Novel benzofuran-3-one indole inhibitors of PI3 kinase-α and the mammalian target of rapamycin: Hit to lead studies
摘要:
A series of benzofuran-3-one indole phosphatidylinositol-3-kinases (PI3K) inhibitors identified via HTS has been prepared. The optimized inhibitors possess single digit nanomolar activity against p110 alpha (PI3K-alpha), good pharmaceutical properties, selectivity versus p110 gamma (PI3K-gamma), and tunable selectivity versus the mammalian target of rapamycin ( mTOR). Modeling of compounds 9 and 32 in homology models of PI3K-alpha and mTOR supports the proposed rationale for selectivity. Compounds show activity in multiple cellular proliferation assays with signaling through the PI3K pathway confirmed via phospho-Akt inhibition in PC-3 cells. (C) 2010 Elsevier Ltd.
