用， 有几个VA和非VA组。MIA类和AVR类的GHRH拮抗剂也将在 眼部疾病、血脂异常和肺部疾病（如纤维化和结节病）的模型。研究者还将 继续他在MR类GHRH激动剂方面的工作，如先前已合成的MR-409。 这项工作将包括对一些癌症，特别是CRPC最近发现的抗肿瘤作用的评估 GHRH受体下调介导的GHRH激动剂。然而，GHRH的主要评价 激动剂将在动物实验研究中进行，用于心脏病学、糖尿病治疗、创伤 治愈和眼部疾病，如葡萄膜炎。GHRH的激动剂和拮抗剂都能发挥抗氧化作用， 炎症效应。这些临床前研究将与几组专家合作进行。 GHRH激动剂作用于具有GHRH受体的细胞，在心脏病学中改善心脏结构和功能。 因此，通过合作，MR类GHRH激动剂（例如MR-409）将接受心脏病学治疗 旨在确定其治疗心力衰竭和/或左心室（LV）的治疗潜力的研究 功能障碍、心脏纤维化和心脏肥大。MR类激动剂也将继续在 I型和II型糖尿病模型，因为它们增加了移植后胰岛细胞的增殖 增加胰岛细胞的胰岛素分泌。伤口愈合影响着数百万人，特别是 退伍军人，并通过GHRH激动剂改善。整个计划旨在改善治疗， 通过使用GHRH类似物治疗各种癌症和其他疾病和病症，并提供临床前基础 用于临床试验。所获得的发现将在临床上具有重要意义，并将导致治疗的改进。 获得的临床前信息将用于启动I、II和III期临床试验，并申请IND。
