  名称：

  2-(1H-Imidazol-4-yl)ethanamine and 2-(1H-pyrazol-1-yl)ethanamine side chain variants of the IGF-1R inhibitor BMS-536924

  摘要：

  A series of IGF-1R inhibitors is disclosed, wherein the (m-chlorophenyl) ethanol side chain of BMS-536924 (1) is replaced with a series of 2-(1H-imidazol-4-yl)ethanamine and 2-(1H-pyrazol-1-yl)ethanamine side chains. Some analogs show improved IGF-1R potency and oral exposure. Analogs from both series, 16a and 17f, show in vivo activity comparable to 1 in our constitutively activated IGF-1R Sal tumor model. This may be the due to the improved protein binding in human and mouse serum for imidazole 16a and the excellent oral exposure of pyrazole 17f. (C) 2008 Elsevier Ltd. All rights reserved.
