Abstract: Abstract: Protein tyrosine phosphatase 1 B (PTP1B) is a typical member of non-receptor PTP family. PTP1B plays an important role in the negative regulation of insulin signaling pathway. It has been proved to be a novel target for diabetes and obesity. Inhibition of PTP1B抯 activity could improve the sensitivity of insulin signaling. The discovery of highly effective inhibitors of PTP1B has a promising application in diabetes and obesity therapy.
Key words: PTP1B; insulin signaling pathway; negative regulation; diabetes and obesity; inhibitors of PTP1B
