  Probing acid replacements of thiophene PTP1B inhibitors

  摘要：

  The following account describes our systematic effort to replace one of the carboxylate groups of our diacid thiophene PTP1B inhibitors. Active hits were validated using enzymatic assays before pursuing efforts to improve the potency. Only when the C2 carboxylic acid was replaced with another ionizable functional group was reversible and competitive inhibition retained. Use of a tetrazole ring or 1,2,5-thiadiazolidine-3-one-1,1-dioxide as a carboxylate mimetic led to the discovery of two unique starting series that showed improved permeability (PAMPA) and potency of the order of 300 nM. The SAR from these efforts underscores some of the major challenges in developing small molecule inhibitors for PTP1B. (c) 2007 Elsevier Ltd. All rights reserved.

  Protein tyrosine phosphatases (PTPases) such as PTP1B can play a role in regulating a wide variety of cellular responses such as insulin signaling. Substituted thiophene compounds such as, for example, 2-carboxyl, 3-carboxymethoxy, 5-aryl substituted thiophenes, can inhibit PTP1B and thereby induce greater insulin sensitivity. Accordingly, PTP1B inhibition can provide an alternate treatment for PTPase-mediated disorders such as diabetes.

  蛋白酪氨酸磷酸酶（PTPases）如PTP1B可以在调节多种细胞反应中发挥作用，例如胰岛素信号传导。取代噻吩化合物，例如2-羧基、3-羧甲氧基、5-芳基取代的噻吩，可以抑制PTP1B，从而增加胰岛素敏感性。因此，PTP1B抑制可以作为PTPase介导的疾病（如糖尿病）的替代治疗方法。
