Patent number: 7521473Abstract: 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.Type: GrantFiled: February 23, 2005Date of Patent: April 21, 2009Assignee: WyethInventors: Jinbo Lee, Zhao-Kui Wan, Douglas P.
