The present invention provides a method of inhibiting a member of a family of Protein Tyrosine Phosphatases (PTPases, PTPs) such as PTP1B, TC-PTP, CD45, SHP-1, SHP-2, PTPα, PTPε, PTPμ, PTPδ, PTPσ, PTPζ, PTPβ, PTPD1, PTPD2, PTPH1, PTP-MEG1, PTP-LAR, and HePTP by exposing said Ptpase member by administration to a host or otherwise to at least one compound with certain structural, physical and spatial characteristics that allow for the interaction of said compound with specific residues of the active site of PTP1B and/or TC-PTP. These compounds are indicated in the management or treatment of a broad range of diseases such as autoimmune diseases, acute and chronic inflammation, osteoporosis, various forms of cancer and malignant diseases, and type I diabetes and type II diabetes, as well as in the isolation of PTPases and in elucidation or further elucidation of their biological function.
本发明提供了一种抑制蛋白酪氨酸磷酸酶(PTPases,PTPs)家族成员(如PTP1B、TC-PTP、CD45、SHP-1、SHP-2、PTPα、PTPε、PTPμ、PTPδ、PTPσ、PTPζ、PTPβ、PTPD1、PTPD2、PTPH1、PTP-MEG1、PTP-LAR和HePTP)的方法,通过将至少一种具有特定结构、物理和空间特征的化合物与PTP1B和/或TC-PTP的活性位点上的特定残基相互作用,使该PTPase成员暴露于宿主或以其他方式进行管理或治疗。这些化合物适用于管理或治疗广泛的疾病,如自身免疫性疾病、急性和慢性炎症、骨质疏松症、各种癌症和恶性疾病、1型糖尿病和2型糖尿病,以及在PTPases的分离和阐明或进一步阐明其生物学功能方面。
