  5,6-二氨基尿嘧啶甲酰胺的结构和构象研究——生物活性黄嘌呤衍生物的前体

  摘要：

  8-Arylethynylxanthine 衍生物是有效的选择性腺苷 A2A 受体拮抗剂，代表了帕金森病、阿尔茨海默病和癌症免疫疗法的（潜在）疗法。6-Amino-5-amidouracil 衍生物是合成此类黄嘌呤的重要前体。我们注意到在许多尿嘧啶衍生物中出现了意外的 NMR 信号重复。在这里，我们利用动态和二维 NMR 光谱、密度泛函理论计算和 X 射线分析对结构多样的 6-氨基-5-甲酰胺双嘧啶进行了详细的分析研究，以解释这些有价值的药物中间体的意外特性。

  对位黄嘌呤类似物（1,7-二取代的黄嘌呤）和其他在3位未取代的黄嘌呤的合成：腺苷受体的结构活性关系。

  摘要：

  开发了用于制备各种3-未取代的黄嘌呤的合成方法，包括对黄嘌呤类似物（1,7-二取代的黄嘌呤）和1,8-二取代的黄嘌呤。1-取代的黄嘌呤的甲硅烷基化，然后在7-位的烷基化提供了一种简便的途径生产对黄嘌呤类似物。三（三甲基甲硅烷基）-6-氨基尿嘧啶的区域选择性烷基化提供了3-取代的6-氨基尿嘧啶，其通过标准方法转化为1,8-二取代的黄嘌呤。3-取代的5-环戊烷羧酰胺基和5-（苯甲酰基氨基）-6-氨基尿嘧啶的闭环需要剧烈的反应条件。在这些和其他具有1、3、7、8和9位取代基的黄嘌呤的结合测定中，确定了对大脑A1和A2腺苷受体的亲和力。为了在腺苷受体上具有高亲和力，必须在1位进行取代。1，3-二取代的黄嘌呤通常比1，7-二取代的黄嘌呤具有更高的亲和力。1,8-二取代的黄嘌呤对腺苷受体具有高亲和力。一些对A1受体具有高度选择性。

  The invention relates to derivatives of the general formulae I and II to processes for the production thereof, to pharmaceutical preparations containing said compounds and/or physiologically compatible salts, or solvates which can be produced therefrom as well as to the pharmaceutical use of said compounds, the salts, or solvates thereof as adenosine receptor antagonists, in particular for the treatment of neurodegenerative disorders, e.g. stroke, amylotrophic lateral sclerosis, dementia, Alzheimer's disease, Parkinson's disease, ischemia/reperfusion injury, inflammation, and/or neurological disorder. The blockade of adenosine receptors could also be useful for other indications regarding the metabolism, e.g. diabetic retinopathy, diabetes mellitus, hyperbaric oxygen-induced retinopathy and/or obesity. Applications could also be the treatment of allergic diseases and autoimmune diseases, including mast cell degranulation, asthma, bronchoconstriction, pulmonary fibrosis, inflammatory or obstructive airways disease and/or chronic obstructive pulmonary disease (COPD). In addition, they could be used to treat cancer, e.g. proliferating tumor, cell proliferation disorders, angiogenesis, lung cancer, breast cancer, pancreatic cancer, thyroid cancer, skin cancer, vascular endothelial cancer, cancer of the central nervous system, esophageal cancer, cancer of the larynx, gastrointestinal cancer, colon cancer, colorectal cancer, rectal cancer, liver cancer, renal cancer, prostate cancer, bladder cancer, cervical cancer, ovarian cancer, endometrial cancer, melanoma, squamous cell carcinoma, basal cell carcinoma, non-small cell lung cancer selected from squamous cell carcinoma, adenocarcinoma, large cell carcinoma, adenosquam- ous carcinoma and/or undifferentiated carcinoma. The diseases associated with adenosine receptors are also diabetes, diarrhea, inflammatory bowel disease and/or gastrointestinal tract disorders. Adenosine receptor antagonists could be effective for treating a hepatic disease or condition for reducing fat deposition in the liver or fibrosis of the liver. The use of compounds of general formulae I and II can be associated with many applications e.g., scleroderm arthritis, atherosclerosis, urticaria, myocardial infarction, myocardial reperfusion after ischemia, vasodilation, hypertension, hypersensitivity, myocardial ischemia, heart attack and/or retinopathy of prematurity.
