title: Inhibition of protein tyrosine phosphatase 1B as a potential treatment of diabetes and obesity.
abstract: Diabetes is a prevalent disease which effects over 150 million people worldwide and there is a great medical need for new therapeutic agents to treat it. Inhibition of protein tyrosine phosphatase 1B (PTP1B) has emerged as a highly validated, attractive target for treatment of not only diabetes but also obesity. Discovery of small-molecule inhibitors has been pursued extensively in both academia and industry and a number of very potent and selective inhibitors have been identified. With X-ray crystallography, the binding interactions of several classes of inhibitors have been elucidated. This has resulted in significant progress in understanding important interactions between inhibitors and specific residues of PTP1B, which could help the design of future inhibitors. However, since the active site of PTP1B that most of these inhibitors bind to is highly hydrophilic, it remains a challenge to identify inhibitors with both excellent in vitro potency and drug-like physiochemical properties which would lead to good in vivo activities.
