    Abstract:
    A series of inhibitors of mTOR kinase based on a quaternary-substituted dihydrofuropyrimidine was designed and synthesized. The most potent compounds in this series inhibited mTOR kinase with K(i) < 1.0 nM and were highly (>100×) selective for mTOR over the closely related PI3 kinases. Compounds in this series showed inhibition of the pathway and antiproliferative activity in cell-based assays. Furthermore, these compounds had excellent mouse PK, and showed a robust PK-PD relationship in a mouse model of cancer.
