Compounds of the formula (I) provide pharmacological agents which are inhibitors of PTPases, in particular, the compounds of formula (I) inhibit PTP-1 B and TC PTP, and thus may be employed for the treatment of conditions associated with PTPase activity. The compounds of the present invention may also be employed for inhibition of other enzymes with a phosphotyrosine binding region such as the SH2 domain. Accordingly, the compounds of formula (I) may be employed for prevention or treatment of insulin resistance associated with obesity, glucose intolerance, diabetes mellitus, hypertension and ischemic diseases of the large and small blood vessels. The compounds of the present invention may also be employed in the treatment, prevention or control of a number of conditions that accompany Type 2 diabetes, including hyperlipidemia, hypertriglyceridemia, atherosclerosis, vascular restenosis, irritable bowel syndrome, pancreatitis, adipose cell tumors and carcinomas such as liposarcoma, dyslipidemia, and other disorders where insulin resistance is indicated. In addition, the compounds of the present invention may be employed to treat or prevent cancer, osteoporosis, neurodegenerative and infectious diseases, and diseases involving inflammation and the immune system.
公式(I)的化合物提供了一种药理剂,它们是PTP酶的抑制剂,特别是公式(I)的化合物抑制PTP-1 B和TC PTP,因此可以用于治疗与PTP酶活性相关的疾病。本发明的化合物还可用于抑制具有磷酸酪氨酸结合区域的其他酶,如SH2结构域。因此,公式(I)的化合物可用于预防或治疗与肥胖、葡萄糖不耐受、糖尿病、高血压以及大、小血管缺血性疾病相关的胰岛素抵抗。本发明的化合物还可用于治疗、预防或控制伴随2型糖尿病的许多疾病,包括高脂血症、高三酸甘油脂血症、动脉粥样硬化、血管再狭窄、肠易激综合症、胰腺炎、脂肪细胞瘤和脂肪肉瘤等癌症、血脂异常以及其他表现出胰岛素抵抗的疾病。此外,本发明的化合物还可用于治疗或预防癌症、骨质疏松症、神经退行性疾病、传染病以及涉及炎症和免疫系统的疾病。
