  Discovery and SAR exploration of a novel series of imidazo[4,5-b]pyrazin-2-ones as potent and selective mTOR kinase inhibitors

  摘要：

  We report here the discovery of a novel series of selective mTOR kinase inhibitors. A series of imidazo[ 4,5-b]pyrazin-2-ones, represented by screening hit 1, was developed into lead compounds with excellent mTOR potency and exquisite kinase selectivity. Potent compounds from this series show >1000-fold selectivity over the related PI3K alpha lipid kinase. Further, compounds such as 2 achieve mTOR pathway inhibition, blocking both mTORC1 and mTORC2 signaling, in PC3 cancer cells as measured by inhibition of pS6 and pAkt (S473). (C) 2011 Elsevier Ltd.
