Abstract
Protein tyrosine phosphatases such as PTP1B and YopH are potential targets for the development of therapeutic agents against a variety of pathological conditions including diabetes, obesity, and infection by the bacterium Yersinia pestis. A focused library of bidentate α-ketoacid-based inhibitors has been screened against several tyrosine phosphatases. Compound 2a has IC(50) values of 43 and 220 nM against YopH and PTP1B, respectively, and shows a 30-fold selectivity for PTP1B over the closely related phosphatase TCPTP.
