Potent, Selective, and Orally Bioavailable Inhibitors of Mammalian Target of Rapamycin (mTOR) Kinase Based on a Quaternary Substituted Dihydrofuropyrimidine
文摘
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 Ki < 1.0 nM and were highly (>100脳) 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鈭扨D relationship in a mouse model of cancer.
