摘要:
A series of pyrrolo[2,3-c] azepine derivatives was designed, synthesized, and evaluated as a new class of inhibitors against protein tyrosine phosphatase 1B (PTP1B) in vitro. The results demonstrated that compounds bearing a biphenyl moiety were proved to markedly influence the potency of these inhibitors. Particularly, compounds 29, 35 and 36 showed interesting inhibition with IC50 value of 16.36, 14.93 and 13.92 mu M, respectively. (C) 2011 Elsevier Ltd. All rights reserved.
