摘要
Protein tyrosine phosphatase 1B (PTP1B) has been proposed to be an effective target for the treatment of both type II diabetes and obesity. However, no PTP1B inhibitor has come into clinic application. Herein, we report mixed 3,3′-bisindoles as novel PTP1B inhibitors with low micromole-ranged inhibitory activity. The best active compound 9f inhibited PTP1B activity with an IC50 of 2.79 µM. Meanwhile, it had low cytotoxicity and enhanced glucose uptake in vitro. Further studies demonstrated that some of these active compounds had a specific selectivity over other PTPs. Computational analysis further showed the binding mode of compound 9f with the active pocket of PTP1B. Our studies provide a novel scaffold for further development of more promising PTP1B inhibitors and potential drugs for type II diabetes and obesity.
