  Discovery and SAR of a Novel Selective and Orally Bioavailable Nonpeptide Classical Competitive Inhibitor Class of Protein-Tyrosine Phosphatase 1B

  摘要：

  Reversible phosphorylation and dephosphorylation of key proteins on tyrosine residues are important parts of intracellular signaling triggered by hormones and other agents. Recent knock-out studies in mice have identified PTP1B as a potential target for the treatment of diabetes and obesity. As a consequence, a number of academic and industrial groups are aggressively pursuing the development of selective PTP1B inhibitors. In addition, other protein-tyrosine phosphatases (PTPs) appear to be critically involved in major diseases such as cancer and autoimmunity. Given the diversity of PTPs and their potential as drug targets in different diseases, we have taken a broad approach to develop active site-directed selective inhibitors of specific members of this family of enzymes. Using a high throughput screening, we have previously identified 2-(oxalylamino)benzoic acid 3a as a relatively weak but classical competitive inhibitor of several PTPs.(4) On the basis of our early studies, indicating that 3a might be used as a starting point for the synthesis of selective PTP inhibitors, we now present our efforts in expansion of this concept and provide here a number of new chemical scaffolds for the development of inhibitors of different members of the PTP family. Although the core structure of these inhibitors is charged, good oral bioavailability has been observed in rat for some compounds. Furthermore, we have observed enhancement of 2-deoxy-glucose accumulation in C2C12 cells with prodrug analogues.

  The present invention provides novel compounds, novel compositions, methods of their use, and methods of their manufacture, where such compounds are pharmacologically useful inhibitors of Protein Tyrosine Phosphatases (PTPase's) such as PTP1B, CD45, SHP-1, SHP-2, PTP&agr;, LAR and HePTP or the like. The compounds are useful in the treatment of type I diabetes, type II diabetes, impaired glucose tolerance, insulin resistance, obesity, immune dysfunctions including autoimmunity diseases with dysfunctions of the coagulation system, allergic diseases including asthma, osteoporosis, proliferative disorders including cancer and psoriasis, diseases with decreased or increased synthesis or effects of growth hormone, diseases with decreased or increased synthesis of hormones or cytokines that regulate the release of/or response to growth hormone, diseases of the brain including Alzheimer's disease and schizophrenia, and infectious diseases.

  本发明提供了新型化合物、新型组合物、它们的使用方法以及制备方法，其中这些化合物是药理学上有用的蛋白酪氨酸磷酸酶（PTPase's）抑制剂，例如PTP1B、CD45、SHP-1、SHP-2、PTP&agr;、LAR和HePTP等。这些化合物在治疗I型糖尿病、II型糖尿病、糖耐量受损、胰岛素抵抗、肥胖症、免疫功能障碍（包括凝血系统功能失调的自身免疫性疾病）、过敏性疾病（包括哮喘）、骨质疏松症、增生性疾病（包括癌症和牛皮癣）、合成或效应减少或增加的生长激素相关疾病、合成或反应减少或增加的调节生长激素释放或反应的激素或细胞因子相关疾病、包括阿尔茨海默病和精神分裂症在内的脑部疾病以及传染病治疗中有用。
