Protein tyrosine phosphatase-1B(PTP1B), a negative regulatory factor of insulin signaling, is recognized as a potent target for the therapy of diabetes. Aimed to provide new scaffold to the development of PTP1 B inhibitors and disclose the relationship between configurations of certain positions(3, 4, 5, 6 and 23-position) on the steroidal skeleton and inhibitory activities against PTP1 B, a class of lithocholic acid(LCA) mimics were designed and synthesized. In vitro bioassay against PTP1 B showed that 3β-...
